ligands for the ccr1 receptor (mip-1α and rantes) have been implicated in plenty of chronic inflammatory diseases, most notably multiple sclerosis and rheumatoid arthritis. bx 513 is a novel non-peptide ccr1 receptor antagonists. | [in vitro]
bx 513 has been shown to have at least 200-fold selectivity for ccr1 inhibition over other human 7-tm receptors, including other chemokine receptors. in addition, data obtained from in-vitro functional assays demonstrated the functional antagonism of bx 513 and structurally related analogues against the ccr1 receptor in a dose-dependent manner [1]. bx 513 also showed concentration-dependent inhibition of mip-1α-induced extracellular acidification and ca2+ mobilization demonstrating functional antagonism. when given alone, the compound did not elicit any responses, suggesting the absence of intrinsic agonist activity. bx 513 inhibited mip-1α- and rantes-induced migration in peripheral blood cells in a dose-responsive manner. selectivity testing against a panel of 7 transmembrane domain receptors indicated that bx 513 is inactive on a number of receptors at concentrations up to 10 μm [2]. | [storage]
