– HIV-1 inhibitor-47 is a compound that effectively inhibits HIV-1 by preventing the vif-dependent degradation of human APOBEC3G. It has a notable inhibition effect, with an IC50 value of 14.33 μM. Additionally, HIV-1 inhibitor-47 is involved in the synthesis of derivatives of 1-(2-pyrimidinyl)piperazine, which have the potential to exhibit antianxiety, antidepressant, and antipsychotic effects [1] [2] [3].
