In some aspects, the invention relates to an antibody-drug conjugate, comprising an anti-CD 19 antibody; a linker; and an active agent. The antibody-drug conjugate may comprise a self-immolative group. The linker may comprise an O-substituted oxime, e.g., wherein the oxygen atom of the oxime is substituted with a group that covalently links the oxime to the active agent; and the carbon atom of the oxime is substituted with a group that covalently links the oxime to the antibody.

In some aspects, the invention relates to an antibody-drug conjugate, comprising an anti-epidermal growth factor receptor ("EGFR") antibody; a linker; and an active agent. The antibody-drug conjugate may comprise a self-immolative group. The linker may comprise an O-substituted oxime, e.g., wherein the oxygen atom of the oxime is substituted with a group that covalently links the oxime to the drug; and the carbon atom of the oxime is substituted with a group that covalently links the oxime to the antibody.
Provided are compounds comprising a self-immolative group, and the compounds comprising a self-immolative group according to the present invention may include a protein (for example, an oligopeptide, a polypeptide, an antibody, or the like) having substrate-specificity for a target and an active agent (for example, a drug, a toxin, a ligand, a detection probe, or the like) having a specific function or activity.

In some aspects, the invention relates to an antibody-drug conjugate, comprising an antibody; a linker; and at least two active agents. In preferred embodiments, the linker comprises a peptide sequence of a plurality of amino acids, and at least two of the active agents are covalently coupled to side chains of the amino acids. The antibody-drug conjugate may comprise a self-immolative group, preferably two-self-immolative groups. The linker may comprise an O-substituted oxime, e.g., wherein the oxygen atom of the oxime is substituted with a group that covalently links the oxime to the active agent; and the carbon atom of the oxime is substituted with a group that covalently links the oxime to the antibody.

such derivative, silvestrol, has shown activity comparable to taxol in certain settings. Here, we report the synthesis of various rocaglamide analogues and identification of a hydroxamate derivative (−)-9 having activity similar to silvestrol in vitro and ex vivo for inhibition of protein synthesis. We also show that (−)-9 synergizes with doxorubicin in vivo to reduce Eμ-Myc driven lymphomas.
