2-[(Diphenylmethyl)sulfinyl]acetamide (modafinil, (±)-1) is a unique dopamine uptake inhibitor that binds the dopamine transporter (DAT) differently than cocaine and may have potential for the treatment of psychostimulant abuse. To further investigate structural requirements for this divergent binding mode, novel thio- and sulfinylacetamide and ethanamine analogues of (±)-1 were synthesized wherein (1) the diphenyl rings were substituted with methyl, trifluoromethyl, and halogen substituents and (2) substituents were added to the terminal amide/amine nitrogen. Halogen substitution of the diphenyl rings of (±)-1 gave several amide analogues with improved binding affinity for DAT and robust selectivity over the serotonin transporter (SERT), whereas affinity improved at SERT over DAT for the p-halo-substituted amine analogues. Molecular docking studies, using a subset of analogues with DAT and SERT homology models, and functional data obtained with DAT (A480T) and SERT (T497A) mutants defined a role for TM10 in the substrate/inhibitor S1 binding sites of DAT and SERT.

Electron transfer in the peroxytrifluoroacetic acid-assisted sulfoxidation and oxidative destruction of benzhydryl sulfides
Akopova,Morkovnik,Khrustalev,Bicherov
, p. 1164 - 1175 (2014/03/21)
The reactions of benzhydryl sulfides Ph2CHSCH2R (R = H, CONH2, COOH, CN) with peroxytrifluoroacetic acid in CF 3COOH were studied experimentally and by the quantum chemical density functional theory (DFT) method and exhibited an unusual dependence on the substituent R. When R≠H, a complicated oxidative destruction of the substrates occurs to form 2,4,6-tribenzhydrylphenol as one of the products, while in the case of R = H, the starting benzhydryl sulfide is smoothly sulfoxidated. This fact is due to the common electron transfer from the substrate to reagent at the initial step and the difference in subsequent transformations of the species formed.

Simple synthesis of modafinil derivatives and their biological activity are described. The key synthetic strategies involve substitution and coupling reactions. We determined the anti-inflammatory effects of modafinil derivatives in cultured BV2 cells by measuring the inhibition of nitrite production and expression of iNOS and COX-2 after LPS stimulation. It was found that for sulfide analogues introduction of aliphatic groups on the amide part (compounds 11a-d) resulted in lower anti-inflammatory activity compared with cyclic or aromatic moieties (compounds 11e-k). However, for the sulfoxide analogues, introduction of aliphatic moieties (compounds 12a-d) showed higher anti-inflammatory activity than cyclic or aromatic fragments (compounds 12e-k) in BV-2 microglia cells.

supporting information; experimental part, p. 48 - 52 (2011/04/22)
A series of modafinil (1) analogues were synthesized wherein (1) para-halo-substitutents were added to the aryl rings, (2) the sulfoxide function was removed, and (3) the primary amide group was replaced with secondary and tertiary amides and amines to investigate the effects of these chemical modifications on dopamine transporter, serotonin transporter, and norepinephrine transporter binding. In addition, the locomotor-stimulant effects in mice of (±)-modafinil (1), its R-and S-enantiomers, and its para-chloro sulfinylacetamide analogue (5c) were compared to those of cocaine.
