Description 2-(Hydroxymethyl)anthraquinone exhibits strong activity against Helicobacter pylori ATCC 43504 at 0.01 mg/disc.
In vitro 通过纸盘扩散法和最小抑制浓度(MIC)生物测定法检查了Tabebuia impetiginosa Martius ex DC干燥内皮来源成分对抗幽门螺杆菌ATCC 43504的生长抑制作用。将分离出的化合物的活性与市售的抗幽门螺杆菌药物,包括阿莫西林、甲硝唑和四环素进行了比较。通过光谱分析鉴定出Tabebuia impetiginosa干燥内皮(泰波)的生物活性成分为2-(Hydroxymethyl)anthraquinone、蒽醌-2-羧酸和2-羟基-3-(3-甲基-2-丁烯基)-1,4-萘醌(拉帕霍尔)。在纸盘扩散法检测中,2-(Hydroxymethyl)anthraquinone在0.01 mg/片的剂量下对幽门螺杆菌ATCC 43504显示出强大的活性。蒽醌-2-羧酸、拉帕霍尔和甲硝唑的效果较弱,在0.1 mg/片的剂量下表现出中等抗幽门螺杆菌活性。阿莫西林和四环素是测试中的高效化合物,以0.005 mg/片的剂量显示出高亲和力。2-(Hydroxymethyl)anthraquinone在此剂量下表现出中等活性。而四环素在0.001 mg/片的剂量下仍然具有强活性,阿莫西林在此剂量下活性较弱。
