麦卢卡蜂蜜(MkH),来自新西兰麦卢卡树(Leptospermum scoparium),被认为是一种治疗剂,由于其抗菌,抗氧化,抗真菌,抗病毒,抗炎和伤口愈合活性。在这项研究中,使用RT测定比色试剂盒,根据制造商的说明书进行轻微修改,评估了五种蜂蜜类型(包括MkH)对HIV-1 RT活性的抑制作用。MkH以剂量依赖性方式发挥最强的抑制作用,半数最大抑制浓度(IC 50)约为14.8 mg/mL。此外,在MkH组分中,确定甲基乙二醛(MGO)和2-甲氧基苯甲酸(2-MBA)具有抗HIV-1 RT活性。采用高效液相色谱法(HPLC)和液相色谱-质谱法(LC-MS/MS)鉴定MkH中的MGO和2-MBA。结果表明,MkH对HIV-1 RT活性的抑制作用是由多种具有不同物理和化学性质的成分介导的。
Manuka honey (MkH), derived from New Zealand manuka tree (Leptospermum scoparium), is considered a therapeutic agent owing to its antibacterial, antioxidant, antifungal, antiviral, anti-inflammatory, and wound healing activities. In this study, the inhibitory effect of five honey types, including MkH, on HIV-1 RT activity was evaluated, using an RT assay colorimetric kit, according to the manufacturer’s instructions with slight modifications. MkH exerted the strongest inhibitory effect in a dose-dependent manner, with a half maximal inhibitory concentration (IC50) of approximately 14.8 mg/mL. Moreover, among the MkH constituents, methylglyoxal (MGO) and 2-methoxybenzoic acid (2-MBA) were determined to possess anti-HIV-1 RT activity. MGO and 2-MBA in MkH were identified by High Performance Liquid Chromatography (HPLC) and Liquid Chromatograph - Mass Spectrometry (LC-MS/MS). The findings suggest that the inhibitory effect of MkH on the HIV-1 RT activity is mediated by multiple constituents with different physical and chemical properties.
