生物活性
Rp-cAMPS，一种 cAMP 的类似物，是一种 cAMP 诱导的 PKA I 和 PKA II 活化 (Ki 分别为 12.5 µM 和 4.5 µM) 的有效的，竞争性拮抗剂。Rp-cAMPS 耐磷酸二酯酶水解。靶点
Ki: 6.05 µM (PKA I) and 9.75 µM (PKA II)
体外研究
A membrane-permeable competitive cAMP antagonist (Rp-cAMPS) that blocks PKA activation by binding to the regulatory subunits without dissociating the kinase holoenzyme also inhibits synaptic plasticity but has no effect on normal synaptic transmission.
体内研究
Rp-cAMPS (10 μM, 15 min) decreases the monosynaptic EPSCs evoked at the PB-CeLC and BLA-CeLC synapses in slices from arthritic rats but not in control neurons from normal animals. The inhibitory effect of Rp-cAMPS is significant compared to predrug (ACSF) control values obtained in the same neurons.
