Ranbaxy Marks World Malaria Day by Unveiling "Indigenously" Developed Anti-Malaria Drug

Ranbaxy Marks World Malaria Day by Unveiling "Indigenously" Developed Anti-Malaria Drug:

Indian pharmaceutical giant Ranbaxy announced at a conference in New Delhi that it has developed a new "indigenous" anti-malaria drug.

The new drug, called Synriam, which is effective against the deadliest malaria microbe, Plasmodium Falciparum, would be a boon for millions of malaria patients around the globe, said Ranbaxy chief executive and managing director Arun Sawhney.

New drug to tackle body fat problems

Leptin regulates energy homeostasis, fertility, and the immune system, making it an important drug target. However, due to a complete lack of structural data for the obesity receptor (ObR), leptin's mechanism of receptor activation remains poorly understood. Researchers have crystallized the Fab fragment of a leptin-blocking monoclonal antibody (9F8), both in its uncomplexed state and bound to the leptin-binding domain (LBD) of human ObR. They describe the structure of the LBD-9F8 Fab complex and the conformational changes in 9F8 associated with LBD binding. A molecular model of the putative leptin-LBD complex reveals that 9F8 Fab blocks leptin binding through only a small (10%) overlap in their binding sites, and that leptin binding is likely to involve an induced fit mechanism. This crystal structure of the leptin-binding domain of the obesity receptor will facilitate the design of therapeutics to modulate leptin signaling.

Pistachio Intake May Endorse a Valuable Gut Environment

Pistachio Intake May Endorse a Valuable Gut Environment: 

Eating pistachios can help adjust levels of potentially valuable bacteria in the gut, a finding that holds promise for supporting digestive health counsels a preliminary 16-person study. The research, presented as an abstract this week at the Experimental Biology conference, is the first study of pistachios and almonds and their modulating role on the gut microbiota composition.

"Gut microbiota, or the microbial environment in the gastrointestinal tract, provides ...

Re: FDA Approves Votrient for Advanced Soft Tissue Sarcoma...

In continuation of my update on Pazopanib..


U.S. Food and Drug Administration, approved Votrient (pazopanib) to treat patients with advanced soft tissue sarcoma who have previously received chemotherapy. Soft tissue sarcoma is a cancer that begins in the muscle, fat, fibrous tissue, and other tissues.

Votrient is a pill that works by interfering with angiogenesis, the growth of new blood vessels needed for solid tumors to grow and survive.


A rare cancer with many subtypes, soft tissue sarcoma occurs in about 10,000 cases annually in the United States. More than 20 subtypes of sarcoma were included in the clinical trial leading to approval of Votrient. The drug is not approved for patients with adipocytic soft tissue sarcoma and gastrointestinal stromal tumors.

"Soft tissue sarcomas are a diverse group of tumors and the approval of Votrient for this general class of tumors is the first in decades," said Richard Pazdur, M.D., director of the Office of Hematology and Oncology Products in the FDA's Center for Drug Evaluation and Research. "Drug development for sarcomas has been especially challenging because of the limited number of patients and multiple subtypes of sarcomas."

The safety and effectiveness of Votrient was evaluated in a single clinical study in 369 patients with advanced soft tissue sarcoma who had received prior chemotherapy. Patients were randomly selected to receive Votrient or a placebo. The study was designed to measure the length of time a patient lived without the cancer progressing (progression-free survival). The disease did not progress for a median of 4.6 months for patients receiving Votrient, compared with 1.6 months for those receiving the placebo.

The most common side effects in Votrient-treated patients were fatigue, diarrhea, nausea, weight loss, high blood pressure, decreased appetite, vomiting, tumor and muscle pain, hair color changes, headache, a distorted sense of taste, shortness of breath, and skin discoloration.

Votrient carries a boxed warning alerting patients and health care professionals to the potential risk of liver damage (hepatotoxicity), which can be fatal. Patients should be monitored for liver function and treatment should be discontinued if liver function declines.

Gabapentin drug helps people to quit cannabis..

We know that, Gabapentin (see structure; brand names Fanatrex, Gabarone, Gralise, Neurontin, Nupentin) is a pharmaceutical drug, specifically a GABA analogue. It was originally developed for the treatment of epilepsy, and currently is also used to relieve neuropathic pain. 

Now Scientists at The Scripps Research Institute have found clinical evidence that the drug gabapentin, currently on the market to treat neuropathic pain and epilepsy, helps people to quit smoking marijuana (cannabis). Unlike traditional addiction treatments, gabapentin targets stress systems in the brain that are activated by drug withdrawal.

In a 12-week trial of 50 treatment-seeking cannabis users, those who took gabapentin used less cannabis, experienced fewer withdrawal symptoms such as sleeplessness, and scored higher on tests of attention, impulse-control, and other cognitive skills, compared to patients who received a placebo. If these results are confirmed by ongoing larger trials, gabapentin could become the first FDA-approved pharmaceutical treatment for cannabis dependence.

"A lot of other drugs have been tested for their ability to decrease cannabis use and withdrawal, but this is the first to show these key effects in a controlled treatment study," said Barbara J. Mason, the Pearson Family Chair and Co-Director of the Pearson Center for Alcoholism and Addiction Research at Scripps Research. "The other nice thing about gabapentin is that it is already widely prescribed, so its safety is less likely to be an issue."

Experts share top 5 springtime fruits and vegetables that fight cancer: The price of springtime fruits and vegetables seems to increase each year. But when buyers break this expense down to cents, they realize stocking up on these cancer-fighting foods still makes economical sense, say experts from The University of Texas MD Anderson Cancer Center.

Consumption of long-chain omega-3 PUFAs lowers risk of colorectal polyps in women: New research finds that omega-3 polyunsaturated fatty acids (PUFAs) found in seafood (long-chain omega-3s) may reduce the risk of precancerous colorectal polyps in women, enhance the muscular benefits of strength training in older women and improve eye health after corneal surgery.

Natural products isolated from marine mollusks and sponges can reverse multidrug resistance in cancer cells

Oceans are a treasure trove of naturally produced chemical compounds with impressive and varied biological activity. One class of these compounds, the lamellarins, has some members that are cytotoxic, while others are able to reverse multidrug resistance in certain cancer cells. These lamellarins (see below structure) act by inhibiting the so-called P-glycoprotein, which enhances transport of anticancer agents out of cancer cells, thus rendering the cells multidrug resistant.

Now researchers lead by Professor Rob Capon, have set out to determine the structures of a variety of lamellarins and correlate them to the activity of the compounds. As they report in Chemistry—An Asian Journal, the activity is not determined by the core structure of the compounds but rather depends on the exact nature of pendant groups adorning the periphery of the molecule. Those compounds in which many hydroxy (OH) groups had been replaced with methoxy (OCH₃) were able to reverse multidrug resistance in human colon cancer cells, while those featuring a large number of hydroxy groups showed higher cytotoxic activity.

Natural products such as the lamellarins are often valued for their cytotoxic properties for use as anticancer drugs. Capon, however, comments, "Our investigation reaffirms the view that non-cytotoxic natural products can exhibit valuable biological properties that allude to both an ecological advantage and a pharmacological potential....
