    摘要: A human prourokinase-like polypeptide having an amino acid sequence represented by the following formula: (Met).Ser1-X156.Y157.Z158- (wherein Met represents an optionally existing methionine, Ser represents serine present at 1-position of the N-terminal, X represents arginine or other amino acid present at 156-position, Y represents proline, glycine, alanine or valine present at 157-position, Z represents lysine or arginine present at 158-position, and the solid line represents the same amino acid sequence as that of corresponding part of natural human prourokinase or human urokinase-like polypeptide wherein lysine at 135-position is replaced by other amino acid than basic amino acids) or having an amino acid sequence substantially the same as this is disclosed. In addition, a DNA segment which codes the above-described polypeptide; a plasmid containing said DNA segment; E. coli transformed by said plasmid; a process for preparing said polypeptide by culturing said E. coli; a medicine containing said polypeptide; use of said polypeptide for prophylaxis or treatment for formation of thrombus; and use of said polypeptide for preparing the medicine for the above purpose are also disclosed.

    摘要: A polyester type polyfunctional macromonomer represented by the general formula (I):

    wherein R¹ represents a hydrogen atom or an alkyl group having from 1 to 6 carbon atoms, X represents a hydrogen atom, a halogen atom, a cyano group, an alkyl group having from 1 to 6 carbon atoms or a phenyl group, A represents an aliphatic polyester chain, m is 0 or 1, and p, which may be the same or different in each branched chains, represents an integer of from 0 to 6; a polyester type gel which is obtained by polymerization of the polyester type polyfunctional macromonomer; and a drug release controlling material responsive to changes in temperature comprising the polyester type gel are disclosed. The polyester type gel possesses mechanical properties suitable to various utilities, in particular, as a biodegradable polymeric material having a high tensile elongation. The drug release controlling material has an on-off control function of drug release responsive to changes in temperature depending upon the gel transition of the aliphatic polyester type gel.
