Abstract
In rats, the β- endorphin fragment, 6–17 (des-enkephalin-γ-endorphin, DEγE), dose-dependently antagonized the reduction of the rate of locomotion and rearing induced by small doses of apomorphine. Structure-activity studies revealed that the active moiety of γ-endorphin fragments with respect to counteracting apomorphine-induced behavioural changes resides in the fragment 6–17. The influence
