Product Description
BX471 hydrochloride (ZK-811752 hydrochloride) is a potent, selective non-peptide CCR1 antagonist with K i of 1 nM for human CCR1 , and exhibits 250-fold selectivity for CCR1 over CCR2 , CCR5 and CXCR4 .
In Vitro
BX471 is a potent functional antagonist based on its ability to inhibit a number of CCR1-mediated effects including Ca 2+ mobilization, increase in extracellular acidification rate, CD11b expression, and leukocyte migration. BX471 demonstrats a greater than 10,000-fold selectivity for CCR1 compared with 28 G-protein-coupled receptors. BX471 is also able to displace 125 I-MIP-1α/CCL3 binding to mouse CCR1 in a concentration-dependent manner with a K i of 215±46 nM. Increasing concentrations of BX471 inhibits the Ca 2+ transients induced by MIP-1α/CCL3 in both human and mouse CCR1 with IC 50 of 5.8±1 nM and 198±7 nM, respectively. BX471 (0.1-10 μM) shows a dose-dependent inhibition of RANTES-mediated and shear-resistant adhesion on IL-1β-activated microvascular endothelium in shear flow in isolated blood monocytes. BX471 also inhibits the RANTES-mediated adhesion of T lymphocytes to activated endothelium . MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
BX471 (4 mg/kg, p.o. or i.v.) is orally active with a bioavailability of 60% in dogs. Furthermore, BX471 effectively reduces disease in a rat experimental allergic encephalomyelitis model of multiple sclerosis . BX471 (20 mg/kg, s.c.) reaches peak plasma levels of 9 μM by around 30 minutes, and this rapidly declines to approximately 0.4 μM after 2 hours. From 4 to 8 hours the drug plasma levels drops to 0.1 μM or lower. Mice treated with 20 mg/kg of BX471 for 10 days shows a reduction of interstitial CD45 positive leukocytes of approximately 55%. BX471 has a borderline significant effect on the number of CCR5-positive CD8 cells in the peripheral blood. BX471 reduces the amount of FSP1-positive cells by 65% in UUO kidneys as compared with vehicle control. Pretreatment witih BX471 reduces macrophage and neutrophil accumulation in kidney after ischemia-reperfusion injury. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
This compound belongs to the class of organic compounds known as n-phenylureas. These are compounds containing a N-phenylurea moiety, which is structurally characterized by a phenyl group linked to one nitrogen atom of a urea group.
