For the first time, callus and suspension cultures of Linum linearifolium were initiated. Podophyllotoxin (PTOX), a strong antitumor precursor, was isolated from the calli and suspension, as a main lignan besides smaller amount of 6-methoxypodophyllotoxin (6MPTOX). L. linearifolium is now the third Linum species of section Syllinum, with PTOX as the main(More)
BACKGROUND Arylnaphthalene lignan Justicidin B is a lead compound in the management of bone cancer and osteoclastogenesis. The compound is the main cytotoxic principle of rare medicinal plant Linum narbonense L. (Linaceae). However, there have been no reports on the bioreactor production of justicidin B. OBJECTIVE to develop cost-effective biotechnology(More)
Purpose of work: The study was aimed to assess the antineoplastic activity of justicidin B in vitro and to search for its general toxicological profile in vivo. The anti-neoplastic activity of the arylnaphthalene lignin, justicidin B, was assessed in a panel of human lymphoma cell lines and compared with etoposide as a reference compound. A screening of the(More)
