Mechanism summary

Mode of action: NUCLEIC_ACID_SYNTHESIS_INHIBITION host shared target — Assigned from ChEBI role CHEBI:50750 (EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] 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.
