stimulant Stimulants (also known as central nervous system stimulants, or psychostimulants, or colloquially as uppers) are a class of drugs that increase alertness. They are used for various purposes, such as enhancing attention, motivation, cognition, ...

drug developed by American Cyanamid Company in the 1960s. The drug is related to other drugs such as pemoline and thozalinone. It displayed a favorable therapeutic index and margin of safety in comparison to pemoline and other N-lower-alkyl-substituted pemoline derivatives. The patents concluded that cyclazodone possessed properties efficacious in reducing fatigue and as a potential anorectic. Structural congeners of pemoline have been described as "excitants with unique properties distinguishing them from the sympathomimetic amines" whilst displaying less stimulatory activity and toxicity compared to amphetamine. It is included under the World Anti-Doping Agency prohibited list.

Safety

Cyclazodone has not been evaluated by the United States Food and Drug Administration for use in humans as a nootropic, anorectic, or stimulant and thus safety information is lacking. However, in studies relating to the therapeutic uses of cyclazodone, it was noted that it exhibited less cardiotoxic and hepatotoxic effects than D-amphetamine in studies on mice.

Synthesis

α-Chlorophenylacetyl chloride (1) and 1-cyclopropylurea (2) react to give the amide (3). The heterocycle cyclazodone is formed on threatment of this with sodium ethoxide.Najer, H. et al, Bull. Soc. Chim. Fr., 1963, 1810.
