Ortho-substituted polymethoxydiarylazolopyrimidines were synthesized using polymethoxysubstituted benzaldehydes and acetophenones as starting material. X-ray crystallography data clearly confirmed that the subsequent cyclization of 3-amino-1,2,4-triazole with ketoaldehydes yielded polymethoxyphenylsubstituted 6,7-diaryl-[1,2,4]triazolo[1,5-a]pyrimidines as single isomers. All compounds were evaluated
邻位取代的多甲氧基二芳基唑并嘧啶是使用多甲氧基取代的苯甲醛和苯乙酮作为原料合成的。X 射线晶体学数据清楚地证实,随后 3-氨基-1,2,4-三唑与酮醛环化产生多甲氧基苯基取代的 6,7-二芳基-[1,2,4] 三唑并 [1,5-a] 嘧啶,如单一异构体。使用表型海胆胚胎测定法在体内评估所有化合物。6-(4-甲氧基苯基)-7-(3,4,5-三甲氧基苯基)吡唑并[1,5a]嘧啶显示抗有丝分裂微管不稳定活性。已经提出了二芳基三唑并嘧啶中芳环取代基对其抗增殖抗微管蛋白作用的重要性。
