diethylmalonate, malononitrile, ethyl cyanoacetate, and thiourea yielding fused pyrazole derivatives. Some of the new compounds were reacted with cyclic and acyclic sugars to produce new S‐, O‐, and N‐glycoside derivatives. The antitumor activity against the human breast cancer cells (MCF‐7) was assessed. Four of the new compounds showed IC50 values less than those of the positive control, indicating that these
4-(4-氯亚苄基)-2,5-二苯基-2,3-二氢-3 H-吡唑-3-1-3one 3a和4-(3,4-二甲氧基亚苄基)-5-苯基-2,3-二氢制备了3 H-吡唑-3-酮3b并将其与苯肼,硫代氨基脲,盐酸羟胺,乙酰乙酸乙酯,二乙基丙二酸酯,丙二腈,氰基乙酸乙酯和硫脲反应,生成稠合的吡唑衍生物。一些新化合物与环状和无环糖反应生成新的S-,O-和N-糖苷衍生物。评估了对人类乳腺癌细胞(MCF-7)的抗肿瘤活性。四个新化合物的IC 50值 该值小于阳性对照的值,表明这四种化合物比阿霉素是更好的抗癌剂。
