EC50: 0.1 μM (adenylate cyclase, in heart tissues), 1.0 μM (adenylate cyclase, in gill tissues)

Small cardioactive peptide B (SCPB) is a neurally active peptide endogenous to Aplysia . Small cardioactive peptide B (SCPB) possesses cardioexcitatory effects in Aplysia and reported a threshold concentration of 0.01 nM for both native and synthetic Small cardioactive peptide B (SCPB) stimulated effects on the isolated heart. Effects of Small Cardioactive Peptide B (SCPB) on the physiology of the isolated heart and gill preparations from the mollusc Aplysia californica were examined. In addition, the effects of Small Cardioactive Peptide B (SCPB) and FMRFamide (Phe-Met-Arg-Phe-NH2) on adenylate cyclase activity are compared in particulate fractions of heart and gill tissues, respectively. Small Cardioactive Peptide B (SCPB) is found to exert dose-dependent, reversible changes in cardiac activity wh
