The effects of aeration within the range of 0.2-0.5 vvm on transformed and high yielding cell cultures of Linum album were investigated in a 5-L stirred tank bioreactor equipped with low shear Setric impeller. The kinetics of cell growth, substrate utilization, and production of lignans, namely,
A phytochemical study of Linum album (Linaceae), guided by bioassay with the 9KB cell culture, resulted in the isolation of podophyllotoxin and a new lignan, 3'-demethylpodophyllotoxin; alpha-and beta-peltatins were identified by comparative TLC.
As most anticancer drugs are derived from natural sources, the screening of local medicinal flora should be considered a primary step in the search for new sources for antineoplastic agents. In Mexico, more than 6000 medicinal plant species are used for the treatment of various diseases, including
UNASSIGNED
Induction of tetraploidy was performed and podophyllotoxin production increased by upregulating the expression level and enzyme activity of genes related to its biosynthesis in tetraploid compared to diploid Linum album. Linum album is a valuable medicinal plant that produces antiviral
BACKGROUND
Linum usitatissimum L., known as common Flax or linseed, from the family Linnaceae, has long been cultivated in different nations due to its applications in medicine and industry. The present study aims to collect nearly all available information about chemical constituents of Flax, as
Background: Linum usitatissimum seed essential oil (LSEO) has been used to reduce the risk of prostate and colon cancer. In this study, we optimized the bio-accessibility and bio-compatibility of LSEO to evaluate its cytotoxic,
Unique plant-derived cyclic peptides family exhibiting various key biological activities has great possibility for anticancer therapy. In this study, we investigated the effects of orbitides isolated from flax (Linum usitatissimum L.) on the growth of SGC-7901 cancer cells and the potential
The analysis of experimental, clinical and epidemiological data on the phytoestrogen properties of the components of flaxseed Linum Usitatissimum L., especially lignans and products of their biotransformation in humans and animals enterodiol (END) and enterolactone (ENL) are presented. Flaxseed is
Cyclolinopeptides (CLs) are octa-, nona-, and decapeptides present in flaxseed (Linum usitatissimum L.) that may have immunosuppressive and antitumor activities, but little is known of their pharmacokinetics. Human serum albumin (HSA), the most abundant blood protein, is an important mediator of
Forsythia spp. are perennial woody plants which are one of the most extensively used medicinal sources of Chinese medicines and functional diets owing to their lignan contents. Lignans have received widespread attention as leading compounds in the development of antitumor drugs and healthy diets for
BACKGROUND
Suspension cultures of Linum album Kotschy ex Boiss. (Linaceae) accumulate podophyllotoxin (an anticancer agent) and could therefore serve as an alternative source of this important aryltetralin lactone lignan.
OBJECTIVE
The present work compared four podophyllotoxin extraction methods
Linum album has been shown to accumulate anti-tumor podophyllotoxin (PTOX) and its related lignans. In the present study, we examined the effects of five fungal extracts on the production of lignans in L. album cell cultures. Fusarium graminearum extract induced the highest increase of PTOX
Due to their pronounced cytotoxic activity, a number of aryltetralin lignans (ATLs), such as podophyllotoxin (PTOX), are used as antitumor compounds. The production of such molecules from entire plants or plant cell-tissue-organ cultures is thus of interest to the pharmaceutical industry. Hairy root
OBJECTIVE
In the present study two medicinal herbs Linum persicum and Euphorbia cheiradenia that are native to Iran were tested for their possible anticancer effect and induction of apoptosis on human tumor cell lines including leukemia cell lines.
METHODS
The effect of methanolic extracts of the
The present study describes the preliminary evaluation of the cytotoxic activity of a podophyllotoxin-like compound 4'-demethyl-6-methoxypodophyllotoxin (4'-DM-6-Mptox), isolated as one of the main lignans of Linum tauricum Willd. ssp. tauricum. The cytotoxic effects 4'-DM-6-Mptox were assessed by
