Thieno[2,3-b]pyridines—A new class of multidrug resistance (MDR) modulators
摘要:
To identify new potent multidrug resistance modulators, we have synthesized a series of novel thieno[ 2,3-b]pyridines and furo[2,3-b] pyridines, and examined their stucture-activity relationships. All synthesized compounds were tested to determine BCRP1, P-gp, and MRP1 inhibitor activity, and most potent MDR modulators were also screened for their toxicity, cytotoxicity and Ca2+ channel antagonist activity. Among these compounds, thieno[2,3-b] pyridine (6r) was found to exhibit a potent P-gp inhibitory action with EC50 = 0.3 +/- 0.2 mu M, MRP1 inhibitory action with EC50 = 1.1 +/- 0.1 mu M and BCRP1 inhibitory action with EC50 = 0.2 +/- 0.05 mu M and may represent suitable candidate for further pharmacological studies.

A series of pyridine, pyrane, and pyrimidine derivatives (2-11) were newly synthesized using nitrobenzosuberone 1 as a starting material. The antitumor activities of the synthesized compounds were evaluated utilizing 59 different human tumor cell lines, representing leukemia, melanoma, lung, colon, brain, ovary, breast, prostate as well as kidney. Some of the tested compounds especially 2, 3, 4c, 6

arylmethylenecyanoacetamide. The synthesis of the fused-ring pyranes 8 and 9 involved the condensation of the ketones 4 and 5 with malononitrile under basic conditions. The rearrangement of 8 under acidic conditions gave the tetrahydropyridine 10. The pyran 20 was obtained from 15 and benzaldehyde. The screening tests showed that many of the compounds obtained exhibit good anticancer activity comparable to
