  • Publication number: 20040171534
    Abstract: The present invention relates to chimeric fatty body-GRF analogs with increased biological potency, their application as anabolic agents and in the diagnosis and treatment of growth hormone deficiencies. The chimeric fatty body-GRF analogs include an hydrophobic moiety (tail), and can be prepared, either by anchoring at least one hydrophobic tail to the GRF, in the chemical synthesis of GRF. The GRF analogs of the present invention are biodegradable, non-immunogenic and exhibit an improved anabolic potency with a reduced dosage and prolonged activity.

  • Patent number: 6762160
    Abstract: This invention relates to compositions for removing biofilms from contaminated surfaces. The compositions minimally comprise a detergent and a salt or a salt-forming acid. Preferably, the compositions comprise a detergent and a salt-forming acid, to provide salts and acids in equilibrium, in such a way that the biofilm is rapidly dismantled and removed in such an environment. The compositions may also comprise a bactericide, for destroying bacteria.

  • Publication number: 20030204063
    Abstract: The present invention is concerned with modified biological peptides providing increased potency, prolonged activity and/or increased half-life thereof. The modification is made via coupling through an amide bond with at least one conformationally rigid substituent, either at the N-terminal of the peptide, the C-terminal of the peptide, on a free amino or carboxyl group along the peptide chain, or at a plurality of these sites. Those peptides exhibit clinical usefulness for example in treating states of insulin resistance associated with pathologies such as type II diabetes.
