  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.

  The present invention relates to a preparation method of a novel vascular leakage blocker with a high yield. The preparation method is easy to react and more productive and economical than the conventional method by using an intermediate that can easily remove impurities generated during the reaction. In addition, the preparation method can produce a novel vascular leakage blocker with a high yield by using a new reagent that has not been previously used in the step of generating an isomer, and is very advantageous in producing a high-quality active pharmaceutical ingredient.
