The title compounds were synthetized by the reaction of TRIS with p-nitrophenyl or alkyl esters of N-carboxymethyl derivatives of uracil, 5-chloro-, 5-bromo-, 5-iodouracil, thymine, cytosine, 6-azauracil, 2-pyridone, 2-pyrimidone, 3-pyridazone and orotic acid. The following novel N-carboxymethyl derivatives are also described: 6-azauracil derivative VIIa by condensation of 4-thio-6-azauracil with methyl bromoacetate followed by hydrolysis, 5-chloruracil derivative IIIa by chlorination of uracil compound IIa, 2-pyrimidone (IXa) and 3-pyridazone derivative Xa by the reaction of the sodium salts of the bases with sodium chloracetate. Of all the amides tested, only the 3-pyridazone derivative Xd and orotic acid derivative XIId inhibited the growth of L-1210 mouse leukemic cells in vitro with 1D50 approx. 10-4 mol l-1.
这个标题化合物是通过TRIS与N-羧甲基尿嘧啶衍生物、5-氯、5-溴、5-碘尿嘧啶、胸腺嘧啶、胞嘧啶、6-氮杂尿嘧啶、2-吡啶酮、2-嘧啶酮、3-吡啶唑和乳酸反应合成的。此外,还描述了以下新的N-羧甲基衍生物:通过4-硫代-6-氮杂尿嘧啶与溴乙酸甲酯缩合后水解得到的6-氮杂尿嘧啶衍生物VIIa,通过氯化尿嘧啶化合物IIa得到的5-氯尿嘧啶衍生物IIIa,以及通过碱基的钠盐与氯乙酸钠反应得到的2-嘧啶酮(IXa)和3-吡啶唑衍生物(Xa)。在测试的所有酰胺中,只有3-吡啶唑衍生物Xd和乳酸衍生物XII d能够在体外抑制L-1210小鼠白血病细胞的生长,1D50约为10-4mol/L。
