In this work, five new hybrids of phenylsulfonylfuroxan merging 3-benzyl coumarin and their seco-B-ring derivatives 2–6 were designed and synthesized. Among them, compound 3 showed the most potent antiproliferation activities with IC50 values range from 0.5 to 143 nM against nine drug-sensitive and four drug-resistant cancer cell lines. Preliminary pharmacologic studies showed that these compounds

香豆素的五个新的杂种及其开环- B-环衍
生物2 - 6设计并合成。其中,化合物3对9种药敏和4种耐药的癌
细胞系表现出最强的抗增殖活性,IC 50值在0.5至143 nM之间。初步的药理研究表明,这些化合物的毒性比
铅化合物1低。化合物3明显诱导A2780的早期凋亡,几乎不影响A2780的细胞周期,这与化合物1有显着差异。。尤其是,与对药物敏感的MCF-7和KB相比,在过表达P-gp的耐药癌
细胞系MCF-7 / ADR和KB-V中,它具有559倍和294倍的选择性抗增殖活性,这表明化合物2 – 6可能具有P-gp过表达的抗MDR癌症的额外机制。
