一般說明
8-溴鸟苷水合物3′,5′-环磷酸腺苷是环鸟苷酸3′:5′-单磷酸(cGMP)的细胞可透过性cGMP类似物。它是一种脂溶性类似物,用于基于cGMP的心肌细胞收缩研究。
應用
使用8-溴鸟苷水合物3′,5′-环磷酸钠盐:
- 作为环鸟苷酸3′:5′-单磷酸(cGMP)激动剂用于视网膜神经节轴突塌陷测定(10)
- 作为反应缓冲液的组成部分,用于重组蛋白激酶的体外激酶活性测定(PKG)(11)
- 作为环核苷酸类似物,用于诱导人胚肾细胞中环化核苷酸门控通道(CNGA和CNGC)表达(12)
生化/生理作用
与cGMP相比,8-溴鸟苷水合物3′,5′-环磷酸腺苷对磷酸二酯酶的水解作用具有更强的抵抗性。激活cGMP依赖性蛋白激酶。它减缓或抑制气管平滑肌细胞内钙振荡对乙酰胆碱的反应。8-溴鸟苷水合物3′,5′-环磷酸钠盐模仿一氧化氮生成药物的效果。它调节生物周期节律,增加视网膜神经脉冲。眼内8-溴鸟苷水合物3′,5′--环磷酸腺苷可能有利于非-R-型光受体的转导。
细胞渗透性 cGMP 类似物比 cGMP 对磷酸二酯酶水解有更大的抵抗力。激活 cGMP 依赖性蛋白激酶。减缓或抑制乙酰胆碱引起的气管平滑肌细胞内钙振荡。据报告,其可模拟一氧化氮生成药物的作用。

Patients born with congenital heart defects frequently encounter arrhythmias due to defects in the ventricular conduction system (VCS) development. Although recent studies identified transcriptional networks essential for the heart development, there is scant information on the mechanisms regulating VCS development.
