    摘要: A chiral ligand system for transition or main group metal catalysts is disclosed. These ligands can be readily synthesized using inexpensive amino acids and diamines as starting materials. Several different transition or main group metals have been inserted into the ligands. The ligands have been shown to have a tetradhedral distortion that may contribute to enhanced chiral transfer from the catalyst to the substrate in chemical modifications of olefins and other reactive substrates. These catalysts have been demonstrated to be effective in catalyzing epoxidation of a variety of substrates.

    摘要: Amphipathic glycopeptides, the amino acid sequence of which comprises an N-terminal opioid message sequence, a C-terminal helical address sequence, and a linker sequence between the message sequence and the helical address sequence, where the C-terminal helical address sequence has a length of nine amino acids, and at least one of the amino acid residues of the peptide is glycosylated. The peptides are useful for relieving pain, providing analgesia and treating anxiety, depression, obesity, anorexia nervosa, phobias, schizophrenia, Parkinson's disease and Alzheimer's disease.
