Description

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[1][2].

In Vitro

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].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (4.22 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (4.22 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

  • Protocol 1

    Add each solvent one by one:  PBS

    Solubility: 12.5 mg/mL (25.38 mM); Clear solution; Need ultrasonic and warming and heat to 60°C

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
