justicidin/leukemia

Justicia procumbens (J. procumbens) is a traditional Chinese herbal medicine which was used for the treatment of fever, pain, and cancer. A compound 6'-hydroxy justicidin B (HJB) isolated from J. procumbens exhibits promising biological properties. However, the mechanism of action and the in vivo

BACKGROUND The present study aimed at optimization of the biotechnological production of the lignan justicidin B by genetically transformed cultures of Linum leonii and the pharmacological evaluation of the pro-apoptotic effects of the compound in HL-60 cells. METHODS A rapidly growing selected root

Callus and hairy root cultures of Linum leonii were established. The genetic transformation in hairy roots was proven by PCR analysis, which showed integration of rol A and rol C genes into the plant genome. Calli and hairy roots accumulate the arylnaphthalene lignan justicidin B as a major

Adverse effects and drug resistance to the current onchopharmacologicals have increased the demand for alternative novel therapeutics. We herein introduce justicidin B, an arylnaphthalen lignan isolated from different plant origins, especially Justicia, Phyllanthus, Haplophyllum and Linum species.

Arylnaphthalene lignan lactones have attracted considerable interest because of their anti-tumor and anti-hyperlipidimic activities. However, to our knowledge, few studies have explored the effects of these compounds on human leukemia cell lines. In this study, five arylnaphthalene lignans including

Justicidin B, an arylnaphthalene lignan, has strong cytotoxicity on chronic myeloid and chronic lymphoid leukemia cell lines. The first report of the production of justicidin B in a Linum species concerned in vitro culture of Linum austriacum. Therefore, culture characterization and presence of
