For other salt forms please inquire. Sp-2'-O-MB-cAMPS is a lipophilic precursor of Sp-cAMPS
(Cat. No. A 003), a PDE-resistant activator of protein kinase A. During metabolic activation by esterases Sp-cAMPS and butyrate are released. Caution: Butyrate was shown to have distinct biological effects! Significantly more lipophilic and membrane-permeant compared to Sp-cAMPS. Detailed technical information available.
