CHEBI:85979 ·resolve ·ANTIFUNGAL ·EXACT SEEDED

A 1,3-thiazole that is butan-2-ol which is substituted at positions 1, 2, and 3 by 1,2,4-triazol-1-yl, 2,5-difluorophenyl, and 4-(p-cyanophenyl)-1,3-thiazol-2-yl groups, respectively. It is an antifungal drug used for the treatment of invasive aspergillosis and invasive mucormycosis. — ChEBI

Mechanism summary

Mode of action
ERGOSTEROL_PATHWAY_INHIBITION host shared target — Assigned from ChEBI role CHEBI:75282 (ergosterol biosynthesis inhibitor), CHEBI:77884 (EC 1.14.13.70 (sterol 14α-demethylase) inhibitor). ChEBI asserts the role on the compound. The target it names is one the host has too, so the mechanism is true but is not evidence of selectivity — see mode_of_action_target_scope. Not a curator's mechanistic review.
