ABSTRACT:
A novel class of substances of N-acyl-prolyldipeptides, which possess psychotropic activity and particularly facilitate learning and memory are described. The N-acyl-prolyldipeptides of the invention have the formula: ##STR1## wherein R.sup.1 =(C.sub.4 -C.sub.5) alkyl, cycloalkyl, aralkyl, or aryl; R.sup.2 =H.sub.1 (C.sub.1 -C.sub.4) alkyl, carbamidoalkyl, or carbalkoxyalkyl; R.sup.3 =NH.sub.2, NH(alkyl), N(alkyl).sub.2, OH, or alkoxy; and n=0-3, preferably 0-2.
