analogues that retain key functional groups required for biological activity including the reactive cyclopropylmethyl carbinol and α,β-unsaturated ketone. As described here, we synthesized a variety of urea, carbamate, and sulfonamide derivatives that retain key functional groups and display potent biological activity toward target solid tumor cells in vitro but are relatively nontoxic toward a nontarget
Illudin S和M(1,2)处于担子菌发现剧毒倍半萜Omphalotus illudens。伊路菌素具有较低的治疗指数,但酰基富烯衍生物对多种耐多药肿瘤表现出有效的体内抗肿瘤活性。酰基富勒酸铅(4),伊洛富尔芬(5),在一项IIB期随机临床试验中,转移性激素难治性前列腺癌患者在两种不同的标准化学治疗方案治疗之前均无效,从而显着提高了其总生存率。依洛富芬是独特的,因为伯烯丙基羟基可被多种亲核试剂取代以生成类似物,这些类似物保留了生物活性所需的关键官能团,包括反应性环丙基甲基甲醇和α,β-不饱和酮。如此处所述,我们合成了多种尿素,氨基甲酸酯和磺酰胺衍生物,这些衍生物保留了关键的功能基团,并在体外对目标实体瘤细胞表现出强大的生物活性,但对非目标B细胞衍生的细胞系则无毒。
