J-113863 is a potent and selectiveCCR1(CD18)antagonist withIC₅₀values of 0.9 nM and 5.8 nM for human and mouseCCR1receptors, respectively. J-113863 is also a potent antagonist of the humanCCR3(IC₅₀of 0.58 nM) , but a weak antagonist of the mouseCCR3(IC₅₀of 460 nM). J-113863 is inactive againstCCR2,CCR4andCCR5, as well as the LTB4 or TNF-α receptors. Anti-inflammatory effect^[1][2][3].

Modified Vaccinia virus Ankara (MVA) but not MVA and vaccinia virus (VACV) infected MH-S cells increase the expression of the CXCR2 acting chemokine CXCL2. MH-S cells constitutively produce CCL2 and CCR1 acting chemokines CCL3, CCL5 and CCL9. Consequently, supernatants of mock treated and virus infected MH-S cells induce chemotaxis of murine promyelocyte MPRO cells and human monocytic THP-1 cells at the same level. However, supernatants of MVA infected MH-S cells significantly increase chemotaxis of the CCR2 deficient human monocytic cell line U-937. Chemotaxis of all above cell types is inhibited by J-113863^[1].

J-113863 (3-10 mg/kg; intraperitoneal injection; once daily; for 11 days; DBA-1 male mice) treatment improves paw inflammation and joint damage, and dramatically decreases cell infiltration into joints in arthritic mice^[2].
