Biological Activity

Targets	CCR2
ln Vitro	In vitro activity: PF-4136309 exhibits potency in human chemotaxis activity (IC50 = 3.9 nM) and in the whole blood assay (IC50 = 19 nM). In mouse and rat chemotaxis assays, its IC50 values are 16 and 2.8 nM, respectively. With IC50 values of 3.3 and 0.5 nM, respectively, PF-4136309 exhibits potent inhibition of CCR2 mediated signaling events, including intracellular calcium mobilization and ERK (extracellular signal-regulated kinase) phosphorylation. With an IC50 of 20 μM, PF-4136309 suppresses the hERG potassium current in the hERG patch clamp assay. With IC50 values greater than 30 μM against the five main CYP isozymes CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4, PF-4136309 is not a cytochrome P450 (CYP) inhibitor. Moreover, at concentrations up to 30 μM, PF-4136309 is not a CYP inducer[1].
ln Vivo	PF-4136309 (2 mg/kg) shows a moderate half-life (2.5 and 2.4 hours) following intravenous administration in both species. When taken orally, PF-4136309 (10 mg/kg) is quickly absorbed, with rats and dogs experiencing peak concentration times (Tmax) of 1.2 and 0.25 hours, respectively. When administering IV and po doses to both species, a comparable half-life is seen. In both species, PF-4136309 exhibits a high degree of oral bioavailability, measuring 78%[1].
ADME/Pharmacokinetics	In vitro ADME (absorption, distribution, metabolism, and excretion) profiling revealed that 17 (INCB8761/PF-4136309) has a moderate permeability across Caco-2 monolayers with a value of 3.1 × 10–6 cm/s. In protein binding, 17 had a free fraction of 23% in human serum. When incubated with human liver microsomes, 17 exhibited a moderate intrinsic clearance, with a half-life (t1/2) of 89 min. When 17 was incubated with human S9 with or without NADPH and the cofactor glutathione, no glutathione adducts were detected. Compound 17 is not a cytochrome P450 (CYP) inhibitor, with IC50 values of >30 μM against five major CYP isozymes CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4. Compound 17 is not a CYP inducer at concentrations up to 30 μM. [1] The pharmacokinetics of 17 (INCB8761/PF-4136309) was assessed in rats and dogs (Table 4). Following iv administration of 17, the total systemic clearance was moderate in rats but low in dogs. The apparent steady-state volume of distribution (Vss) followed the same trend as in clearance, with high Vss in rats and low Vss in dogs. As a result, 17 exhibited a moderate half-life in both species after iv administration (2.5 and 2.4 h). When administered orally, 17 was absorbed rapidly, with peak concentration time (Tmax) at 1.2 h for rats and 0.25 h for dogs. A similar half-life was observed in both species between iv dosing and po dosing. Compound 17 was well absorbed, with an oral bioavailability of 78% in both species.[1]

Additional Infomation	The discovery of a new (S)-3-aminopyrrolidine series of CCR2 antagonists was reported. Structure-activity relationship studies on this new series led to the identification of 17 (INCB8761/PF-4136309) that exhibited potent CCR2 antagonistic activity, high selectivity, weak hERG activity, and an excellent in vitro and in vivo ADMET profile. INCB8761/PF-4136309 has entered human clinical trials.[1]

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
