affinity of prodrugs for metabolic enzymes for efficient activation of the prodrugs in the body. Although many prodrugs have been synthesized with consideration of these chemical properties, there has been little study on the design of a structure with consideration of biological properties such as substrate recognition ability of metabolic enzymes. In this report, chemical synthesis and evaluation of indomethacin
必须考虑前药对代谢酶的亲和力,以有效激活体内的前药。尽管考虑到这些化学性质已经合成了许多前药,但是关于结构设计的研究还很少考虑到生物学性质,例如代谢酶的底物识别能力。在此报告中,描述了由人羧酸酯酶1(hCES1)代谢激活的消炎痛前药的化学合成和评估。将合成的前药在人肝微粒体(HLM),人肠微粒体(HIM)和hCES1溶液中进行水解反应,并研究水解参数以评估这些前药的水解速率并阐明hCES1的底物识别能力。发现在HLM,HIM和hCES1溶液中,水解速率的变化取决于酯的空间位阻和立体化学。此外,在hCES1催化的水解反应中,V最大的值Ñ具有化学反应性高丁基硫酯比的混合物显著降低Ñ丁基酯。
