Abstract:
The present invention provides compositions which allow for the extended release and enhanced bioavailability of biologically-active polypeptides following parenteral delivery to an animal. More particularly, it concerns compositions comprising biologically-active somatotropin formulated for extended release, methods of preparing these compositions, and methods of using the same. These compositions comprise somatotropin, a bioavailability-enhancing constituent (BEC), and a substantially non-aqueous, hydrophobic excipient. The BEC may comprise (i) amino acids or amino acid derivatives, such as histidine-HCl; (ii) hydroxamate derivatives, such as histidine hydroxamate or suberohydroxamic acid; (iii) non-reducing carbohydrates, such as trehalose or trehalose octaacetate; (iv) oxo-acid salts, such as a mixture of monobasic and dibasic sodium phosphate; or (v) a mixture of two or more compounds from within the foregoing classes (i)–(iv).

Abstract:
This invention pertains to a synthetic adhesive composition for use in aqueous environments. The composition comprises polypeptide chains having an .alpha.-helical structure in aqueous environments and capable of cohesive and adhesive interactions. The polypeptide chains comprise polar and apolar amino acids, the apolar and polar amino acids being arranged to define apolar and polar vertical spiraling stripes on the helix surface. The apolar stripes allow the polypeptide chains to aggregate into superhelical structures and the polar stripes allow interchain crosslinking within and between the superhelical structures.
Abstract:
Novel enzyme mutants are disclosed which are derived from a precursor enzyme by replacing or modifying at least one catalytic functional group of an amino acid residue in a precursor enzyme. Such mutant enzymes have a catalytic preference for substrates which provide the replaced or modified catalytic group or its equivalent such that the substrate together with the enzyme mutant assists in its own catalysis.
