Effects of behaviorally active ACTH (4-10) analogue - Semax on rat basal forebrain cholinergic neurons.

Purpose: It is well established that cholinergic neurons of the basal forebrain degenerate in Alzheimer's dementia. Although recent studies were concentrated on screening molecules that might reduce the concomitant cell loss, little is known about therapeutically promising molecules. We studied the effect of Semax (Met-Glu-His-Phe-Pro-Gly-Pro), a behaviorally active adrenocorticotropic hormone (4-10) analogue, on survival of cholinergic basal forebrain neurons in vitro.
