SRI-9439

Development stage: Preclinical
Lead developer: Southern Research
Modality: Small Molecules

Overview

SRI-9439 is a potent lipophilic antifolate inhibitor developed by Southern Research Institute. It targets and inhibits human dihydrofolate reductase (hDHFR), forming a ternary complex with NADPH. The drug was initially developed against *Toxoplasma gondii* DHFR-thymidylate synthase, indicating its potential as an anti-infective agent. Its crystal structure in complex with hDHFR and NADPH has been determined at atomic resolution, providing insights into its binding characteristics and inhibitory activity.

Other names: 6-([5-quinolylamino]methyl)-2,4-diamino-5-methylpyrido[2,3-d]pyrimidine

Targets

DHFR (Dihydrofolate reductase)
