The affinities (Ki) of mesocarb at the human monoamine transportersin vitro have been reported to be 8.3nM for the dopamine transporter (DAT), 1,500nM for the norepinephrine transporter (NET) (181-fold lower than for the DAT), and >10,000nM for the serotonin transporter (SERT) (>1,205-fold lower than for the DAT).[5] The inhibitory potencies (IC50Tooltip half-maximal inhibitory concentration) of mesocarb at the human monoamine transporters in vitro have been reported to be 0.49 ± 0.14μM at the DAT, 34.9 ± 14.08μM at the NET (71-fold lower than for the DAT), and 494.9 ± 17.00μM at the SERT (1,010-fold lower than for the DAT).[10]
In 2021, it was discovered that mesocarb is not a conventional DRI but acts as a DAT allosteric modulator or non-competitive inhibitor.[8][9][10] In accordance with its nature as an atypical DAT blocker, the drug has atypical effects relative to conventional DRIs.[8][9][10][5] As an example, it shows greater antiparkinsonian activity relative to other DRIs in animals.[5]
Mesocarb had erroneously been referred to as a prodrug of amphetamine.[34] However, this was based on older literature that relied on gas chromatography as an analytical method. Subsequently, with the advent of mass spectroscopy, it has been shown that presence of amphetamine in prior studies was an artifact of the gas chromatography method.[35] More recent studies using mass spectroscopy show that negligible levels of amphetamine are released from mesocarb metabolism.[33]
Feprosidnine (Sydnophen) is converted from the hydrochloride salt (1) into the freebase amine (2). This is then treated with phenylisocyanate (3).
History
Mesocarb was first described in the scientific literature by 1971.[2][13][14][11] It is said to have been used as a pharmaceutical drug from 1971 until 2008.[15] It was said to have been discontinued by its manufacturer in 2008 for business reasons unrelated to the drug itself.[15]
Society and culture
Names
Mesocarb is the generic name of the drug and its INNTooltip International Nonproprietary Name.[12] It is also known by the synonym fensidnimine as well as by the brand names Sydnocarb and Synocarb.[2][3][12][38] The drug is additionally known by its developmental code name MLR-1017 (for Parkinson's disease).[7]
Status
Mesocarb is almost unknown in the western world and is neither used in medicine nor studied scientifically to any great extent outside of Russia and other countries in the former Soviet Union. It has however been added to the list of drugs under international control and is a scheduled substance in most countries, despite its multiple therapeutic applications and reported lack of significant abuse potential.[39]
Research
Parkinson's disease
Mesocarb, has been under development for the treatment of Parkinson's disease since 2016.[6][7] As of February 2023, it is in phase 1clinical trials for this indication.[7] However, no recent development has been reported.[7] Mesocarb's active enantiomer armesocarb is also under development.[16]
