Biological target:
Bexotegrast is a potent inhibitor of ανβ6 integrin.
In vitro activity:
The potency and selectivity of small-molecule αv integrin inhibitors were profiled using human integrin ligand-binding assays (Table 1). PLN-74809 inhibited αvβ6- and αvβ1-induced TGF-β activation with IC50 values of 29.8 nM and 19.2 nM, respectively.
Reference: Respir Res. 2021 Oct 19;22(1):265. https://pubmed.ncbi.nlm.nih.gov/34666752/
In vivo activity:
Due to a scarcity of explanted tissue from patients with IPF, the bleomycin mouse model of pulmonary fibrosis was utilized as a supplemental source of fibrotic lung tissue for PCLS experiments. Following 3 days of treatment, dual αvβ6/αvβ1 inhibitor PLN-74809 dose-dependently reduced Col1a1 mRNA expression in PCLSs prepared from fibrotic mouse lungs by up to 71%, with a significant reduction observed at concentrations as low as 16 nM (Additional file 1: Fig. S2; P < 0.05).

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
