Ramachandra S. Hosamane (1944-) is a Senior Professor of Organic Chemistry at University of Maryland, Baltimore County. Dr. Hosmane has over 150 peer-reviewed research publications in reputed international journals. He has 4 awarded US patents, three of which have been licensed to industries. His contributions to the field of Organic Chemistry and medicinal chemistry are notable. He has trained well over 100 undergraduate students, 30 graduate students, and 20 postdoctoral fellows and visiting scientists in his laboratory. His current research focus is on drug discovery for dual inhibition of HCV and HIV as well as lung, breast, and prostate cancers.

Early life

Mr. Ram Hosmane was born in Gokarna, Uttar Kannada, India and completed high school from Bhadrakali High School, Gokarna. In 1966, he earned B.Sc Chemistry from Karnataka University, Dharwar, followed by M.Sc. degree in Organic Chemistry from the same institution in 1968.

Career

Mr. Hosmane moved to USA in the early 70's to pursue a doctoral degree in organic synthesis and medicinal chemistry at the University of South Florida, where he earned M.S. (1976) and Ph.D. (1978) degrees. After completing his postdoctoral training (1979-82) at the University of Illinois, Urbana-Champaign, Dr. Hosmane joined UMBC as an Asst. Professor in the year 1982 and was promoted to Associate Professor with academic tenure in the year 1986. He was promoted to the rank of full Professor in the year 1994.

His research work has been supported by ~ 50 grants by Federal & State agencies such as the National Institutes of Health and the [http://www.mips.umd.edu/ Maryland Industrial Partnerships (MIPS)] , and Private Foundations such as the American Heart Association, American Cancer Society, and [http://portal.acs.org/portal/acs/corg/content?_nfpb=true&_pageLabel=PP_TRANSITIONMAIN&node_id=631&use_sec=false&sec_url_var=region1 Petroleum Research Fund] as well as a variety of industrial sources. He has contributed significantly to the Development of Organic and Medicinal Chemistry.

Mr. Hosmane was awarded [http://userpages.umbc.edu/~hosmane/Photo_Album/Maryland_Chemist_Award.html the Maryland Chemist of the Year Award] from American Chemical Society, [http://mdchem.org/ Maryland Division] in 2002. In 2001, he was awarded Outstanding Educator of the Year Award from [http://www.bsos.umd.edu/mahe/ Maryland Association for Higher Education (MAHE)] . Also he was honored as [http://userpages.umbc.edu/~hosmane/pres_res_prof_award.html the University Presidential Research Professor in 1998] . In 1996, he was Outstanding Mentor, [http://portal.acs.org/portal/acs/corg/content?_nfpb=true&_pageLabel=PP_SUPERARTICLE&node_id=1603&use_sec=false&sec_url_var=region1 Project SEED (American Chemical Society)] . In 1999, he was given honorary faculty membership in [http://www.goldenkey.org/GKIHS Golden Key International Honor Society] . He has been a consistent member of the [http://era.nih.gov/roster/NIH Scientific Review Groups] , serving on a wide variety of NIH grant review panels generally referred to as Study Sections. He is also a reviewer for U.S.Food and Drug Administration (FDA)'s intramural scientific programs.

Two major research areas of Dr. Hosmane include blood substitutes based on hemoglobins and the discovery of antiviral and anticancer compounds based on [http://www.freepatentsonline.com/5843912.html ring-expanded nucleoside structures] . The compounds synthesized in his laboratory have shown potent activities against a wide variety of viruses and cancers, including the hepatitis B (HBV) and hepatitis C (HCV) viruses, human immunodeficiency virus (HIV), the West Nile virus (WNV), the Japanese encephalitis virus (JEV), the measles virus, the rhino virus , the Varicella zoster virus (VZV), Epstein-Barr virus, respiratory syncytial virus (RSV), influenza viruses A & B, Herpes Simplex viruses as well as prostate cancer, lung cancer, breast cancer, colon cancer, and leukemia. His current research focus is on drug discovery for dual inhibition of HCV and HIV as well as lung, breast, and prostate cancers.
