picropodophyllotoxin/podophyllum

Esophageal squamous cell carcinoma (ESCC), a major histologic type of esophageal cancer, is one of the frequent causes of cancer-related death worldwide. Picropodophyllotoxin (PPT) is the main component of Podophyllum hexandrum root with antitumor activity via apoptosis-mediated mechanisms in

Two new aryltetralin-type lignans, isopodophyllotoxin 7'-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside (1) and 4-demethyl-picropodophyllotoxin 7'-O-beta-D-glucopyranoside (2), along with eight known podophyllotoxin derivatives: 4-demethyl-podophyllotoxin 7'-O-beta-D-glucopyranoside (3),

4-Demethyl-picropodophyllotoxin 7'-O-beta-D-glucopyranoside (4DPG), a new podophyllotoxin glucoside, was isolated from the rhizomes of Sinopodophyllum emodi (Wall.) Ying and showed cytotoxic effects in human carcinoma cells. Among the target cells (HeLa, A2 and SH-SY5Y), the cytotoxic effects of

The antiviral activity of an aqueous extract of Podophyllum peltatum was investigated. The extract was fractionated by reversed-phase chromatography, and podophyllotoxin was found to be the most active component in inhibiting the replication of measles and herpes simplex type I viruses.
