title: Dipeptides delay the onset of morphine withdrawal in the mouse.
abstract: The effect of dipeptides was studied on naloxone-precipitated morphine withdrawal in the mouse. In accordance with previous data, s.c. treatment with Z-prolyl-D-leucine delayed the onset of withdrawal jumpings . Replacement of L-proline by L-glutamate or L-pyroglutamate resulted in dipeptides which were more potent in morphine withdrawal than was Z-prolyl-D-leucine.
