(20R)-25-Methoxyl-dammarane-3 beta,12 beta,20-triol (25-OCH3(-)PPD, AD-1) is a dammarane-type sapogenin showing anti-tumor potential. In the search for new anti-tumor agents with higher potency than our previously identified compound 25-OCH3-PPD, 11 novel sulfamic acid and diacid derivatives that could improve water solubility and contribute to good drug potency and pharmacokinetic profiles were designed and synthesized. Their in vitro anti-tumor activities in MCF-7, A-549, HCT-116, and BGC-823 cell lines and one normal cell line were tested by standard MTT assay. Results showed that compared with compound 25-OCH3-PPD, compounds 1, 4, and 5 exhibited higher cytotoxic activity on almost all cell lines, together with lower toxicity in the normal cell. In particular, compound 1 exhibited the best anti-tumor activity in the in vitro assays. The water solubility of 25-OCH3-PPD and its derivatives was tested and the results showed that the solubility of 25-OCH3-PPD sulfamic acid and diacid derivatives were better than that of 25-OCH3-PPD in water, which may provide valuable data for the research and development of new anti-tumor agents.

(20R)-25-甲氧基达玛烷-3β,12β,20-三醇(25-OCH3-PPD,AD-1)是一种具有抗肿瘤潜力的达玛烷型皂苷元。为了寻找比之前发现的25-OCH3-PPD更有效的抗肿瘤药物,设计并合成了11种新型磺胺酸和双酸衍生物,旨在提高水溶性,并改善药物效力和药代动力学特性。通过标准MTT法,测定了这些化合物在MCF-7、A-549、HCT-116、BGC-823肿瘤细胞系和一种正常细胞系中的体外抗肿瘤活性。结果显示,与25-OCH3-PPD相比,化合物1、4和5在几乎所有细胞系中表现出更高的细胞毒性活性,且对正常细胞的毒性更低。其中,化合物1在体外试验中表现出最佳的抗肿瘤活性。测试了25-OCH3-PPD及其衍生物的水溶性,结果表明,25-OCH3-PPD的磺胺酸和双酸衍生物的水溶性优于25-OCH3-PPD,这可能为新型抗肿瘤药物的研究和开发提供有价值的数据。版权属于2017 Elsevier Inc.,保留所有权利。
