(-)-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].
