权利人:ISP INVESTMENTS INC; ISP INVESTMENTS LLC
摘要:Methods for the treatment of irritations of the skin and skin appendages caused by microbial stresses are disclosed. The methods include providing a composition comprising a linseed extract, obtained from hydrolysis of linseed proteins, as an active antimicrobial agent in a physiologically acceptable medium, and topically applying the linseed extract onto the skin in need thereof. The methods may be useful in the cosmetic and pharmaceutical field and, more particularly, in the field of dermatology. Cosmetic methods for reinforcing the chemical barrier function of healthy and/or sensitive skin and skin appendages are also disclosed that include the same or similar composition and steps.

摘要:A process for preparing unique peptide mixtures with a broad range of uses using combinations of natural and non-natural amino acid alkyl ester monomers and specific combinations of these monomers as dimers, trimers and higher oligomers selected from the large group of structural motifs that lead to useful physical and/or biological properties and that have been or may be identified from solid state peptide synthesis, isolation of peptides from natural sources, and production of peptides by recombinant DNA methods, or identification of peptides by recombinant methods such as phage display, the method of peptide synthesis comprising a) admixing one or more natural and non-natural amino acid alkyl ester monomer, dimer, trimer and higher oligomers with one or more proteases in a reaction medium; b) heating the mixture to between about 5° C. to about 90° C. for between 5 minutes and 24 hours; and c) recovering the formed oligopeptide.

摘要:The invention is related to compositions and methods that naturally protect plant tissues against ultraviolet radiation and temperature, thus giving protection against sunburn to plants, plant parts, fruits and/or flowers during their development. The invention is also related to compositions and methods to naturally improve the color of plants, plant parts, fruits and/or flowers by inducing the natural synthesis of flavonoids and anthocyanins present in plants. Likewise, the present invention is directed to improving the nutritional value of plants, plant parts, fruits and/or flowers by increasing the normal levels of polyphenolic compounds, especially flavonoids, present therein. Additionally, the present invention is related to compositions and methods that give more resistance to plants, plant parts, fruits and/or flowers against pathogens as bacteria and fungi. Finally, the present invention is related to plants, plant parts, fruits, flowers and/or propagating material treated with the compositions described in the present document.

摘要:A composition for treating damaged tissue and promoting healthy tissue growth, healing and tissue regeneration, wherein the composition comprises an extracellular matrix compound, a surface-active lipid, one or more enantiomericaily pure L-amino acids or glycine, a hydrophilic surfactant with a high HLB, as well as vitamins, minerals or trace elements. Not only does it maintain good health, but the components are non-intrusive, bio-safe, non-coalescent and can mimic normally occurring stem-cells within a body. When applied to diseased tissues, the subject compositions can stimulate, facilitate, and accelerate protein synthesis for the regeneration of diseased organs and tissues. The healing efficacy of these tissue components gives us further appreciation of the protective action of human tissue over and above and other than the immune protective system or perhaps an integral component part of the immune system.

摘要:An enzymatic synthesis and composition of oligomers and co-oligomers comprised of α-hydroxy carboxylic acids and α-amino acids or peptides is disclosed. In a preferred embodiment, a α-hydroxy carboxylic acid with a specific chiral configuration is linked by an amide linkage to a α-amino acid specific with a specific chiral configuration or linked by an amide linkage to a peptide made up of α-amino acid monomers having identical chiral configurations. Proteolytic enzymes catalyze oligomerization of the α-hydroxy carboxylic acid and α-amino acid. The degree and distribution of oligomerization varies upon the type and concentrations of different reaction mixtures utilized and upon the length of allowed reaction time. The resultant oligomers may be provided to animals such as ruminants as bioavailable amino acid supplements that are resistant to degradation in the rumen and other animals such as swine, poultry and aquatic animals.
