Phytochemical and biological studies of bryophytes.
The bryophytes contain the Marchantiophyta (liverworts), Bryophyta (mosses) and Anthocerotophyta (hornworts). Of these, the Marchantiophyta have a cellular oil body which produce a number of mono-,… Expand

An ent-kaurene diterpene enhances apoptosis induced by tumor necrosis factor in human leukemia cells.
Some antitumor agents, including tumor necrosis factor-alpha (TNF-alpha) and camptothecin (CPT), often cause resistance of tumor cells to antitumor agents through activation of the nuclear… Expand
