  Synthesis and antitumor activity of N-sulfonyl-3,7-dioxo-5β-cholan-24-amides, ursodeoxycholic acid derivatives

  摘要：

  A series of N-sulfonyl-3,7-dioxo-5 beta-cholan-24-amides, ursodeoxycholic acid derivatives, have been designed and synthesized in nine steps starting from ursodeoxycholic acid. The in vitro antitumor activity of the target compounds has been evaluated against HCT-116, MCF-7, K562, and SGC-7901 cell lines. The pharmacological results showed that most of the prepared compounds display excellent selective cytotoxicity toward HCT-116, MCF-7, and K562 cell lines. Particularly, compounds 10c, 10f and 10g show high inhibitory activity on these human cancer cell lines (IC50: 2.39-9.34 mu M). Conversely, all compounds are generally inactive against SGC-7901, with only 10b having IC50 below 50 mu M. Crown Copyright (c) 2012 Published by Elsevier Inc. All rights reserved.

• 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.

• Design, Synthesis, and Biological Evaluation of Potent Dual Agonists of Nuclear and Membrane Bile Acid Receptors

  Bile acids exert genomic and nongenomic effects by interacting with membrane G-protein-coupled receptors, including the bile acid receptor GP-BAR1, and nuclear receptors, such as the farnesoid X receptor (FXR). These receptors regulate overlapping metabolic functions; thus, GP-BAR1/FXR dual agonists, by enhancing the biological response, represent an innovative strategy for the treatment of enteroendocrine disorders. Here, we report the design, total synthesis, and in vitro/in vivo pharmacological evaluation of a new generation of dual bile acid receptor agonists, with the most potent compound, 19, showing promising pharmacological profiles. We show that compound 19 activates GP-BAR1, FXR, and FXR regulated genes in the liver, increases the intracellular concentration of cAMP, and stimulates the release of the potent insulinotropic hormone GLP-1, resulting in a promising drug candidate for the treatment of metabolic disorders. We also elucidate the binding mode of the most potent dual agonists in the two receptors through a series of computations providing the molecular basis for dual GP-BAR1/FXR agonism.

  Bile acids are signaling molecules interacting with the nuclear receptor FXR and the G-protein coupled receptor 1 (GP-BAR1/TGR5). GP-BAR1 is a promising pharmacological target for the treatment of steatohepatitis, type 2 diabetes, and obesity. Endogenous bile acids and currently available semisynthetic bile acids are poorly selective toward GP-BAR1 and FXR. Thus, in the present study we have investigated around the structure of UDCA, a clinically used bile acid devoid of FXR agonist activity, to develop a large family of side chain modified 3 alpha,7 beta-dihydroxyl cholanoids that selectively activate GP-BAR1. In vivo and in vitro pharmacological evaluation demonstrated that administration of compound 16 selectively increases the expression of proglucagon 1, a GP-BAR1 target, in the small intestine, while it had no effect on FXR target genes in the liver. Further, compound 16 results in a significant reshaping of bile acid pool in a rodent model of cholestasis. These data demonstrate that UDCA is a useful scaffold to generate novel and selective steroidal ligands for GP-BAR1.
