The present invention provides antibody compounds that contain a substitution of arginine for the reactive lysine residue (Lys99) in the hydrophobic cleft (38C2_Arg). The invention also provides antibody drug conjugate compounds (ADCs) that contain cargo moieties that are site-specifically conjugated to the engineered arginine residue in the 38C2_Arg variant antibody. Further provided in the invention are therapeutic applications of the compounds.

Three groups of bile acid derivatives with acetylenic moieties, such as propargyl, hex-5-ynoyl, and 4,7,10,13-tetraoxahexadec-15-ynoyl ones, were obtained. The cytotoxic activity of the synthesized compounds against hepatocellular carcinoma (HepG2, Huh7), prostate cancer (PC3), and human embryonic kidney (HEK293) cell lines was studied. The parameters enabling estimation of the total lipophilicity

Homogeneous antibody-drug conjugates (ADCs) that use a highly reactive buried lysine (Lys) residue embedded in a dual variable domain (DVD)-IgG1 format can be assembled with high precision and efficiency under mild conditions. Here we show that replacing the Lys with an arginine (Arg) residue affords an orthogonal ADC assembly that is site-selective and stable. X-ray crystallography confirmed the location of the reactive Arg residue at the bottom of a deep pocket. As the Lys-to-Arg mutation is confined to a single residue in the heavy chain of the DVD-IgG1, heterodimeric assemblies that combine a buried Lys in one arm, a buried Arg in the other arm, and identical light chains, are readily assembled. Furthermore, the orthogonal conjugation chemistry enables the loading of heterodimeric DVD-IgG1s with two different cargos in a one-pot reaction and thus affords a convenient platform for dual-warhead ADCs and other multifaceted antibody conjugates.
