摘要:
The present invention provides a peptide having a fluoroalkyl group in the side chain. The present invention provides a peptide in which 2 or more amino acids are peptide-bonded in which at least one side chain of an amino acid residue constituting the peptide is represented by the following General Formula (1) [in the formula, Z1 is a divalent, trivalent, or tetravalent linking group other than an alkylene group; Rf is a C1-30 alkyl group substituted with at least two fluorine atoms, -SF5, or -SF4-CR101R102-CR103R104Cl (R101, R102, R103, and R104 are each independently a hydrogen atom, a fluorine atom, or a chlorine atom, and two or more of R101, R102, R103, and R104 are fluorine atoms); n3 is 1, 2, of 3, and the black circle indicates a bonding site].

摘要:
Novel tubulysin derivatives which may be useful as cytotoxic agents to provide therapeutic benefits in the treatment of various types of cancers, alone or as drug conjugates with antibodies are provided. The tubulysin derivatives consist of a tetrapeptide scaffold comprising methyl and ethyl substituted piperidines. The tubulysin conjugates further comprise monoclonal antibody via succinimide linkers.
摘要:
Disclosed herein are non-natural amino acids and dolastatin analogs that include at least one non-natural amino acid, and methods for making such non-natural amino acids and polypeptides. The dolastatin analogs can include a wide range of possible functionalities, but typically have at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Also disclosed herein are non-natural amino acid dolastatin analogs that are further modified post-translationally, methods for effecting such modifications, and methods for purifying such dolastatin analogs. Typically, the modified dolastatin analogs include at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Further disclosed are methods for using such non-natural amino acid dolastatin analogs and modified non-natural amino acid dolastatin analogs, including therapeutic, diagnostic, and other biotechnology uses.
摘要:
The invention relates to methods for effecting qualitative and quantitative changes in the functional moieties expressed at the surface of cells and multi-cellular structures, and functional lipid constructs for use in such methods. In particular, the invention relates to functional lipid constructs and their use in diagnostic and therapeutic applications, including serodiagnosis, where the functional moiety is a carbohydrate, peptide, chemically reactive group, conjugator or fluorophore.
