Biological Activity

[Description]:

Troleandomycin (Triacetyloleandomycin), a macrolide acrolide antibiotic, is a selective CYP3A inhibitor. Troleandomycin is an oral corticosteroid for asthma study[1][2][3].

Signaling Pathways >> Metabolic Enzyme/Protease >> Cytochrome P450
Research Areas >> Inflammation/Immunology

[In Vitro]

Troleandomycin markedly inhibits 6β-hydroxylation of testosterone, 25- and 26-hydroxylations of 5β-cholestane-3α,7α,12α-triol and 23R-, 24R-, 24S-, and 27-hydroxylations of 5β-cholestane-3α,7α,12α,25-tetrol in both recombinant CYP3A4 and microsomes, but IC50 values for microsomes are somewhat higher than those for recombinant CYP3A4[1].

[In Vivo]

Troleandomycin markedly suppresses these microsomal side chain hydroxylations in both mouse and human livers in a dose-dependent manner[2]. Animal Model: SD female rats[1]. Dosage: 500 mg/kg. Administration: A single oral dose. Result: Markedly elevated the Cmax and AUC0-6 of simvastatin by 9.5- and 10.2-fold, respectively.
