JNJ 10191584 maleate is a highly selective histamine H4 receptor silent antagonist; binds with high affinity to the human H4 receptor (Ki = 26 nM). > 540-fold selective over the H3 receptor (Ki = 14.1 μM). Inhibits mast cell and eosinophil chemotaxis in vitro with IC50 values of 138 and 530 nM respectively. Orally active in vivo.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
