the discovery of the "splicing" of the gene transcripts, the list would include the whole molecular genetics of the lambda bacteriophage, the notions of "promotor," "repressor," and "integration," the discovery of the reverse flow of genetic information, the very existence of oncogenes, the S'-terminal "cap" struc ture of eukaryotic mRNAs, ... Electronmicroscopy, ultracentrifugation and tissue culture were the landmarks on the way of the young science. During the past few years, however, a major (and not so silent) revolution took place: recombinant DNA technology with all its might entered in our laboratories, and restriction mapping of cloned genomes and sequencing gels have replaced plaque counting and sucrose gradients. The new techniques have made it possible to "dissect" the entire genome of a virus at the molecular level, and studies that would have been dreamt of just in the mid-seventies became the everyday experiments of our days. With new insight into the structure of viral genomes, and a deeper understanding of the mechanisms that regulate their expression, our view of viruses was bound to change: this volume bears witness to this impressive advance.

Research on antiviral drugs and their mode of action in infected cells. in animals and in man. has led to a better understanding of the molecular pro cesses involved in virus replication. Screeninq of large numbers of natural and semisynthetic compounds resulted in the characterization of certain sub stances that had a limited efficiency as antiviral druqs. A few chemically synthesized compounds were also found to be effective as antiviral agents in the chemotherapy of human virus diseases. A major difficulty in the develop ment of effective antiviral agents has been the lack of selectivity. and toxicity for uninfected cells. of drugs that effectively inhibited virus replication in vitro. Further understanding of the molecular processes of virus replication in infected cells has resulted in the development of new antivirals directed at virus-coded enzymes or proteins. Recent studies on antivirals that are activated by the herpes simplex virus type l-coded thy midine kinase from a prod rug to an antiviral drug have opened new directions in the development of effective antiviral drugs. The present book deals with a number of antiviral drugs effective against herpes simplex viruses and provides some insight into the molecular aspects of virus replication. It also throws light on the new approaches to the development of antiviral drugs. The molecular basis of the antiviral activity of new and known drugs and their possible use in chemotherapy of viral disease are presented in this book.
