| Uses | CCR4-351 is an orally active, potent and selective CCR4 antagonist. CCR4-351, featuring a novel piperidinyl-azetidine motif, has IC50s of 22 nM and 50 nM in the calcium flux and CTX assay. CCR4-351 has antitumor activity[1]. | | Biological Activity | CCR4 antagonist 3 is an orally active, potent and selective CCR4 antagonist. CCR4 antagonist 3, featuring a novel piperidinyl-azetidine motif, has IC50s of 22 nM and 50 nM in the calcium flux and CTX assay. CCR4 antagonist 3 has antitumor activity[1].
CCR4 antagonist 3 (compound 38) shows no activity in a CYP450 induction assay[1]. CCR4 antagonist 3 inhibits the migration of mouse iTreg cells with an IC50 of 39 nM, while the IC50 in human iTreg cells is 33 nM[1].
CCR4 antagonist 3 (compound 38; 50 mg/kg; PO; daily; for 40 days) significantly reduces the tumor growth[1]. CCR4 antagonist 3 (0.5 mg/kg; IV) has low clearance (CL=10.2 mL/min/kg), medium volume of distribution (Vss=5.2 L/kg), a T1/2 of 6.9 h, and good bioavailability (%F = 29) of oral dosing in mouse[1]. CCR4 antagonist 3 has low clearance (CL=7.3 mL/min/kg), a half-life of 12.7 hr, and is 44% bioavailable in dog. CCR4 antagonist 3 has low clearance (CL=3.7 mL/min/kg), a long terminal half-life (10.7 hr), and good bioavailability (%F = 41) in cynomolgus monkey[1]. | | in vivo | CCR4-351 (compound 38; 50 mg/kg; PO; daily; for 40 days) significantly reduces the tumor growth[1].

|
| Animal Model: | Rat and mouse[1] | | Dosage: | 0.5 mg/kg of IV; 2 mg/kg of PO | | Administration: | IV or PO | | Result: | Possessed medium clearance (CL=47.6 mL/min/kg) and was 49% bioavailable upon oral dosing in rat.
Had low clearance (CL=10.2 mL/min/kg), medium volume of distribution (Vss=5.2 L/kg), a T1/2 of 6.9 h, and good bioavailability (%F = 29) of oral dosing in mouse.
