  摘要：

  为了研究3-叠氮基和24-酰胺化双重取代的作用，我们制备了一组由23种DCA，鹅去氧胆酸（CDCA）和石胆酸（LCA）的BA衍生物组成的新研究小组，在我们以前的研究中，这些特征分别与细胞毒性有关工作。使用3- [4,5-二甲基噻唑-2-基] -2,5-二苯基四唑溴化物（MTT）分析研究了化合物对HT-1080和Caco-2细胞活力的影响。为了了解细胞死亡的机制，使用流式细胞仪对具有降低细胞活力的高潜力化合物进行了进一步研究。用低微摩尔IC 50鉴定了几种化合物降低Caco-2和HT1080细胞系中细胞活力的数值，使其成为迄今报道的最有效的BA细胞凋亡因子之一。没有证据表明总体疏水性和细胞毒性之间存在联系，这支持了BA诱导细胞死亡可能是结构特异性的观点。衍生自DCA的化合物通过凋亡导致细胞死亡。有一些证据表明所研究的两种细胞系之间的选择性可能是由于CD95 / FAS的表达不同所致。毒性更大

• Bile acid toxicity structure–activity relationships: Correlations between cell viability and lipophilicity in a panel of new and known bile acids using an oesophageal cell line (HET-1A)

  The molecular mechanisms and interactions underlying bile acid cytotoxicity are important to understand for intestinal and hepatic disease treatment and prevention and the design of bile acid-based therapeutics.Bile acid lipophilicity is believed to be an important cytotoxicity determinant but the relationship is not well characterized. In this study we prepared new azido and other lipophilic BAs and altogether assembled a panel of 37 BAs with good dispersion in lipophilicity as reflected in RPTLC R-Mw. The MTT cell viability assay was used to assess cytotoxicity over 24 h in the HET-1A cell line (oesophageal). RMw values inversely correlated with cell viability for the whole set (r(2) = 0.6) but this became more significant when non-acid compounds were excluded (r(2) = 0.82, n = 29). The association in more homologous subgroups was stronger still (r(2) > 0.96). None of the polar compounds were cytotoxic at 500 mu M, however, not all lipophilic BAs were cytotoxic. Notably, apart from the UDCA primary amide, lipophilic neutral derivatives of UDCA were not cytotoxic. Finally, CDCA, DCA and LagoDCA were prominent outliers being more toxic than predicted by R-Mw. In a hepatic carcinoma line, lipophilicity did not correlate with toxicity except for the common naturally occurring bile acids and their conjugates. There were other significant differences in toxicity between the two cell lines that suggest a possible basis for selective cytotoxicity. The study shows: (i) azido substitution in BAs imparts lipophilicity and toxicity depending on orientation and ionizability; (ii) there is an inverse correlation between R-Mw and toxicity that has good predictive value in homologous sets; (iii) lipophilicity is a necessary but apparently not sufficient characteristic for BA cytocidal activity to which it appears to be indirectly related.
