Rp-8-Br-cAMPS is a lipophilic analog of Rp-cAMPS (sc-24010), demonstrating competitve preferential inhibition of PKA (PKC-alpha). Rp-8-Br-cAMPS is believed to function by occupying cAMP binding sites thus preventing dissociation and activation of the kinase holoenzyme. Rp-8-Br-cAMPS is resistant to mammalian cyclic nucleotide-dependent phosphodiesterases. Rp-8-Br-cAMPS is significantly more lipophilic and membrane permeant compared to Rp-cAMPS (sc-24010) or 8-Br-cAMP.

Thank you for your question. The CAS number shown (129735-00-8) for sc-3539, Rp-8-Br-cAMPS is correct. The Chemical Abstract Society (CAS) will register new CAS numbers to unique chemical substances when needed. It is very common that salt forms and/or hydrate forms of a Chemical are not given separate CAS numbers because in many cases, the different forms do not constitute a unique Chemical.

Rated 5 out of 5 by from MarkovaMarkova, et. al. used a PKA type I inhibitor, RP-8-Br-cAMPS (SCBT catalog # sc-3539) in their study regarding IL-4 signaling in human T cells. They found that RP-8-Br-cAMPS restored relipram down regulated expression of IL-5 mRNA in IL-4 stimulated cells. -SCBT Publication Review
