Bexotegrast is a potent inhibitor of ανβ6 integrin. Bexotegrast can be used for researching fibrosis such as idiopathic pulmonary fibrosis (IPF) and nonspecific interstitial pneumonia (NSIP) (extracted from patent WO2020210404A1, compound 5).

体外研究
Bexotegrass (PLN-74809; 1.82 µM; incubated for 7 days) significantly reduced the expression of type I collagen alpha I (COL1A1) mRNA by 54% in precision cut lung sections (PCLS). Bexotegrass showed a decrease of approximately 50% in Smad2 phosphorylation.
Bexotegrass (1.82 µM; incubation for 3 days) dose dependently reduced Col1a1 mRNA expression in PCLS prepared from fibrotic mouse lungs by up to 71%.
Bexotegrass completely inhibits the adhesion of normal human bronchial epithelial cells to LAP mediated by α v β 6 integrin, with an IC50 of 39.3 nM.
