New class of compounds protect brain cells from traumatic brain injury
A new class of compounds has now been shown to protect brain cells from the type of damage caused by blast-mediated traumatic brain injury (TBI). Mice that were treated with these compounds 24-36 hours after experiencing TBI from a blast injury were protected from the harmful effects of TBI, including problems with learning, memory, and movement.
Traumatic brain injury caused by blast injury has emerged as a common health problem among U.S. servicemen and women, with an estimated 10 to 20 percent of the more than 2 million U.S. soldiers deployed in Iraq or Afghanistan having experienced TBI. The condition is associated with many neurological complications, including cognitive and motor decline, as well as acquisition of psychiatric symptoms like anxiety and depression, and brain tissue abnormalities that resemble Alzheimer's disease.
"The lack of neuroprotective treatments for traumatic brain injury is a serious problem in our society," says Andrew Pieper, M.D., Ph.D., senior study author and associate professor of psychiatry, neurology, and radiation oncology at the University of Iowa Carver College of Medicine. "Everyone involved in this work is motivated to find a way to offer hope for patients, which today include both military personnel and civilians, by establishing a basis for a new treatment to combat the deleterious neuropsychiatric outcomes after blast injury."
It is known that TBI, as well as certain neurodegenerative diseases, damages axons - the tendril-like fibers that sprout from brains cells (neurons) and form the connections called synapses. In TBI, axon damage is followed by death of the neuron. The new study, published Sept. 11 in the journal Cell Reports, shows that a group of compounds, called the P7C3 series, blocks axon damage and preserves normal brain function following TBI.
Pieper led the team of scientists that discovered the P7C3 compound several years ago at UT Southwestern Medical Center. Subsequent studies showed that the root compound and its active analogs protect newborn neurons from cell death and also protect mature neurons in animal models of neurodegenerative diseases, including Parkinson's disease and amyotrophic lateral sclerosis (ALS).
The researchers have also previously shown efficacy of P7C3 molecules in brain injury due to concussion, and plan to investigate whether these compound might be applicable in stroke as well, given that there appear to be common factors mediating neuronal cell death in these conditions.

Two Vaccines Help Cut Bacteria That Cause Meningitis, Study Finds
Two new vaccines can reduce the spread of meningitis by reducing the number of meningitis-causing bacteria that people carry, according to a new study.
Researchers tested the two vaccines -- MenACWY-CRM and 4CMenB -- on volunteers aged 18 to 24. MenACWY-CRM cut meningitis-causing bacteria populations in the nose and throat by 39 percent and 4CMenB lowered those populations by 20 to 30 percent.

New Drug May Fight Serious Respiratory Virus in Infants
An experimental drug shows promise in treating respiratory syncytial virus (RSV), a leading cause of pneumonia in infants, researchers report.
"We are finally making major progress in being able to treat human RSV infections -- the world's second leading cause of serious viral pneumonia, second only to influenza virus," said study author Dr. John DeVincenzo, a professor of pediatrics at the University of Tennessee College of Medicine in Memphis.
"There is no current treatment or vaccine for RSV pneumonia, and so patients were previously forced to get over the virus by themselves," he said. RSV is the leading cause of hospitalization among infants in the United States, the researchers noted.
In this small study of 140 adults, the drug, dubbed GS-5806, reduced the amount of the virus in the systems of those who received the medication.
"For the first time, we showed that once we reduce the amount of virus in patients, they very quickly started to feel better," DeVincenzo said.

Drug Gives 'New Hope' Against Heart Failure, Expert Says
In a head-to-head comparison, an experimental drug was more effective than standard treatment at preventing deaths and hospitalizations in heart failure patients.
According to the study authors, the trial was stopped early because of the marked benefit of the new drug, dubbed LCZ696. [LCZ696 is an investigational combination drug consisting of two antihypertensives (blood pressure lowering drugs), valsartan (left below) and AHU-377 (right below), in a 1:1 mixture. It is being developed by Novartis. The combination is often described as a dual-acting angiotensin receptor-neprilysin inhibitor (ARNi)]
In the trial, 26.5 percent of those getting the standard medication, enalapril (Vasotec), either died or were hospitalized due to heart failure, compared with 21.8 percent of those on the new drug. Enalapril belongs to a class of blood pressure-lowering medications known as ACE inhibitors.
"LCZ696 could become the new gold standard, replacing ACE inhibitors," said lead researcher Dr. John McMurray, a professor of cardiology at the British Heart Foundation Cardiovascular Research Center at the University of Glasgow, in Scotland.
LCZ696 combines two blood pressure drugs -- an angiotensin II receptor blocker (ARB) and the neprilysin inhibitor known as sacubitril.
"We found that LCZ696 was superior to the gold-standard ACE inhibitor for heart failure -- an ACE inhibitor being the absolute cornerstone of treatment for this problem," he said.
Not only did LCZ696 beat enalapril, but it did that even when added to other treatments, McMurray noted.
"The new treatment was very well tolerated, with no significant safety concerns," he added.

Synthesis produces new fungus-derived antibiotic
A fortuitous collaboration has led to the total synthesis of a recently discovered natural antibiotic. The laboratory recreation of a fungus-derived antibiotic, viridicatumtoxin B, may someday help bolster the fight against bacteria that evolve resistance to treatments in hospitals and clinics around the world.
As part of the process, Rice organic chemist K.C. Nicolaou and structural biologist Yousif Shamoo and their colleagues created and tested a number of variants of viridicatumtoxin B that could lead to the simplified synthesis of a new generation of more effective antibiotics.
The work reported this month in the Journal of the American Chemical Society (JACS) focused on a tetracycline discovered in 2008 by scientists who isolated small amounts from penicillium fungi. The yield wasn't nearly enough for extensive testing, but it provided a basis for the discoverers to analyze its structure through magnetic resonance imaging, Nicolaou said.
"We're inspired by molecules that are biologically active and have the potential to become medicines one day," he said.
The new discovery belongs to a class of antibiotics known as tetracyclines for their distinctive molecular structure. They proved potent in initial tests on
Gram-positive bacteria, so named for a staining technique to mark bacteria that are more susceptible to antibiotics than their Gram-negative counterparts.

"Tetracyclines are widespread antibiotics today, but bacteria are building resistance to a lot of them," Nicolaou said. "This new tetracycline is not plentiful in nature, so the only way we can make it available to study by biologists for its potential in medicine is to synthesize it in the laboratory."

In
the study, all 18 monkeys exposed to a lethal dose of Ebola virus
survived when given the drug, known as ZMapp, even when the treatment
was started five days after infection, when the animals were already
sick.
Moreover,
the monkeys’ symptoms, such as excessive bleeding, rashes and signs of
liver toxicity, eventually disappeared. By contrast, all three monkeys
in the control group died.
Experts
said these were the best monkey results reported to date for any Ebola

Researchers uncover how malaria parasite becomes resistant to fosmidomycin drug
Researchers have uncovered a way the malaria parasite becomes resistant to an investigational drug. The discovery, at Washington University School of Medicine in St. Louis, also is relevant for other infectious diseases including bacterial infections and tuberculosis.
The study appears July 24 in Nature Communications.
Many organisms, including the parasite that causes malaria, make a class of molecules called isoprenoids, which play multiple roles in keeping organisms healthy, whether plants, animals or bacteria. In malaria, the investigational drug fosmidomycin blocks isoprenoid synthesis, killing the parasite. But over time the drug often becomes less effective.
"In trials testing fosmidomycin, the malaria parasite returned in more than half the children by the end of the study," said senior author Audrey R. Odom, MD, PhD, assistant professor of pediatrics. "We wanted to know how the parasite is getting around the drug. How can it manage to live even though the drug is suppressing these compounds that are necessary for life?"
Fosmidomycin, an antibiotic, is being evaluated against malaria in phase 3 clinical trials in combination with other antimalarial drugs.
Using next-generation sequencing technology, the research team compared the genetics of malaria parasites that responded to the drug to the genetics of malaria parasites that were resistant to it. With this approach, Odom and her colleagues found mutations in a gene called PfHAD1. With dysfunctional PfHAD1, malaria is resistant to fosmidomycin.
"The PfHAD1 protein is completely unstudied," Odom said. "It's a member of a larger family of proteins, and there are almost no biological functions assigned to them."
In malaria parasites, Odom's team showed that the PfHAD1 protein normally slows down the synthesis of isoprenoids. In other words, when present, PfHAD1 is doing the same job as the drug, slowing isoprenoid manufacturing. Since isoprenoids are necessary for life, it's not clear why the organism would purposefully slow down isoprenoid production.

Antifungal drug resistance evoked through RNAi-dependent epimutations
Microorganisms like bacteria and fungi can evade treatment by acquiring mutations in the genes targeted by antibiotics or antifungal drugs. These permanent mutations were once thought to be the only way for drug-resistant strains to evolve. Now a new study has shown that microorganisms can use a temporary silencing of drug targets -- known as epimutations -- to gain the benefits of drug resistance without the commitment.
Though the new mechanism was discovered in a fungus called Mucor circinelloides, it is likely to be employed by other fungi as well as bacteria, viruses and other organisms to withstand treatment with various drugs. The finding appears July 27, 2014, in Nature.
"This mechanism gives the organism more flexibility," said Joseph Heitman, M.D., Ph.D., senior study author and professor and chair of molecular genetics and microbiology at Duke University School of Medicine. "A classic, Mendelian mutation is a more permanent binding decision, like a traditional marriage. These epimutations are reversible, more akin to moving in together. If conditions change, it is easier to revert to the way things were."
The epimutations are so transient, in fact, that the researchers almost disregarded them. Cecelia Wall, a graduate student in Drs. Heitman and Maria Cardenas' labs, had been looking for mutations that would make the human fungal pathogen M. circinelloides resistant to the antifungal drug FK506 (also known as tacrolimus). This pathogen causes the rare but lethal fungal infection mucormycosis, an emerging infectious disease that predominantly affects individuals with weakened immune systems.

Protein once seen as promising anti-cancer compound helps to stabilize neural circuits
Researchers at UC San Francisco (UCSF) have discovered that endostatin, a protein that once aroused intense interest as a possible cancer treatment, plays a key role in the stable functioning of the nervous system.
A substance that occurs naturally in the body, endostatin potently blocks the formation of new blood vessels. In studies in mice in the late 1990s, endostatin treatment virtually eliminated cancer by shutting down the blood supply to tumors, but subsequent human clinical trials proved disappointing.
"It was a very big surprise" to find that endostatin, through some other mechanism, helps to maintain the proper workings of synapses, the sites where communication between nerve cells takes place, said Graeme W. Davis, PhD, Hertzstein Distinguished Professor of Medicine in the Department of Biochemistry and Biophysics at UCSF and senior author of the new study. "Endostatin was not on our radar."

High-dose fluticasone effective against eosinophilic esophagitis, study shows...
I continuation of y update on Fluticasone..
Results from a clinical trial show that high doses of the corticosteroid fluticasone propionate safely and effectively induce remission in many people with eosinophilic esophagitis (EoE), a chronic inflammatory disease of the esophagus characterized by high levels of white blood cells called eosinophils. However, some trial participants did not respond to fluticasone even after six months of high-dose treatments, providing evidence that certain people with EoE are steroid-resistant. By analyzing gene expression -- the degree to which certain genes are turned on or off -- in esophageal tissues, the scientists identified a cluster of genes that may help predict steroid responsiveness.

Bowel cancer breakthrough may benefit thousands of patients
Researchers at Queen's University have made a significant breakthrough that may benefit
patients with bowel cancer.
patients with bowel cancer.
Dr Sandra van Schaeybroeck and her team have discovered how two genes cause bowel cancer cells to become resistant to treatments used against the disease. The research, which was funded by Cancer Research UK, was published this month in the international journal CellReports.
The activity of the two genes, called MEK and MET, was uncovered when the researchers looked at all the different pathways and interactions taking place in bowel cancer cells.
Dr van Schaeybroeck and her group found that these bowel cancers switch on a survival mechanism when they are treated with drugs that target faulty MEK genes. But when the researchers added drugs that also block the MET gene, the bowel cancer cells died.
The team are now testing a new approach to target these two genes in the most aggressive forms of bowel cancer in a European Commission funded clinical trial that is being led by Dr van Schaeybroeck.

New combination drug controls tumor growth, metastasis in mice...
Researchers at UC Davis, University of Massachusetts and Harvard Medical School have
created a combination drug that controls both tumor growth and metastasis. By combining a COX-2 inhibitor, similar to Celebrex, and an epoxide hydrolase (sEH) inhibitor, the drug controls angiogenesis (blood vessel formation), limiting a tumor's ability to grow and spread. The study appears today in the journal Proceedings of the National Academy of Sciences.
created a combination drug that controls both tumor growth and metastasis. By combining a COX-2 inhibitor, similar to Celebrex, and an epoxide hydrolase (sEH) inhibitor, the drug controls angiogenesis (blood vessel formation), limiting a tumor's ability to grow and spread. The study appears today in the journal Proceedings of the National Academy of Sciences.
"We've been studying the effects of COX and sEH inhibitors, both by themselves and in combination, for several years," said senior author and UC Davis Distinguished Professor Bruce Hammock. "We were surprised to find that the dual inhibitor was more active than higher doses of each compound, either individually or together. By combining the two molecules into one we got much greater potency against several diseases and completely unique effects in terms of blocking tumor growth and metastasis."
Both COX and sEH enzymes control lipid signaling, which has long been associated with inflammation, cell migration, proliferation, hypertension and other processes. COX inhibitors block production of inflammatory and pain-inducing lipids, while sEH inhibitors preserve anti-hypertensive, anti-inflammatory and analgesic compounds. Separate COX and sEH inhibitors were previously found to work together in reducing inflammation and neuropathic pain.
After testing individual COX-2 and sEH inhibitors, the team synthesized the drug (PTUTB), the first combined COX-2/sEH inhibitor. They then tested the dual inhibitor against human lung and breast tumors, both in vitro and in mice. They found that PTUTB blocked angiogenesis, inhibiting the proliferation of endothelial cells, which are critical to blood vessel formation. This in turn limited tumor growth and metastasis, reducing lung and breast tumor growth by 70 to 83 percent.
In breast and lung cancers, the dual inhibitor blocked angiogenesis, which blocked the growth of solid tumors," said Hammock. "This represents a new mechanism to control blood vessel and tumor growth."
Robert Weiss, a co-author and professor of nephrology at UC Davis, added that the combination drug achieved the results with minimal side effects and no cardiovascular or gastrointestinal effects.
"This is particularly important when administering COX-2 inhibitors, which have well-known cardiovascular risks," he said. "However, the added sEH inhibitor appears to block COX-2's side effects."
The research was initiated by first author Guodong Zhang when he was a postdoctoral fellow in the Hammock laboratory. Zhang previously demonstrated that sEH inhibitors improve the power of omega-3 fatty acid (fish oil) diets to reduce tumor growth and metastasis, and implicated epoxides of the dietary supplement DHA as the causative agent.

Liver Cancer Drug Fails to Live Up to Early Promise...
In continuation of my update on everolimus
Although it looked promising in early studies, the drug everolimus didn't improve survival for people with advanced liver cancer in its latest trial, a new study found.
The findings from the phase 3 clinical trial are disappointing because earlier research suggested that everolimus (Afinitor) prevented tumor progression and improved survival for in advanced liver cancer. Normally, these patients can expect a median overall survival of less than one year.
The only drug currently shown to significantly improve survival of advanced liver cancer patients is sorafenib (Nexavar). But that drug's benefits are temporary and the cancer eventually progresses, according to background information in the new study.
The current study included 546 adults with advanced liver cancer whose disease progressed during or after treatment with sorafenib, or who could not take sorafenib. The patients were divided into two groups, with 362 given everolimus and 184 given a placebo.

New Inhaled Drug Shows Promise Against Asthma, Allergies...........
A new inhaled medication has the potential to treat mild asthma and allergies by interrupting the production of an immune system protein that triggers allergic reactions, a new study reports.
The drug, quilizumab, targets the blood cells that produce a protein called immunoglobulin type E (IgE), that serves a key role in allergies.
Quilizumab lowered total levels of IgE in the blood of people with allergies and mild asthma, and kept them low for a month, researchers report in the July 2 issue of the journal Science Translational Medicine.
"The subjects who received the drug not only had a reduction in their total IgE level, it also seemed to block production of new IgE in response to the allergen they inhaled," said study co-author Dr. Jeffrey Harris, principal medical director of immunology, tissue growth and repair for the drug manufacturer Genentech, which produces quilizumab and funded the study.
However, one expert noted that the drug has yet to prove itself against moderate to severe asthma.

Breast Cancer Drug May Help Women Fight a Leading Cause of Infertility: Study
Women with polycystic ovary syndrome have a better chance of getting pregnant if they take a breast cancer drug instead of the currently preferred medication, a new study suggests.
Polycystic ovary syndrome -- the most common cause of female infertility in the United States -- causes higher than normal levels of the male hormone androgen, infrequent periods and small cysts on the ovaries. It affects 5 to 10 percent of reproductive-age women, according to background information in the study.
Currently, doctors typically prescribe clomiphine (Clomid) to boost fertility for women with polycystic ovary syndrome. However, this new study suggests the drug letrozole (Femara) results in better ovulation, conception and birth rates.
"We found a simple and comparatively safe and vastly more effective treatment for [polycystic ovary syndrome]," said lead researcher Dr. Richard Legro, a professor of obstetrics and gynecology at Penn State University's College of Medicine in Hershey, Penn.
Clomiphine, which works by stimulating ovulation, has been the standard treatment for years, but has a high rate of multiple births, Legro said.
Letrozole, a treatment for breast cancer in postmenopausal women, works by blocking estrogen production, tricking the ovaries into producing more of the hormone, he explained.
The new study, funded by the U.S. National Institutes of Health, was published July 10 in the New England Journal of Medicine.

First drug candidate from NIH program acquired by biopharmaceutical company
A drug candidate developed by researchers at the NIH’s National Center for Advancing Translational Sciences (NCATS) and its collaborators to treat sickle cell disease has been acquired by Baxter International’s BioScience business. The drug candidate, Aes-103, is the first specifically developed to target the underlying molecular mechanism of sickle cell disease. Baxter now will advance the clinical development activities required for regulatory approval and commercialization.
Sickle cell disease is a genetic blood disorder that affects millions worldwide, including approximately 100,000 people in the United States — among them, 1 in 500 African-Americans.
This is the first time a company has acquired a drug candidate developed with NCATS’ Therapeutics for Rare and Neglected Diseases (TRND) program resources. Baxter International recently acquired AesRx, LLC, Newton, Massachusetts — the TRND program collaborator — including Aes-103. TRND and AesRx researchers worked together to develop Aes-103 through a Phase II clinical trial to evaluate safety and effectiveness. The trial data indicated that Aes-103 significantly reduced patients’ pain.
“This is a wonderful example of why NCATS was created,” said NIH Director Francis S. Collins, M.D., Ph.D. “The progress made thus far in the development of Aes-103 demonstrates NCATS’ catalytic role in bringing together the necessary players, whether academic, nonprofit or industry, to overcome obstacles to translation and advance badly needed treatments to patients.”

A new drug holds promise as a safe and effective treatment for constipation caused by prescription narcotic painkillers, new research states.
Constipation is a common side effect experienced by patients taking these powerful medications for chronic pain. When laxatives failed to provide relief, two phase 3 trials found the once-daily drug naloxegol could help.
"The studies showed rapid and sustained improvement for these patients, without compromising their pain management," study author Dr. William Chey, a gastroenterologist and professor of internal medicine at the University of Michigan Health System, said in a university news release.
The U.S. Food and Drug Administration, as well as health agencies in Canada and Europe, are reviewing the drug for possible approval.
Naloxegol (structure) was specifically designed to treat constipation caused by the narcotic painkillers that are often used to treat chronic health issues, such as osteoarthritis and back pain. These medications ease patients' pain by binding to certain receptors in the brain, but they also bind to receptors in the bowel, which raises the risk of constipation.
Naloxegol works by preventing the painkillers from binding to receptors in the bowel, but not the brain, according to the news release.
One of the new studies involved 652 people. The other study included 700 participants. The patients were randomly assigned to receive one 12.5 milligram (mg) or one 25 mg dose of naloxegol daily, or an inactive placebo.
