| Description | PF-0463481 is safe and well-tolerated and has the potential for the study of diabetic nephropathy. PF-0463481 is an effective and orally active dual CCR2/CCR5 antagonist. It also has comparable human and rodent CCR2 potency (rat IC50=20.8 nM). PF-0463481 shows 10-20 fold less rodent CCR5 potency (rat IC50=470 nM). |
| In vivo | PF-04634817 (p.o.; 30 mg/kg; once daily; 31 days intervention (weeks 2-15 after Streptozotocin)) intervention at the onset of diabetes (week 2) has no impact on the fasting blood glucose levels in diabetic Nos3-/- 221 mice. Early intervention with PF-04634817 induces an additional increase in glycated hemoglobin (HbA1c) levels. The development of diabetes causes a marked increase in the levels of glycated haemoglobin (HbA1c) in Nos3-/- mice [1]. |
