Activité biologique

Description

In Vitro

TLR9-IN-3 (Compound 20) has high metabolic stability in human and mouse liver microsomes (half-life > 120 min) but low stability in rat liver microsomes (half-life 3 min), and exhibits favorable passive permeability in PAMPA and Caco-2 assays^[1].
TLR9-IN-3 (0-25 μM) shows no cytotoxicity in A549, RAMOS, and THP-1 cell lines at concentrations up to 25 μM^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

TLR9-IN-3 (compound 20) (1-10 mg/kg; p.o.; QD; 2 days) exhibits statistically significant inhibition of pro-inflammatory and fibrogenic markers in a Bleomycin (HY-108345)-induced mouse lung injury model, with confirmed target engagement at 10 mg/kg^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
