Nitroxyl (HNO), a one-electron-reduced form of nitric oxide, has various biological activities, including a cardioprotective effect. Here, we first synthesized another, more hydrophilic photocontrollable HNO donor (3), which can release HNO in a spatially and temporally controlled manner, and then examined the properties of our series of compounds as practical HNO donors in a cellular system under photocontrol. We selected compound 2 as the preferred donor, and used it to show that calcitonin gene-related peptide (CGRP) can be upregulated in A549 cells via photocontrolled HNO release. This result demonstrates the suitability of this photocontrollable HNO donor for biological investigations.
一氧化氮(HNO)是一氧化氮的一种单电子还原形式,具有多种生物活性,包括保护心脏的作用。在这里,我们首先合成了另一种亲水性更强的光控 HNO 供体(3),它能以空间和时间可控的方式释放 HNO,然后考察了我们的系列化合物在光控下的细胞系统中作为实用 HNO 供体的特性。我们选择了化合物 2 作为首选供体,并用它证明了降钙素基因相关肽 (CGRP) 可通过光控 HNO 释放在 A549 细胞中上调。这一结果证明了这种光控 HNO 供体在生物研究中的适用性。
