Isotretinoin
Isotretinoin is a teratogen; there is about a 20–35% risk for congenital defects in infants exposed to the drug "in utero", and about 30–60% of children exposed to isotretinoin prenatally have been reported to show neurocognitive impairment. Because of this, there are strict controls on prescribing isotretinoin to women who may become pregnant and women who become pregnant while taking isotretinoin are strongly advised to terminate their pregnancies.
Raymond J. Deshaies
Drug development: Deshaies, in collaboration with Craig Crews (Yale), conceived the idea of using heterobifunctional small molecules, referred to as PROTACs, to tether cellular proteins to a ubiquitin ligase, resulting in ubiquitination and degradation of the tethered protein. This concept now underlies the biotechnology companies Arvinas and C4 Therapeutics. The Deshaies group also identified small molecules that inhibit targeting of substrates to the proteasome and removal of ubiquitin chains from substrates by Rpn11. In addition, they discovered (in collaboration with Dr. Hugh Rosen of Scripps and Frank Schoenen of University of Kansas) the p97 inhibitors DBeQ and ML240. ML240 served as the basis for the development of CB-5083, which entered human clinical trials in 2014.
