Abstract:
(EN)
The present invention provides a polymer DDS which enables the controlled release of a drug having a carboxyl group. A drug-conjugated block copolymer according to the present invention is represented by the general formula: A-B. In the general formula, A represents a polyethylene glycol chain segment; and B represents a copolyamino acid chain segment containing a repeating unit represented by general formula (i) and/or (ii), wherein X in each of formulae (i) and (ii) represents a residue of the drug and the residue may have a linking group.
(FR)
L'invention concerne un système d'administration de médicaments (DDS) polymère permettant la libération contrôlée d'un médicament contenant un groupe carboxyle. Le copolymère séquencé conjugué à un médicament selon l'invention est représenté par la formule générale : A-B. Dans la formule générale, A représente un segment de chaîne de polyéthylène glycol ; et B représente un segment de chaîne de copolyamino acide contenant une unité récurrente représentée par la formule générale (i) et/ou (ii), dans lesquelles X représente un résidu du médicament, ce résidu pouvant contenir un groupe de liaison.
(JA)
本発明は、カルボキシル基を有する薬物の放出制御を可能にするポリマーDDSを提供する。本発明の薬物複合化ブロック共重合体は、一般式A-Bで表される。Aは、ポリエチレングリコール鎖セグメントを表し、Bは、下記一般式(i)および/または(ii)で表される繰り返し単位を含むコ-ポリアミノ酸鎖セグメントを表し、式(i)および(ii)中のXは、連結基を有していてもよい薬物の残基を表す。
