improving the solubility and mouse pharmacokinetic profile of JSF-2019 and culminated in JSF-2513, relying on the key introduction of a morpholine. Mechanistic studies with JSF-2019, JSF-2513, and other triazines stressed the significance of achieving potent in vitro efficacy via release of intrabacterial NO⋅ along with inhibition of InhA and, more generally, the FAS-II pathway. This study highlights the importance
由于三嗪类抗结核JSF-2019的体外功效以及与临床相关的地拉曼胺和前驱体胺共有的硝基基团,因此引起了人们的关注。JSF-2019的激活需要D420之外还需要F420H2和一种或多种硝基还原酶。利用细菌内药物代谢(IBDM)平台演示了系统动力学,证明了NO⋅和去硝基代谢产物的形成。构效关系研究专注于提高JSF-2019的溶解度和小鼠药代动力学特征,并以吗啉的关键引入为基础,最终在JSF-2513中达到顶峰。使用JSF-2019,JSF-2513和其他三嗪的机理研究强调了通过释放细菌内NO⋅以及抑制InhA以及更普遍地抑制FAS-II途径达到有效的体外功效的重要性。
