Leukadherin 1

Pricing Availability Delivery Time Qty
Cat.No. 4921 - Leukadherin 1 | C22H15NO4S2 | CAS No. 344897-95-6
Description: Allosteric activator of CD11b/CD18
Chemical Name: 4-[(5-[[4-Oxo-3-(phenylmethyl)-2-thioxo-5-thiazolidinylidene]methyl]-2-furanyl]benzoic acid
Purity: ≥98% (HPLC)

Biological Activity

Allosteric activator of CD11b/CD18. Increases CD11b/CD18-dependent cell adhesion to fibrinogen (EC50 = 4 μM). Decreases leukocyte motility and transendothelial migration; reduces inflammation. Also activates complement receptor 3 (CR3), and promotes CR3-dependent leukocyte adhesion to fibrinogen-coated surfaces.
