Preparation Note
The solubility of the methylxanthines is low, but can be enhanced by the formation of complexes (usually 1:1) with a wide variety of compounds such as ethylenediamine (to form aminophylline). The formation of complex double salts (caffeine and sodium benzoate) or true salts (like choline theophyllinate, and oxtriphylline) also improves aqueous solubility. These salts or complexes dissociate to yield the parent methylxanthines when dissolved in biological fluids and should not be confused with covalently modified derivatives such asdyphylline (1,3-dimethyl-7-(2,3-dihydroxypropyl)-xanthine).

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.
