(±)-BI-D is a potent ALLINI(An allosteric IN inhibitor) that binds integrase at the LEDGF/p75 binding site.IC50 value: 2.4-2.9 μM(HIV-Luc infection of WT and Hdgfrp2 KO cells) [1]Target: integrase inhibitorin vitro: Approximately 2.4-2.9 μM of BI-D was required to inhibit 50% of HIV-Luc infection of WT and Hdgfrp2 KO cells, while the IC50 decreased dramatically, to 160-200 nM, in Psip1 and double-KO cells [1].
