Alpha methyltryptamine (AMT) is a tryptamine (indole ethylamine) derivative, which was developed in the 1960's by Upjohn with the intention for use as an antidepressant. It was used in Russia under the trade name Indopan for the treatment of Bipolar disorder and some form of depression, but currently not being produced because of serious side effects. In the 1990's, alpha-methyltryptamine became regulated as a Schedule I controlled substance in the United States. Pharmacologically, AMT has high affinity for the serotonin (5-HT) transporter, a number of 5-HT receptors, and potently inhibits reuptake of monoamines dopamine, 5-HT, and norepinephrine reuptake. AMT is also a monoamine oxidase A inhibitor that conceivably could contribute to its pharmacological effect and this drug also the most potent inhibitor of semicarbazide-sensitive amine oxidase (SSAO).

Tetrahydropalmatine is a tetrahydroprotoberberine isoquinoline alkaloid that is a primary active constituent of herbal preparations containing plant species of the genera Stephania and Corydalis. The levo isomer of THP (L-THP) appears to contribute to many of the therapeutic effects of these preparations. The pharmacological profile of L-THP, which includes antagonism of dopamine D1 and D2 receptors and actions at dopamine D3, suggests that it may have utility for treating addiction. Clinical trials where L-THP was used for the treatment of cocaine and heroin addiction have promising results. The clinical trial is planned for the treatment of schizophrenia. L-Tetrahydropalmatine is recorded in the Chinese pharmacopoeia.

Targets:
Dihydrexidine, a novel full efficacy D1 dopamine receptor agonist. Dihydrexidine was shown to stimulate cyclic AMP synthesis just as well or better than dopamine. It was the first dopamine D1 receptor agonist that had potent antiparkinsonian activity in a primate model of Parkinson's disease. Dihydrexidine produces hypothermia. Dihydrexidine has been shown to alleviate cognitive deficits or enhance cognitive performance in a number of animal models of cognition. It is under investigation for the improving the cognitive and working memory deficits in schizophrenia and schizotypal disorder.

Conditions:
Salvinorin A has been reported to be the most potent naturally occurring hallucinogen, with an effective dose in humans in the 200- to the 1,000-μg range when smoked; it has been reported to induce an intense hallucinatory experience in humans, with a typical duration of action being several minutes to an hour or so. Salvinorin A is a highly selective agonist of the kappa-opioid receptor (KOR) with few off-target effects. It is a potent and selective dilator of the cerebral vasculature, exhibits rapid penetration through the blood-brain barrier, has potent anti-inflammatory properties, and has the ability to preserve neurovascular unit integrity. As such, salvinorin A is an ideal compound for the prevention and treatment of cerebral vasospasm following subarachnoid hemorrhage.

Mephedrone (4-methylmethcathinone) is a β-ketoamphetamine belonging to the family of synthetic cathinones, an emerging class of designer drugs known for their hallucinogenic and psychostimulant properties as well as for their abuse potential. Mephedrone is a stimulant of dopamine (DA) release and blocks its reuptake through its interaction with the dopamine transporter. Furthermore, it has some affinity for various 5-hydroxytryptamine (5-HT) receptor subtypes. Neurotoxic effect of mephedrone on 5-HT and DA systems remains controversial. Although some studies in animal models reported no damage to DA nerve endings in the striatum and no significant changes in brain monoamine levels, some others suggested a rapid reduction in 5-HT and DA transporter function. Persistent serotonergic deficits were observed after binge like treatment in a warm environment and in both serotonergic and dopaminergic nerve endings at high ambient temperature. Oxidative stress cytotoxicity and an increase in frontal cortex lipid peroxidation were also reported. Despite the re-classification of mephedrone as a Class B restricted substance by the United Kingdom and restrictive legislation by the United States, international policy regarding mephedrone control is still developing and interest in synthetic amphetamine-like drugs could drive the development of future mephedrone analogues.
