Description

TAS-301 is a potent and selective constrictive remodeling regulator on renarrowing after balloon overstretch injury of porcine coronary artery. TAS-103 inhibits smooth muscle cell migration and proliferation. TAS-103 inhibits intimal thickening after balloon injury to rat carotid arteries. TAS-301 blocks receptor-operated calcium influx and inhibits rat vascular smooth muscle cell proliferation induced by basic fibroblast growth factor and platelet-derived growth factor. TAS-103 inhibits calcium-dependent signal transduction and cytoskeletal reorganization.

How to use

In Vitro:

TAS-301 (1-10 μM) concentration-dependently inhibits PKC activation and Ca2+ influx, induced by PDGF, with 62.7% inhibition on PKC activation at 10 μM, and reduces PMA-induced AP-1, with 38% and 67.6% inhibition at 3 and 10 μM, respectively. TAS-301 (0.3-3 μM) dose-dependently reduces the migration of cells induced by growth factors (PDGF-BB, IGF-1, HB-EGF). TAS-301 (1-10 μM) also decreases bFGF-induced BrdU incorporation, especially at 3 and 10 μM.

In Vivo:

TAS-301 (3-100 mg/kg, p.o.) dose-dependently reduces the neointimal thickening and I/M ratio and decreases the level of intimal cells in rats 14 days after balloon injury.
