Today is the 70th death anniv of Yellapragada Subbarao.

Subbarao discovered the function of ATP as an energy source in the cell, developed methotrexate for the treatment of cancer and discovered a broad spectrum antibiotic Auromycin and Tetracycline.

"His elder brother & younger brother both died due to tropical sprue in span of 8 days, so he discovered folic acid as a cure for tropical sprue. He discovered methotrexate, a chemotherapy drug still used today and also used for rheumatoid arthritis, and diethyl carbamazine(DEC)"

"Most of his career was spent in the United States. Despite his isolation of ATP, Subbarao did not gain tenure at Harvard... though he would lead some of America's most important medical research during World War II."

"Subbarao's colleague, George Hitchings said, "Some of the nucleotides isolated by Subbarao had to be rediscovered years later by other workers because Fiske, apparently out of jealousy, did not let Subbarao's contributions see the light of the day."

"Writing in the April 1950 issue of Argosy, Doron K. Antrim observed, "You've probably never heard of Dr. Yellapragada Subbarao. Yet because he lived, you may be alive and are well today. Because he lived, you may live longer.""
