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.

Disclosed herein are methods for the selective substitution of a hydrogen bonded to a carbon atom (e.g., a hydrogen of an aliphatic methylene group) of a compound, which comprise contacting the compound with a substituent in the presence of a BesD halogenase.
The present invention provides compounds of formula M-L-M′ (where M and M′ are each independently a monomeric moiety of Formula (I) and L is a linker). The dimeric compounds have been found to be effective in promoting apoptosis in rapidly dividing cells.

The present invention relates to a ligand-drug conjugate including a ligand; a linker that is connected to the ligand by a covalent bond and has a tris structure represented by a specific structural formula; and an active agent connected to the linker by a covalent bond. In the ligand-drug conjugate, the active agent is bound by the tris structure of the linker, and thus a greater number of active agents can be connected through one linker. Accordingly, a greater number of active agents per antibody binding can be delivered to the target cell, and the drug and/or toxin can stably reach the target cell and effectively exert the drug efficacy.
Halogenated amidino amino acid derivatives of Formula (I) or a pharmaceutically acceptable salt thereof, useful as nitric oxide synthase inhibitors wherein all substituents are described in the specification.
