A multistep route for the synthesis of N-[4-[(2,4-diamino-6-quinazolinyl)thio]benzoyl]-L-glutamic acid (2) from 4-mercaptobenzoic acid and 5-chloro-2-nitrobenzonitrile is described. Although this aminopterin analog lacked significant antimalarial activity, it was a potent inhibitor of dihydrofolate reductase from Trypanosoma cruzi. The pteroic ester analog 11, however, was active against Plasmodium
由4-巯基苯甲酸和5-氯-2-硝基苄腈合成N- [4-[(2,4-二氨基-6-喹唑啉基)硫代]苯甲酰基] -L-谷氨酸(2)的多步路线是描述。尽管该氨基蝶呤类似物缺乏显着的抗疟活性,但它是来自克鲁斯锥虫的二氢叶酸还原酶的有效抑制剂。然而,蝶呤酯类似物11在高剂量下对小鼠伯氏疟原虫感染具有活性。
