Human TCB dose-response curves for: AZT alone (solid diamond, 0 -29.3 ηM); and the same doses of AZT with 18.7 μM WR1065 added to each dose (solid square). Note that WR1065 alone inhibited HIV-1 replication, and when WR1065 was added to 2.2 ηM AZT, the % inhibition of HIV-1 replication increased by 50%; high doses of AZT that completely inhibit virus replication were not informative.
