What is YS 49?
Biological Activity
YS-49 is an activator of PI3K/Akt, a downstream target of RhoA, and reduces RhoA/PTEN activation in 3-methylcholine-treated cells. YS-49 inhibits angiotensin II (Ang II)-stimulated VSMC proliferation by inducing heme oxygenase (HO-1). YS-49 is an isoquinoline compound alkaloid with strong positive inotropic effects due to its ability to activate cardiac β-adrenoceptors.
in vitro
YS-49 (1-100 μM; 18 hours; RAVSMC and RAW 264.7 cells) concentration-dependently inhibits the accumulation of nitrite in both RAVSMC and RAW 264.7 exposed to lipopolysaccharide (LPS) plus INF-γ, with IC 50 values of 22 μM and 30 μM, respectively.
YS-49 (10-100 μM; 18 hours; RAVSMC and RAW 264.7 cells) suppresses iNOS gene expression induced by LPS and/or cytokines in RAVSMC and RAW 264.7 cells at the transcriptional level.
