  Synthesis and biological evaluation of nucleobase-modified analogs of the anticancer compounds 3′-C-ethynyluridine (EUrd) and 3′-C-ethynylcytidine (ECyd)

  摘要：

  A series of nucleobase-modified analogs of the anticancer compounds 3'-C-ethynyluridine (EUrd) and 3'-C-ethynylcytidine (ECyd) were designed to overcome the strict substrate specificity of the activating uridine-cytidine kinase. EUrd, ECyd and target nucleosides were obtained using a short convergent synthetic route utilizing diacetone-alpha-D -glucose as starting material. 5-lodo -substituted EUrd was the most potent inhibitor among the novel nucleobase-modified analogs in in vitro assays against human adenocarcinoma breast and prostate cancer cells with IC50 values down to 35 nM.

  A focused nucleoside library was constructed around a 3′-C-ethynyl-d-ribofuranose sugar scaffold, which was coupled to variously modified purine nucleobases. The resulting nucleosides were probed for their ability to inhibit tumor cell proliferation, as well as for their activity against a panel of relevant human viruses. While C6-aryl substituted purine nucleosides were found to be weakly active,

  A series of new nucleoside analogues based on a C-3 branched ethynyl sugar derivative as present in 3'-C-ethynylcytidine (ECyd) and -adenosine (EAdo), combined with modified purine bases was synthetized and evaluated against a broad array of viruses and tumour cell lines. The pronounced cytostatic activity of EAdo was confirmed. EAdo and its 2,6-diaminopurine analogue showed inhibitory activity against vaccinia virus (EC50: 0.31 and 51 mu M, respectively). Derivative 10 on the other hand was found active against varicella zoster virus (EC50: 4.68 mu M). (C) 2016 Elsevier Ltd. All rights reserved.

  A series of conformationally restricted and nucleobase-modified analogs of the anticancer compound 3'-C-ethynylcytidine (ECyd) and its uracil analog (EUrd) have been synthesized While none of,the conformationally restricted analogs displayed anticancer activity, 5-iodo-EUrd and 5-bromo-EUrd displayed potent anticancer activity with IC50 values of 35 nM and 0.73 mu M.
