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)
As so far a singularity among opioid peptides, bovine beta-casomorphin-5 has been shown to display pronounced cardiatic activities. The gene sequence of a human beta-casomorphin-5, including plasmid insertion and fusion protein expression and cleavage instrumentary, has been synthesized by a manual phosphoramidite procedure and cloned in a bacterial system.
BVDU [(E)-5-(2-bromovinyl)-2'-deoxyuridine] has proved effective in the treatment of varicella-zoster virus diseases in patients with malignancies. In 13 out of 20 patients a prompt cessation of new vesicle formation accompanied by rapid resolution of fever, crusting and complete epithelialisation of cutaneous lesions were noted. Only in few cases a… (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)
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)
Four novel analogues of (E)-5-(2-bromovinyl)-2'-deoxyuridine [(E)-BrVUdR]--the (E)- and (Z)-isomer of 5-(2-fluorovinyl)-UdR (FVUdR), (Z)-5-(2-carboxy-2-fluorovinyl)-UdR [(Z)-COOH-FVUdR], and (E)-5-(2-ethoxyvinyl)-UdR [(E)-EOVUdR] were compared with the reference compounds (E)-BrVUdR and 5-vinyl-UdR (VUdR) for their inhibitory effects on plaque formation of… (More)
