The discovery and optimization of Δ-5 desaturase (D5D) inhibitors are described. Investigation of the 1,3-oxazolidin-2-one scaffold was inspired by a pharmacophore model constructed from the common features of several hit compounds, resulting in the identification of 3,5-diphenyl-1,3-oxazolidin-2-one 5h as a novel lead showing potent in vitro activity. Subsequent optimization focused on the modification of two metabolic sites, which provided (4S,5S)-5i, a derivative with improved metabolic stability. Moreover, adding a substituent into the upper phenyl moiety further enhanced the intrinsic activity, which led to the discovery of 5-[(4S,5S)-5-(4fluorophenyl)-4-methyl-2-oxo-1,3-oxazolidin-3-yl]benzene-1,3-dicarbonitrile (4S,5S)-5n, endowed with excellent D5D binding affinity, cellular activity, and high oral bioavailability in a mouse. It exhibited robust in vivo hepatic arachidonic acid/dihomo-γ-linolenic acid ratio reduction (a target engagement marker) in an atherosclerosis mouse model. Finally, an asymmetric synthetic procedure for this compound was established.

Enantiomerically pure 1, 2-diamino-1-(4-fluorophenyl)propanes were synthesized by stereospecific and stereoselective procedures by use of the (1R, 2S)- and (1S, 2R)-2-amino-1-(4-fluorophenyl)propanols (12a) as intermediates. The enantiomeric purity was determined by (1)H NMR spectroscopy after conversion of the propanolamines and the diamines with (1R)-myrtenal into mono- and diimines. For the coordination to platinum the diamines were reacted with K(2)PtCl(4). The resulting dichloroplatinum(II) complexes 4F-Ph/Me-PtCl(2) were tested for antiproliferative activity on the MCF-7 breast cancer cell line. (SS)- and (RR)-4F-Ph/Me-PtCl(2) produced the strongest inhibitory effect. Both complexes showed cytocidal effects, (SS)-4F-Ph/Me-PtCl(2) even in a concentration of 1 microM. The (1S, 2R)- and (1R, 2S)-configurated complexes were far less active (SS > RR > RS = SR) and comparable in this respect with the standard cisplatin.
