C₁₃H₁₆N₅O₉P; MW 417.3; λ_max 252 nm; ε 13500; purity > 97% HPLC for mixture of axial and equatorial isomer. Membrane-permeant precursor of the second messenger cyclic GMP. Metabolic activation by esterases releases the polar active analogue which is trapped inside the cell. In contrast to other membrane-permeant and PDE-resistant cGMP analogues, cGMP-AM yields a transient increase (pulse) of cGMP. Especially suitable for external triggering of cGMP-regulated phosphodiesterases (PDE II, III & V) where most cGMP analogues are not accepted. Detailed technical information available.

Biolog also offers Phosphate tris(acetoxymethyl)ester (PO₄-AM₃, Cat. No. P 030) which is recommended as control reagent in nucleotide-AM ester applications.
