Steviol (Standard) is the analytical standard of Steviol (HY-N2057). This product is intended for research and analytical applications. Steviol is the main metabolite of steviol glycosides and an inhibitor of AQP2/CFTR. Steviol slows down the growth of renal cysts by inhibiting the activity of CFTR, reducing the expression of AQP2, and promoting the degradation of AQP2 and CFTR. Steviol can be used in the research of polycystic kidney disease[1].
