Cyclazodone: Difference between revisions

>Scrumptious
m The validity of concerns regarding hepatotoxicity with pemoline is still under debate, and thus, I adjusted the wording to maintain a neutral tone of speech. Please refer to the article "Pemoline-associated hepatic failure: A critical analysis of the literature" for further information.
>Scrumptious
m Correction of the stated potency, which was in reference to fenozolone (2-monoethylamino), not pemoline, and adjustment of the wording

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 more potent than that of pemoline and 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 name="GuidicelliPatent">{{Citation | vauthors=((Guidicelli, D.

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}}
