Description

SYC-435 : A cyclic hydroxamic acid that is 1-hydroxypyridin-2(1H)-one in which the hydrogens at positions 4 and 6 are substituted by methyl and benzyl groups, respectively. It is a potent inhibitor of mutant isocitrate dehydrogenase 1 (Ki values of 190 nM against R132H mutant and 120 nM against R132C mutant).
