Description

2,4-Dichloropyrido[3,4-d]pyrimidine (908240-50-6) video

Dihydrofolate reductase (DHFR) has been a well-recognized target for the treatment of many diseases. Based on 8,10-dideazaminopterins, which are classical antifolates that potently inhibit DHFR, it is designed a series of novel 2,4-diamino-6-substituted pyrido[3,2-d]pyrimidines. By removing the glutamate moiety and introducing lipophilic groups, it was hoped to improve passive diffuse through the cell membranes. The target compounds were efficiently synthesized using one-pot procedure and evaluated in vitro for DHFR inhibition and antitumor activity.

Compounds 5e, 5h, 5i and 5k were the most potent inhibitors of recombinant human DHFR (rhDHFR) with IC50values in the range 0.2–1.0 μM. Analysis using flow cytometric indicated that the effect of compound 5k on cell cycle progression was linked to induction of S phase arrest. Compounds 5g, 5h, 5i and 5k showed broad spectrum antitumor activity against four different tumor cell lines, with IC50values in the range 0.07–23 μM. Molecular docking investigations showed that the trimethoyphenyl ring of compound 5k occupied a position near the cofactor-binding site in the rhDHFR-inhibitor complex, with close intermolecular contacts with Asp21, Phe31, Ser59, Ile60 and Pro61.
