    • 摘要: 番荔枝内酯(annonaceous acetogenins,ACGs)是从番荔枝科番荔枝的种子中提取分离得到的有效部位,对多种肿瘤细胞具有良好的抗肿瘤活性.但溶解度差,毒副作用大,限制了其临床应用.本研究选择泊洛沙姆(Poloshamer-188,P188)作为药物载体,用反溶剂沉淀法制备ACGs纳米混悬剂(ACGs nanosuspensions,ACGs-NSps);动态光散射测量粒径;透射电镜考察形态;高效液相考察载药量和体外药物释放,并对ACGs-NSps的放置稳定性、在不同介质中的粒径变化、溶血性、冻干复溶等进行研究;用MTT法考察纳米混悬剂对肿瘤细胞的生长抑制情况,4T1荷瘤小鼠模型考察其体内抗肿瘤效果.结果表明,ACGs-NSps呈球形,平均粒径169.4±1.25 nm,多分散指数(polydispersity index,PDI)值为0.130±0.020,zeta电位-19.8 mV,载药量为48.18%,室温放置15天粒径未见显著变化,可以用0.5%葡萄糖和2% P188为联合保护剂进行冻干,144 h缓慢释放累积达80.82%.纳米混悬剂在各生理介质可稳定存在,不溶血,既能口服也能静脉注射给药.体外细胞毒性实验中,与ACGs溶液相比,ACGs-NSps对多种肿瘤细胞的生长抑制作用(IC50值)均显著优于ACGs溶液(4T1:0.892±0.124 μg·mL-1和2.495±0.108 μg·mL-1,P<0.05;HeLa:0.747±0.051 μg·mL-1和2.204±0.064 μg·mL-1,P<0.01;HepG2:2.265±0.081 μg·mL-1和4.159±0.071 μg·mL-1,P<0.01;MCF-7:0.473±0.024 μg·mL-1和1.196±0.022μg·mL-1,P<0.05).体内研究表明,ACGs-NSps每天口服给药(3mg·kg-1)抑瘤率(67.23%)优于同剂量油溶液的抑瘤率(53.11%),与隔天静脉注射0.5 mg·mL-1 ACGs-NSps的抑瘤率(70.34%)相当.纳米混悬剂的制备,有效解决了ACGs的溶解性和给药问题.P188是FDA批准的静脉注射辅料,以P188为稳定剂的ACGs纳米粒,有望成为可在临床上应用的抗肿瘤药物.

Methods The MTT assay was used to detect the growth inhibition rates of A549 cells cultured with Bullatacin in different concentrations (6.25, 12.5, 25, 50, 100μg/mL). 25μg/mL Bullatacin was used to culture A549 cells for 0, 12, 24, 48 h. The cell cycle distribution and apoptosis were measured by flow cytemetry. The protein expressions of ERK, JNK, and p38 were studied by Western blot. Results Dosage dependence was obviously showed after the different concentrations of Bullatacin were used to A549, and 25 μg/mL;Bullatacin blocked A549 cell in G0/G1 periods and induced its apoptosis. Compared with the blank group, protein expressions of P-ERK, P-JNK, and P-p38 were all increased by different degrees. Conclusion Bullatacin significantly inhibits the proliferation and induces the apoptosis of A549 cell. Its mechanism is related to activity of MAPK pathway thought the phosphorylation of the three protein kinases by Bullatacin.
