Rp-cAMPS 竞争性抑制 cAMP 诱导的 cAMP 依赖性蛋白激酶激活。

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-cAMPS triethylammonium salt 是 cAMP 依赖性蛋白激酶 I 和 II 的竞争性抑制剂，通过阻断 cAMP 诱导的构象转换来抑制 cAMP 诱导的 cAMP 依赖性蛋白激酶 （PKA） 激活。

Rp-cAMPS TEA salt is a cAMP-dependent protein kinase (PKA) activator.

Rp-8-bromo-Cyclic AMPS (Rp-8-bromo-cAMPS) is a cell-permeable cAMP analog that combines an exocyclic sulfur substitution in the equatorial position of the cyclophosphate ring with a bromine substitution in the adenine base of cAMP. It acts as an antagonist of cAMP-dependent protein kinases (PKAs) and is resistant to hydrolysis by cyclic nucleotide phosphodiesterases. Rp-8-bromo-cAMPS more effectively antagonizes cAMP-dependent activation of purified PKA type I from rabbit muscle than PKA type II from bovine heart.

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]

Rp-8-CPT-cAMPS is a powerful and competitive antagonist of cAMP-induced activation of cAMP-dependent protein kinase (PKA) I and II. Acting as a potent cAMP analog, Rp-8-CPT-cAMPS exhibits a preference for site A of RI over site A of RII. Additionally, it favors site B of RII over site B of RI. This compound effectively inhibits cAMP-dependent PKA activation and demonstrates selectivity in binding to specific sites within the protein kinase.

Rp-8-Br-cAMPS 作为PKA的抑制剂，通过与调节亚基的cAMP结合位点相结合，避免了PKA的解离和激活。此外，Rp-8-Br-cAMPS在逆转录病毒感染的小鼠模型中能够增强免疫功能。
