lüll Water-insoluble camptothecin analogues as potential antiviral drugs Pantazis P; Han Z; Chatterjee D; Wyche JJ Biomed Sci 1999[Jan]; 6 (1): 1-7In addition to being causative agents of infectious diseases in animals and humans, DNA viruses have served as models for the study of eukaryotic molecular mechanisms including replication and transcription. Studies of DNA virus functions utilizing cell-free systems and virus-infected cells in culture, in the presence of the anticancer drug camptothecin (CPT), have demonstrated that CPT is a potent inhibitor of replication, transcription and packaging of double-stranded DNA-containing adenoviruses, papovaviruses and herpesviruses, and the single- stranded DNA-containing autonomous parvoviruses. CPT inhibits viral functions by inhibiting topoisomer- ase I, a host cell enzyme required for initiation and completion of the viral functions. These findings indicate that CPT analogues could be developed for use as potent drugs against DNA viruses.|Adenoviridae/drug effects/genetics/metabolism[MESH]|Animals[MESH]|Antiviral Agents/*pharmacology[MESH]|Camptothecin/*analogs & derivatives/*pharmacology[MESH]|DNA Viruses/*drug effects/genetics/metabolism[MESH]|Enzyme Inhibitors/*pharmacology[MESH]|Herpesviridae/drug effects/genetics/metabolism[MESH]|Humans[MESH]|Papillomaviridae/drug effects/genetics/metabolism[MESH]|Parvovirus/drug effects/genetics/metabolism[MESH]|Polyomaviridae[MESH]|Solubility[MESH] |
