The antiviral activity of 13(E)-labd-13-ene-8alpha,15-diol (1), isolated from Brachyglottis monroi, was examined against human rhinovirus 2 (HRV2) and 3 (HRV3), and the anticancer activity on human cancer cells (A549 and Hep2). Compound (1) showed strong anti-HRV2 and HRV3 activity with a 50% inhibitory concentration (IC(50)) of 2.68 and 0.87 microg/mL, respectively, and a 50% cytotoxicity concentration (CC(50)) of 59.45 microg/mL. Ribavirin only showed anti-HRV3 activity with an IC(50) of 30.48 microg/mL and a CC(50) > 100 microg/mL. The addition of compound (1) to HRV-infected HeLa cells directly reduced the formation of visible cytopathic effect (CPE) and it directly interacted with HRV particles. Furthermore, A549 and Hep2 cells incubated with 32 microg/mL of compound (1) for 48 h exhibited antilung and antilaryngeal cancer activities, with a viability of less than 50%. These results suggest that compound (1) may be used as a potential antiviral and anticancer agent.
从 Brachyglottis monroi 中分离得到的 13(E)-labd-13-ene-8alpha,15-diol(1)具有抗病毒活性,针对人鼻病毒 2(HRV2)和 3(HRV3)进行了检测,同时对人癌细胞(A549 和 Hep2)也进行了抗癌活性检测。化合物 1 对 HRV2 和 HRV3 表现出很强的抑制活性,半数抑制浓度(IC50)分别为 2.68 和 0.87 μg/mL,细胞毒性浓度(CC50)为 59.45 μg/mL。利巴韦林仅对 HRV3 表现出抗病毒活性,IC50 为 30.48 μg/mL,CC50 >100 μg/mL。将化合物 1 添加到 HRV 感染的 HeLa 细胞中可直接减少可见细胞病变效应(CPE)的形成,并且它可以直接与 HRV 颗粒相互作用。此外,用 32 μg/mL 的化合物 1 孵育 A549 和 Hep2 细胞 48 h 后,表现出抗肺癌和抗喉癌活性,细胞活力低于 50%。这些结果表明,化合物 1 可能被用作潜在的抗病毒和抗癌剂。
