  New 5-Aryl-1H-imidazoles Display in Vitro Antitumor Activity against Apoptosis-Resistant Cancer Models, Including Melanomas, through Mitochondrial Targeting

  摘要：

  We designed and synthesized 48 aryl-1H-imidazole derivatives and investigated their in vitro growth inhibitory activity in cancer cell lines known to present various levels of resistance to proapoptotic stimuli. The IC50 in vitro growth inhibitory concentration of these compounds ranged from >100 mu M to single digit mu M. Among the most active compounds, 2i displayed similar in vitro growth inhibition in cancer cells independent of the cells' levels of resistance to proapoptotic stimuli and was found to be cytostatic in melanoma cell lines. Compound 2i was then tested by the National Cancer Institute Human Tumor Cell Line Anti-Cancer Drug Screen, and the NCI COMPARE algorithm did not reveal any correlation between its growth inhibition profiles with the NCI database compound profiles. The use of transcriptomically characterized melanoma models then enabled us to highlight mitochondrial targeting by 2i. This hypothesis was further confirmed by reactive oxygen production measurement and oxygen consumption analysis.

  The synthesis and characterization of imidazole-containing macrocycles displaying planar chirality has been achieved. HLPC and NMR studies revealed the crucial role of the alicyclic chain length in determining the rate of stereoisomerisation: 15- and 16-membered cyclic compounds are chiral whereas their larger-ringed analogues equilibrate rapidly at room temperature. Computational calculations are
