CHEMICAL (ACHIRAL)
Targets:
Histamine is a depressor amine derived by enzymatic decarboxylation of histidine. It is a powerful stimulant of gastric secretion, a constrictor of bronchial smooth muscle, a vasodilator, and a centrally acting neurotransmitter. Phosphate salt of jis...
JNJ-39758979 is a histamine H4 receptor antagonist which clinical development for asthma and atopic dermatitis was halted during phase II because of the observation of idiosyncratic drug-induced agranulocytosis in two subjects.
Toreforant (JNJ-38518168) is an orally active, selective histamine H4 receptor antagonist. Toreforant was investigated as an agent for the treatment of active rheumatoid arthritis. While some improvement in rheumatoid arthritis signs/symptoms through...
