Tubulin is the target for many small-molecule natural compounds, which alter microtubules dynamics, and lead to cell cycle arrest and apoptosis. One of these compounds is colchicine, a plant alkaloid produced by Colchicum autumnale. While C. autumnale produces a potent cytotoxin, colchicine, and expresses its target protein, it is immune to colchicine's cytotoxic action and the mechanism of this resistance is hitherto unknown. In the present paper, the molecular mechanisms responsible for colchicine resistance in C...

A 58-year-old patient presented with a severe, episodic panniculitis of the upper legs. Necrosis of the fatty tissue and a suspected superinfection led to amputation of one leg. The panniculitis was caused by a hereditary deficiency of alpha-1 antitrypsin (AAT) due to a ZZ mutation of the AAT gene. Neutrophilic panniculitis is found in 0.1% of patients with the ZZ mutation and therefore is the rarest clinical manifestation of AAT deficiency. With the exception of mild COPD, the patient had no other typical clinical symptoms of AAT deficiency...

PURPOSE: 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 determining the biological activities of these plant extracts, is extremely important due to the potential for new drug development. There is no comparative study available in the literature on the antitumor effects of Colchicum sanguicolle, a new found species of the genus Colchicum in Turkey, Crateagus microphylla, of the genus Crateagus and Centaurea antiochia of the genus Centaurea...

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 through the inhibition of microtubule formation by blocking the cell cycle at the G2/M phase and triggering apoptosis. Colchicine can still be used as a lead compound for the generation of potential anticancer drugs. Thus, numerous analogues of colchicine have been synthesized in the hope of developing novel, useful drugs with more favourable pharmacological profiles...

BACKGROUND: According to traditional Persian medicine (TPM) resources, the human digestive system includes four steps. In the first step, gastric digestion, the ingested food pours into the stomach and changes into the leachate called chylous due to the heat produced in the stomach. In the second step, hepatic digestion, the chylous enters in the liver through mesenteric vessels and transforms into the quadruple humors, sanguine, phlegm, bile and black bile due to the liver heat. In the case of humor predominance, using moshel or cathartic medicines is considered as a strategic medical plan...

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 report that a novel colchicine analog, 4o (N-[(7S)-1,2,3-trimethoxy-9-oxo-10-[3-(trifluoromethyl)-4-chlorophenylamino]-5,6,7,9-tetrahydrobenzo[a]heptalen-7-yl]acetamide), which exhibited potent anticancer activities both in vitro and in vivo...

Colchicine, extracted from the colchicum autumnale plant, used by the ancient Greeks more than 20 centuries ago, is one of the most ancient drugs still prescribed even today. The major mechanism of action is binding to microtubules thereby interfering with mitosis and subsequent modulation of polymorphonuclear leukocyte function. Colchicine has long been of interest in the treatment of cardiovascular disease; however, its efficacy and safety profile for specific conditions have been variably established in the literature...

Colchicine is derived from Colchicum autumnale and Gloriosa superba and is used to treat acute gout and familial Mediterranean fever (FMF). Musculoskeletal adverse effects range from myopathy to rhabdomyolysis. An 18-year-old woman, with a 2-year history of FMF treated with colchicine, took 9 colchicine pills (4.5 mg) to relieve severe abdominal pain. On the sixth day of hospitalization, the patient's condition worsened, and she died. As this was a case of fatal poisoning, a forensic autopsy was performed, and the cause of death was determined to be complications of muscle destruction due to colchicine intoxication with the findings of myocytolysis, positive antimyoglobin antibody staining kidney tubules...

Colchicine poisonings are serious and highly fatal conditions that occur as a result of food poisoning from plants that contain this alkaloid or overdose with drug containing colchicine. The leaves of edible wild garlic because of their similarity are often replaced with highly poisonous leaves of autumn crocus, causing poisoning. Described are two cases of food poisoning with Colchicum autumnale, who had similar symptoms in the initial stage, but different clinical course and outcome. Signs of poisoning require early identification and intensive supportive therapy, which increases the chances of survival...
