  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).

  Design, synthesis, and evaluation of β-galactosylceramide mimics promoting β-glucocerebrosidase activity in keratinocytes

  摘要：

  We have established an efficient synthesis of mimics of beta-galactosylceramide (beta-GalCer) increasing a beta-glucocerebrosidase (beta-GlcCer'ase) activity that associates with the skin barrier function. Among the synthetic beta-GalCer analogues (6a-6e) described herein, compound 6e exhibited a potent effect on the activation of beta-GlcCer'ase function in vitro and reduced the transepidermal water loss (TEWL) level in a UVB-induced barrier disrupted mice model. These findings indicated that compound 6e could be useful for cosmetics and medicines to improve skin barrier function. (C) 2003 Elsevier Science Ltd. All rights reserved.

  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.
