  Synthesis of non-competitive inhibitors of Sphingomyelinases with significant activity

  摘要：

  A series of short-chain analogues of N-palmitoylsphingosine-1-phosphate, modified by replacement of the phosphate and the long alkenyl side chain with hydrolytically stable difluoromethylene phosphonate and phenyl, respectively, were prepared to study the structure-activity relationship for inhibition of sphingomyelinase. The study revealed that inhibition is highly dependent upon the stereochemistry of the asymmetric centers of the acylamino, moiety, and resulted in identification of a non-competitive inhibitor with the same level of inhibitory activity of schyphostatin, the most potent of the few known small molecular inhibitors of sphingomyelinase.

  A sphingomyelin analogue 2, in which the long alkenyl chain and the phosphodiester moiety of sphingomyelin were replaced by a phenyl and an isosteric difluoromethylenephosphonic acid, was prepared to evaluate its inhibitory potency to sphingomyelinase. The analogue non-competitively inhibited the neutral sphingomyelinase in bovine brain microsomes with an IC50 Of 400 muM. The compound had the ability to suppress tumor necrosis factor alpha -induced apoptosis of PC-12 neurons at a low concentration of 0.1 muM. (C) 2001 Elsevier Science Ltd. All rights reserved.
