In continuation of my update on usefulness of benzodiazepine derivatives

Lundbeck Inc. presented interim data from its long-term, open-label extension study evaluating ONFI™ (clobazam see structure below) CIV for the adjunctive treatment of drop seizures associated with Lennox-Gastaut syndrome (LGS). Company claims that, these interim results support the reductions in drop seizure rates associated with ONFI when used as add-on therapy for adult and pediatric patients, two years of age or older, with a current or previous diagnosis of LGS. ....

Biogen’s Multiple Sclerosis pill succeeds at a late phase clinical trial

Biogen Idec Inc. has reported success in a late stage clinical trial of its oral multiple sclerosis drug BG-12 (see below structure), a competitor's of Teva Pharmaceutical Industries’ Laquinimod. A 240-milligram dose of BG-12 administered two or three times a day significantly reduced the proportion of patients who relapsed by 49% and 50%, respectively, after two years compared with a placebo....

Company adds that, in addition to significantly reducing ARR, BG-12 met all secondary relapse and MRI endpoints for both dose regimens.....

Leafy greens (broccoli and cabbage) protect the gut’s immune system

In continuation of my update on Broccoli and its usefulness 

Research from the Babraham Institute and the Medical Research Council (MRC), were able to prove that leafy greens protect a certain type of immune cell known as intra-epithelial lymphocytes (IELs). IELs play a crucial role in keeping the gut lining healthy and preventing ‘bad’ bacteria from entering the gut while maintaining the balance of ‘good’ bacteria which help us to break down our food. Researchers studied mice fed a diet containing many vitamins and minerals known to be essential for good health, but which lacked vegetables. Over three weeks the mice lost 70 to 80 per cent of IELs.


The research showed for the first time that mice fed a diet low in vegetables rapidly lose these specialised immune cells lining the intestinal tract, but not other immune cells. The team discovered that IELs depend on chemical signals from the digestive breakdown products of a substance called Indole-3-carbinol, high levels of which are found in vegetables like broccoli and cabbage.......

Phase III Trial of Regorafenib in Metastatic Colorectal Cancer Meets Primary Endpoint of Improving Overall Survival...

Bayer HealthCare Pharmaceuticals, announced the results from its Phase III trial evaluating its investigational compound regorafenib (see structure below, BAY 73-4506) for the treatment of patients with metastatic colorectal cancer (mCRC) whose disease has progressed after approved standard therapies: The trial met its primary endpoint of statistically significant improvement in overall survival. 

This is the result of a pre-planned interim analysis conducted by an independent Data Monitoring Committee (DMC) of the CORRECT (Patients with metastatic colorectal cancer treated with regorafenib or placebo after failure of standard t herapy) trial. Per the recommendation of the DMC, the study has been unblinded and patients in the placebo arm will be offered treatment with regorafenib. In this trial, the safety and tolerability of regorafenib were generally as expected.


"These data are significant because they demonstrate that regorafenib increased overall survival in patients with heavily pretreated metastatic colorectal cancer, an area of high unmet medical need," said Kemal Malik .....

Researcher's compound disables bacteria instead of killing them


A microbiologist at the University of Wisconsin-Milwaukee (UWM) has discovered a different approach: Instead of killing the bacteria, why not disarm them, quashing disease without the worry of antibiotic resistance?

Ching-Hong Yang, associate professor of biological sciences, has developed a compound that shuts off the "valve" in a pathogen's DNA that allows it to invade and infect. The research is so promising that two private companies are testing it with an eye toward commercialization.
"Researchers analyzed the genomic defense pathways in plants to identify all the precursors to infection and  used the information to discover a group of novel small molecules that interrupt one channel in the intricate pathway system."..
Yang and collaborator Xin Chen, a professor of chemistry at Changzhou University in China, have tested the compound on two virulent bacteria that affect plants and one that attacks humans. They found it effective against all three and believe the compound can be applied to treatments for plants, animals and people.

WPI Research Shows How Cranberry Juice Fights Bacteria at the Molecular Level


The study tested proanthocyanidins or PACs, a group of flavonoids found in cranberries. Because they were thought to be the ingredient that gives the juice its infection-fighting properties, PACs have been considered a hopeful target for an effective extract. The new WPI report, however, shows that cranberry juice, itself, is far better at preventing biofilm formation, which is the precursor of infection, than PACs alone. The data is reported in the paper "Impact of Cranberry Juice and Proanthocyanidins on the Ability of Escherichia coli to Form Biofilms," which will be published on-line, ahead of print on Oct. 31, 2011, by the journal Food Science and Biotechnology.

New data on novel gene-silencing oligonucleotide technology...

Idera announced new data on its novel gene-silencing oligonucleotide (GSO) technology at the Cell Symposium on Regulatory RNAs in Chicago, IL. In preclinical studies, systemic delivery of GSOs targeted to ApoB or PCSK9 mRNA caused a reduction in the level of the targeted mRNA and associated protein and resulted in a decrease in serum total cholesterol and LDL-cholesterol concentration. ApoB and PCSK9 are two validated targets associated with cardiovascular diseases.

In this study, Idera created 19mer GSOs for apolipoprotein B (ApoB) and proprotein convertase subtilisin/kexin type 9 (PCSK9) mRNA and evaluated their in vivo activity in mice following subcutaneous administration. The data demonstrate that treatment with each GSO led to a significant reduction in the concentration of the target associated mRNAs and protein. The effects were specific, with no significant effects being observed on ABCA1, ABCG1 or LXR mRNA levels. In addition, treatment with GSOs for either ApoB or PCSK9 resulted in a decrease in total serum cholesterol and LDL-cholesterol.

New Alzheimer's Drug Shows Early Promise

An experimental Alzheimer's disease drug, gantenerumab, may help lower levels of amyloid plaque in the brains of people with the disease, an early clinical trial indicates. Researchers claims that, of 16 people with mild-to-moderate Alzheimer's disease, those who received two to seven infusions of the experimental drug every four weeks showed marked reductions in the amount of plaque in their brains via imaging tests that were conducted several months after their treatments.....

Ginger Supplements Might Ease Inflammation Linked to Colon Cancer..

A small, preliminary study finds that ginger root supplements seem to reduce inflammation in the intestines  a potential sign that the pills might reduce the risk of colon cancer. Previous research in animals has suggested that ginger can reduce inflammation but isn't potentially toxic to the stomach like aspirin, Zick noted. And scientists have linked chronic inflammation in the gut to colon cancer, suggesting that easing this inflammation could reduce the risk of the disease.

In the new study, Zick's team randomly assigned 30 people to take pills containing 2 grams of ground ginger root extract or a "dummy" placebo pill each day for 28 days. They measured the level of inflammation in the participants' intestines before and after the test period. The researchers found that the level of inflammation in the subjects who took the ginger pills fell by an average of 28 percent, while staying about the same in those who took the placebo.
