DOV 216,303 is an antidepressant drug originally developed by DOV Pharmaceutical and now licensed to the larger pharmaceutical company Merck & Co., which is currently in clinical trials.[1] It is a so-called triple reuptake inhibitor (TRI), or serotonin-norepinephrine-dopamine reuptake inhibitor (SNDRI).[1][2] It is the racemic mixture of amitifadine (DOV 21,947) and its (–)-enantiomer. Its IC50 values for SERT, NET, and DAT are Ki 14 nM, 20 nM, and 78 nM, respectively.[2] It is closely related to DOV 102,677 and amitifadine, both of which are also being developed in collaboration with Merck.

  • Doses of up to 100mg per day are well tolerated with only nausea, and GI disturbances reported as side effects.
  • This compound does not cause notable shifts in LMA, and is not psychostimulant.

The effects are not long-lasting.

More recently (see attachment), it appears that the DOV compound may also be useful at increasing weight loss.

  • DOV causes a decrease in circulating triglycerides.
  • The reason for weightloss is not going to be thermogenic or psychostimulant, or chronic decrease appetite. Read article for details.

  1. 3,4-Dichlorophenylacetonitrile reacted with sodium bromate → α-bromo-3,4-dichlorophenylacetic acid methyl ester 2.
  2. Crude α-bromo-3,4-dichlorophenylacetic acid methyl ester then reacted with methylacrylate to afford the diester 3, which is converted to 1-(3,4-dichlorophenyl)-1,2-cyclopropanedicarboxylic acid dipotassium salt 4.
  3. The dipotassium salt reacts with urea to provide 1-(3,4-dichlorophenyl)-3-azabicyclo[3.1.0]hexane-2,4-dione 5, which is reduced by BH3-THF complex to afford DOV 216303.
  4. Resolution of 216303 by L-(–)-dibenzoyl tartaric acid gives the (+)-enantiomer DOV 21947.
  5. Resolution of 216303 by D-(+)-dibenzoyl tartaric acid gives the (–)-enantiomer DOV 102677.
