Description: | JNJ-5207852 is a selective and potent histamine H3 receptor (H3R) antagonist, with pKis of 8.9, 9.24 for rat and human H3R, respectively. |
Target: | H3 receptor:8.9 (pKi, for rat) H3 receptor:9.24 (pKi, for human) |
In Vivo: | In mice and rats, JNJ-5207852 (1-10mg/kg s.c.) increases time spent awake and decreases REM sleep and slow-wave sleep, but fails to have an effect on wakefulness or sleep in H3 receptor knockout mice. No rebound hypersomnolence, as measured by slow-wave delta power, is observed. The wake promoting effects of this H3 receptor antagonist are not associated with hypermotility. A 4-week daily treatment of mice with JNJ-5207852 (10 mg/kg i.p.) does not lead to a change in body weight, possibly due to the compound being a neutral antagonist at the H3 receptor. JNJ-5207852 is extensively absorbed after oral administration and reaches high brain levels[1]. |
Animal Administration: | Rats[1] Male, Sprague-Dawley rats weighing 282-334 g are used. The animals are individually housed with free access to food and water. To assure that there are no pre-existing group differences in activity levels prior to the initiation of treatment, LMA is monitored and recorded during a 2 h habituation period. Following the 2 h habituation period, testing is briefly interrupted and animals are s.c. injected with either saline (1 mL/kg; n=6), JNJ-5207852 (3, 10, 30 mg/kg; n=6-7 animals/group) or Damphetamine (0.75 mg/kg; n=6). Testing is immediately resumed following the compound injection[1]. |
