5-Formyl-2'-deoxyuridine (fdUrd) was prepared by a new method starting from thymidine and investigated for its influence both on proliferation of cultured mammalian cells and virus replication in vitro. The compound was found to have strong cytostatic and antiviral properties: 50% inhibition of proliferation of BHK 21/C13 cells or Ehrlich ascites tumour(More)
A number of novel 5-substituted 2'deoxypyrimidine nucleosides exhibited antiviral activity against herpes simplex virus type 1 strain V3 (HSV-1-V3) when assayed under one-step conditions in primary human lung fibroblast j(PHLF) cell cultures, and compared with the reference compounds cytosine arabinoside (ara-C), 5-iodo-2'-deoxyuridine (IUdR), and(More)
The 3'-fluoromodified nucleotide analogs 3'-fluorothymidine triphosphate (FdTTP), 2',3'-dideoxy-3'-fluoro-5-chlorouridine triphosphate (F-5CldUTP), 2',3'-dideoxy-3'-fluoro-5-ethyluridine triphosphate (F-5EtdUTP), 2',3'-dideoxy-3'-fluorouridine triphosphate (FdUTP), and 2',3'-dideoxy-3'-fluoro-5-fluorouridine triphosphate (F-5FdUTP) as well as(More)
(E)-5-(2-Bromovinyl)-2'-deoxyuridine (1; BrVUdR) inhibits the replication of herpes simplex virus type 1 (HSV-1) and of varicella-zoster virus (VZV) in vitro at concentrations of 0.01 to 0.23 mumol/l, whereas herpes simplex virus type 2 (HSV-2) is influenced only at 5.5 to 27 mumol/l. In comparison to some classical and newly developed antiherpetics, i. e.(More)
In a series of 5-vinyl-2'-deoxyuridine (VUdR) analogues (5-(2-X-vinyl)-UdRs) the (E)-5-(2-bromovinyl)-UdR (E-BrVUdR) proved the most potent inhibitor of plaque formation of two herpes simplex virus type 1 (HSV-1) strains in human embryonic lung fibroblast (HELF) and African green monkey kidney (Vero) cell cultures.
