Four pyrrolo[1,2-d][1,2,4]triazines and four thiazolo[3,4-d][1,2,4]triazines were synthesized from trans-4-hydroxy-L-proline and L-thiaproline, respectively. The synthetic route involved formation of hydrazides followed by cyclization with orthoesters. The proliferative response to human lymphocyte mitogen (phytohemagglutinin) revealed significant immunostimulant activity for all test drugs. Furthermore
由反式-4-羟基-L-脯氨酸和L-合成了四个吡咯并[1,2-d] [1,2,4]三嗪和四个噻唑并[3,4-d] [1,2,4]三嗪噻脯氨酸分别。合成途径包括形成酰肼,然后用原酸酯环化。对人淋巴细胞有丝分裂素(植物血凝素)的增殖反应表明,所有受试药物均具有显着的免疫刺激活性。此外,一些三嗪衍生物响应调理化酵母聚糖的刺激而有效激活吞噬细胞产生的游离氧自由基。
