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
Description
In Vitro
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].

Fibrosis/Collagen Morphometry
Fibrosis and collagen morphometry is based on the quantitative visualization of fibrillar collagen deposition in tissue sections using histochemical stains such as Sirius Red (Picrosirius Red) or Masson's trichrome, followed by image-based or polarization-enhanced analysis to estimate collagen proportional area as a surrogate of extracellular matrix accumulation during fibrotic remodeling. Sirius Red combined with polarized light microscopy enhances detection of collagen fibers due to birefringence properties, enabling more specific visualization of collagen type I and III fibrils compared to conventional bright-field histology, while whole-section or region-restricted digital morphometry reduces field-selection bias in fibrosis assessment. Alternative quantitative approaches include second harmonic generation (SHG) and two-photon excited fluorescence microscopy, which enable label-free detection of fibrillar collagen and have been validated against histological staining and biochemica

Collagen: Sirius Red Staining
Sirius Red or picrosirius red staining is a histochemical method for visualizing collagen-rich extracellular matrix in tissue sections, and collagen fibers are detected as red-stained structures under bright-field microscopy with enhanced birefringence under polarized light. Picrosirius red is useful for assessing total collagen organization, distribution, and fibrosis burden, but polarized color should not be interpreted as a definitive collagen type I versus type III readout because color is affected by fiber orientation, thickness, and packing.

Connective Tissue: Masson's Trichrome/Collagen Trichrome Staining
Masson’s Trichrome (collagen/trichrome staining) is a histological technique that differentially stains tissue compartments using sequential acidic dyes to distinguish collagen from muscle and cytoplasmic components based on dye affinity and tissue permeability differences, enabling visualization of fibrosis and connective tissue architecture in histological sections. The classical formulation typically uses Weigert's iron hematoxylin for nuclear staining, Biebrich scarlet-acid fuchsin for cytoplasm and muscle, and aniline blue (or light green variants) for collagen, producing a characteristic blue/green collagen signal contrasted against red cytoplasm and dark nuclei. The staining principle relies on selective displacement of smaller dye molecules by larger anionic dyes in collagen-rich regions under controlled acidified conditions, which enhances collagen-specific dye retention. This property makes the method widely used for fibrosis assessment in organs such as heart, liver, lung, a
