Soluble guanylate cyclase (sGC), the endogenous receptor for nitric oxide (NO), has been implicated in several diseases associated with oxidative stress. In a pathological oxidative environment, the heme group of sGC can be oxidized becoming unresponsive to NO leading to a loss in the ability to catalyze the production of cGMP. Recently a dysfunctional sGC/NO/cGMP pathway has been implicated in contributing

鸟苷酸环化酶(sGC)是
一氧化氮(NO)的内源性受体,与多种与氧化应激有关的疾病有关。在病理性氧化环境中,sGC的血红素基团可被氧化而变得对NO无响应,从而导致催化cGMP产生的能力下降。最近,功能异常的sGC / NO / cGMP途径与青光眼相关的眼内压升高有关。在这里,我们描述了专门设计用于局部眼部给药的分子的发现,该分子可以激活氧化的sGC,恢复催化cGMP产生的能力。这些努力最终导致了化合物(+)-23的鉴定,可在单次局部滴眼后24小时内强烈降低眼内压升高的食蟹猴模型中的眼内压,已被选择用于临床评估。
