In yeast cells, the intra-S-phase checkpoint slows down the rate of DNA replication in response to DNA damage. Here we showed that a similar checkpoint mechanism is present and activated by anti-tumour drugs in HL-60 and Epstein-Barr virus (EBV)-transformed human lymphoblastoid cells. Using

2'-deoxy-2'-(18)F-fluoro-5-fluoro-1-beta-D-arabinofuranosyluracil ((18)F-FFAU) has been synthesized and evaluated in HT-29 cells as a potential PET agent for herpes simplex virus type 1 thymidine kinase (HSV1-tk) gene

The genus Amycolatopsis is a member of the phylogenetic group nocardioform actinomycetes, which also includes the genus Mycobacterium. Members of this group have a characteristic cell envelope structure, dominated by various complex lipids and polysaccharides. Amongst these, lipoglycans are of

A series of 4'-thio-D-arabinofuranosylpurine nucleosides was prepared and evaluated as potential anticancer agents. The details of a convenient and high-yielding synthesis of the carbohydrate precursor 1-O-acetyl-2,3,5-tri-O-benzyl-4-thio-D-arabinofuranose (6) are presented. Proof of structure and
