Natural products have served as inspirational scaffolds for the design and synthesis of novel antineoplastic agents. Here we present our preliminary efforts on the synthesis and biological evaluation of a new class of electrophilic steroids inspired by the naturally occurring taccalonolides. We demonstrate that these simplified analogs exhibit highly persistent antiproliferative properties similar to the taccalonolides and retain activity against resistant cancer cell lines that warrants further preclinical development.
天然产物一直是设计和合成新型抗肿瘤药物的灵感来源。在此,我们展示了我们在合成和生物学评估一类受天然存在的塔克醇内酯启发的新型亲电甾体方面的初步努力。我们证明,这些简化的类似物表现出与塔克醇内酯相似的高度持久的抗增殖特性,并对耐药癌细胞系保持活性,这值得进一步进行临床前开发。
