| 描述 | [Leu5]-Enkephalin is a pentapeptide with morphine like properties. [Leu5]-Enkephalin is a five amino acid endogenous peptide that acts as an agonist at opioid receptors. [Leu5]-Enkephalin is a pentapeptides with morphine like properties, naturally present in mammalian brain[1]. The antinociceptive effect of [Leu5]enkephalin administered intrathecally on the tail-flick test was increased more than 100-fold under i.t. pretreatment with three peptidase inhibitors. The antinociceptive effect produced by [Leu5]enkephalin in rats pretreated with any single peptidase inhibitor increased antinociception compared to that with saline[2]. (D-Ala2, D-leu5)-enkephalin (1 mg/kg) treatment also markedly enhanced morphine analgesia[3]. [D-Ala2, Met5]enkephalinamide and [D-Ala2, D-Leu5]enkephalin as well as [Met5]- and [Leu5]enkephalin increased contractility in a concentration-dependent manner. The enkephalin-induced maximal contractile effects were 28% and 30% above control, with EC50 values of 0.53 and 0.17 microM for [D-Ala2, Met5]enkephalinamide and [D-Ala2, D-Leu5]enkephalin, respectively. Enkephalins exert a direct positive inotropic effect on cultured heart cells, increasing contractile state via specific opiate receptors[4]. |
