Biological Activity

Description JNJ-7777120 is the first potent and selective non-imidazole histamine H4 receptor antagonist with Ki of 4.5 nM, exhibits >1000-fold selectivity over the other histamin receptors.
Targets
Histamine H4 receptor [1]
4.5 nM(Ki)
In vitro
In vitro JNJ 7777120 binds with high affinity to the H4 receptor and has a greater than 1000-fold selectivity over the other histamine receptors. JNJ 7777120 is a selective and potent H4 receptor antagonist with little or no affinity for over 50 other targets. [2]
In Vivo
In vivo 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 blocks histamine-induced chemotaxis and calcium influx in mouse bone marrow-derived mast cells. JNJ 7777120 can block the histamine-induced migration of tracheal mast cells from the connective tissue toward the epithelium in mice. JNJ 7777120 significantly blocks neutrophil infiltration in a mouse zymosan-induced peritonitis model. [2]
Animal Research Animal Models Female BALB/c mice
Dosages 200 mg/kg
Administration P.O.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
