Yan ZHANG, Yuqi XIAN, Leiqiong GAO, et al. Comparison of inhibitory effects of 4 effective components of traditional Chinese drugs on
目的
2
利用沙眼衣原体(
Chlamydia trachomatis
Ct)菌株Ct-L2/PompA-GFP,快速筛查黄连素、雷公藤红素、黄芩苷、三羟黄酮体外抑制Ct作用。
方法
2
通过CCK-8检测药物细胞毒性作用,得出50%细胞毒性药物浓度(50% cytotoxic concentration,CC50);通过菌株Ct-L2/PompA-GFP快速筛查四种中药体外抑制Ct的效果,得出50%抑制率药物浓度(50% inhibitory concentrations,IC50);使用治疗指数(therapeutic index,TI)综合评估药物安全性和有效性。选择安全药物浓度(≥90%细胞存活率),通过活细胞实时观察、免疫荧光染色和末端包涵体形成单位测定,再次确认药物的细胞毒性和体外抑制Ct作用。
结果
2
黄连素、雷公藤红素、黄芩苷、三羟黄酮的CC50(mean±SD)分别为(97.0±2.2)、(2.0±0.08)、(557.1±29.1)、(205.8±9.1);IC50(mean±SD)分别为(2.73±0.09)、(0.60±0.02)、(260.0±10.2)、(60.9±3.8);TI分别为35.5、3.3、2.1、3.4,提示黄连素更安全有效。黄连素、雷公藤红素、黄芩苷、三羟黄酮安全药物浓度分别为10.0、0.2、80.0、10.0 μmol/L,结果显示黄连素具有明显的Ct抑制作用(
P
<0.000 1),其他3种药物无明显抑制Ct作用。
结论
2
黄连素可能成为抑制Ct安全有效的药物。
Objective
2
To compare the inhibitory effects of the effective components derived from 4 traditional Chinese drugs
namely berberine (BER)
celastrol (CEL)
baicalin
and baicalein
on
Chlamydia trachomatis
(Ct) Ct-L2/PompA-GFP strain
in vitro
.
Methods
2
CCK-8 assay was used to determine the 50% cytotoxic concentration (CC50) of the 4 agents in human cervical cancer HeLa 229 cells according to the dose-cytotoxicity curve. The inhibitory effect of each agent on Ct was estimated by observing the decrease in GFP intensity
and the 50% inhibitory concentration (IC50) of each agent was calculated based on the dose-inhibition curve. The therapeutic index (TI) was used to assess both the safety and efficacy of the 4 agents. Using the safe drug concentration (defined as a ≥90% cell viability in HeLa 229 cells)
the safety and efficacy of the agents for inhibiting Ct were further assessed by observing the live cells
immunofluorescence assay (IFA) and endpoint inclusion-forming unit assay (IFUs).
Results
2
The CC50s of BER
CEL
baicalin and baicalein were 97.0±2.2
2.0±0.08
557.1±29.1
and 205.8±9.1
respectively and their IC50s were 2.73±0.09
0.60±0.02
260.0±10.2
and 60.9±3.8
respectively. The TIs of BER
CEL
baicalin and baicalein were 35.5
3.3
2.1
and 3.4
respectively
showing a better safety and a stronger efficacy of BER among the 4 agents. The safe concentrations of BER
CEL
baicalin and baicalein in HeLa 229 cells were 10
0.2
80
and 10 μmol/L
respectively. The results showed that BER could markedly inhibit Ct (
P
<
0.0001)
while the other 3 agent did not produce obvious inhibitory effect on Ct.
Conclusion
2
BER can obviously inhibit Ct
in vitro
and may serve as a potent anti-chlamydia drug with a good safety profile.
