从中药厚朴皮中分离鉴定了12个联苯型木脂素, 其中包括一个新的单萜联苯型木脂素薄荷基厚朴酚(menthylmagnolol, 1)和一个新的天然产物和厚朴酚4'-O-β-D-葡萄糖苷(honokiol 4'-O-β-D-glucoside, 9), 此外还包括10个已知联苯型木脂素. 结构通过高分辨质谱及一维/二维核磁共振波谱及圆二色谱等波谱技术得以鉴定, 其中, 化合物1是第2个被报道的单萜单元与联苯单元通过六元环连接的单萜联苯型木脂素. 首次评估了它们对蛋白酪氨酸磷酸酶1B (PTP1B)和幽门螺杆菌的体外抑制活性, 发现化合物3~6对PTP1B具有显著抑制活性, IC50值分别为(9.20±1.95), (9.23±1.12), (8.71±0.54)和(6.90±0.70) μmol/L. 化合物4~610有显著的幽门螺旋杆菌抑制活性, 最低抑菌浓度(MIC)均为500 mg/L. 初步构效关系表明, 薄荷基等单萜基团的引入有利于提高联苯型木脂素的PTP1B酶和幽门螺旋杆菌抑制活性, 结果证实单萜骈联苯型木脂素具有作为抗Ⅱ型糖尿病以及抗幽门螺旋杆菌药物的开发潜力.

Twelve biphenyl lignans including a new monoterpene biphenyl lignan (menthylmagnolol, 1) and a new natural product (honokiol 4'-O-β-D-glucoside, 9), along with ten known ones were isolated from the bark of Magnoliae officinalis. Their structures were elucidated by HRMS and spectroscopic methods including 1D/2D NMR and electronic circular dichroism (ECD) and so on. Compound 1 was the second reported natural monoterpene biphenyl lignan in which the monoterpene unit and biphenyl lignan unit were fused via a six-membered ring. Their in vitro inhibitory activities against protein tyrosine phosphatase 1B (PTP1B) and Helicobacter pylori were evaluated for the first time. Compounds 3~6 showed significant inhibitory activity against protein PTP1B with IC50 values of (9.20±1.95), (9.23±1.12), (8.71±0.54) and (6.90±0.70) μmol/L, respectively. Compounds 4~6 and 10 showed significant anti-Helicobacter pylori activity with minimum inhibitory concentration (MIC) of 500 mg/L. The preliminary structure-activity relationship exhibited that the monoterpene units of biphenyl lignans were probably beneficial to improve the inhibitory activities against PTP1B and Helicobacter pylori. The research results indicate that monoterpene biphenyl lignans have development potential as drugs for treating type II diabetes and Helicobacter pylori infections.
