Chemically Programmed Antibodies AS HIV-1 Attachment Inhibitors.

ABSTRACT: Herein we describe the design and application of two small-molecule anti-HIV compounds for the creation of chemically programmed antibodies. N-acyl-β-lactam derivatives of two previously described molecules BMS-378806 and BMS-488043 that inhibit the interaction between HIV-1 gp120 and T-cells were synthesized and used to program the binding activity of aldolase antibody 38C2. Discovery of a successful linkage site to BMS-488043 allowed for the synthesis of chemically programmed antibodies with affinity for HIV-1 gp120 and potent HIV-1 neutralization activity. Derivation of a successful conjugation strategy for this family of HIV-1 entry inhibitors enables its application in chemically programmed antibodies and vaccines and may facilitate the development of novel bispecific antibodies and t
