概括

将脂质体向巨细胞增强了体内药物释放,但由于瘤选择性差,并没有改善抗瘤效应. 选择性向与瘤相关的巨细胞对于促进抗癌活性至关重要.

科学领域:

生物医学工程生物医学工程
纳米技术纳米技术
药理学药理学是指药理学的学科.

背景情况:

巨细胞内部化脂质体,帮助药物释放.
巨细胞向脂质体对体内药物释放的影响尚不清楚.

研究的目的:

为了在体内比较细胞向性脂质体和PEGylated脂质体的药物释放.
在4T1乳腺瘤模型中评估巨细胞向脂质体的疗效.

主要方法:

脂质体被修改为1,2-distearoyl酸盐 (PS) 以向巨细胞.
在4T1乳腺瘤携带小鼠中评估了细胞吸收和体内药物释放.

主要成果:

与PEGylated脂质体相比,PS修饰的脂质体显示出增强的巨细胞吸收.
用PS修饰的脂质体在各种组织中增加了药物释放.
尽管瘤药物释放率较高,但PS修饰的脂质体由于快速清除而没有改善抗瘤活性.

结论:

巨细胞向增强体脂体药物释放 in vivo.
增强药物释放不能保证改善抗瘤活性,如果没有瘤选择性.
针对与瘤相关的巨细胞对于有效的癌症治疗至关重要.

关键词:

Modified-Release Drug Delivery Systems: Bioavailability

Modified-Release Drug Delivery Systems: Bioavailability

Modified-release (MR) dosage forms are designed to extend drug release over time, thereby maintaining stable plasma concentrations and reducing dosing frequency. However, their bioavailability is typically below 100% due to incomplete drug release and presystemic metabolism, and limitations in drug permeability across the gastrointestinal epithelium, all of which can restrict the fraction of the drug reaching systemic circulation. Consequently, studying the in vivo bioavailability of MR...
