Hymeglusin (29066-42-0) is an inhibitor of eukaryotic mevalonate biosynthesis via inhibition of HMG-CoA synthase, IC50=0.12 μM.1 Acts via covalent modification of the active site Cys129.1,2 Inhibits cholesterol biosynthesis in rats (45% at 25 mg/Kg).1 Also inhibits bacterial HMG-CoA synthase.3 Inhibits dengue virus replication.4
