New 2,3-secolupane derivatives with methylketone, acetylhydrazone, and 1,3,4-oxadiazoline fragments were prepared via chemical modification of ring A and the isopropylene group of 1-cyano-2,3-secotriterpenoids. Cytotoxicity studies of the synthesized compounds using four tumor cell lines (HEp-2 human epithelial type 2 carcinoma, MS melanoma, RD TE32 rhabdomyosarcoma, and A549 lung carcinoma) showed
新的 2,3-secolupane 衍生物与甲基酮、乙酰腙和 1,3,4-恶二唑啉片段是通过环 A 和 1-氰基-2,3-secotriterpenoids 的异丙烯基团的化学修饰制备的。使用四种肿瘤细胞系(HEp-2 人类上皮 2 型癌、MS 黑色素瘤、RD TE32 横纹肌肉瘤和 A549 肺癌)对合成化合物的细胞毒性研究表明,3,30-二醛 3 (IC50 3.98 μM) 和 30-乙酰腙10 (IC50 8.95 μM) 对 MS 黑色素瘤细胞的细胞毒性最强。中间体 3 对 RD TE32 横纹肌肉瘤细胞也有活性(IC50 6.70 μM)。
