Name: Adenosine cyclophosphate Other names: Adenosine 3′,5′-cyclic monophosphate, 3′,5′-Cyclic AMP, cAMP CAS: 60-92-4 INCI Name: Adenosine cyclic phosyphate EC Number: 200-492-9 Molecular Weight: 329.21 Empirical Formula: C10H12N5O6P Standards: Chinese Pharmacopoeia Adenosine cyclophosphate is an important second messenger that is linked in many systems to neurotransmitter- or hormone-induced receptor stimulation. The cAMP/PKA signaling pathway has been shown to inhibit cell proliferation, induce differentiation and lead to apoptosis. Application Adenosine cyclophosphate has been used: As cell culture medium supplement in embryonic spinal neurons As a component of ringer solution for perfusion studies To induce neuroendocrine differentiation in human lung cancer cell lines Adenosine cyclophosphate can also be used as a cosmetic ingredient, its function is skin conditioning.
