Abstract:
The invention provides combretastatin A-4 like compounds that are modified to have enhanced tubulin binding activity and in some embodiments the ability to promote accumulation in the vasculature undergoing angiogenesis (homing activity). The compounds are based on the combretastatin A-4 skeletal structure having a tubulin-binding pharmacophore comprising two fused rings (A and B rings) in which the B ring is substituted with (a) an aromatic ring structure (C ring) and (b) a second substituent/functional group that comes off the B ring. The aromatic ring structure is typically a six membered ring phenolic or aniline structure, or may also be a fused ring structure such as a substituted or unsubstituted naphthalene. The second substituent on the B ring may for example be a substituent which has been found to provide enhanced tubulin binding activity (for example a carbonyl group), or may be a substituent that facilitates functionalisation of the B ring (for example an hydroxyl or amine group), or it may be a binding agent for a target that is preferentially expressed on vasculature undergoing angiogenesis, and not expressed on quiescent vasculature.
Abstract:
Disclosed herein are non-natural amino acids and polypeptides that include at least one non-natural amino acid, and methods for making such non-natural amino acids and polypeptides. The non-natural amino acids, by themselves or as a part of a polypeptide, can include a wide range of possible functionalities, but typical have at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Also disclosed herein are non-natural amino acid polypeptides that are further modified post-translationally, methods for effecting such modifications, and methods for purifying such polypeptides. Typically, the modified non-natural amino acid polypeptides include at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Further disclosed are methods for using such non-natural amino acid polypeptides and modified non-natural amino acid polypeptides, including therapeutic, diagnostic, and other biotechnology uses.

Abstract:
Certain known and novel pyruvate derivatives are particularly active in restoring or preserving metabolic integrity in oxidatively competent cells that have been subjected to oxygen deprivation. These pyruvate-derived compounds include, but are not limited to oximes, amides, pyruvate analogues, modified pyruvate analogues, esters of pyruvate (e.g., polyol-pyruvate esters, pyruvate thioesters, glycerol-pyruvate esters and dihydroxyacetone-pyruvate esters). Such pyruvate derivatives (including single tautomers, single stereoisomers and mixtures of tautomers and/or stereoisomers, and the pharmaceutically acceptable salts thereof) are useful in the manufacture of pharmaceutical compositions for treating a number of conditions characterized by oxidative stress.
