Paul Zamecnik

Paul Charles Zamecnik (November 22, 1912 – October 27, 2009) was an American scientist who played a central role in the early history of molecular biology. He was a professor of medicine at Harvard Medical School and a senior scientist at Massachusetts General Hospital.

Zamecnik pioneered the in vitro synthesis of proteins and helped elucidate the way cells generate proteins. With Mahlon Hoagland he co-discovered transfer RNA (tRNA). Through his later work, he is credited as the inventor of antisense therapeutics.

Throughout his career, Zamecnik earned over a dozen US patents for his therapeutic techniques. Up until his death in 2009 he maintained a lab at MGH where he studied the application of synthetic oligonucleotides (antisense hybrids) for chemotherapeutic treatment of drug resistant and XDR tuberculosis in his later years.
