  Studies on scavenger receptor inhibitors. Part 1: synthesis and structure–activity relationships of novel derivatives of sulfatides

  摘要：

  Scavenger receptors have been proven to be implicated in the formation of atherosclerotic lesions. A series of novel derivatives of sulfatides were synthesized, and their inhibitory activities against incorporation of Dil-acetyl-LDL into macrophages were evaluated in order to clarify the structure-activity relationships of sulfatides as a scavenger receptor inhibitor and find out novel inhibitors with synthetic easiness. The chemical modification of the substructures of sulfatides led to the establishment of the following structure-activity relationships (1) the ceramide moiety can be replaced with another structure bearing two long chains, (2) the galactose moiety can be replaced with another structure or be deleted without a large decrease in the inhibitory activity, (3) the sulfate moiety was crucial, and it was the most preferable functional group for a potent inhibitory activity. The inhibitory activity of (S)-2-octadecanoylamino-2-tetradecylcarbamoyl)ethyl sulfate sodium salt (3a) against incorporation of Dil-acetyl-LDL into macrophages was proven to be based on the inhibition against the binding of acetyl-LDL to the surface of macrophages. We discovered novel scavenger receptor inhibitors with synthetic easiness, such as (S)-2-octadecanoylamino-2-(tetradccylcarbamoyl)ethyl sulfate sodium salt (3a) and 2-octadecanoylamino-1-(octadecanoylaminomethyl)ethyl sulfate sodium salt (13q).

  Various sulfated cerebroside analogs, which are mimicks of cerebroside, have been prepared from per-O-acetylated D-glucose, per-O-acetylated D-galactose, and per-O-acetylated D-lactose with ethyleneglycol dodecyl ether, 3-docosyloxy-1-propanol, 2-hydroxymethyl-1, 3-O-dimyristyl-1, 3-propanediol, and L-serine diamide derivatives as ceramide moieties. The synthesized sulfated glycolipids showed anti-HIV-1 activities.
