rp-camps sodium

Rp-cAMPS sodium 是一种cAMP的硫代磷酸酯类似物，是一种蛋白激酶 A 抑制剂，也是具有膜渗透性的 cAMP 拮抗剂，通过阻断 cAMP 诱导的构象转变来抑制 cAMP 依赖性蛋白激酶，可用于研究心血管疾病。

Rp-8-CPT-cAMP is a structural combination of the lipophilic and non-hydrolyzable cAMP analogs, 8-CPT-cyclic AMP and Rp-cyclic AMPS .[1] It functions as a site-selective inhibitor of protein kinase A (PKA) type I and II, with preference towards site A of type I and site B of type II.2 By occupying cAMP binding sites at the regulatory subunit of PKA, Rp-8-CPT-cAMP prevents the kinase holoenzyme from dissociative activation.[2],[3]
