  • Title: Effects of atropine and azaprophen on matching and detection in rhesus monkeys.
    Author: Genovese RF, Elsmore TF.
    Journal: Pharmacol Biochem Behav; 1989 Feb; 32(2):495-8. PubMed ID: 2727010.
    Abstract:
    The effects of the anticholinergic atropine and azaprophen, a novel, conformationally restricted analog of atropine, were examined in rhesus monkeys using delayed match-to-sample and detection tasks. Both compounds (0.01-0.32 mg/kg) produced dose-dependent decreases in the rate of responding under both tasks. Drug effects on the match-to-sample task correlated with drug effects on the detection task. Both compounds produced decreases in the percentage of correct responses on the match-to-sample task when choice trials occurred 4 or 16 sec, but not 0.01 sec, following sample presentation. Doses of atropine and azaprophen decreasing accuracy on the match-to-sample task also decreased the number of responses on the task. In general, atropine was slightly more potent than azaprophen on both tasks. These results further characterize azaprophen's anticholinergic effects.
