Supervision of Chinese-Made Drug Substances by Philippe André
Why source drug substances from China?
Large markets, economies of scale and cheaper labor;An industrial ecosystem supplying raw materials and equipment;Developed infrastructure and industry friendly policies;About 5,000 manufacturers;
Thousands of chemists and students across China looking for novel synthesis routes for generic drug substances and intermediates.

Pharmaceutical Industry In Global Market: Issues To Be Handled For Better Growth
In the global market, the position of the pharmaceutical industry is not parallel as compared to other information and technology based industries.
Among the Leading industries, the pharmaceutical industry lacks behind in the growth rate as far as innovative research, capital investment and
government regulations are concern. Most of the countries simply depends on bulk production of the generic drugs and not focused on core research. In
comparison with the growth rate of the electronic and IT industry stands first where as the pharmaceutical comes at the 9th position.

Vivus has presented data on its already-approved but not-yet-marketed erectile dysfunction drug Stendra which shows that the treatment is effective for sexual activity within 15 minutes.
Stendra (avanafil) was given the green light by the US Food and Drug Administration over a year ago, but there has been no launch yet as Vivus has been seeking a partner. The latest data should be attractive to potential suitors and could help Stendra take on other phosphodiesterase type 5 (PDE5) inhibitors, notably Pfizer’s Viagra (sildenafil) but also Eli Lilly’s Cialis (tadalafil) and Bayer’s Levitra (vardenafil).

In pyrimidine, if the 2 – and 4 – positions are active simultaneously the same leaving group in the case, SNAr reaction occurs preferentially at 4 – position, but does not guarantee the 2 – side reaction does not occur. Here is an activity of the poor leaving group sulfide spans 2 – bit, and a good leaving group active chlorine occupy four – position, thus ensuring a high regioselectivity of the reaction. 4 – position after completion of the reaction, then the 2 – position of the group activation, where sulfide sulfoxide better than the leaving group.

A vaccine against a cervical cancer virus has cut infections in teen girls by half, according to a study released. The study confirms research done before the HPV vaccine came on the market in 2006. But this is the first evidence of how well it works now that it is in general use.

Amgen has the second deepest pipeline of drugs of the three large cap biotechs. According to Amgen, they have 45 drugs in development from Phase 1 to Phase 3. Conversely, Gilead has 32 drugs in development and Pfizer has 64. Meanwhile, Gilead only has 8 drugs in Phase 3, Pfizer has 25, and Amgen has 14. 7 of those Phase 3 drugs are focused on cancer treatments for Amgen, more than either Pfizer or Gilead. Keep in mind that 12.4 million people learn they have cancer each year, while 7.6 million people lose that battle each year. The CDC predicts that the global number of cancer related deaths will increase by 80% by 2030. It doesn’t take a rocket scientist to know that cancer treating drugs presents the largest opportunity for any drug maker considering those statistics. Amgen has the inside track versus Gilead and Pfizer as far as quantity of drugs in late stage development.

Tocilizumab Impresses in Polyarticular Juvenile Arthritis
Medscape
MADRID, Spain — Children with polyarticular juvenile idiopathic arthritis treated with tocilizumab (Actemra, Genentech) achieved high response rates with sustained improvement in the phase 3 CHERISH trial.
The results prompted the US Food and Drug Administration toapprove tocilizumab for this indication. The drug is already approved for systemic juvenile idiopathic arthritis and for adults with moderate to severe rheumatoid arthritis.

Tocilizumab (INN, or atlizumab, developed by Hoffmann–La Roche and Chugai and sold under the trade names Actemra and RoActemra) is an immunosuppressive drug, mainly for the treatment of rheumatoid arthritis (RA) and systemic juvenile idiopathic arthritis, a severe form of RA in children. It is a humanized monoclonal antibody against the interleukin-6 receptor (IL-6R). Interleukin 6 (IL-6) is a cytokine that plays an important role in immune response and is implicated in the pathogenesis of many diseases, such asautoimmune diseases, multiple myeloma and prostate cancer.
Let’s Set a Global Drug Quality Benchmark by Kiran M Shaw, Biocon
With Indian-made generics accounting for a US market share of over 25 per cent, it is not surprising that it is gaining significant mindshare of the Food and Drug Administration ( FDA). The spate of quality issues with leading Indian pharmaceutical companies in the past couple of years however should not be viewed in isolation. Big Pharma in the West, too, has been facing increasing flak from the FDA and other regulators over good manufacturing practice ( GMP) violations. High profile names like J& J, Genzyme (Sanofi), GSK, Sandoz, Watson, Teva and many others have encountered their share of quality problems and have been served with ‘warning letters’ from FDA

Adamas claims success with new and improved Parkinson’s drug
Amantadine (trade name Symmetrel, by Endo Pharmaceuticals) is a drug that has US Food and Drug Administration approval for use both as an antiviral and an antiparkinsonian drug. It is the organic compound 1-adamantylamine or 1-aminoadamantane, meaning it consists of an adamantane backbone that has an amino group substituted at one of the four methyne positions. Rimantadine is a closely related derivative of adamantane with similar biological properties.
Apart from medical uses, this compound is useful as a building block, allowing the insertion of an adamantyl group.
According to the US Centers for Disease Control and Prevention, 100% of seasonal H3N2 and 2009 pandemic flu samples tested have shown resistance to adamantanes, and amantadine is no longer recommended for treatment of influenza in the United States. Additionally, its effectiveness as an antiparkinsonian drug is undetermined, with a 2003 Cochrane Review concluding that there was insufficient evidence in support or against its efficacy and safety.
Synthesis
Amantadine may be prepared by reacting adamantane with bromine or nitric acid to give the bromide or nitroester at position one. Reaction of either compound with acetonitrile affords the acetamide, which is hydrolyzed to give 1-adamantylamine:
