Application of FAK (focal adhesion kinase) inhibitor in treatment of autosomal dominant polycystic kidney disease

The invention proves, through the application of an MDCK (Madin-Darby canine kidney cells) vesicular model, that an FAK (focal adhesion kinase) inhibitor can inhibit the generation and growth of vesicles, can determine intrarenal pharmacological activity of the FAK inhibitor through an in-vitro embryonal vesicular model, and can inhibit the progress of intrarenal vesicles significantly. The invention further proves finally, in a polycystic renal mouse model, that the FAK inhibitor can also inhibit the progress of vesicles in vivo, while the in-vitro and in-vivo vesicular inhibitory actions arein dose-effect relationship. The FAK inhibitor never affects the activity of renal cells; it is indicated that the ability of the FAK inhibitor to polycystic kidney is irrelevant to its cytotoxicity,and that the FAK inhibitor can regulate intracellular signal pathways, which may be one of its important mechanisms to inhibit the progress of renal vesicles. The FAK inhibitor is VS4718 which is suitable for treating autosomal dominant polycystic kidney disease.
