英文名: GW 405833

描述: GW 405833 (L-768242) 是一种大麻素 2 (CB(2)) 受体选择性激动剂。

动物实验: Baseline mechanical paw withdrawal thresholds were measured in each paw for each animal before performing either PSNL or injecting CFA.?Another predrug baseline was then taken after painful peripheral neuropathy or inflammatory pain was fully established.?GW405833 was administered (i.p.) 30 minutes before evaluation of the impact of drug manipulations on mechanical paw withdrawal thresholds.?Different doses of GW405833 were injected (i.p.) within subjects in the order of vehicle (0), 3, 10, and 30 mg/kg.?Sufficient time was allowed to lapse between each dose to verify that mechanical paw withdrawal thresholds returned to the predrug levels before dose escalation. .?In the groups where CB1 or CB2 antagonists were tested, rimonabant or SR144528 (10 mg/kg i.p.) was administered 20 minutes before GW405833 injection[1].

体内活性: GW405833 (3, 10, and 30 mg/kg i.p.) dose dependently reversed established mechanical allodynia in both pain models in WT mice;?however, the antiallodynic effects of GW405833 were fully preserved in CB2KO mice and absent in CB1KO mice.?Furthermore, the antiallodynic efficacy of GW405833 (30 mg/kg i.p.) was completely blocked by the CB1 antagonist rimonabant (10 mg/kg i.p.) but not by the CB2 antagonist SR144528 (10 mg/kg i.p.).?Thus, the antinociceptive properties of GW405833 are dependent on CB1 receptors.?GW405833 (30 mg/kg i.p.) was also inactive in a tetrad of tests measuring cardinal signs of CB1 activation.?Additionally, unlike rimonabant (10 mg/kg i.p.), GW405833 (10 mg/kg, i.p.) did not act as a CB1 antagonist in vivo to precipitate withdrawal in mice treated chronically with Δ9-tetrahydrocannabinol[1].
