[Inhibitors of ADP ribosylation as antiviral agents: an experimental study in a model of HIV infection].
The paper deals with further search for substances modifying metabolic processes, changing the conditions of virus existence in the host cell and, consequently, possessing a certain antiviral activity. The antiviral effects of aromatic carbonic acids amides including trisubstituted benzamides and nicotinamide were tested. Five out of 8 substances tested possessed antiviral activity which might be due to their capacity to inhibit the activity of the enzymes of ADP-ribosylation. By blocking cellular processes of ADP-ribosylation, the substances under study depressed DNA capacity for reparation, inhibited differentiation and transformation of cells, i.e. had an indirect effect on reproduction of viruses. The universal nature of the processes coursing with participation of NAD(+)-dependent ADP-ribosylation suggests that the range of antiviral activity of inhibitors of mono- and poly-ADP-ribosylation would not be limited to HIV infection but would be rather wide.
