- 摘要：
PROBLEM TO BE SOLVED: To provide a carrier for delivering a medicine, capable of more efficiently delivering a medicinal compound to a target site and to provide a medicine complex using the carrier.
SOLUTION: The carrier for delivering the medicine is obtained by using a polyether including structural units represented by formulas (I), (II) and (III), and having 1,000-200,000 weight average molecular weight expressed in terms of polyethylene glycol (PEG). The medicine complex uses the carrier. (In the formulas, R
1 is hydrogen, sodium or a group having pharmacologic action with the proviso that R1 s can be the same or different in the same copolymer). [The molar ratio of each structural unit satisfies the equation: (I)/((I)+(II)+(III))=0.001-0.5 and the mol% of each of units (I), (II) and (III) is (I)=0.01-99.98 mol%, (II)=0.01-99.98 mol%, or (III)=0.01-99.98 mol%].COPYRIGHT: (C)2006,JPO&NCIPI
