Description General description A cell-permeable quinazolinone containing a non-nucleoside compound that acts as a potent, selective inhibitor of adenylyl cyclase (AC) type V isoform (IC50 = 8.3 µM, 132 µM and 1.7 mM for type V, III and II, respectively) in the presence of Gsα GTPγS-Forskolin. Displays ~210-fold greater selectivity for type V over the type II isoform. The inhibition is non-competitive with respect to ATP and Forskolin. Regulates the AC catalytic activity in heart and lung tissues. A cell-permeable, non-nucleoside compound that acts as a potent, and selective inhibitor of adenylyl cyclase (AC) type V (IC50 = 8.3 µM, 132 µM and 1.7 mM for type V, III and II, respectively) in the presence of G5α GTPγS-Forskolin. Displays ~210-fold greater selectivity for type V over the type II isoform. The inhibition is non-competitive with respect to ATP and Forskolin. Reported to regulate AC catalytic activity in heart and lung tissues. Packaging 5, 25 mg in Plastic ampoule Biochem/physiol Actions Cell permeable: yes Primary Target Adenylate cyclase (AC) type V isoform Product does not compete with ATP. Reversible: no Target IC50: 8.3 µM, 132 µM and 1.7 mM for type V, III and II, of adenylyl cyclase (AC), respectively, in the presence of Gsα GTPγS-Forskolin Packaging Packaged under inert gas Warning Toxicity: Standard Handling (A) Reconstitution Following reconstitution, aliquot and freeze (-20°C).
