sodium,(4aR,6R,7R,7aS)-6-[6-amino-8-(4-chlorophenyl)sulfanylpurin-9-yl]-2-oxido-2-sulfanylidene-4a,6,7,7a-tetrahydro-4H-furo[3,2-d][1,3,2]dioxaphosphinin-7-ol

Biological Activity

[Description]:

Rp-8-CPT-cAMPS, a cAMP analog, is a potent and competitive antagonist of cAMP-induced activation of cAMP-dependent PKA I and II. Rp-8-CPT-cAMPS preferentially selects site A of RI compares to site A of RII and site B of RII compares to site B of RI[1][2].

[In Vitro]

Rp-8-CPT-cAMPS (100 μM; 15 min) blocks phosphorylation of VASP by 6-Bnz-cAMP and largely reduces VASP phosphorylation by forskolin and fenoterol[2]. Rp-8-CPT-cAMPS (100 μM; 30 min) reduces GTP-loading of Rap1 by both 8-pCPT-2'-O-Me-cAMP and 6-Bnz-cAMP[2]. Rp-8-CPT-cAMPS (100 μM; 30 min) largely diminishes the augmentation of bradykinin-induced IL-8 release by the PKA activator 6-Bnz-cAMP and the Epac activator 8-pCPT-2'-O-Me-cAMP[2]. Rp-8-CPT-cAMPS (10 μM) inhibits the endothelium-dependent and -independent relaxation which induced by Venom in pre-contracted rat mesenteric artery rings[3].

Mediation of hippocampal mossy fiber long-term potentiation by cyclic AMP.

Science 265 , 1878, (1994)

Repetitive activation of hippocampal mossy fibers evokes a long-term potentiation (LTP) of synaptic responses in pyramidal cells in the CA3 region that is independent of N-methyl-D-aspartate receptor ...
