dihydroxyphenylalanine and Morphine Abuse

dihydroxyphenylalanine has been researched along with Morphine Abuse in 5 studies

Dihydroxyphenylalanine: A beta-hydroxylated derivative of phenylalanine. The D-form of dihydroxyphenylalanine has less physiologic activity than the L-form and is commonly used experimentally to determine whether the pharmacological effects of LEVODOPA are stereospecific.
dopa : A hydroxyphenylalanine carrying hydroxy substituents at positions 3 and 4 of the benzene ring.

Research Excerpts

ExcerptRelevanceReference
"Pretreatment with norharman (20 mg/kg) or LSL 60101 (20 mg/kg) (30 min before naloxone) fully prevented the stimulatory effect of opiate withdrawal on DOPA synthesis."1.33High-affinity binding of beta-carbolines to imidazoline I2B receptors and MAO-A in rat tissues: norharman blocks the effect of morphine withdrawal on DOPA/noradrenaline synthesis in the brain. ( Asensio, VJ; Esteban, S; García-Sevilla, JA; Miralles, A; Moranta, D; Sastre-Coll, A, 2005)
"In summary, we conclude that morphine addiction is associated with supersensitivity of 5-HT1A serotonin receptors and alpha2-adrenoceptors (autoreceptors and heteroreceptors) that modulate the synthesis of monoamines in brain."1.31Supersensitivity of 5-HT1A autoreceptors and alpha2-adrenoceptors regulating monoamine synthesis in the brain of morphine-dependent rats. ( Esteban, S; García-Sevilla, JA; Sastre-Coll, A, 2002)
