METHODS:Film dispersion method and ammonium sulfate gradient method were used to prepare the vinorel-bine-tetrandrine liposomes modified with RGD,and the morphology and particle size distribution were observed. The vinorelbine content was determined,and sulforhodamine B method was used to respectively determine the inhibitory effects of blank targeting liposomes,normal vinorelbine liposomes and vinorelbine-tetrandrine liposomes modified with RGD on C6 cells. RESULTS:The prepared vinorelbine-tetrandrine liposomes modified with RGD were spherical or almost spherical with smooth surface,and particle size was about 120 nm. The average content of vinorelbine was 28.27 μg/mL(RSD=0.38%,n=3). Blank targeting liposomes had no significant effect on the growth of C6 cells;vinorelbine-tetrandrine liposomes modified with RGD can obviously inhibit the growth of C6 cells,and cell viability after its effect was significantly lower than normal vinorelbine liposomes (P<0.05). CON-CLUSIONS:Vinorelbine-tetrandrine liposomes modified with RGD are successfully prepared,and they show obvious inhibitory ef-fects on the growth of C6 cells.

    • 摘要: OBJECTIVE: To prepare Vinorelbine liposomes (VRB) and to investigate their tissue distribution in mice. METHODS: Vinorelbine liposomes were prepared by film-dispersion method. Lewis lung carcinoma C57BL/6J tumor-bearing mice were divided into control group (VRB injection) and liposomes group (VRB liposomes) with each group of 24 mice. Those mice were given relevant medicine 10 mg·kg-1 via tail vein. Sampling was scheduled at 0.5, 2.0 and 12.0 h, and HPLC method was performed to determine the drug concentration in plasma, heart, liver, spleen, lung, kidney, muscle, brain and tumor. The drug targeting index was computed finally. RESULTS: Mean particle size of VRB liposomes was 158.3 nm. VRB liposomes were complete round in appearance and uniform in size with obvious bi-layer. Compared with control group, Vinorelbine liposomes were distributed mainly in liver, spleen and tumor in mice (P<0.05 or P<0.01). No obvious change was found in other tissues. Obvious targeting of VRB liposomes to liver, spleen, tumor and some targeting of it to lung were observed. CONCLUSIONS: Prepared VRB liposomes have obvious targeting to the tumor of lung carcinoma model mice.%目的:制备异长春花碱(VRB)脂质体并考察其在小鼠体内的组织分布情况.方法:采用薄膜分散法制备VRB脂质体;以Lewis肺癌C57BL/6J荷瘤小鼠为模型,分为对照组(VRB注射液)和脂质体组(VRB脂质体),每组24只,分别尾静脉注射10 mg·kg-1,于给药后0.5、2.0、12.0h取样,以高效液相色谱法测定各组小鼠不同时间血浆、心、肝、脾、肺、肾、肌肉、大脑、肿瘤中的药物浓度,并计算制剂的靶向性参数.结果:制备的VRB脂质体的平均粒径为158.3 nm,脂质体外观圆整、大小均匀,可见明显的双分子层结构;与VRB注射液比较,VRB脂质体在模型小鼠肝、脾、肿瘤中3个时间点的分布均明显增强(P<0.05或P<0.01),其余组织分布无明显变化;VRB脂质体对模型小鼠具有明显的肝、脾、肿瘤靶向性及一定的肺靶向性.结论:所制备的VRB脂质体对肺癌模型小鼠肿瘤组织具有明显靶向性.
