Pentacyclic triterpenoids oleanolic acid, ursolic acid, betulinic acid, and platanic acid were acetylated and converted into several amides -; the cytotoxicity of which has been determined in sulforhodamine B assays employing seral human tumor cell lines and nonmalignant fibroblasts. Thereby, a betulinic acid/-1,4-cyclohexyldiamine amide showed excellent cytotoxicity (for example, EC = 0.6 μM for HT29 colon adenocarcinoma cells).
五环三萜齐墩果酸、熊果酸、白桦酸和角鲨烷被乙酰化，并转化为几种酰胺 - ；采用一系列人肿瘤细胞系和非恶性成纤维细胞，用磺酰罗丹明 B 测定法测定了它们的细胞毒性。由此，白桦酸/1,4-环己二胺酰胺表现出优异的细胞毒性（例如，对 HT29 结肠腺癌细胞的 EC = 0.6 μM）。
