4-triazole-3-carboximidate (4) and ethyl 1-beta-D-ribofuranosyl-1,2,4-triazole-3-carboxamidate (6) were synthesized and tested for antitumor and antiviral activity. A new facile synthesis of 1-beta-D-ribofuranosyl-1,2,4-triazole-3-carboxamidine hydrochloride (5), starting with imidate 4, was also developed. The imidates 4 and 6 differed greatly in solubility and dosing requirements. Even so, both compounds exhibited
合成了1-β-D-呋喃呋喃糖基甲基1,2,4-三唑-3-羧甲酸酯(4)和1-β-D-呋喃呋喃糖基1,2,4-三唑-3-氨基甲酸酯乙酯(6)经测试具有抗肿瘤和抗病毒活性。从亚氨酸酯4开始,还开发了一种新的简便的1-β-D-呋喃核糖基-1,2,4-三唑-3-羧am盐酸盐的合成方法(5)。酰亚胺4和6在溶解度和剂量要求上差别很大。即使这样,这两种化合物在体内也显示出对鼠白血病L1210的显着活性。用4的无毒剂量也可大大减少Friend白血病引起的脾肿大。相反,亚氨酸酯在体外均无活性。
