1-Phenyl-4-benzoyl-1H-1,2,3-triazoles as Orally Bioavailable Transcriptional Function Suppressors of Estrogen-Related Receptor α
摘要:
Estrogen-related receptor a is a potential candidate target for therapeutic treatment of breast cancer. We describe the discovery and structure activity relationship study of a series of 1-phenyl-4-benzoyl-1H-1,2,3-triazoles as novel suppressors of ERR alpha transcriptional functions. The most promising compound, 2-aminophenyl-(1-(3-isopropylpheny1)-1H-1,2,3-triazol-4-yl)methanone (14n), potently suppressed the transcriptional functions of ERR alpha with IC50 = 0.021 mu M in a cell-based reporter gene assay and also decreased both the mRNA levels and the protein levels of ERR alpha and the downstream targets. This compound inhibited the proliferation and migration of breast cancer cells with high level of ERR alpha. Preliminary pharmacolcinetic studies suggested that it possessed a good pharmacokinetic profile with an oral bioavailability of 71.8%. The compounds may serve as novel small molecule probes for further validation of ERR alpha as a molecular target for anticancer drug development.

In this work, an interesting procedure for the synthesis of α,β-unsaturatedamides from aryl azides and alkenylaluminum reagent has been developed. With palladium as the catalyst and XPhos as the ligand under carbon monoxide pressure, the desired α,β-unsaturatedamides were isolated in good to excellent yields with good functional group tolerance. Remarkably, this procedure also represents an example

The synthesis of α-carbonyl-α′-amide sulfoxonium ylides by Pd/C-catalyzed carbonylative transformation of azides with α-carbonyl sulfoxonium ylides has been studied. This method offers a direct approach to produce synthetically useful α-carbonyl-α′-amide sulfoxonium ylides in high efficiency. By using readily available substrates, 39 examples of products were prepared in good yields with outstanding
