N2  - The novel adamantane derivative APICA (N-(adamantan-1-yl)-1-pentyl-1H-indole-3-carboxamide) was recently identified as a cannabinomimetic indole of abuse. Despite its novel structure, APICA recalls cannabinomimetic indoles, such as representative member JWH-018. In present study, the effects of APICA (1-3mg/kg, i.p.) were tested in C57BL/6J mice, in the Tetrad task which includes the assessment of: body temperature; locomotor activity and behavioural reactivity; nociception; motor coordination; declarative memory. Furthermore, pre-treatment with the CB1 antagonist AM251 (3mg/kg, i.p.) or the CB2 antagonist AM630 (3mg/kg, i.p.) was carried out to characterize APICA activity. Our results show that APICA was able to dose-dependently decrease locomotor activity and behavioural reactivity in the open field, whereas only the highest dose was able to induce hypothermia, analgesia, motor incoordination and recognition memory impairment, with respect to vehicle (p<0.01; p<0.001). The pretreatment with the CB1 antagonist AM251 elicited an increase in body temperature, total distance travelled in the open field, latency to fall down in the Rotarod, and a decrease in tail flick latency (p<0.05; p<0.01). On the other hand, pretreatment with AM630 did not induced significant differences on APICA effects. This study supports preliminary reports on APICA cannabinomimetic properties, extending its detrimental effects on cognitive function. Moreover, these properties can be attributed to the CB1 receptor activity, indicating APICA as a selective CB1 receptor agonist.<p />  <p>Language: en</p>
