制备雷公藤甲素-川芎提取物醇传递体(TP-CX@TESs),对其进行质量评价,并考察其体外抗炎效果及作用机制。
方法
2
采用超声注入法制备TP-CX@TESs,以包封率和粒径为评价指标,采用Box-Behnken设计-响应面法优化其处方工艺,并针对最优工艺制备所得TP-CX@TESs进行表征和体外透皮性能评价;利用脂多糖(LPS)诱导RAW264.7细胞炎症模型,在药物干预24 h后,检测细胞上清液中一氧化氮(NO)、白细胞介素-6(IL-6)和肿瘤坏死因子-
α
(TNF-
α
)等炎症因子的释放量,采用蛋白免疫印迹法(Western blot)检测Janus激酶2(JAK2)、信号转导和转录激活因子3(STAT3)和
α
7烟碱型乙酰胆碱受体(
α
7nAChR)蛋白水平的表达,并采用实时荧光定量聚合酶链式反应(Real-time PCR)检测JAK2、STAT3、
α

Box-Behnken设计-响应面法结果提示蛋黄卵磷脂质量分数2.3%、乙醇体积分数30%、聚山梨酯-80-蛋黄卵磷脂(2∶5)为最优制备工艺。微观表征显示,TP-CX@TESs呈类球型结构,粒径为(105.60±3.85) nm,多分散指数为0.19±0.03,Zeta电位为(-15.89±0.98) mV,雷公藤甲素、阿魏酸、藁本内酯的包封率分别为(76.88±4.40)%、(78.84±4.40)%、(65.88±0.06)%。TP-CX@TESs中雷公藤甲素、阿魏酸和藁本内酯体外释放和体外经皮渗透均符合一级动力学模型,呈现一定的缓释特性。RAW264.7细胞实验结果显示,TP-CX@TESs在雷公藤甲素和川芎提取物质量浓度分别为39.00 μg·L
-1
和1.95 mg·L
-1
时,能够显著抑制LPS诱导的NO、TNF-

κ
B mRNA的表达(
P

结论

优选的TP-CX@TESs处方工艺简单可行,制备的样品具有良好的体外释放性能、经皮渗透性及优异的体外抗炎活性,其作用机制与抑制NF-
κ
B有关。
Objective
2
To prepare triptolide-Chuanxiong Rhizoma extract ethanol transfersomes(TP-CX@TESs), conduct its quality evaluation, and investigate its
in vitro
anti-inflammatory efficacy and the underlying mechanisms.
Methods
2
TP-CX@TESs was prepared via the ultrasonic injection method. With encapsulation efficiency and particle size as evaluation indicators, Box-Behnken design-response surface me
thodology(BBD-RSM) was employed to optimize the formulation process. The TP-CX@TESs prepared under the optimal process was characterized and evaluated for
in vitro
transdermal performance. A lipopolysaccharide(LPS)-induced RAW264.7 cell inflammation model was established. After 24 h of drug intervention, the levels of inflammatory factors such as nitric oxide(NO), interleukin-6(IL-6), and tumor necrosis factor-
α
(TNF-
α
) in the cell supernatant were detected. Western blot was used to determine the protein expression levels of Janus kinase 2(JAK2), signal transducer and activator of transcription 3(STAT3), and
α
7 nicotinic acetylcholine receptor(
α
7nAChR), and real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) was applied to measure the mRNA expression levels of JAK2, STAT3, the encoding gene of
α
7nAChR(CHRNA7), and nuclear transcription factor-
κ
B(NF-
κ
B).
Results
2
Results of BBD-RSM showed that the optimal formulation for preparing TP-CX@TESs was as follows:egg yolk lecithin content of 2.3%, ethanol volume fraction of 30%, and ratio of polysorbate-80 to egg yolk lecithin of 2∶5. Microscopic characterization revealed that TP-CX@TESs exhibited a spherical-like structure with a particle size of (105.60±3.85) nm, a polydispersity index of 0.19±0.03, and a Zeta potential of (-15.89±0.98) mV. The encapsulation efficiencies of triptolide, ferulic acid, and ligustilide were (76.88±4.40)%, (78.84±4.40)%, and (65.88±0.06)%, respectively. Both
in vitro
release and transdermal penetration of triptolide, ferulic acid, and ligustilide in TP-CX@TESs all followed the first-order kinetic model, showing a certain sustained-release property. Experimental results in RAW264.7 cells indicated that TP-CX@TESs significantly inhibited the release of NO, TNF-
α
, and IL-6(
P
<
0.01), remarkably upregulated
the protein expression levels of STAT3 and
α
7nAChR(
P
<
0.01), increased the mRNA expression level of CHRNA7, and significantly downregulated the mRNA expression level of NF-
κ
B(
P
<
0.05,
P
<
0.01).
Conclusion
2
The optimized formulation process of TP-CX@TESs is simple and feasible, along with favorable
in vitro
release property, good transdermal permeability, and excellent
in vitro
anti-inflammatory activity, the mechanism is related to the inhibition of NF-
κ
B.
