A novel series of 14 nonclassical 6-substituted pyrrolo[2,3-d]pyrimidines 2a - 2n were designed as potential inhibitors of thymidylate synthase, based on previously reported 2-amino-4-oxopyrrolo[2,3-d]-pyrimidines 1a and 1b. The synthesis of the target compounds 2a-2n was accomplished by nucleophilic displacement of the mesylate 11 with appropriately substituted aromatic thiols. Most of the target
一种新的系列14非经典6-取代吡咯并[2,3的d ]嘧啶2A - 2n个被设计为胸苷酸合成酶的潜在抑制剂,基于先前报道的2-氨基-4-氧代吡咯并[2,3- d ] -pyrimidines 1a和1b。目标化合物2a-2n的合成通过用适当取代的芳族硫醇亲核置换甲磺酸酯11来完成。在测试浓度下,大多数目标化合物均未显示出对大肠杆菌胸苷酸合酶或重组人胸苷酸合酶的抑制作用。但是化合物2h(2,4-dichloro),2j(3,4-二氯)和2m(4-硝基)在23μM,23μM和24μM时确实显示出25%,40%和35%的人胸苷酸合酶抑制作用。这些观察结果与先前的报道一致,这些报道表明侧链芳环上的强吸电子取代基有助于抑制胸苷酸合酶。
