  Sphingomyelin analogues as inhibitors of sphingomyelinase

  摘要：

  To search for neutral sphingomyelinase inhibitors we designed and synthesized hydrolytically stable analogues of sphingomyelin. The novel compounds 8 and 9 which were replaced the phosphodiester moiety of sphingomyelin with the carbamate moiety showed inhibitory activity with an IC50 value of muM on neutral sphingomyelinase in rat brain microsomes. Compound 8i showed a selective neutral sphingomyelinase inhibitory activity. (C) 2003 Elsevier Science Ltd. All rights reserved.

  Resistance to endocrine and chemotherapies remains the primary cause of breast cancer treatment failure. We have synthesized four novel d-erythro N-octanoyl sphingosine analogs and catalogued their activity in drug-sensitive (MCF-7), endocrine-resistant (MDA-MB-231) and chemoresistant (MCF-7TN-R) breast cancer cells.3-(4,5-Dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to determine cell viability; colony assay was performed to determine effects on clonogenic survival and H-1 NMR, C-13 NMR, HPLC spectra and elemental analytical data analyses were used to determine analog identity and purity.All four analogs inhibited both viability and clonogenic survival, with analog C exhibiting a log-fold improvement in anti-survival activity compared to the parent compound.With resistance to current breast cancer chemotherapies on the rise, the development of novel therapeutic targets is of growing importance. Our results show that lipid analogs have therapeutic potential in treating chemo- and endocrine-resistant breast cancer.
