 Flavone C-glycosides from the leaves of Lophatherum gracile and their in vitro antiviral activity.

Abstract
Four new flavone C-glycosides, luteolin 6-C-α-L-arabinopyranosyl-7-O-β-D-glucopyranoside, apigenin 6-C-β-D-galactopyranosiduronic acid (1 → 2)-α-L-arabinopyranoside, luteolin 6-C-β-D-galactopyranosiduronic acid (1 → 2)-α-L-arabinopyranoside, and luteolin 6-C-β-D-glucopyranosiduronic acid (1 → 2)-α-L-arabinofuranoside, along with three known ones, were isolated from the leaves of Lophatherum gracile. The structures of the new compounds were elucidated by extensive spectroscopic methods as well as acid hydrolysis. All the flavone glycosides isolated from this plant were screened for their in vitro antiviral activity against respiratory syncytial virus (RSV) with cytopathic effect (CPE) reduction assay, and several flavone 6-C-monoglycosides showed potent in vitro anti-RSV effect.

Ethanol extract of Lophatheri Herba exhibits anti-cancer activity in human cancer cells by suppression of metastatic and angiogenic potential
Aeyung Kim, Minju Im, Min Jung Gu & Jin Yeul Ma
Abstract
Lophatheri Herba (LH), dried leaf of Lophatherum gracile Brongn, has long been used to reduce thirst and treat fever and inflammation in Chinese medicine. Recent studies have shown that LH has anti-viral, anti-bacterial, anti-cancer, anti-oxidant, diuretic, and hyperglycemic properties. However, the effects of an ethanol extract of L. herba (ELH), at non-cytotoxic doses, on the metastatic and angiogenic abilities of malignant tumor cells have not been reported. We found that ELH significantly suppressed p38, JNK, and NF-κB activation and proteolytic activities under phorbol 12-myristate 13-acetate (PMA) stimulation, thus leading to a decrease in metastatic potential, including migration and invasion. In addition, ELH suppressed tumor-induced angiogenesis, including migration and tube formation in human umbilical vein endothelial cells (HUVECs) and microvessel sprouting from aortic rings via decreasing the pro-angiogenic factors in tumors. Interestingly, in ovo xenografts ELH-treated HT1080 cells did not increase in volume and eventually disappeared, owing to a lack of angiogenesis. Daily oral administration of ELH at 50 and 100 mg/kg markedly inhibited metastatic colonization of B16F10 cells in the lungs of C57BL/6J mice and caused no apparent side effects. These data collectively indicate that ELH is safe and may be useful for managing metastasis and growth of malignant cancers.
