摘要：
1. The analogs of adenosine d- and l-phenylisopropyladenosine (d- and l-PIA) and chloroadenosine (CADO) induced analgesia in mice (hot-plate test). 2. The antinociceptive effects of the three adenosine agonists were antagonized by caffeine but were unaffected by naloxone. 3. Morphine-induced antinociception was increased by pretreatment with adenosine agonists. 4. Whereas CADO significantly attenuated the induction of morphine tolerance, d- and l-PIA did not affect the process. © 1990.
