Azamulin

Azamulin is a selective, irreversible inhibitor of cytochrome P450 (CYP) 3A isoforms (IC50 values range from 26 to 240 nM for CYP3A4 and CYP3A4/5 from different sources). It is at least 50-fold less potent against CYP2J2 and 100-fold less effective against all other CYP isoforms. Azamulin potently blocks the hydroxylation of testosterone and midazolam by CYP3A4.Formal Name: (3aS,4R,5S,6R,8R,9R,9aR,10R)-6-ethyldecahydro-5-hydroxy-4,6,9,10-tetramethyl-1-oxo-3a,9-propano-3aH-cyclopentacycloocten-8-yl ester 2-[(3-amino-1H-1,2,4-triazol-5-yl)thio]-acetic acid.
