Pfizer, Inc. is an American multinational pharmaceutical corporation headquartered in New York City, and with its research headquarters in Groton, Connecticut, United States. It is one of the world's largest pharmaceutical companies by revenues.Pfizer develops and produces medicines and vaccines for a wide range of medical disciplines, including immunology, oncology, cardiology, diabetologyCelebra , an anti-inflammatory drug.Pfizer was founded by cousins Charles Pfizer and Charles F. Erhart in New York City in 1849 as a manufacturer of fine chemicals. Pfizer's discovery of Terramycin in 1950 put it on a path towards becoming a research-based pharmaceutical company. Pfizer has made numerous acquisitions, including Warner–Lambert in 2000, Pharmacia in 2003 and Wyeth in 2009. The Wyeth acquisition was the largest of the three at US$68 billion. Pfizer is listed on the New York Stock Exchange, and its shares have been a component of the Dow Jones Industrial Average since April 2004.In September 2009, Pfizer pleaded guilty to the illegal marketing of the arthritis drug Bextra for uses unapproved by the U.S. Food and Drug Administration , and agreed to a $2.3 billion settlement, the largest health care fraud settlement at that time. Pfizer also paid the U.S. government $1.3 billion in criminal fines related to the "off-label" marketing of Bextra, the largest monetary penalty ever rendered for any crime. Called a repeat offender by prosecutors, this was Pfizer's fourth such settlement with the U.S. Department of Justice in the previous ten years. Wikipedia.

The present invention relates to novel polymorphic forms of 8-fluoro-2-{4-[(methylamino)methyl]phenyf}-1,3,4,5-tetrahydro-6H-azepino(5,4,3-cd]indol-6-one;(I), and to processes for their preparation. Such polymorphic forms may be a component of a pharmaceutical composition and may be used to treat a mammalian disease condition mediated by poly(ADP-ribose) polymerase activity including the disease condition such as cancer.


A procedure to isolate large quantities of capsular polysaccharides (CPS) from culture supernatants as well as bacterial cells of gram-negative arid gram-positive bacteria using base extraction is described. The procedure is simple, rapid, reproducible and applicable to a variety of bacterial species. The method also yields novel CPS characterized by their lack of covalent attachment to extraneous peptidoglycan. Vaccines and methods of immunization against bacterial infection using the CPS obtained by the process of the invention are also disclosed.

Green Chemistry or Sustainable Chemistry is defined by the Environmental Protection Agency as "the design of chemical products that reduce or eliminate the use of hazardous substances" In recent years there is a greater societal expectation that chemists and chemical engineers should produce greener and more sustainable chemical processes and it is likely that this trend will continue to grow over the next few decades. This tutorial review gives information on solvents and solvent selection, basic environmental metrics collection and three industrial case histories. All three case histories involve enzymatic chemistry. Pregabalin (Lyrica®) is produced using a lipase based resolution and is extremely unusual in that all four manufacturing steps to make pregabalin are performed in water. Sitagliptin (Januvia®) uses a transaminase in the final chemical step. Finally a rosuvastatin (Crestor®) intermediate is produced using a deoxy ribose aldolase (DERA) enzyme in which two carbon-carbon bonds and two chiral centres are formed in the same process step. © 2012 The Royal Society of Chemistry.
