JNJ-39758979是一种选择性的、高亲和力的、可口服的组胺 H4 受体拮抗剂，具有抗炎和止痒作用，对人、小鼠和猴子的组胺 H4 受体的Ki值分别为 12.5、5.3 和 25 nM。它对组胺诱导的 cAMP 抑制作用具有拮抗作用，pA2 为 7.9。

JNJ-39758979 is a selective and high-affinity histamine H4 receptor antagonist (Kis: 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 is metabolically stable (t1/2 >120 min) when incubated in vitro with human, rat, dog, or monkey liver microsomes. JNJ 39758979 is a selective and high-affinity histamine H4 receptor antagonist (Ki: 12.5 nM versus the human H4 receptor). In transfected cells, functionally antagonizes histamine-induced cAMP inhibition ( pA2: 7.9). 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 H3 receptors [1].

JNJ-39758979 (2 mg/kg; i.v.) treatment shows that the Vss, AUC, CL and t1/2 were 19.9 L/kg, 1.4 μM*h, 2.2 L/h, and 2.1 hours, respectively. JNJ-39758979 (10 mg/kg; p.o.) treatment displays that the Cmax, t1/2, and F values are 0.3 μM, 7.5 hours, and 36%, respectively [1].
