摘要:
A two-chain insulin analogue contains an A chain modified by (i) a monomeric glucose-binding element at or near its N terminus and (ii) a B chain modified by at or near its C terminus by an element that reversibly binds to the monomeric glucose-binding element such that this linkage is displaceable by glucose. The monomeric glucose-binding element may be phenylboronic acid derivative (optionally halogenated). The B chain may be modified by a diol-containing element derived from a monosaccharide, disaccharide or oligosaccharide, a non-saccharide diol-containing moiety or a α-hydroxycarboxylate-containing moiety. The analogue can be manufactured by trypsin-mediated semi-synthesis. Formulations can be at strengths U-10 to U-1000 in soluble solutions at pH 7.0-8.0 with or without zinc ions at a molar ratio of 0.0-3.0 ions per insulin analogue monomer. A patient with diabetes mellitus may be treated with subcutaneous, intraperitoneal, or oral administration of a physiologically effective amount of the insulin analogue.

摘要:
A polypeptide comprises an insulin B-chain sequence having the substitutions: Asp at position B10, Ala at position B12, and Glu at position B29, relative to wild type insulin. The polypeptide may additionally comprise a substitution of a halogenated phenylalanine at position B24, such as ortho-fluoro-phenylalanine. Optionally, the polypeptide may additionally comprise a C-terminal dipeptide extension wherein at least one amino acid in the dipeptide contains an acidic side chain, such as Glu-Glu, and/or an N-terminal deletion of one, two or three residues from the B chain. An insulin analogue may comprise any of these polypeptides with an insulin A-chain polypeptide that optionally contains a Glu A8 substitution. The A-chain sequence may be a separate polypeptide or it may be joined to the B-chain polypeptide by a two amino acid linker. The linker may be Trp-Lys or Ala-Lys. The insulin analogue may be used to treat a patient with diabetes mellitus.
