Roles Classification
Chemical Role(s): Bronsted acid
A molecular entity capable of donating a hydron to an acceptor (Bronsted base).
(via oxoacid )
Biological Role(s): antimetabolite
A substance which is structurally similar to a metabolite but which competes with it or replaces it, and so prevents or reduces its normal utilization.
EC 2.1.1.45 (thymidylate synthase) inhibitor
An EC 2.1.1.* (methyltransferases) inhibitor that interferes with the action of thymidylate synthase (EC 2.1.1.45).
EC 1.5.1.3 (dihydrofolate reductase) inhibitor
An EC 1.5.1.* (oxidoreductase acting on donor CH-NH group, NAD+ or NADP+ as acceptor) inhibitor that interferes with the action of dihydrofolate reductase (EC 1.5.1.3).
EC 2.1.2.2 (phosphoribosylglycinamide formyltransferase) inhibitor
An EC 2.1.2.* (hydroxymethyl-, formyl- and related transferases) inhibitor that interferes with the action of phosphoribosylglycinamide formyltransferase (EC 2.1.2.2).
Application(s): antineoplastic agent
A substance that inhibits or prevents the proliferation of neoplasms.
