| Description | Sp-8-CPT-cAMPS is a powerful and specific cAMP analog that activates cAMP-dependent protein kinase A (PKA I and PKA II) selectively and effectively. It exhibits a 153-fold preference for site A of RI over site A of RII, and a 59-fold preference for site B of RII over site B of RI. |
| In vitro | Sp-8-CPT-cAMPS (100 μM; 24 h) enhances the IL-1β-stimulated nitrite release, and increases the release ofnitrite by vascular smooth muscle cells by 3 fold in the absence of IL-1β in vascular smooth muscle cells[2]. Sp-8-CPT-cAMPS (100 μM; 24 h) increases IL-1β-induced expression of iNOS protein in rat aortic smooth muscle cells[2]. Sp-8-CPT-cAMPS (10?μM; 30?min) exhibits anti-spasmogenic activity on ACh-induced tension development in guinea-pig trachealis[3]. |
