8-Nitro-cGMP was recently discovered as a second messenger of nitric oxide. We describe here the synthesis and properties of DMACM-modified 8-nitro-cGMP for photochemical uncaging. Owing to the limited photostability of 8-nitro-cGMP care must be taken, but the photorelease of the intact product was readily feasible. Unexpectedly, 8-nitro-cGMP decays under formation of 8-nitrosoguanine when irradiated with light.
最近发现 8-硝基-cGMP 是
一氧化氮的第二信使。我们在此介绍用于光
化学解笼的
DMACM 改性 8-硝基-cGMP 的合成和特性。由于 8-硝基-cGMP 的光稳定性有限,因此必须小心谨慎,但完整产品的光释放是很容易实现的。意想不到的是,8-硝基-cGMP 在光照射下会衰变,形成 8-亚硝基
鸟嘌呤。
