SQ 22,536 Chemical Properties,Usage,Production

Description

SQ 22,536 is an inhibitor of adenylyl cyclase with an IC₅₀ value of 13 μM for inhibition of prostaglandin E₁-stimulated increase in cAMP in intact platelets. It has been used to evaluate adenylyl cyclase activity during iloprost-induced vasorelaxation of isolated pulmonary veins or aorta in several research paradigms, inhibiting cAMP elevation at concentrations of 100-300 μM without effecting relaxation.

Uses

SQ 22,536 was used to study the role of adenylate cyclase in differentiation of PC12 cells and in gap junctional intercellular communication in breast cancer cells.

Definition

ChEBI: A nucleoside analogue that is adenine in which the nitrogen at position 9 has been substituted by a tetrahydrofuran-2-yl group. It is an adenylate cyclase inhibitor.

Biological Activity

Inhibitor of adenylyl cyclase (IC 50 = 1.4 μ M). Inhibits PGE 1 -stimulated increases in cAMP levels in intact human platelets.

Biochem/physiol Actions

SQ 22,536 is an effective inhibitor of not only basal but also prosptaglandin E1-activated adenylate cyclase activities in platelets.1 It reverses hyperalgesia contralaterally and ipsilaterally when injected intramuscularly in rats.2

storage

Store at +4°C
