| 产品描述: | Sp-cAMPS sodium salt, a cAMP analog, is potent activator of cAMP-dependent PKA I and PKA II. Sp-cAMPS sodium salt is also a potent, competitive phosphodiesterase (PDE3A) inhibitor with a Ki of 47.6 µM. Sp-cAMPS sodium salt binds the PDE10 GAF domain with an EC50 of 40 μM. |
| 靶点: |
PKA I;PKA II;PDE3A:47.6 μM (Ki);PDE10 GAF domain:50 μM (EC50) |
| 体外研究: |
在慢性饮酒 (CAC) 小鼠中,将 Sp-cAMPS (1 µg/µL) sodium salt 直接注入前额叶皮层可显着改善孤僻动物,或损害水生动物的工作记忆表现[5]。 |
| 体内研究: |
Sp-cAMPS sodium salt 是腺苷环状 3',5'-硫代磷酸酯的刺激性非对映异构体,其处理肝细胞,模拟胰高血糖素所见的反应。Sp-cAMPS sodium salt 可以模拟胰高血糖素刺激的 Ca2+ 水平升高。 |
