  Synthesis, resolution and absolute configuration of a tolperisone metabolite

  摘要：

  1-(4'-Hydroxymethyl-phenyl)-2-methyl-3-(piperidine-1-yl)-propane-1-one M2, a metabolite of tolperisone, was synthesised in a solvent-free Mannich reaction. The optical resolution was carried out by diastereoisomeric salt formation and separation, for which three resolving agents ((2R,3R)-O,O'-dibenzoyl tartaric acid, (2R,3R)-O,O'-di-p-toluoyl tartaric acid and (R)-2-hydroxy-4-(2-methoxyphenyl)-5.5-dimethyl-1,3,2-dioxaphosphorinane-2-oxide (anicyphos)) were found. The absolute configuration of M2 was determined by the single-crystal X-ray diffraction method. (C) 2001 Elsevier Science Ltd. All rights reserved.

  Phase I metabolites of mephedrone display biological activity as substrates at monoamine transporters

  摘要：

  Background and Purpose4‐Methyl‐N‐methylcathinone (mephedrone) is a synthetic stimulant that acts as a substrate‐type releaser at transporters for dopamine (DAT), noradrenaline (NET) and 5‐HT (SERT). Upon systemic administration, mephedrone is metabolized to several phase I compounds: the N‐demethylated metabolite, 4‐methylcathinone (nor‐mephedrone); the ring‐hydroxylated metabolite, 4‐hydroxytolylmephedrone (4‐OH‐mephedrone); and the reduced keto‐metabolite, dihydromephedrone.Experimental ApproachWe used in vitro assays to compare the effects of mephedrone and synthetically prepared metabolites on transporter‐mediated uptake and release in HEK293 cells expressing human monoamine transporters and in rat brain synaptosomes. In vivo microdialysis was employed to examine the effects of i.v. metabolite injection (1 and 3 mg·kg−1) on extracellular dopamine and 5‐HT levels in rat nucleus accumbens.Key ResultsIn cells expressing transporters, mephedrone and its metabolites inhibited uptake, although dihydromephedrone was weak overall. In cells and synaptosomes, nor‐mephedrone and 4‐OH‐mephedrone served as transportable substrates, inducing release via monoamine transporters. When administered to rats, mephedrone and nor‐mephedrone produced elevations in extracellular dopamine and 5‐HT, whereas 4‐OH‐mephedrone did not. Mephedrone and nor‐mephedrone, but not 4‐OH‐mephedrone, induced locomotor activity.Conclusions and ImplicationsOur results demonstrate that phase I metabolites of mephedrone are transporter substrates (i.e. releasers) at DAT, NET and SERT, but dihydromephedrone is weak in this regard. When administered in vivo, nor‐mephedrone increases extracellular dopamine and 5‐HT in the brain whereas 4‐OH‐mephedrone does not, suggesting the latter metabolite does not penetrate the blood–brain barrier. Future studies should examine the pharmacokinetics of nor‐mephedrone to determine its possible contribution to the in vivo effects produced by mephedrone.

  scope compared with previously reported methods that employ carboxylic acids as substrates. A working hypothesis of pull-and-push-driven fluorinative C–C bond cleavage was successfully demonstrated by the simple addition of diethylaminosulfur trifluoride (DAST) derivatives to α-oximinoketones. The designed reaction system led to a highly efficient and chemoselective reaction. The wide availability of the

  通过将活化的酮识别为起始原料，开发了一种制备酰基氟的新方法。与先前报道的使用羧酸作为底物的方法相比，该方法提供了不同的范围。通过简单地将二乙基氨基三氟化硫（DAST）衍生物添加到α-肟基酮中，成功地证明了推拉驱动式C-C键断裂的有效假设。设计的反应系统可导致高效且化学选择性的反应。酮的广泛可用性允许使用一系列合成有用的芳酰基和脂族酰基氟，包括那些含有手性骨架的氟。该方法是温和的，快速的，可扩展的，并且可能一站式操作。
