highly purified, typical fluorescent impurities removed. For other salt forms of 8-CPT-cAMP please inquire. Lipophilic activator of both cAMP- and cGMP-dependent protein kinase and of Epac. Higher activation potential compared to cAMP; excellent cell membrane permeability, improved phosphodiesterase stability and high site selectivity preferring site B of cAK type II. Detailed technical information and selected references available. Reference: Geiger et al.: Proc. Natl. Acad. Sci. USA, 89, 1031 - 1035 (1992). Caution: Despite its name this analogue is not selective, but activates cGMP-dependent protein kinase as well! In addition, it increases the basal cGMP level by inhibition of PDE V (Murray et al., Biochem. Pharmacol., 44, 2303 - 2306 (1992)).
