Bexotegrast
Based on 3 publication(s) in Google Scholar
Bexotegrast (PLN-74809) is an orally active, potent dual αvβ6/αvβ1 integrin inhibitor with Kd of 5.7 nM and 3.4 nM, respectively. Bexotegrast inhibits αvβ6- and αvβ1-induced TGF-β activation with IC50 values of 29.8 nM and 19.2 nM, respectively. Bexotegrast has antifibrogenic effects and block multiple avenues of TGF-β activation in the fibrotic lung.

Bexotegrast (PLN-74809; 1.82 µM; 7-day incubation) significantly reduces collagen type I alpha I (COL1A1) mRNA expression by 54% in precision-cut lung slices (PCLSs). PLN-74809 shows an approximately 50% reduction in Smad2 phosphorylation[2].
Bexotegrast (1.82 µM; 3-day incubation) dose-dependently reduces Col1a1 mRNA expression in PCLSs prepared from fibrotic mouse lungs by up to 71%[2].
Bexotegrast fully inhibits αvβ6 integrin-mediated adhesion to LAP by normal human bronchial epithelial cells with an IC50 of 39.3 nM[2].

Immunofluorescence staining for KRT17 protein in co-cultures of SFTPCI73T mutant iAT2s and iLM. The results showed that treatment of co-cultures of SFTPCI73T mutant iAT2s and iLM for 7 days with either SB525334 (1 μM; 1 week) or Bexotegrast (2 μM; 1 week), compared to vehicle-treated controls, abolished KRT17 protein expression in co-cultured SFTPCI73T mutant iAT2s. Scale bars = 100 μm. Hoechst = nuclei.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
