Droxidopa (Synonyms: L-DOPS; DOPS; SM5688)

Cat. No.: HY-13458 Purity: 98.04%
Handling Instructions

Droxidopa(L-DOPS) is a potent, orally active norepinephrine precursor. Droxidopa increases standing blood pressure, ameliorates symptoms of orthostatic hypotension and improves standing ability. Droxidopa has the potential for the research of neurogenic orthostatic hypotension (nOH) and alternative ADHD (attention deficit hyperactivity disorder).

Description

Droxidopa(L-DOPS) is a potent, orally active norepinephrine precursor. Droxidopa increases standing blood pressure, ameliorates symptoms of orthostatic hypotension and improves standing ability. Droxidopa has the potential for the research of neurogenic orthostatic hypotension (nOH) and alternative ADHD (attention deficit hyperactivity disorder)[1][2][3][4].

In Vivo

Droxidopa (200 mg/kg;i.p.) alters dopamine neuron and prefrontal cortex activity and improves attention-deficit/hyperactivity disorder-like behaviors in rats[2]. Droxidopa (10, 20 mg/kg; i.p.) significantly increases the paw withdrawal latency and inhibits mechanical hypersensitivity to thermal stimulation in 6-OHDA-lesioned rats at the 5th week after surgery[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: 250-380g male Sprague-Dawley rats[2]
Dosage: 200 mg/kg (10 mg/kg, i.p. benserazide was given to the animals at 20 or 30 min prior to L-DOPS injection)
Administration: I.p.
Result: Significantly decreased hyperactivity of BZ-pretreated SHR/NCrl at 30 (P < 0.01) and 40 min (P < 0.05) post-injection, improved inattention-like behavior of SHR/NCrl, and ameliorated impulsive-like behavior of SHR/NCrl and Wistar rats.
