Application

BX471 has been used in chemotaxis assay to study the responses of HEK293 cells expressing human C-C motif chemokine receptor 1 (CCR1) to CC motif ligand 3 (CCL3)-induced cell migration. It has also been used as a CCR1 inhibitor to assess the effects of CCR1 on the migration and epithelial-mesenchymal transition (EMT).

Biochem/physiol Actions

BX471 blocks CCR1 and downregulates the mRNA expression of ICAM-1, P-selectin and E-selectin. It decreases the inflammatory responses in sepsis, prevents monocyte recruitment in inflammation sites in rheumatoid arthritis patients and inhibits interstitial leukocyte recruitment and fibrosis in mouse model of lupus nephritis.
BX471 is an orally active, CCR-1 specific antagonist. It displaces the endogenous CCR-1 ligands MIP-1a, RANTES and MCP-3 (Ki range 1-5 nM). BX471 inhibits CCR-1 effects in leukocytes, including calcium mobilization and migration.
