Sp-cAMPS sodium salt 作为 cAMP 类似物,是一种依赖 cAMP 的PKA I 和PKA II 的有效激活剂。Sp-cAMPS sodium salt 还是一种有效的竞争性磷酸二酯酶 (PDE3A) 抑制剂,Ki 为 47.6 μM。Sp-cAMPS sodium salt 结合PDE10 GAF 结构域,EC50为 40 μM 。
Sp-8-CPT-cAMPS is a powerful and specific cAMP analog that activates cAMP-dependent protein kinase A (PKA I and PKA II) selectively and effectively. It exhibits a 153-fold preference for site A of RI over site A of RII, and a 59-fold preference for site B of RII over site B of RI.
