Auristatins, synthetic analogues of the antineoplastic natural product Dolastatin10, are ultrapotent cytotoxic microtubule inhibitors that are clinically used as payloads in antibody–drug conjugates (ADCs). The design and synthesis of several new auristatin analogues with N-terminal modifications that include amino acids with α,α-disubstituted carbon atoms are described, including the discovery of
The present invention relates to chirally controlled oligonucleotides, chirally controlled oligonucleotide compositions, and the method of making and using the same. The invention specifically encompasses the identification of the source of certain problems with prior methodologies for preparing chiral oligonucleotides, including problems that prohibit preparation of fully chirally controlled compositions, particularly compositions comprising a plurality of oligonucleotide types. In some embodiments, the present invention provides chirally controlled oligonucleotide compositions. In some embodiments, the present invention provides methods of making chirally controlled oligonucleotides and chirally controlled oligonucleotide compositions.
The present invention relates to cryptophycin compounds, to new cryptophycin payloads, to new cryptophycin conjugates, to compositions containing them and to their therapeutic use, especially as anticancer agents.
