An amphiphilic block copolymer having any one of the formulas D-S-H, S(D)-H, S-H(D), D-S-H-S, D-S-H-S-D, S(D)-H-S, S(D)-H-S(D) or S-H(D)-S is disclosed. S is a hydrophilic block; H is a hydrophobic block; D is a drug molecule; ( ) denotes that the group is bonded directly or indirectly as a side chain or as part of a side chain group to the adjacent group; and the hyphen, "-" (or sometimes "–"), denotes that each of the adjacent S, H or D are linked either directly to one another or indirectly to one another via a linker, additionally wherein the hydrophilic block comprises a first hydrophilic monomer and the hydrophobic block comprises a first hydrophobic monomer and a second hydrophobic monomer.
本发明公开了一种具有以下任一公式之一的两亲性嵌段共聚物:D-S-H,S(D)-H,S-H(D),D-S-H-S,D-S-H-S-D,S(D)-H-S,S(D)-H-S(D)或S-H(D)-S。其中,S是亲水性块;H是疏水性块;D是药物分子;()表示该基团直接或间接地作为侧链或侧链基团之一与相邻基团连接;连字符“-”(有时为“–”)表示相邻的S、H或D之间通过连接基团直接或间接连接在一起。此外,亲水性块包括第一亲水性单体,疏水性块包括第一疏水性单体和第二疏水性单体。
