Michael Zasloff
Michael Alan Zasloff (born February 7, 1946) is an American physician–scientist, immunologist, and biotechnology entrepreneur. He is best known for discovering antimicrobial peptides in amphibians, particularly the magainins, and for developing the shark-derived compound squalamine as a potential therapy for viral infections and Parkinson's disease. Zasloff is Professor of Pediatrics and Surgery at Georgetown University School of Medicine and serves as Scientific Director of the MedStar Georgetown Transplant Institute .
Zasloff was born in New York City to a dentist and an artist, and grew up on Manhattan’s West Side. He attended the Bronx High School of Science, then earned a B.A. in chemistry at Columbia College (New York) in 1967, and both an M.D. and Ph.D. in biochemistry from the New York University Grossman School of Medicine in 1973, studying under Nobel laureate Severo Ochoa.
After his pediatric residency at Boston Children's Hospital, Zasloff joined the National Institutes of Health in 1975. During the 1980s he served as Chief of the Human Genetics Branch at the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).
In 1988, Zasloff joined the University of Pennsylvania School of Medicine as the Charles E. H. Upham Professor of Pediatrics and Genetics and became Director of the Division of Human Genetics at the Children’s Hospital of Philadelphia.
In 1988, Zasloff founded Magainin Pharmaceuticals to develop peptide-based therapeutics. In July 1992, Zasloff left Penn to join Magainin full time as Executive Vice President and President of the Magainin Research Institute, the company’s basic research division. From July 1996 through November 2000 he served as Vice Chairman of the board. In 1993, Magainin Pharmaceuticals entered a 30-month collaboration with Sandoz to co-develop cancer-fighting drugs based on magainins, with funding primarily provided by Sandoz and joint ownership of any resulting compounds.
In 2002, Zasloff joined Georgetown University Medical Center as Dean of Research and Translational Science, tasked with integrating Georgetown’s basic science programs with the clinical environment of the medical center. Since 2004 he has been engaged in studies of innate immunity within the MedStar Georgetown Transplant Institute and serves as its Scientific Director. In 2012 he received an honorary Doctor of Science from Georgetown and delivered the School of Medicine’s commencement address.
In 2016, Zasloff co-founded Enterin Inc. with neurologist Denise Barbut and chemist Bill Kinney to develop therapies targeting the gut–brain axis in neurodegenerative disease. The company’s lead compound, ENT-01, is an orally administered derivative of squalamine designed to displace aggregated alpha-synuclein in enteric neurons. Clinical trials have shown improvements in bowel function and neuropsychiatric symptoms in Parkinson's disease patients.
In the mid-1980s, while working with African clawed frogs (Xenopus laevis), Zasloff discovered natural antibiotic peptides, which he named magainins (from the Hebrew word for "shield"). They proved active against bacteria, fungi, protozoa, and some viruses. A 1988 Washington Post profile described them as “a remarkable family of natural antibiotics.”
