ring within pocket A of the enzyme. On this basis, chemical modifications were proposed to increase inhibition activity. Synthetic routes had to be adapted and optimized to yield the desired substituted 4- and 5-arylthiazolinethiones. Their biological evaluation shows that 5-aryl regioisomers are systematically less potent than the corresponding 4-aryl analogs. Substitution on the phenyl ring does not
4-苯基噻唑啉硫酮对人 IDO1 的对接研究表明,环外硫原子与血红素铁的络合进一步被酶口袋 A 内苯环的疏水相互作用增强。在此基础上,提出了化学修饰以增加抑制活性。合成路线必须进行调整和优化以产生所需的取代 4-和 5-芳基噻唑啉硫酮。他们的生物学评估表明,5-芳基区域异构体的效力低于相应的 4-芳基类似物。除 4-Br 和 4-Cl 衍生物外,苯环上的取代不会显着增加抑制效力。
