P1-1) inhibitor with weak antiproliferative ability in tumor cells. By use of the principle of bioisosterism, a series of novel EA oxadiazole analogues were designed and synthesized. The structure−activity relationships of inhibiting GST P1-1 activity and cell proliferation of those EA analogues were investigated in human leukemia HL-60 cells. Our data revealed that those EA oxadiazole analogues had improved
乙二酸(EA)是一种谷胱甘肽S-转移酶P1-1(GST P1-1)抑制剂,在肿瘤细胞中具有较弱的抗增殖能力。利用生物立体异构原理,设计并合成了一系列新型的EA恶二唑类似物。在人白血病HL-60细胞中研究了抑制GST P1-1活性与那些EA类似物的细胞增殖的构效关系。我们的数据显示,那些EA恶二唑类似物具有更好的抗增殖活性,并且大多数与EA相比对GST P1-1活性具有相似或更好的抑制作用。化合物6u是有效的抗增殖剂之一,没有抑制GST P1-1活性。化合物6r和6s在几种实体瘤细胞系中是两种有效的细胞生长抑制剂,其浓度可抑制一半的细胞生长,其浓度低于5μM。我们的数据表明,这些EA恶二唑类似物是有望通过GST P1-1抑制依赖性和/或非依赖性途径发挥作用的抗肿瘤药物。
