title: Beta-Endorphin. Opiate receptor-binding activity of synthetic analogs modified in the enkephalin segment in rat brain membrane and neuroblastoma x glioma hybrid cell.
abstract: The potency of a series of synthetic analogs of beta-endorphin in inhibiting binding of [3H2-Tyr27]-beta h-endorphin to either rat brain membranes or neuroblastoma x glioma hybrid cells (NG108-15) has been determined and compared with the previously determined analgesic potency. There is a very good correlation between inhibitory potency in membranes and cells, but the correlation between analgesic potency and inhibitory potency in either membranes or cells is not as good.
