Design, synthesis and biological activity of N 5-substituted tetrahydropteroate analogs as non-classical antifolates against cobalamin-dependent methionine synthase and potential anticancer agents.

Abstract
Cobalamin-dependent methionine synthase (MetH) is involved in the process of tumor cell growth and survival. In this study, a novel series of N5-electrophilic substituted tetrahydropteroate analogs without glutamate residue were designed as non-classical antifolates and evaluated for their inhibitory activities against MetH. In addition, the cytotoxicity of target compounds was evaluated in human tumor cell lines. With N5-chloracetyl as the optimum group, further structure research on the benzene substituent and on the 2,4-diamino group was also performed. Compound 6c, with IC50 value of 12.1 μM against MetH and 0.16-6.12 μM against five cancer cells, acted as competitive inhibitor of MetH. Flow cytometry studies indicated that compound 6c arrested HL-60 cells in the G1-phase and then inducted late apoptosis. The molecular docking further explained the structure-activity relationship.

Synthesis and antiproliferative activity of a series of novel 6-substituted pyrido[3,2-d]pyrimidines as potential nonclassical lipophilic antifolates targeting dihydrofolate reductase. Eur J Med Chem 2017; 128:88-97. [PMID: 28152430 DOI: 10.1016/j.ejmech.2017.01.033] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2016] [Revised: 01/20/2017] [Accepted: 01/21/2017] [Indexed: 10/20/2022]
Abstract
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, we have designed a series of novel 2,4-diamino-6-substituted pyrido[3,2-d]pyrimidines. By removing the glutamate moiety and introducing lipophilic groups, we 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 IC50 values 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 IC50 values 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.
