Cyclic GMP: Guanosine cyclic 3',5'-(hydrogen phosphate). A guanine nucleotide containing one phosphate group which is esterified to the sugar moiety in both the 3'- and 5'-positions. It is a cellular regulatory agent and has been described as a second messenger. Its levels increase in response to a variety of hormones, including acetylcholine, insulin, and oxytocin and it has been found to activate specific protein kinases. (From Merck Index, 11th ed). 3',5'-cyclic GMP : A 3',5'-cyclic purine nucleotide in which the purine nucleobase is specified as guanidine. | 4.08 | 15 | 0 | 3',5'-cyclic purine nucleotide;

8-bromocyclic gmp
8-bromo-3',5'-cyclic GMP : A 3',5'-cyclic purine nucleotide that is 3',5'-cyclic GMP bearing an additional bromo substituent at position 8 on the guanine ring. A membrane permeable cGMP analogue that activates protein kinase G (PKG). It is 4.3-fold more potent than cGMP in activating PKG1alpha and promotes relaxation of tracheal and vascular smooth muscle tissue in vitro. | 2.69 | 3 | 0 | 3',5'-cyclic purine nucleotide;
