The C-15 senecioyl side chain of brusatol was interchanged with fluorinated acyl groups, and the C-3 hydroxy group of bruceolide was esterified with fluorinated acyl chlorides. These fluorinated quassinoids 11, 12, 13, and 17 showed significant cytotoxic activity against eight human cancer cell lines including small and non-small cell lung, colon, CNS, ovarian and renal cancers, leukemia, and melanoma
将Brusatol的C-15千碳酰侧链与
氟化酰基互换,并将Bruceolide的C-3羟基与
氟化酰
氯酯化。这些
氟化的类quasinoids 11、12、13和17对八种人类癌
细胞系(包括小细胞和非小细胞肺癌,结肠癌,CNS,卵巢癌和肾癌,白血病和
黑色素瘤)显示出显着的细胞毒性活性,其中17种的抗癌活性约为100倍比11、12和13具有更强的活性。在此体外
细胞系中,17的活性类似于Bruceantin(1)的活性。
