SB 290157 trifluoroacetate

Key Product Details

Product Description

SB 290157 trifluoroacetate is a potent C3a receptor antagonist (IC₅₀ values are 27 - 30 nM for C3a-induced Ca²⁺ mobilization in vitro and ex vivo). Inhibits C3a-induced chemotaxis in human mast cell line. Also inhibits tau hyperphosphorylation in vitro. Displays anti-inflammatory effects in animal models of airway inflammation and arthritis. Also inhibits glucose-induced insulin secretion and ATP production from ex vivo human and mouse pancreatic islets. Also exhibits C3a receptor agonist activity.
