  Structural Modification of the Designer Stimulant α-Pyrrolidinovalerophenone (α-PVP) Influences Potency at Dopamine Transporters

  摘要：

  alpha-Pyrrolidinovalerophenone (alpha-PVP, 7) is an illegal synthetic stimulant that is being sold on the clandestine market as "flakka" and "gravel". The potent pharmacological effects of alpha-PVP are presumably mediated by inhibition of dopamine uptake at the dopamine transporter (DAT). However, little is known about how structural modification of alpha-PVP influences activity at DAT. Eleven analogs of alpha-PVP were synthesized and examined for their ability to inhibit uptake of [H-3]clopamine and [H-3]serotonin in rat brain synaptosomes. None of the analogs significantly inhibited [H-3]serotonin uptake when tested at 10 mu M at the serotonin transporter (SERT). All of the analogs behaved as DAT reuptake inhibitors, but potencies varied over a >1500-fold range. Potency was primarily associated with the nature of the alpha-substituent, with the more bulky substituents imparting the highest potency. Expansion of the pyrrolidine ring to a piperidine reduced potency up to 10-fold, whereas conformational constraint in the form of an aminotetralone resulted in the least potent compound. Our study provides the first systematic and comparative structure activity investigation on the ability of alpha-PVP analogs to act as inhibitors of DAT.

  A metal‐ and catalyst‐free thiyl‐radical‐mediated activation of alkanes is described. Tetrafluoropyridinyl disulfide is used to perform thiolation of the C−H bonds under irradiation with 400 nm light‐emitting diodes. The key C−H activation step is believed to proceed via hydrogen‐atom abstraction effected by the fluorinated thiyl radical. Secondary, tertiary, and heteroatom‐substituted C−H bonds can

  The 4-hydroxy-5,6-dihydropyrone template was utilized as a flexible scaffolding from which to build potent active site inhibitors of HIV protease. Dihydropyrone 1c (5,6-dihydro-4-hydroxy-6-phenyl-3-[(2-phenylethyl)thio]-2H-pyran-2-one) was modeled in the active site of HIV protease utilizing a similar binding mode found for the previously reported 4-hydroxybenzopyran-2-ones. Our model led us to pursue
