    摘要: The invention provides compositions of novel high penetration compositions (HPC) or high penetration prodrugs (HPP) of peptides and peptide-related compounds, which are capable of crossing biological barriers with high penetration efficiency. The HPPs are capable of being converted to parent active drugs or drug metabolites after crossing the biological barrier and thus can render treatments for the conditions that the parent drugs or metabolites can. Additionally, the HPPs are capable of reaching areas that parent drugs may not be able to access or to render a sufficient concentration at the target areas and therefore render novel treatments. The HPPs can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.

    摘要: An eye drop containing (i) a peptide having an amino acid sequence which is represented by Ser-Ser-Ser-Arg (“SSSR”), or a pharmaceutically acceptable salt thereof and (ii) a peptide having an amino acid sequence represented by Phe-Gly-Leu-Met-NH2 (“FGLM”), or a pharmaceutically acceptable salt thereof. The concentration ratio of the SSSR or a pharmaceutically acceptable salt thereof and the FGLM or a pharmaceutically acceptable salt thereof is 1/15 and 1/50. The concentration of the SSSR or a pharmaceutically acceptable salt thereof is 0.001% to 0.3% (w/v), and the concentration of the FGLM or a pharmaceutically acceptable salt thereof is 0.015% to 1.5% (w/v). The pH of the eye drop is 2.5 to 6.5. The eye drop serves to minimize the occurrence of side effects and serves to improve its storage stability.

    摘要: The invention provides compounds and methods, for example, to carry out organocatalytic Michael additions of aldehydes to cyclically constrained nitroethylene compounds catalyzed by a proline derivative to provide cyclically constrained α-substituted-γ-nitro-aldehydes. The reaction can be rendered enantioselective when a chiral pyrrolidine catalyst is used, allowing for Michael adducts in nearly optically pure form (e.g., 96 to >99% e.e.).The Michael adducts can bear a single substituent or dual substituents adjacent to the carbonyl. The Michael adducts can be efficiently converted to cyclically constrained protected γ-amino acid residues, which are essential for systematic conformational studies of γ-peptide foldamers. New methods are also provided to prepare other γ-amino acids and peptides. These new building blocks can be used to prepare foldamers, such as α/γ-peptide foldamers, that adopt specific helical conformations in solution and in the solid state.
