The work described here is an attempt to synthesis nucleoside analogues which are targetted against the replicase of negative-strand viruses. Two lines of investigation have been attempted: (i) the synthesis of 5-vinyl substituted pyrimidine ribonucleosides and (ii) the synthesis of potential nucleotide pro-drugs. A series of compounds of type (i) have been synthesised and submitted for biological evaluation. Strategies for the synthesis of compounds of type (ii) have been developed but we have not had time to prepare sufficient suitable material for testing purposes. (js).

Largely in response to the AIDS epidemic, the amount of research directed toward the discovery of antiviral agents has greatly expanded. This new volume focuses on the potential of nucleotides to exert potent in vivo antiviral effects. It presents the findings of an international group of scientists who are carrying out research at the forefront of the nucleotide drug design. Twelve chapters describe many new concepts and results, much of which has been previously unpublished. This book assembles a valuable collection of information, offering insight into this increasingly important research topic.

Acyclovir (ACV) is an acyclic guanine nucleoside analogue used in the treatment of herpes simplex virus (HSV) and varicella zoster virus (VZV) infections. The human herpes virus-encoded thymidine kinase (HHV-TK) phosphorylates ACV generating ACV monophosphate, which is then converted to the active form ACV triphosphate by cellular kinases. The ProTide approach, causing the direct release of the monophosphate form into the cell, allows bypass of the first phosphorylation step of nucleoside analogues. In previous studies acyclovir ProTides were found to be active in vitro against human immunodeficiency virus (HIV), demonstrating a successful release of ACV monophosphate into the cell. In this work, an extensive study of structure-activity relationship was carried out varying the masking groups of the ACV ProTide. Subsequently, several substituents were considered on specific position of the guanine base and side chain of ACV resulting in the synthesis of the aryl phosphoramidate derivatives of ganciclovir, penciclovir, 6-O-alkyl acyclovir, 8-bromoacyclovir, and 8- methylacyclovir. These derivatives were evaluated in vitro for their antiviral activity against HSV, VZV, human cytomegalovirus (HCMV), and HIV. Enzymatic and molecular modeling studies were carried out in order to investigate the bioactivaton of the phosphoramidate derivatives synthesised in this work and correlate these results with their biological activity. Finally, the ProTide approach was also applied to cidofovir resulting in the formation of the phosphonoamidate derivative of cyclic cidofovir. The in vitro antiviral activity of this compound against herpes viruses and poxviruses is reported, as well as investigation of the mechanism of activation, using enzymatic and molecular modeling studies.
