  The synthesis of 5-heteroaryl-substituted 2'-deoxyuridines is described. The heteroaromatics were obtained from three different 5-substituted 2'-deoxyuridines. Cycloaddition reaction of nitrile oxides on the 5-ethynyl derivative 1 gave the isoxazoles 4a-e. The thiazole derivatives 14a-c were obtained from the 5-thiocarboxamide 11, while 5-pyrrol-1-yl-2'-deoxyuridine (17) could be synthesized directly

  properties of all furan containing nucleosides, identifies the furan thymidine analogue, 5-(fur-2-yl)-2'-deoxyuridine, as the best candidate for use as a responsive fluorescent probe in nucleic acids. 5-(fur-2-yl)-2'-deoxyuridine was then converted to the corresponding phosphoramidite and site specifically incorporated into DNA oligonucleotides with greater than 88% coupling efficiency. Such furan-modified

  2'-Deoxyuridines with a five-membered heterocyclic substituent in the 5-position were synthesized by palladium-catalyzed coupling reactions of 5-iodo-2'-deoxyuridine with the activated heteroaromatics. Further modification of the compound with the 5-thien-2-yl substituent gave 5-(5-bromothien-2-yl)-2'-deoxyuridine and 5-(5-chlorothienyl-2-yl)-2'-deoxyuridine. Both compounds show potent and selective activity against herpes simplex virus type 1 and varicella-zoster virus.
• 5-Heteroaryl-2'-deoxyuridine Analogs. Synthesis and Incorporation into High-Affinity Oligonucleotides

  日期：1994.6

  A series of C-5 heteroaryl-2'-deoxyuridines were synthesized from 5-iodo-2'-deoxyuridine. Palladium catalyzed coupling with heteroarylstannanes proved to be a convenient and general method of preparation. Oligonucleotides containing pyridine-, thiophene-, thiazole-, and imidazole-substituted 2'-deoxyuridine analogs gave enhanced thermal stability to complementary RNA relative to thymidine. Thermal denaturation studies showed that oligodeoxynucleotides (ODNs) containing 5-(thiazol-2-yl)-2'-deoxyuridine exhibit the highest thermal denaturation (Tm) and therefore may increase the potency of these ODNs to inhibit gene expression in a sequence specific manner.
• Synthesis and in vitro antileishmanial activity of 5-substituted-2′-deoxyuridine derivatives

  We report herein the synthesis and the in vitro antileishmanial evaluation of 5-substituted-2'-deoxyuridine nucleosides. The most active compound against Leishmania donovani promastigotes was Thia-dU (3a) with an IC50 = 3 mu M. This compound exhibited the same activity as zidovudine (3'-azido-2'-deoxythymidine) used as nucleoside reference compound. Considering the cytotoxicity of synthetic compounds on peritoneal murine macrophages., the most toxic compound was MeThio-dU (3d) with a MTC at 10 mu M. Only Methia-dU (3b) was active against intramacrophagic amastigotes with an IC50 = 6.5 mu M. This latter can now be evaluated in vivo, for further investigations through structure-based drug design.
