colchicum variegatum/neoplasms

Colchicine is a tubulin-binding natural product isolated from Colchicum autumnale. Here we report the in vitro anticancer activity of C-ring modified semi-synthetic derivative of colchicine; N-[(7S)-1,2,3-trimethoxy-9-oxo-10-(4-phenyl-piperidin-1-yl)-5,6,7,9 tetrahydrobenzo[a]heptalen-7-yl]acetamide

Colchicine, an antimitotic alkaloid isolated from Colchicum autumnale, is a classical drug for treatment of gout and familial Mediterranean fever. It causes antiproliferative effects through the inhibition of microtubule formation, which leads to mitotic arrest and cell death by apoptosis. Here, we

OBJECTIVE Colchicum pusillum belongs to the family Colchicaceae that particularly rich in tropolonic alkaloids. The aim of this study was to investigate the cytotoxicity and in vitro anticancer activity of Colchicum pusillum ethanolic extract on Colo-320 primer and Colo-741 metastatic colon

A new colchicinoid from Colchicum crocifolium Boiss. (Colchicaceae) was isolated and identified as N,N-dimethyl-N-deacetyl-(-)-cornigerine (5), along with four known compounds, but new to the species: (-)-colchicine (1), (-)-demecolcine (2), (-)-N-methyl-(-)-demecolcine (3) and

As a part of our continuing investigation of Jordanian Colchicum species, the biologically active components of Colchicum hierosolymitanum Feinbr and Colchicum tunicatum Feinbr (Colchicaceae) were pursued. The brine shrimp lethality test (BSLT) was used to direct the fractionation and isolation of

Chosen to reflect biodiversity in a phylogenetic sense, 100 fractionated plant extracts were screened in vitro for cytotoxicity following extraction and fractionation (polypeptide isolation). Of these 100 extracts, 30 were selected and then characterized preliminarily for antitumor potency and mode

Colchicine is the major alkaloid isolated from the plant Colchicum autumnale, which shows strong therapeutic effects towards different types of cancer. However, due to the toxicity of colchicine towards normal cells its application is limited. To address this issue we synthesized a series of seven

BACKGROUND The natural products have increasing important for the development of anticancer agents. Colchicum baytopiorum C.D. Brickell (C. baytopiorum), an endemic species for Turkey, contains colchicine and its derivatives. Stimulation of apoptotic and autophagy-mediated cell deaths are effective

OBJECTIVE Cancer is a long process that leads the organism to death and is associated with the normal cells acquiring the ability to divide permanently. Nowadays, the use of natural products in cancer therapy has a great importance. In addition, working with plants that are endemic to Turkey and

Colchicine, the main alkaloid of the poisonous plant meadow saffron (Colchicum autumnale L.), is a classical drug used for the treatment of gout and familial Mediterranean fever. Although colchicine is not clinically used to treat cancer because of toxicity, it exerts antiproliferative effects

The purpose of this review article is to outline plants currently used and those with high promise for the development of anti-gout products. All relevant literature databases were searched up to 25 March 2013. The search terms were 'gout', 'gouty arthritis', 'hyperuricemia', 'uric acid', 'xanthine

Colchicine is a tricyclic, lipid-soluble alkaloid derived from the plant of the Lily family Colchicum autumnale, sometimes called the "autumn crocus". It is predominantly metabolized in the gastrointestinal tract. Two proteins, P-glycoprotein (P-gp) and CYP3A4 seem to play a pivotal role, governing

Colchicine, the main alkaloid of Colchicum autumnale, is one of the most famous natural molecules. Although colchicine belongs to the oldest drugs (in use since 1500 BC), its pharmacological potential as a lead structure is not yet fully exploited. This review is devoted to the synthesis and
