IQP-0528 is an antiretroviral pyrimidinedione derivative with activity against human immunodeficiency virus (HIV) in the nanomolar range. It is a non-nucleoside reverse transcriptase inhibitor that also inhibits HIV entry through an unknown mechanism thought to target a conformational epitope formed prior to the fusion of the viral envelope with the host cellular membrane. IQP-0528 is under clinical development for HIV prevention.

IQP-0528 (SJ-3366) exhibited a Ki value of 3.2 nM, with a mixed mechanism of inhibition against human immunodeficiency virus type 1 (HIV-1) reverse transcriptase, but it did not inhibit HIV-2 reverse transcriptase. SJ-3366 also inhibited the entry of both HIV-1 and HIV-2 into target cells.
