20120245110 | VASCULAR LEAKAGE INHIBITOR - The present disclosure relates to a novel vascular leakage inhibitor. The novel vascular leakage inhibitor of the present disclosure inhibits the apoptosis of vascular endothelial cells, inhibits the formation of actin stress fibers induced by VEGF, enhances the cortical actin ring structure, and improves the stability of the tight junctions (TJs) between vascular cells, thereby inhibiting vascular leakage. The vascular leakage inhibitor of the present disclosure has the activity of not only reducing vascular permeability but also recovering the integrity of damaged blood vessels. Accordingly, the vascular leakage inhibitor of the present disclosure can prevent or treat various diseases caused by vascular leakage. Since the vascular leakage inhibitor of the present disclosure is synthesized from commercially available or easily synthesizable cholesterols, it has remarkably superior feasibility of commercial synthesis. | 09-27-2012 |
20140378399 | NOVEL VASCULAR LEAKAGEAGE INHIBITOR - The present disclosure relates to a novel vascular leakage inhibitor. The novel vascular leakage inhibitor of the present invention inhibits the apoptosis of vascular endothelial cells, inhibits the formation of actin stress fibers induced by VEGF, and enhances the cortical actin ring structure, thereby inhibiting vascular leakage. Accordingly, the vascular leakage inhibitor of the present invention can prevent or treat various diseases caused by vascular leakage. Since the vascular leakage inhibitor of the present invention is synthesized from commercially available or easily synthesizable pregnenolones, it has remarkably superior feasibility of commercial synthesis. | 12-25-2014 |
