멀티 암(multi-arm)이며, 수용성(水溶性) 폴리머로 수식(修飾)된 표적 약물 콘쥬게이트이며, 구조식(III)으로 표시되는 구조를 가지는 약물 콘쥬게이트에 관한 것이다. (식 중, R은 유기 중심이며, POLY는 폴리머이며, L은 다가 링커이며, T는 표적 분자이며, D는 캠토테신계 약물이며, q는 3〜8이 임의의 정수이다.) 상기 약물 콘쥬게이트는, 캠토테신계 약물의 좋지 못한 수용성, 높은 독성, 및 낮은 바이오 어베일러빌리티(availability)를 개선할 수 있다.
ved prodrugs, in which the phenolate group was modified with a variety of hydrophobic moieties. This esterification fine‐tuned the polarity of the SN‐38 molecule and enhanced the lipophilicity of the formed prodrugs, thereby inducing their self‐assembly into biodegradable poly(ethylene glycol)‐block‐poly(d,l‐lactic acid) (PEG‐PLA) nanoparticulate structures. Our strategy combining the rational engineering
