生物活性 | JNJ-39758979 is a selective, orally active, and high-affinityhistamineH4receptorantagonist withKis of 12.5, 5.3, and 25 nM for human, mouse, and monkey histamineH4receptor, 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[1][2]. | ||||||||||||||||

体外研究 (In Vitro) | JNJ 39758979 is a selective, high-affinity histamine H4receptor antagonist with a Kiof 12.5 nM versus the human H4receptor and functionally antagonizes histamine-induced cAMP inhibition with a pA2 of 7.9 in transfected cells. At the mouse H4R, the Ki=5.3 nM and the pA2=8.3. At the monkey H4R, the Ki=25 nM and the pA2=7.5. The affinity for the rat (Ki=188 nM, pA2 = 7.2) and guinea pig H4R (Ki=306 nM) is moderate, and JNJ 39758979 has little if any affinity for the dog H4R (Ki≥10 μM). The compound is highly selective for H4R, as it exhibits low affinity for the H1, H2, and H3receptors[1]. | ||||||||||||||||
体内研究 (In Vivo) | JNJ-39758979 (10 mg/kg; p.o.) treatment shows that the Cmax, t1/2and F values are 0.3 μM, 7.5 hours, and 36%, respectively[1].
