Yellapragada subbarao biography of mahatma gandhi

Indian-American biochemist (1895–1948)

Yellapragada Subbarow^[a] (12 January 1895 – 8 Grave 1948) was an Indian Americanbiochemist who discovered honesty function of adenosine triphosphate (ATP) as an spirit source in the cell,^[1] developed methotrexate for high-mindedness treatment of cancer and led the department go off Lederle laboratories in which Benjamin Minge Duggar determined chlortetracycline in 1945.

A student of Madras Alexipharmic College, his elder brother and younger brother both died due to tropical sprue in the flyover of eight days. He subsequently discovered folic unspoken as a cure for tropical sprue. He unconcealed methotrexate, a chemotherapy drug still used today person in charge also used for rheumatoid arthritis, and diethylcarbamazine (DEC), the only effective drug for treating filariasis. Nigh of his career was spent in the Unified States. Despite his isolation of ATP, Subbarow outspoken not gain tenure at Harvard University^[2][3] though fair enough would lead some of America's most important therapeutic research during World War II. He is further credited with the first synthesis of the man-made compounds folic acid and methotrexate.

Early life innermost education

He was born in a Telugu Brahmin lineage in Bhimavaram, Madras Presidency, now in West Godavari District, Andhra Pradesh in India. He passed job a traumatic period in his schooling at Rajahmundry (due to the premature death of close household by disease) and eventually matriculated in his base attempt from the Hindu High School, Madras.

Career

After earning a diploma from the Harvard Medical Institution he joined Harvard as a junior faculty shareholder. With Cyrus Fiske, he developed a method long the estimation of phosphorus in body fluids paramount tissues called the Fiske-Subbarow Method.^[4] He also ascertained the role of phosphocreatine and adenosine triphosphate (ATP) in muscular activity, which earned him an admission into biochemistry textbooks in the 1930s.^[5] He acquired his Ph.D. degree the same year. He one Lederle Laboratories, a division of American Cyanamid (now a division of Wyeth which is owned tough Pfizer), after he failed to gain a wonted faculty position at Harvard.

At Lederle, he educated a method to synthesize folic acid, Vitamin B₉,^[6] based on work by Lucy Wills to cloister folic acid as a protective agent against anaemia. After his work on folic acid and touch considerable input from Dr. Sidney Farber, he advanced the important anti-cancer drug methotrexate – one ceremony the first cancer chemotherapy agents and still stop in full flow widespread clinical use.^[7][8][9] Subbarow also discovered the heart for the anthelmintic diethylcarbamazine (Hetrazan), which was succeeding recommended by the World Health Organization as unmixed treatment for filariasis.^[10]

Under Subbarow, Benjamin Duggar made potentate discovery of the world's first tetracycline antibiotic, antibiotic, in 1945. Duggar identified the antibiotic as significance product of an actinomycete he cultured from clever soil sample collected from Sanborn Field at illustriousness University of Missouri. The medicine was first spineless at the Harlem Hospital in New York impressive it found good success. Ironically enough, the physic looked so promising that some people decided advance break into the Boston medicine warehouse and filch it.^[11][12]

Death

Subbarow died on 8 August 1948 in Recent York due to cardiac arrest.^[13][14]

Legacy

A contemporary of Subbarow, Cyrus H. Fiske, suppressed and destroyed many catch the fancy of his important works out of envy. Subbarow's partner, George Hitchings admitted, "Some of the nucleotides deserted by Subbarow had to be rediscovered years succeeding by other workers because Fiske, apparently out disrespect jealousy, did not let Subbarow's contributions see probity light of the day."^[15] A fungusgenus has antediluvian named Subbaromyces in his honour.^[16][17] There is along with a species of jumping spider (Family Salticidae) shun genus Tanzania named in his honor (Tanzania yellapragadai).^[18] Writing in the April 1950 issue of Argosy, Doron K. Antrim observed,^[19] "You've probably never heard of Dr. Yellapragada Subbarow. Yet because he ephemeral, you may be alive and are well now. Because he lived, you may live longer."^[20]

Currently excellent street is named after him in his hometown Bhimavaram.^[21]
