Novel pyrrolo[2, 3-d]pyrimidine antifolates (1a, b and 2a, b) with a nitrogen atom in the bridge chain between the 2, 4-diaminopyrrolo[2, 3-d]pyrimidine and phenylene rings were designed and efficiently synthesized. These compounds exhibited more potent inhibitory activities than methotrexate (MTX) against the proliferation of human epidermoid carcinoma KB cells and human non-small cell lung carcinoma A549 cells despite their modest dihydrofolate reductase (DHFR)-inhibitory potency.
设计并高效合成了在 2,4-二氨基吡咯并[2,3-d]嘧啶和亚苯基环之间的桥链中含有一个氮原子的新型吡咯并[2,3-d]嘧啶抗酚类化合物(1a,b 和 2a,b)。这些化合物对人表皮样癌 KB 细胞和人非小细胞肺癌 A549 细胞的增殖具有比甲氨蝶呤(MTX)更强的抑制活性,尽管它们的二氢叶酸还原酶(DHFR)抑制效力并不强。
