Cơ Chế Tác Dụng :
AT2220 is an experimental, oral therapy for the treatment of Pompe disease and belongs to a class of molecules known as pharmacological chaperones. It is a small molecule designed to act as a pharmacological chaperone that specifically binds, stabilizes, and facilitates the proper folding and trafficking of α-glucosidase (GAA). GAA to the lysosome, where it can perform its normal function. AT2220 has been shown to increase GAA activity in cell lines derived from Pompe patients and in transfected cells expressing misfolded forms of GAA.
AT2220 is designed to act as a pharmacological chaperone by selectively binding to the misfolded enzyme responsible for Pompe disease, Gaa. After binding to the enzyme, it is thought that AT2220 promotes the proper folding, processing, and trafficking of the enzyme from the endoplasmic reticulum to its final destination, the lysosome, the area of the cell where the enzyme does its work. Once it reaches the lysosome, the pharmacological chaperone is displaced, and the enzyme can perform its normal function, which is the breakdown of its natural substrate, glycogen.
Chỉ Định :
Pompe disease, also known as glycogen storage disease type II or acid maltase deficiency, is a relatively rare neuromuscular and lysosomal storage disorder caused by inherited genetic mutations in a key enzyme called α-glucosidase (Gaa).
