Difenamizole (20170-20-1, 20170-21-2)
Difenamizole (INN) (brand name Pasalin; former developmental code name AP-14) is a nonsteroidal anti-inflammatory drug (NSAID) and analgesic of the pyrazolone group related to metamizole. It has monoaminergic properties, including inhibition of monoamine oxidase, augmentation of pargyline-induced elevation of striatal dopamine levels, inhibition of K+-induced striatal dopamine release, and inhibition of the reuptake of dopamine.
Fezolamine (Win-41,528-2) is a drug which was investigated by Sterling Drug as an antidepressant in the 1980s. The isomeric N,N-dimethyl-4,5-diphenyl-1H-pyrazole-1-propanamine was completely inactive in the primary antidepressant screens. It acts as a serotonin, norepinephrine, and dopamine reuptake inhibitor, with 3- to 4-fold preference for the former neurotransmitter.
Brofaromine (proposed brand name Consonar) is a reversible inhibitor of monoamine oxidase A (RIMA) discovered by Ciba-Geigy. The compound was primarily researched in the treatment of depression and anxiety but its development was dropped before it was brought to market. Brofaromine also acts as a serotonin reuptake inhibitor, and its dual pharmacologic effects offered promise in the treatment of a wide spectrum of depressed patients while producing less severe anticholinergic side effects in comparison with older standard drugs like the tricyclic antidepressants.
para-Chloroamphetamine (64-12-0, 2275-84-5)
Ly123362 · Ly 123362 · p-Chloroamphetamine
para-Chloroamphetamine (PCA), also known as 4-chloroamphetamine (4-CA), is a substituted amphetamine and monoamine releaser similar to MDMA, but with substantially higher neurotoxicity, thought to be due to the unrestrained release of both serotonin and dopamine by a metabolite. It is used as a neurotoxin by neurobiologists to selectively kill serotonergic neurons for research purposes, in the same way that 6-hydroxydopamine is used to kill dopaminergic neurons. However, the effects of the compound on experimental animals appear less encouraging.
beta-methylphenethylamine · beta-methylphenylethylamine · BMPEA compound
β-Methylphenethylamine (β-Me-PEA, BMPEA), or 1-amino-2-phenylpropane, is an organic compound of the phenethylamine class, and a positional isomer of the drug amphetamine, with which it shares some properties. In particular, both amphetamine and β-methylphenethylamine are human TAAR1 agonists. In appearance, it is a colorless or yellowish liquid.
