We examined the effect of (-)-syringaresinol, a furofuran-type lignan isolated from Daphne genkwa, on cell cycle regulation in HL-60 human promyelocytic leukemia cells in vitro. (-)-Syringaresinol decreased the viability of HL-60 cells by inducing G(1) arrest followed by apoptosis in a dose- and
A new 8,4'-oxyneolignane glucoside 1 has been isolated from the stems of Dendrobium aurantiacum var. denneanum together with six known phenolic glucosides 2−7. The structure of the new compound, including its absolute configuration, was determined by spectroscopic and chemical methods as
BACKGROUND
In medical oncology, multi-drug resistance (MDR) of cancer cells continues to be a major impediment. We are in quest of novel anti-proliferative agents to overcome drug-resistant tumor cells.
METHODS
In the present study, we investigated the cytotoxicity of 7 naturally occurring phenolic
The ethanol extracts of Wikstroemia foetida var. oahuensis and Wikstroemia uva-ursi showed antitumor activity against the P-388 lymphocytic leukemia (3PS) test system One PS-active constituent of both plants was the lignan wikstromol. Several inactive compounds were identified as daphnoretin,
