H4 Receptor Antagonists (10):

Cat. No. Product Name Effect Purity
  • HY-13508
    JNJ-7777120
    		Antagonist 99.85%
    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.
  • HY-101189
    JNJ-39758979
    		Antagonist 99.71%
    JNJ-39758979 is a selective, orally active, and high-affinity histamine H4 receptor antagonist with Kis of 12.5, 5.3, and 25 nM for human, mouse, and monkey histamine H4 receptor, respectively. JNJ-39758979 functionally antagonizes histamine-induced cAMP inhibition with a pA2 of 7.9 in transfected cells. JNJ-39758979 shows good anti-inflammatory and antipruritic activity.
  • HY-16756
    Toreforant
    		Antagonist 99.82%
    Toreforant is a potent and selective histamine H4 receptor (H4R) antagonist, with a Ki at the human receptor of 8.4 nM.
