产品描述： JNJ-7777120 is a potent and selective histamine H4 receptor antagonist (Ki=4.5 nM). JNJ-7777120 effectively blocks histamine-induced migration of mouse tracheal mast cells from connective tissue to epithelial cells. JNJ-7777120 also significantly blocks neutrophil infiltration in a mouse Zymosan-induced peritonitis model. JNJ-7777120 has a good potential to study antipruritic and anti-inflammatory |

体内研究：
JNJ-7777120 shows equipotent against the human, mouse, and rat receptors and exhibits at least 1000-fold selectivity over H1, H2, or H3 receptors. JNJ-7777120 has an oral bioavailability of ~30% in rats and 100% in dogs, with a half-life of ~3 h in both species. JNJ-7777120 (20 mg/kg; s.c.; single daily for 2 days) blocks the histamine-induced migration of tracheal mast cells from the connective tissue toward the epithelium in mice. JNJ-7777120 (10 mg/kg; s.c.; single) significantly blocks neutrophil infiltration in a mouse zymosan-induced peritonitis model. Animal Model: BALB/c mice. Dosage: 20 mg/kg Administration: Subcutaneous injection; single daily for 2 days Result: Blocked histamine induced an increase in the number of mast cells per tracheal section and a significant migration of mast cells towards the tracheal epithelium. Animal Model: Male outbred Swiss albino mice (zymosan-induced peritonitis model). Dosage: 10 mg/kg Administration: Subcutaneous injection; single Result: Led to a statistically significant reduction of neutrophil infiltration. |
