CHIMERIC TAR ENZYME CONSTRUCTION FOR HIV THERAPY

摘要

The present invention relates to molecular chimaeras, infective virions, to methods of their construction, to pharmaceutical formulations containing them, to their use in therapy, particularly virus-directed enzyme prodrug therapy particularly in the treatment of HIV, and to the use of agents which can be catalysed by a heterologous enzyme to cytotoxic or cytostatic metabolites, such as purine arabinosides and substituted pyrimidines in virus-directed enzyme prodrug therapy, in a mammalian host (e.g. human).
