  A convenient ‘catch and release’ synthesis of fused 2-alkylthio-pyrimidinones mediated by polymer-bound BEMP

  摘要：

  A robust 'catch and release' synthesis of fused 2-alkylthio-3-substituted-pyrimidinones mediated by the polymer-bound base P-BEMP is described. This reengineered synthesis combines the efficiency of the classical synthesis (three steps, three diversity points) with the practical benefits of resin-bound reagents. The solution-phase strategy, reagent compatibility, and the results of a representative 48-member combinatorial library are described and presented herein. (C) 2003 Elsevier Science Ltd.

  treatments for CDI is a high priority. Toward this goal, we began in vitro screening of a structurally diverse in-house library of 67 compounds against two pathogenic C. difficile strains (ATCC BAA 1870 and ATCC 43255), which yielded a hit compound, 2-methyl-8-nitroquinazolin-4(3H)-one (2) with moderate potency (MIC = 312/156 μM). Optimization of 2 gave lead compound 6a (2-methyl-7-nitrothieno[3,2-d]pyrimidin-4(3H)-one)

  艰难梭菌感染（CDI）是美国医疗保健相关感染的主要原因。因此，开发用于CDI的新疗法是当务之急。为了实现这一目标，我们开始体外筛选针对两种致病性艰难梭菌菌株（ATCC BAA 1870和ATCC 43255）的67种化合物的结构多样的内部文库，产生的化合物为2-甲基-8-硝基喹唑啉酮- 4（3 H）-一（2），具有中等效力（MIC = 312/156μM）。2的最优化得到铅化合物6a（2-甲基-7-硝基硫代[3,2 - d ]嘧啶-4（3 H-1）具有增强的效价（MIC = 19/38μM），对正常肠道菌群的选择性，对哺乳动物细胞系的CC 50 s> 606μM ，以及在模拟的胃液和肠液中的可接受的稳定性。在C2-，N3-，C4-和C7位置上对6a的进一步优化导致了针对50多种化合物的文库，其针对艰难梭菌的临床分离株的MIC为3至800μM。化合物8f（MIC = 3/6μM）被确定为进一步优化的有希望的先导。
