Axial isomer, for the corresponding  isomeric mixture please inquire. DMACM-caged 8-Br-cGMP is an only weakly fluorescent, caged precursor of 8-bromo cyclic cGMP, which upon irradiation, releases both 8-Br-cGMP and a strongly fluorescent coumarin analogue. High lipophilicity and membrane permeability, thus only limited solubility in aqueous systems. Detailed technical information available. For similar approach please compare: Hagen et al., J. Photochem. Photobiol. B: Biol., 53 (1999).
