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.
