  • Patent number: 8815913
    Abstract: Polypeptides of formula (I): wherein R1 and R2 are substituents independently selected from substituted and un-substituted alkyl groups and substituted and un-substituted aryl groups, and n is an integer greater than or equal to 2. Synthesis methods are also provided that do not use amino acids as starting materials, but instead employ imines and carbon monoxide as monomers that undergo transition metal-catalyzed alternating copolymerization to directly provide polypeptides using an acylcobalt catalyst with the following structural formula: wherein R is selected from the group consisting of alkyl, phenyl, and substituted phenyl groups.
    Type: Grant

  • Publication number: 20100087523
    Abstract: Rupestonic acid derivatives are rupestonic acid derivative A- or B-type compounds, prepared through a condensation reaction from starting materials, i.e., a monomer compound of rupestonic acid and an aromatic amine or fatty amine or an organic alcohol, i.e., a fatty alcohol or an aromatic alcohol. Rupestonic acid, which is the monomer compound of sesquiterpene isolated from the plant Xinjiang Artemisia rupestric L., is used as a mother compound. Natural anti-virus lead compound with high activity are discovered by modifying the structure of the monomer compound of rupestonic acid. Activity results of the lead compound showed pharmaceutical application of anti-I, II flu virus and anti-I, II herpes simplex virus infection. These compounds can be used alone or in combination with one or more pharmaceutical acceptable, inert and nontoxic excipients or carries in a pharmaceutical composition.
