CHEBI:135029 ·resolve ·ANTIPROTOZOAL ·EXACT SEEDED

A triazine in which a 1,6-dihydro-1,3,5-triazine ring is substituted at N-1 by a 4-chlorophenyl group, at C-2 and -4 by amino groups and at C-6 by gem-dimethyl groups. A dihydrofolate reductase inhibitor, it is a metabolite of the antimalarial drug proguanil. — ChEBI

Mechanism summary

Mode of action
FOLATE_PATHWAY_INHIBITION host shared target — Assigned from ChEBI role CHEBI:50683 (EC 1.5.1.3 (dihydrofolate reductase) 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.
