设计、合成了24个新的2,5-二芳基-1,3,4-恶二唑啉类化合物(CA-4,1),并对其生物活性进行了评价。这些化合物代表两种结构类别; I型类别在A环上具有三个甲氧基,II型类别在A环上具有单个甲氧基。生物学评价表明,多种结构特征控制生物学效价。四种化合物,2-(3 '-溴苯基)-5-(3”,4”,5”-三甲氧基苯基)-2-乙酰基-2,3-二氢-1,3,4-恶二唑啉(9 L),2-(2 ',5'-二甲氧基苯基)-5-(3”-甲氧基苯基)-2-乙酰基-2,3-二氢-1,3,4-恶二唑啉(10 h),2-(3 ',4',5 '-三甲氧基苯基)-5-(3”-甲氧基苯基)-2-乙酰基-2,3-二氢-1,3,4-恶二唑啉(10 i)和2-(3 ′,5 ′-二甲氧基苯基)-5-(3 ″-甲氧基苯基)-2-乙酰基-2,3-二氢-1,3,4-恶二唑啉(10 j)对多种癌细胞系具有有效的抗增殖活性。机理研究表明,它们保留了化合物1的微管破坏作用,包括微管损失、异常有丝分裂纺锤体的形成和有丝分裂停滞。化合物10 i抑制纯化的微管蛋白聚合并避免由P-糖蛋白和βIII微管蛋白表达介导的耐药性。恶二唑啉类似物10 i是一个很有前途的先导化合物,值得进一步研究。
Twenty-four novel 2,5-diaryl-1,3,4-oxadiazoline analogs of combretastatin A-4 (CA-4, 1) were designed, synthesized and evaluated for biological activities. The compounds represent two structural classes; the Type I class has three methoxy groups on the A ring and the Type II class has a single methoxy group on the A ring. Biological evaluations demonstrate that multiple structural features control the biological potency. Four of the compounds, 2-(3’-bromophenyl)-5-(3”,4”,5”-trimethoxyphenyl)-2-acetyl-2,3-dihydro-1,3,4-oxadiazoline (9l), 2-(2’,5’-dimethoxyphenyl)-5-(3”-methoxyphenyl)-2-acetyl-2,3-dihydro-1,3,4-oxadiazoline (10h), 2-(3’,4’,5’-trimethoxyphenyl)-5-(3”-methoxyphenyl)-2-acetyl-2,3-dihydro-1,3,4-oxadiazoline (10i) and 2-(3’,5’-dimethoxyphenyl)-5-(3”-methoxyphenyl)-2-acetyl-2,3-dihydro-1,3,4-oxadiazoline (10j), have potent antiproliferative activities against multiple cancer cell lines. Mechanistic studies indicate that they retain the microtubule disrupting effects of compound 1 including microtubule loss, the formation of aberrant mitotic spindles, and mitotic arrest. Compound 10i inhibits purified tubulin polymerization and circumvents drug resistance mediated by P-glycoprotein and βIII tubulin expression. The oxadiazoline analog 10i is a promising lead candidate worthy of further investigation.
