生物活性

製品説明 Droxidopa (L-DOPS) is a psychoactive drug and acts as a prodrug to the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline).
in vitro Droxidopa is a pro-drug which has a structure similar to noradrenaline, but with a carboxyl group. Droxidopa can be administered orally, unlike noradrenaline, and after absorption is converted by the enzyme dopa decarboxylase into noradrenaline thus increasing levels of the neurotransmitter which is identical to endogenous noradrenaline. [1] Droxidopa is well tolerated. [2] Droxidopa could exert its pressor effect in three different ways: a) as a central stimulator of sympathetic activity; b) as a peripheral sympathetic neurotransmitter; c) as a circulating hormone. Droxidopa taken alone increases standing blood pressure. [3] Droxidopa can also cross the blood–brain barrier (BBB) where it is converted to norepinephrine and epinephrine from within the brain. [4]
in vivo The acute administration of droxidopa in PVL and BDL rats caused a significant and maintained increase in arterial pressure and mesenteric arterial resistance, with a significant decrease of mesenteric arterial and portal blood flow, without changing portal pressure and renal blood flow. Droxidopa-treated rats also showed a decreased ratio of p-eNOS/eNOS and p-AKT/AKT and increased activity of RhoK in SMA[5].
特徴 An artificial amino acid.
