Email: drbgopalan@yahoo.co.in

Dr.Balasubramanian Gopalan a Ph.D. in the year 1973 from University of Madras in Synthetic Organic Chemistry and worked as Post Doctoral fellow in Harvard University with Nobel laurite E.J.Corey and then switched over to the industry and joined Syntex Research Inc., California and Bristol-Myers Squibb in Newjersey, USA.

He returned to India in the year 1982 and headed drug discovery division of Boots Pharmaceuticals Ltd., Sun Pharma Advanced Research Centre, Glaxo Ltd., Glenmark Research Centre, Matrix Laboratories and finally join as Executive Director and Chief of Orchid Chemicals & Pharmaceuticals in the year 2008.

His achievements include discoveries of many new drugs that are in Phase-2 and Phase-3 clinical trial. Many of these discoveries such as Oglemilast (a novel PDE IV inhibitor) was out-licensed to Forest Laboratories, USA for US$190 million over a period of five years & also to Teijin of Japan for US$53 million.

Other of his drug melogliptin a new DPP4 for type 2 diabetes was out-licensed to Merck Germany for US$231 million.

He has been a visiting fellow and elected fellow of many academics and universities to his credit he has 50 international patents.

He shares his expertise by training local talents in drug discovery research from Orchid chemical & Pharmaceuticals Ltd., OMR, Chennai.

Research Interests

The main research interest of the Prunet group is the synthesis of biologically active natural products, such as taxol, a powerful antitumor agent, or dolabelide C and hexacyclinic acid, molecules with cytotoxic activity. In our approaches towards the target molecules, we uncover problems that cannot be easily solved by known reactions, and to overcome these difficulties we try to develop new methodologies that can also be applied to other syntheses.
