以2,4-二氨基-6-羟甲基吡啶并[3,2-d]嘧啶为原料, 在4-位氨基转换为羟基后与对氨基苯甲酰谷氨酸二乙酯连接生成叶酸类似物分子骨架, 采用Adams催化方法还原吡啶环, 在N5-位连接不同类型的取代基得到3个新的N8-去氮四氢叶酸类似物. 经1H NMR, MS对化合物的结构进行了表征. 初步生物活性结果表明, 此类化合物对人重组二氢叶酸还原酶的抑制活性与N5-位的取代基有关联.

The backbone of folate analogue was obtained by linking di-ethyl-N-(p-aminobenzoyl)-L- glutamate and 2-amino-4-hydroxy-6-(hydroxymethyl)pyrido[3,2-d]pyrimidine. Three new 8-deazatetra- hydrofolate analogues were synthesized after reducing the pyrimidine and linking different substituents on N5 position. The compounds were characterized by 1H NMR and MS techniques. The inhibitory activities of the compounds against human dihydrofolate reductase were determined. The re-sults showed that the bioactivities of the compounds were related with different substituents on N5 position.

Key words: N8-deaza-N5-substitutedtetrahydrofolate analogue, dihydrofolate reductase, anticancer activity
