生化/生理作用

LIT-927 is an orally active CXCL12 (SDF1) neutraligand (Kd = 267) that selectively neutralizes CXCL12, but not CCL17, CCL22, CCL5, or CCL2 activity in cultures (10 μM LIT-927 against 5 nM chemokine-induced calcium mobilization). LIT-927 reduces eosinophil recruitment in a murine allergic airway hypereosinophilia model in vivo (330 nmol/kg intranasal, 350 nmol/kg ip. or 1400 μmol/kg po.), offering greatly improved oral activity and solubility than Chalcone-4, and exhibiting little side-effects when compared with dexamethasone or CXCR4 antagonist AMD3100.
