Description

(-)-Apomorphine (hydrochloride hydrate) acts as a potent dopamine receptor agonist with a broad spectrum on all D1- and D2-like receptors (D1, D2S, D2L, D3, D4, D5) [1]. (-)-Apomorphine (hydrochloride hydrate) is extremely lipophilic and can cross the blood–brain barrier freely[2]. (-)-Apomorphine (hydrochloride hydrate) is the oldest dopaminergic drug available for Parkinson’s disease[3][4]. (-)-Apomorphine (hydrochloride hydrate) is a highly potent antioxidant and free radical scavenger with a neuroprotective effect[5].

(-)-Apomorphine (hydrochloride hydrate) at concentrations of higher than 2 x10-5M treatment dramatically reduced the growth-stimulatory effect of retinal pigment epithelium (RPE) cells on the scleral chondrocytes[6]. (-)-Apomorphine (hydrochloride hydrate) exhibits potent relaxant effects on rat corpus cavernosum tissues in vitro, particularly on phenylephrine-induced contractions, without altering cyclic nucleotides[7].

(-)-Apomorphine (hydrochloride hydrate) induced erections in awake rats, peaking at 300nmol/kg, but had no effect on basal or nerve-stimulated cavernous pressure in anesthetized rats[7]. (-)-Apomorphine (hydrochloride hydrate) (20mg/kg, i.p) administration to rats with normal 4-day estrous cycles reduced serum prolactin levels during diestrus and prevented the proestrous rise in serum prolactin[8].

实验参考方法

Cell experiment [1]:

Cell lines

Chondrocytes

Preparation Method

Chondrocytes with or without co-cultured retinal pigment epithelium (RPE) cells were treated with 2 x10-5M (-)-Apomorphine (hydrochloride hydrate) for 3 days. Then the number of chondrocytes was then counted using a Coulter counter to calculate the proliferation rate.

Reaction Conditions

2 x10-5M, 3d

Applications

(-)-Apomorphine (hydrochloride hydrate) treatment dramatically reduced the growth-stimulatory effect of RPE cells on the scleral chondrocytes.
Animal experiment [2]:

Animal models

Sprague-Dawley rats

Preparation Method

Rats were treated with Chlorpromazine (CPZ), followed by an intraperitoneal injection of (-)-Apomorphine (hydrochloride hydrate) 1 hour later. Then rats were sacrificed and their blood was collected from individual rats, allowed to clot over ice, then serum was removed and assayed for prolactin (PRL) by a double antibody radioimmunoassay.

Dosage form

20mg/kg, 1h, i.p.

Applications

(-)-Apomorphine (hydrochloride hydrate) treatment significantly lowered the elevated levels of prolactin (PRL) produced by Chlorpromazine (CPZ) pretreatment of diestrous rats.
