PTI-428（Cat No.:I019406） is a small molecule compound that functions as a cystic fibrosis transmembrane conductance regulator (CFTR) amplifier. It has been developed as a potential therapeutic for cystic fibrosis (CF), a genetic disorder characterized by defective CFTR protein function. PTI-428 works by enhancing CFTR protein synthesis, stability, and trafficking to the cell surface, leading to increased CFTR activity.
