Yellapragada Subbarow (1895–1948)

Born 1895 CE, died 1948 CE.

Yellapragada Subbarao (Telugu: యల్లాప్రగడ సుబ్బారావు, romanized: Yallāpragaḍa Subbārāvu; 12 January 1895 – 8 August 1948) was an Indian American biochemist who discovered the function of adenosine triphosphate (ATP) as an energy source in the cell, developed methotrexate for the treatment of cancer, and led the department at Lederle laboratories in which Benjamin Minge Duggar discovered chlortetracycline in 1945. A student of Madras Medical College, his elder brother and younger brother both died due to tropical sprue in the span of eight days. He subsequently 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 diethylcarbamazine (DEC), the only effective drug for treating filariasis. Most of his career was spent in the United States. Despite his isolation of ATP, Subbaroa did not gain tenure at Harvard University though he would lead some of America's most important medical research during World War II. He is also credited with the first synthesis of the chemical compounds folic acid and methotrexate.
