sensor protein with emerging therapeutic indications. To address the insufficient stability of CITCO, which limits its therapeutic potential, the E- and Z-isomers of CITCO were synthesized and characterized by X-ray crystallography, one- and two-dimensional NMR spectroscopy. The two isomers were found to undergo E/Z isomerizations in solution likely via a protonation-rotation mechanism, time- and con
CITCO(6-(4-氯苯基)咪唑并[2,1- b ] [1,3]噻唑-5-甲醛-O-(3,4-二氯苄基)肟)是人类组成型雄甾烷受体的广泛激动剂(hCAR),一种具有新兴治疗适应症的关键肝异种传感器蛋白。为了解决CITCO的不足稳定性,限制其治疗潜力,合成了CITCO的E-和Z-异构体,并通过X射线晶体学,一维和二维NMR光谱进行了表征。发现这两种异构体在溶液中可能通过质子旋转机制在时间和浓度上进行E / Z异构化。我们的分子建模研究表明,两种立体异构体均可与hCAR结合。
