Mechanism summary
- Mode of action
- NUCLEIC_ACID_SYNTHESIS_INHIBITION host shared target — Assigned from ChEBI role CHEBI:59517 (DNA synthesis 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.
