8-Chloro-cAMP is a cAMP analogue that induces growth arrest, and modulates cAMP-dependent PKA activity. 8-Chloro-cAMP has anticancer activity[1].
8-Chloro-cAMP markedly inhibits vascular smooth muscle cell (VSMC) proliferation in vitro, reduces protein kinase A (PKA) RIα subunit expression, and induces PKA RIIβ subunit expression[1].
In rat bearing balloon injury, 8-Chloro-cAMP (12 mg/kg) reduces, in a dose-dependent manner, neointimal area and neointima/media ratio after balloon injury. 8-Chloro-cAMP shows a reduction of proliferative activity of VSMCs in vivo[1].
