Biological Activity
IC50: <1 μM (human LOXL2), <10 μM (bovine LOX)[1]
PXS-5505 free base (Compound 33) inhibits the bovine LOX and human LOXL2 activities with IC50 values of <10 μM and <1 μM, respectively[1].
PXS-5505 free base exhibits sustained inhibition of LOXL1 and LOXL2[1].
PXS-5505 free base is less active against SSAO/VAP-1 and MAO-B activities[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
PXS-5505 free base (10 mg/kg; orally; daily for 14 days) reduces kidney fibrosis in unilateral ureteric obstruction (UUO) mice model[1].
PXS-5505 free base (15 mg/kg; orally; daily for 21 days) reduces lung fibrosis in mice[1].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (7.42 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (7.42 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.
