  Synthesis and antimycobacterial activity of 5-formylaminopyrimidines; analogs of antibacterial purines

  摘要：

  Pyrimidine analogs of antimycobacterial purines have been synthesized and their biological activities evaluated. Several 5-formamidopyrimidines exhibited profound activity against Mycobacterium tuberculosis in vitro (IC90 <= 1.5 mu g/mL), and they were essentially inactive against other bacteria.

  Synthesis and biological evaluation of pyrimidine analogs of antimycobacterial purines

  摘要：

  Pyrimidine analogs of antimycobacterial 6-aryl-9-benzylpurines have been synthesized and screened for antibacterial activity against Mycobacterium tuberculosis H(37)Rv in vitro. Several active compounds were identified and the best results were observed for 5-formamidopyrimidines. These compounds generally displayed IC(90) values <= 1 mu g/mL, and they exhibited low toxicity towards mammalian cells. Imidazolylpyrimidines, which may be regarded as fleximer analogs of the parent purines, were also synthesized and one of them was found to be quite a potent inhibitor of M. tuberculosis (IC(90) 14 mu g/mL).

  A Number of 6-(2-furyl)-9-(p-methoxybenzyl)purines carrying a variety of substituents in the 2- or 8-position have been synthesized and their ability to inhibit growth of mycobacterium tuberculosis in vitro has been determined. It is demonstrated that sterical hindrance in the purine 8-position reduces activity and that C-8 should be unsubstituted. In the purine 2-position small, hydrophobic substituents are beneficial. The electronic properties of the 2-substituents appear to have only a minor influence on bioactivity. The compounds studied exhibit low toxicity toward mammalian cells (VERO cells) and are essentially inactive toward Staphylococcus aureus and Escherichia coli. The most active and selective antimycobacterial in the series detected to date is the novel 2-methyl-6-furyl-9-(p-methoxybenzyl)purine with MIC = 0.20 ug/mL- against M. tuberculosis and IC50 against VERO cells >62.5 mu g/ mL. Also the novel 2-fluoro analog and the previously known 2-chloro compound, both with MIC = 0.39 mu g/mL, are highly interestinq drug candidates. (C) 2007 Elsevier Ltd. All rights reserved.
