NBD-11021
NBD-11021 is a HIV-1 entry antagonist and CD4 antagonist. NBD-11021 binds to the Phe43 cavity of HIV-1 gp120 and competitively blocks the gp120-CD4 interaction. NBD-11021 exhibits broad-spectrum inhibitory activity against 56 HIV-1 Env pseudoviruses of different subtypes, with an IC50 of 0.6-5.3 μM. NBD-11021 inhibits CCR5- and CXCR4-tropic HIV-1, primary HIV-1, drug-resistant HIV-1, HIV-1 Env-mediated cell fusion and intercellular viral transmission. NBD-11021 can be used in studies related to HIV-1 gp120, viral entry and HIV infection.

NBD-11021 (compound 89) inhibits CCR5-tropic HIV-1ADA and CXCR4-tropic HIV-1HXB2 infection in U87-CD4-CCR5 and U87-CD4-CXCR4 cells, respectively, with IC50 values of 1.7 μM and 2.4 μM[3].
NBD-11021 exhibits broad-spectrum inhibitory activity against 56 HIV-1 Env pseudoviruses covering multiple clades, with an IC50 range of 0.6-5.3 μM and a mean IC50 of 2.38 μM[3].
NBD-11021 inhibits cell-to-cell transmission of CXCR4-tropic and CCR5-tropic HIV-1 in a co-culture system of GHOST X4/R5 target cells and chronically infected effector cells[3].
NBD-11021 inhibits single-cycle infection of HIV-1HXB2 in TZM-bl cells and multi-cycle infection of HIV-1IIIB in MT-2 cells, with IC50 values of 2.2 μM and 0.85 μM, respectively[1].
NBD-11021 (pretreated for 1 h followed by 24 h of co-culture) inhibits HIV-1 Env-mediated cell fusion between MAGI-CCR5 and HL2/3 cells, with an IC50 of 6.1 μM[1].
NBD-11021 inhibits laboratory-adapted, primary, and drug-resistant HIV-1 strains, including AZT-resistant strains, protease inhibitor-resistant strains, and gp41 fusion inhibitor-resistant strains, in MT-2 cells or PBMC[3].
NBD-11021 (pretreated for 1 h; co-cultured for 24 h) inhibits HIV-1 Env-mediated cell fusion between MAGI-CCR5 and HL2/3 cells, with an IC50 of 9.8 μM[3].
