Vanzacaftor
Based on 5 publication(s) in Google Scholar
Vanzacaftor (VX-121) is an orally active noval corrector of Cystic fibrosis transmembrane conductance regulator (CFTR). Vanzacaftor improves processing and trafficking of CFTR protein as well as increases chloride transport in triple combined with Tezacaftor (HY-15448) and Deutivacaftor. Vanzacaftor-Tezacaftor-Deutivacaftor is safe and well tolerated, improving lung function, respiratory symptoms, and CFTR function with cystic fibrosis, which is promising for research in the field of cystic fibrosis diseases.

Biological Activity
Vanzacaftor (0-10 μM) stimulates K+ secretion at low micromolar concentrations in human bronchial epithelial cells (HBEs), which is inhibited by Paxilline (HY-N6778) with an EC50 of 4.4 μM [2]. Vanzacaftor (1 μM, 5 μM, 10 μM) significantly potentiates αBKCa current density, which is blocked by Paxilline (HY-N6778) in HEK cells[2]. Vanzacaftor (5 μM) reduces action potential firing frequency and alters neuronal excitability in a primary hippocampal neuron[2].
