The chemical synthesis of three close analogues (2-4) of N10-propargyl-5,8-dideazafolate (PDDF) is described. The quinazoline ring of 2 and 4 was constructed from the pivotal intermediate 9 in a novel and unambiguous manner during the final step of the synthesis under very mild conditions. 2-Desamino-2-methyl-N10-propargyl-5,8-dideazafolate (DMPDDF) (2) was a strong inhibitor of human and Lactobacillus
描述了N10-炔丙基-5,8-二氮杂叶酸酯(PDDF)的三个紧密类似物(2-4)的化学合成。在非常温和的条件下,在合成的最后步骤中,由枢轴中间体9以新颖且明确的方式构造了2和4的喹唑啉环。2-Desamino-2-methyl-N10-propargyl-5,8-dideazafolate(DMPDDF)(2)是人和干酪乳杆菌胸苷酸合酶的强抑制剂,而2-desamino-2-(三氟甲基)-N10-propargyl- 5,8-二脱氮叶酸酯(3)和2-脱氨基-2,3-二甲基-N10-炔丙基-5,8-二脱氮叶酸酯(4)只是该酶的弱抑制剂。DMPDDF对培养的Manca人淋巴白血病和H35肝癌细胞具有极好的生长抑制作用。在这些细胞系中,2的抑制剂活性分别比PDDF高43倍和65倍。由于运输缺陷而对甲氨蝶呤具有抗性的H35R细胞对DMPDDF具有交叉抗性,而对PDDF无交叉抗性。与H35N细胞相比
