Reduction of amygdaloid kindled seizures by an analog of ACTH/MSH.

A behaviorally potent analog of ACTH/MSH(4-9), ORG-2766, markedly reduces both physiologic and behavioral components of convulsive seizures in an animal model of epilepsy--the amygdaloid kindled rat. We believe that such non-endocrine analogs of ACTH/MSH fragments may be clinically useful anticonvulsants, particularly in chronic applications, provided that their permeation of the blood-brain barrier can be improved.
