COMPOSITIONS AND METHODS FOR THE TREATMENT OF HUMAN IMMUNODEFICIENCY VIRUS

, (2020/12/30)
Compositions and methods for the treatment of viral infections include conjugates containing inhibitors of viral gp120 receptor (e.g., temsavir, BMS-818251, DMJ-ll-121, BNM-IV-147, or analogs thereof) linked to an Fc monomer, an Fc domain, and Fc-binding peptide, an albumin protein, or albumin- binding peptide. In particular, conjugates can be used in the treatment of viral infections (e.g., HIV infections).

The design, synthesis, thermodynamic and crystallographic characterization of a potent, broad spectrum, second-generation HIV-1 entry inhibitor that engages conserved carbonyl hydrogen bonds within gp120 has been achieved. The optimized antagonist exhibits a submicromolar binding affinity (110 nM) and inhibits viral entry of clade B and C viruses (IC50 geometric mean titer of 1.7 and 14.0 μM, respectively), without promoting CD4-independent viral entry. The thermodynamic signatures indicate a binding preference for the (R,R)- over the (S,S)-enantiomer. The crystal structure of the small-molecule/gp120 complex reveals the displacement of crystallographic water and the formation of a hydrogen bond with a backbone carbonyl of the bridging sheet. Thus, structure-based design and synthesis targeting the highly conserved and structurally characterized CD4-gp120 interface is an effective tactic to enhance the neutralization potency of small-molecule HIV-1 entry inhibitors.
