Cyclazodone is an approximately 3x - 5x more potent N-cyclopropyl derivative of [[pemoline]]. Pemoline is considered to be [[dopamine|dopaminergic]], but its precise method of action has not been fully determined.<ref>"Cylert (Pemoline)" (PDF). FDA. December 2002.</ref> Pemoline has minimal affinity for [[noradrenaline]] receptors and thus has minimal sympathomimetic side effects compared with typical dopaminergic central nervous system stimulants such as methylphenidate and [[Isomer|dextro]]-amphetamine.

According to patents filed by the inventors, cyclazodone exhibited central nervous system stimulating properties and anorexigenic properties much more potent than those of pemoline, and more potent than those of various other N-lower-alkyl-substituted pemoline derivatives. At the time cyclazodone also offered a much more favorable therapeutic index and margin of safety than pemoline and other N-lower-alkyl-substituted pemoline derivatives.<ref>Val De Marne, Don Pierre R.

In animal models, cyclazodone exhibits central nervous system stimulant and antidepressant efficacy and potency at least equal to that of [[Isomer|dextro]]-amphetamine.

===Pharmacodynamics===
Cyclazodone is an [[amphetamine]]-like [[agonist]] of the Trace Amine Associated Receptor 1 (TAAR1), which is a key regulator of common and trace brain monoamines such as [[dopamine]], [[serotonin]] and [[noradrenaline]].<ref>The Emerging Role of Trace Amine Associated Receptor 1 in the Functional Regulation of Monoamine Transporters and Dopaminergic Activity (PubMed.gov / NCBI) | http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3005101/</ref><ref>Drug banks amphetamine targets | http://www.drugbank.ca/drugs/DB00182#targets</ref><ref>TA1 receptor | http://www.iuphar-db.org/DATABASE/ObjectDisplayForward?objectId=364</ref> The agonism of this set of receptors results in the release of increased concentrations of [[dopamine]], [[serotonin]] and [[noradrenaline]] in the [[synaptic cleft]]. This leads to [[Thought acceleration|cognitive]] and [[Stimulation|physical stimulation]] within the user.

The toxicity and long-term health effects of recreational cyclazodone use do not seem to have been studied in any scientific context and the [[Toxicity::exact toxic dosage is unknown]]. This is because cyclazodone has a very limited history of human usage.

Another compound related in structure, [[4-methylaminorex]], is associated with pulmonary hypertension<ref>https://www.ncbi.nlm.nih.gov/pubmed/11083709</ref>; though, it is reported to induce far stronger stimulation than that of cyclazodone.

In rodents and primates, sufficiently high doses of monoamine [[releasing agent|releasing agents]] cause dopaminergic neurotoxicity, or damage to dopamine neurons, which is characterized by reduced transporter and receptor function. There is no evidence that [[releasing agent]]s are directly neurotoxic in humans. However, large doses of [[releasing agent]]s may cause indirect neurotoxicity as a result of increased oxidative stress from reactive oxygen species and autoxidation of dopamine.{{citation needed}}
