产品介绍
JNJ-7777120是一种强效的和具有选择性的组胺 H4受体拮抗剂 (Ki=4.5 nM)。JNJ-7777120 能有效阻断组胺诱导的小鼠气管肥大细胞从结缔组织向上皮细胞的迁移。JNJ-7777120 还能在小鼠 Zymosan 诱导的腹膜炎模型中显著阻断中性粒细胞的浸润。JNJ-7777120 具有研究抗瘙痒和抗炎的较好潜力。
生物活性

JNJ-7777120 is a potent and selectivehistamineH4receptorantagonist (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[1][2].

体外研究
(In Vitro)

JNJ-7777120 (0, 10, 100, 1000 nM; ~6 h) shows functional antagonism of the human and mouse histamine H4 receptors in SK-N-MC cells[1].
JNJ-7777120 (10 μM; 10 min) blocks histamine-induced chemotaxis and calcium influx in mouse bone marrow-derived mast cells[1].
JNJ7777120 (30-100 μM; 30 min) inhibits dose-dependently the production of thymus and activation-regulated chemokine/CCL17 and macrophage-derived chemokine/CCL22 from antigen-stimulated BMMC[2].

Cell Viability Assay[1]

Cell Line:SK-N-MC cells (expressing the human or mouse histamine H4 receptor)
Concentration:0, 10, 100, 1000 nM
Incubation Time:~6 h
Result:Exhibited antagonistic effect on human and mouse histamine H4 receptors.

Immunofluorescence[1]

Cell Line:Mouse mast cells
Concentration:10 μM
Incubation Time:10 min
Result:Exhibited a very potent antagonistic effect on the H4 receptor in primary cells.

Cell Viability Assay[1]

Cell Line:BMMC
Concentration:30-100 μM
Incubation Time:30 min
Result:Significantly inhibited the production of TARC (thymus and activation-regulated chemokine) and MDC (macrophage-derived chemokine).
体内研究
(In Vivo)

JNJ-7777120 shows equipotent against the human, mouse, and rat receptors and exhibits at least 1000-fold selectivity over H1, H2, or H3receptors[1].
JNJ-7777120 has an oral bioavailability of ~30% in rats and 100% in dogs, with a half-life of ~3 h in both species[1].
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[1].
JNJ-7777120 (10 mg/kg; s.c.; single) significantly blocks neutrophil infiltration in a mouse zymosan-induced peritonitis model[1].

Animal Model:BALB/c mice[1].
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)[1].
Dosage:10 mg/kg
Administration:Subcutaneous injection; single
Result:Led to a statistically significant reduction of neutrophil infiltration.
