(Lagerstroemia speciosa L.)提取物已被用作传统药物,可有效控制糖尿病和肥胖症。这项研究的目的是评估抗HIV Property of the extracts prepared from the leaves and stems of banaba, and further purification and characterization of the active components.
METHODS: Aqueous and 50 per cent ethanolic extracts were prepared from leaves and stems of banaba and were evaluated for cytotoxicity and anti-HIV activity using in vitro reporter基于基因的测定法。此外,使用硅胶柱色谱法从Banaba叶的50%乙醇提取物中分离出三种化合物,并通过HPLC,NMR和MS分析进行表征。 To delineate the mode of action of the active compounds, reverse transcriptase assay and protease assay were performed using commercially available kits.
RESULTS: All the extracts showed a dose dependent inhibition of HIV-1-infection in TZM-bl and CEM-GFP cell lines with a maximum from the 50 per cent叶片中的乙醇提取物(IC 50 = 1至25μg/ml)。当用提取物处理时,通过感染的CEM-GFP细胞中的病毒负荷(P24)估计来证实这一观察结果。食道酸显示逆转录酶的抑制作用,而椭圆酸抑制了HIV-1蛋白酶活性。
解释和结论: 本研究显示,本研究显示了Banaba的新型抗HIV活性。通过抑制逆转录酶和HIV蛋白酶的抑制作用,负责抗HIV活性的活性成分是食道酸和椭球酸,因此可以被视为有希望的候选者来发展局部抗HIV-HIV-1代理。
