Novel pyrimidinyl pyrazole derivatives were synthesized and examined for cytotoxic and antitumor activity. Mannich reaction was employed to construct this scaffold. Among the compounds synthesized, a series of propene derivatives exhibited a potent cytotoxic activity against some tumor cell lines including multidrug resistant cell lines due to the overexpression of P-glycoprotein. The vinyl bond moiety in the scaffold was believed to be required for the cytotoxic activity. Among them, compound 14g, when administered intraperitoneally, showed potent antitumor activity against the malignant ascites caused by intraperitoneal inoculation of P388 cells in mice. This compound also showed high activity against a solid tumor Meth A mouse fibrosarcoma when administered both intraperitoneally and orally.
新型的嘧啶基吡唑衍生物被合成并检测了其细胞毒性和抗肿瘤活性。通过Mannich反应构建了这一骨架。在合成的化合物中,一系列丙烯衍生物对某些肿瘤细胞系(包括由于P-糖蛋白过度表达而产生多药耐药性的细胞系)表现出强大的细胞毒活性。骨架中的乙烯键部分被认为是产生细胞毒活性的必要条件。其中,化合物14g通过腹腔给药,对小鼠因腹腔接种P388细胞引起的恶性腹水显示出强大的抗肿瘤活性。此化合物无论是腹腔注射还是口服,对Meth A小鼠纤维肉瘤这一实体瘤也显示出高活性。
