ST-1006, a potent histamine H4 receptor agonist (pKi: 7.94), exhibits significant anti-inflammatory and anti-pruritic effects. It is also a potent inducer of basophil migration.

Lidocaine, an amide local anesthetic, has anti-inflammatory properties in vitro and in vivo, possibly due to an attenuation of pro-inflammatory cytokines.

JNJ-5207852 is a novel, non-imidazole histamine H3 receptor antagonist, with high affinity at the rat (pKi=8.9) and human (pKi=9.24) H3 receptor. JNJ-5207852 is a potent dibasic amine antagonist that binds potently to rat H3 receptors (Ki=1.2?nm), and has good brain penetration. In ex vivo binding studies in mice, the compound had an ED50 of 0.13?mg?kg?1, subcutaneously.
