It is generally accepted that the origin of the cytotoxicity of ent-kaurane diterpenoids is due to the formation of reactive oxygen species (ROS) and that the α,β-unsaturated carbonyl is a pivotal moiety. Herein we demonstrate the isolation of 32 new and 12 known ent-kaurane diterpenoids from two

Microtubules are long-standing targets in cancer chemotherapy. Previously, we reported that marchantin C triggers apoptosis of human tumor cells. We show here that marchantin C induced cell cycle arrest at G(2)/M phase in A172 and HeLa cells. In addition, marchantin C decreased the quantity of

Rosmarinic acid (RA) is a highly valued natural phenolic compound that is very commonly found in plants of the families Lamiaceae and Boraginaceae, including Coleus blumei, Heliotropium foertherianum, Rosmarinus officinalis, Perilla frutescens, and Salvia officinalis. RA is also found in other

Apigenin, a widely distributed flavone, exhibits excellent antioxidant, anti-inflammatory, and antitumor properties. In addition, the methylation of apigenin is generally considered to result in better absorption and greatly increased bioavailability. Here, four putative Class II methyltransferase

An endophytic fungus Chaetomium fusiforme was obtained from a liverwort, Scapania verrucosa. A comparison of the constituents of the ether extracts between S. verrucosa and the C. fusiforme culture was investigated by gas chromatography-mass spectrometry (GC/MS). The yield of ether extract based on

Some diterpenoids show various biological activities, including anti-inflammatory, anti-HIV and anti-tumor activity. Previously, we have focused our research on the apoptosis-inducing properties of diterpenoids and found that some ent-kaurene-type diterpenoids induced apoptosis in human leukemia

Riccardin D is a novel macrocyclic bisbibenzyl compound extracted from Chinese liverwort plant Dumortiera hirsuta. Our previous studies showed that riccardin D is a DNA topo II inhibitor and has therapeutic potential for treatment of cancers. In this combined in vitro and in vivo study, we examined

Liverwort constituents have been reported to exert a broad spectrum of biological activities. In this study, we used a bioactivity-guided separation of an extract from the liverwort species Marchantia emarginata subsp. tosana to determine its anticancer activity. A high level of the active

Riccardin F and pakyonol, macrocyclic bisbibenzyls from Plagiochasm intermedium, have been confirmed to possess antifungic activities against Candida albicans. Herein, we evaluated their anti-tumor activity in vitro by employing K562 and K562/A02 cells, the well-known adriamycin (ADR)-induced

The study aimed to investigate the phytochemical contents, antioxidant and antiproliferative activity of 80% methanol extract of Lepidozia borneensis. The total phenolic and total flavonoid contents were analysed using Folin-Ciocalteu and aluminium chloride colorimetric methods. Antioxidant

The present study was designed to investigate the pharmacokinetics following oral and intravenous administration of Riccardin D, an anticancer drug candidate isolated from Chinese liverworts Dumortiera hirsute, in Wistar rats. An HPLC-MS/MS analytical method was developed and validated. The results

Recently, remarkable microtubule inhibitor and anti-tumor activities of the bis(bibenzyl) marchantin C--isolated from liverworts like Marchantia polymorpha since 1983--were found. In this paper we describe the efficient total synthesis of this subtype of bis(bibenzylic) compounds with two

Genistein (4',5,7-trixydroxyflavone) is a member of the family of plant flavonoids that widely occurs in crop plants. It is involved in a wide spectrum of pharmacological activities, and is suggested to have anti-cancer dietary properties. Cell membranes are one of the targets of anti-cancer drugs.

P-glycoprotein (P-gp) is known to mediate multidrug resistance (MDR) by acting as an efflux pump to actively transport chemotherapeutic agents out of carcinoma cells. Inhibition of P-gp function may represent one of the strategies to reverse MDR. We have previously reported that marchantin C (MC), a

Riccardin D, a liverwort-derived naturally occurring macrocyclic bisbibenzyl, has been found to exert anticancer effects in multiple cancer cell types. In this study, we investigated the effect and mechanism of Riccardin D on human breast cancer. Experiments were performed on human breast cancer
