Development of dual functional liposome has been studied for cancer theragnostics. Therefore, we focused on ultrasound-sensitive liposomes with doxorubicin (DOX) and gadolinium (Gd) as a theragnostic carrier having a potential for cancer therapy and diagnosis. In this study, Gd(III)-DOTA-modified sonosensitive liposomes (GL) was developed using chemically synthesized Gd(III)-DOTA-DPPE lipid. Sonosensitivity
已经研究了用于癌症治疗学的双功能脂质体的开发。因此,我们专注于以多柔比星(DOX)和钆(Gd)作为具有癌症治疗和诊断潜力的治疗载体的超声敏感脂质体。在这项研究中,使用化学合成的 Gd(III)-DOTA-DPPE 脂质开发了 Gd(III)-DOTA 修饰的声敏脂质体 (GL)。GL 对 1 MHz 超声的声敏性诱导了 25% 的 DOX 释放。GL 的弛豫度 () 为 , 高于 MR-bester。根据超声强度评估通过超声照射从 GL 向细胞内递送 DOX,与没有超声的 GL3 或 Doxil 相比,导致从超声触发的 GL 释放的 DOX 的摄取增加。总之,这项研究表明顺磁性和声敏脂质体,
