A series of estrone derivatives, 2⁻4, were synthesized from the corresponding arylidine estrone, 2a,b, as starting materials, which were prepared by condensation of estrone (3-hydroxy-estran-17-one, 1) with 4-bromobenzaldehyde and thiophene-2-aldehyde. Treating of 2a,b with hydrazine derivatives in acetic acid or propionic acid afforded pyrazoline derivatives, 3a⁻f and 4a⁻f, respectively. Furthermore
以相应的芳基雌酮2a,b为起始原料,合成了一系列雌酮衍生物2⁻4,它们是通过将雌酮(3-羟基-estran-17-one,1)与4-溴苯甲醛缩合而制得的和噻吩-2-醛。用肼衍生物在乙酸或丙酸中处理2a,b,分别得到吡唑啉衍生物3a⁻f和4a⁻f。此外,结果证明了噻吩基衍生物对MCF-7癌细胞的细胞毒性作用优于4-溴苯酚衍生物。体内异种移植乳腺癌动物模型实验表明,合成的衍生物可用于减少肿瘤体积,而最有效的衍生物(4f)在12天后可将肿瘤体积的发生减少约87.0%。
