- Abstract
The 2',3'-dideoxyriboside (ddDAPR), 2',3'-didehydro-2',3'-dideoxyriboside (ddeDAPR) and 3'-azido-2',3'-dideoxyriboside (AzddDAPR) of 2,6-diaminopurine have been previously recognized as potent inhibitors of human immunodeficiency virus replication. These compounds are also potent inhibitors of adenosine deaminase and inhibit the deamination of 9-beta-D-arabinofuranosyladenine (araA). ddDAPR, ddeDAPR and AzddDAPR markedly potentiate the antiviral activity of araA against herpes simplex virus type 1 (HSV-1), type 2 (HSV-2) and vaccinia virus (VV). When used at a concentration of 20 micrograms/ml, which had by itself no antiviral effect, ddDAPR, ddeDAPR and AzddDAPR increased the ability of araA to suppress HSV-1, HSV-2 and VV yield by several orders of magnitude. The maximum antiviral effect was obtained with the combinations of ddDAPR or ddeDAPR with araA concentrations of 1 and 10 micrograms/ml.
