CHEMICAL (ACHIRAL)
Solypertine (WIN-18413-2) is an antiadrenergic drug. Solypertine selectively blocked the conditioned avoidance response in rats. Solypertine potentiated hexobarbitone sleeping time, caused hypothermia and afforded protection from amphetamine toxicity inaggregated mice.

Quinelorane is an octahydropyrimido[4,5-g]quinolone derivative patented by American pharmaceutical company Eli Lilly and Co. as for the treatment anxiety, Parkinson's syndrome, depression, and hypertension. Quinelorane acts as an agonist of dopamine agonist for the D2 and D3 receptors. In preclinical studies Quinelorane (IM) treatment produced dose-dependent effects on male sexual responding. Penile erections and masturbation were markedly facilitated following treatment with either 2.5 or 5 micrograms/kg quinelorane. Higher doses of quinelorane (10 and 25 micrograms/kg) generally did not further augment sexual responding but rather resulted in a return in sexual responding to control vehicle levels. Quinelorane had a biphasic effect on yawning behavior of the monkeys with low doses (2.5 and 5 micrograms/kg) facilitating yawning and high doses (25 micrograms/kg) inhibiting yawning.

Oxidopamine (6-Hydroxydopamine) is an antagonist of the neurotransmitter dopamine with potential antineoplastic activity. 6-Hydroxydopamine (6-HOD) can be taken up by selective adrenergic terminals, thereby causing acute degeneration of adrenergic terminals that leads to depletion of norepinephrine, and of dopamine in the dopamine-sensitive sites. This agent is auto-oxidated at physiological pH that leads to the formation of reactive free radicals, thereby leading to cytotoxicity in neural cells. 6-Hydroxydopamine is often used to induce CNS and sympathetic neural lesions that model aging and various nervous disorders in animal systems. The growth of C-1300 neuroblastoma was markedly slowed in 6-hydroxydopamine-treated mice. The growth of the A-10 breast adenocarcinoma was also significantly retarded in 6-hydroxydopamine-treated mice but the growth of B-16 melanoma was not affected.

Fonturacetam, also known as Phenylpiracetam, is marketed in Russia as Carphedon and Phenotropil. It is one of the first ever nootropic drugs and originally discovered in Russia. Fonturacetam acts on most neurotransmitter systems and has been used for its cognitive and physical enhancing properties, and also as an antidepressant.

Quinpirole (LY 171,555) is a psychoactive drug and research chemical which acts as a selective D2 and D3 receptor agonist. Quinpirole is the most widely used D2 agonist in in vivo and in vitro studies. Specific quinpirole binding in rat brain was saturable, and dependent on temperature, membrane concentration, sodium concentration and guanine nucleotides. Saturation analysis revealed high affinity binding characteristics (KD = 2.3 nM) which were confirmed by association-dissociation kinetics. The regional distribution of [3H]quinpirole binding sites roughly paralleled the distribution of [3H]spiperone binding sites, with greatest densities present in the striatum, nucleus accumbens and olfactory tubercles. A variety of drugs, most notably monoamine oxidase inhibitors (MAOls), inhibit the binding of [3H]quinpirole, but not [3H]spiperone or [3H](-)N-n-Propylnorapomorphine, in rat striatal membranes by a mechanism that does not appear to involve the enzymatic activity of MAO. Clinically antidepressant MAOIs exhibited selectivity between sites labeled by [3H]quinpirole and [3H]spiperone as did a number of structurally related propargylamines and N-acylethylenediamine derivatives and other drugs such as debrisoquin and phenylbiguanide. Quinpirole has been shown to increase locomotion and sniffing behavior in mice and induces compulsive behavior symptomatic of obsessive compulsive disorder in rats.

Lergotrile is an ergot alkaloid clinically effective in the treatment of Parkinson’s disease. The in vivo dopaminergic effects of lergotrile are similar to those produced by the direct acting dopaminergic agonists apomorphine or L-DOPA. Like apomorphine or L-DOPA, lergotrile decreases prolactin secretion, produces stereotyped behavior in intact rats, and causes contralateral rotation in rats with uniIateral 6-hydroxydopamine lesions of substantia nigra. However, unlike apomorphine or L-DOPA, lergotrile does not activate dopamine sensitive adenylate cyclase in vitro. Side effects of lergotrile included exacerbation of hallucinations, dyskinesias, hypotension, and alterations in liver function tests. Although lergotrile, when added to levodopa, has a definite antiparkinsonian effect, the incidence of adverse effects, particularly hepatotoxicity, makes it unlikely that this ergot alkaloid will become widely available for the treatment of Parkinson’s disease.

Fluperlapine is dibenzazepine chemically and pharmacologically similar to clozapine. Fluperlapine had no cataleptogenic effect and did not inhibit the apomorphine- and d-amphetamine-induced stereotypes. Fluperlapine is fairly effective neuroleptic drug with a fast-acting antipsychotic affect. The effects in movement disorders imply that fluperlapine is less liable than traditional neuroleptics to induce acute extrapyramidal side effects and tardive dyskinesia and is particularly beneficial in the treatment of patients vulnerable to neurological side-effects. It was demonstrated efficacy in the treatment of a variety of medical conditions including schizophrenia, psychosis associated with Parkinson's disease and dystonia. It has the capacity for producing life-threatening agranulocytosis.

Pentiapine is a dopamine release inhibitor. It is a tranquiliser. Pentiapine produces a dose-dependent decrease in spontaneous motor activity and blocks the morphineinduced hyperactivity. Moreover, this drug in itself has no effect on place conditioning but blocks the acquisition of morphine-induced conditioned place preference.
