N-(4-diethylamino-2-butynyl)-succinimide, or DKJ-21, is a muscarinic receptor antagonist with a high degree of selectivity for the central nervous system. In the present study of 6 rats maintained under a fixed-interval 50-sec schedule of food reinforcement, atropine and methylatropine reduced responding in a dose dependent manner, while DKJ-21 had little or no effect. Our findings suggest that the suppression caused by atropine and methylatropine may be the result of the dry mouth induced by… CONTINUE READING
