General description

Azamulin isolated from fungus Pleurotus mutilis is a diterpene antibiotic. It is related to pleuromutilin being its synthetic azole derivative.

Application

Azamulin has been used as a selective CYP3A4 inhibitor to pretreat primary hepatocyte cells and in prostate cancer cell lines LNCaP and MDAPCa2b.

Biochem/physiol Actions

Azamulin is a derivative of the antibiotic pleuromutilin. The compound is a very specific inhibitor of the CYP3A family (IC50 = 0.03-0.24 μM). Azamulin is 15 and 13 fold more active against CYP3A4 compared to CYP3A5 or CYP3A7, respectively, and is at least 100 fold selective over other CYP isoforms, with the exception of CYP2J2 (approximately 50-fold).

Azamulin [14-O-(5-(2-amino-1,3,4-triazolyl)thioacetyl)-dihydromutilin] is an azole derivative of the pleuromutilin class of antiinfectives. We tested the inhibition potency of azamulin toward 18 cytochromes P450 using human liver microsomes or microsomes from insect cells expressing single isoforms. In a competitive inhibition model
