oligomycin A

CHEBI:28285 ·resolve ·ANTIFUNGAL ·EXACT SEEDED

An oligomycin with formula C45H74011. An inhibitor of mitochondrial F1FO ATP synthase that induces apoptosis in a variety of cell types and exhibits antifungal, antitumour, and nematicidal activities, but its clinical application has been limited by poor solubility in water and other biocompatible solvents. — ChEBI

Mechanism summary

Mode of action: ENERGY_METABOLISM_INHIBITION host shared target — Assigned from ChEBI role CHEBI:20854 (ATP synthase inhibitor), CHEBI:73214 (EC 3.6.3.14 (H+-transporting two-sector ATPase) 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.
