Leishmania microtubules play an important role not only in cell division, but also in keeping the shape of the parasite and motility of its free-living stages. Microtubules result from the self-assembly of alpha and beta tubulins, two phylogenetically conserved and very abundant eukaryotic proteins in kinetoplastids. The colchicine binding domain has inspired the discovery and development of several drugs currently in clinical use against parasites. However, this domain is less conserved in kinetoplastids and may be selectively targeted by new compounds...

A detailed NMR investigation of the chemical shifts of hydrogen and carbon atoms associated with the structure of the naturally occurring alkaloid colchicine was conducted using high field NMR. Initially, the experimental chemical shifts for colchicine in chloroform and DMSO were compared to the values calculated using density functional theory (DFT). There were significant deviations observed for the chloroform solvent, but these were only slight in the DMSO solution. Dilution of the chloroform solution changed the experimental chemical shifts and improved agreement with the DFT calculations, suggesting self-aggregation at higher concentrations...

The interstitial cell lineage of Hydra includes multipotent stem cells, and their derivatives: gland cells, nematocytes, germ cells, and nerve cells. The interstitial cells can be eliminated through two consecutive treatments with colchicine, a plant-derived toxin that kills dividing cells, thus erasing the potential for renewal of the differentiated cells that are derived from the interstitial stem cells. This allows for the generation of Hydra that lack nerve cells. A nerve-free polyp cannot open its mouth to feed, egest, or regulate osmotic pressure...

Colchicine is one of the oldest plant-based medicines used to treat gout and one of the most important alkaloid-based antimitotic drugs with anticancer potential, which is commercially extracted from Gloriosa superba. Clinical trials suggest that colchicine medication could prevent atrial fibrillation recurrence after cardiac surgery. In addition, therapeutic colchicine is undergoing clinical trials to treat non-diabetic metabolic syndrome and diabetic nephropathy. However, the industrial-scale biomanufacturing of colchicine have not yet been established...

Gout is a common disease responsible for recurrent flares triggered by the deposition of monosodium urate crystals secondary to longstanding hyperuricaemia. The management of gout implies both the treatment of flares and the treatment of hyperuricaemia itself. Recent improvement in the understanding of the disease led to the development of new drugs. Areas covered: This review covers data related to 'old' treatments of flares and hyperuricaemia, evidence on the recently approved drugs and emerging therapies in development...

Leukocytoclastic vasculitis (LCV) is a disease characterized by inflammation of small vessels presenting with petechiae and palpable purpura. Leukocytoclastic vasculitis often spontaneously resolves within weeks and requires only symptomatic treatment. Chronic or severe disease can require systemic treatment with agents such as colchicine, dapsone, or corticosteroids, which are effective but carry a risk for serious adverse events. These side effects and/or medical contraindications preclude some patients from taking systemic medications for LCV...

Capsular contracture is the most common complication of breast augmentation. Oxidized regenerated cellulose can be used as a matrix for drug transport. Colchicine is an antimitotic drug that interferes with various steps of wound healing. The aim of this study was to evaluate the effects of oxidized regenerated cellulose alone or in combination with colchicine on capsular contracture. Twenty-one adult female Wistar-Albino rats were divided into 3 groups. In group 1 silicone blocks only, in group 2 oxidized regenerated cellulose-wrapped silicone blocks, and in group 3 colchicine-impregnated oxidized regenerated cellulose-wrapped silicone blocks were inserted in the dorsal region...

CONTEXT: Some authors have proposed that post-mortem drug concentrations in bile are useful in estimating concentrations in blood. Both The International Association of Forensic Toxicologists (TIAFT) and the US Federal Aviation Administration recommend that samples of bile should be obtained in some circumstances. Furthermore, standard toxicological texts compare blood and bile concentrations, implying that concentrations in bile are of forensic value. AIM: To review the evidence on simultaneous measurements of blood and bile drug concentrations reported in the medical literature...

The European Society of Cardiology published in 2015 the new Guidelines on the management of pericardial diseases. Based on experts' opinions and recent clinical studies of respectable size, the new guidelines thoroughly revisit the criteria for hospitalization and precisely define severe cases. Another highlight regards medication. From now, first-line medical therapy should include the association of colchicine to the traditional non steroidal anti-inflammatory drugs or aspirin. The bi-therapy is recommended as soon as the first episode of pericarditis, for duration of 3 months...

BACKGROUND: Sweet's syndrome is characterized by fever, leukocytosis, and tender erythematous papules or nodules. It is a rare condition, particularly in the pediatric population, and has recently been proposed to be an autoinflammatory disease that occurs due to innate immune system dysfunction, involving several cytokines, which causes abnormally increased inflammation. To the best of our knowledge, no report has documented the cytokine profile in a pediatric patient with Sweet's syndrome...

Clinical evaluation of a colchicine specific antigen-binding fragment (Fab) in order to treat colchicine poisoning required the development of an accurate method allowing quantification of free and Fab-bound colchicine in plasma and urine, and free colchicine in tissues, to measure colchicine redistribution after Fab administration. Three methods have been developed for this purpose, and validated in plasma, urine and liver: total colchicine was determined after denaturation of Fab by dilution in water and heating; free colchicine was separated from Fab-bound colchicine by filtration with 30KDa micro-filters; tissues were homogenized in a tissue mixer...

Recurrent pericarditis is a common complication of acute pericarditis (15-30%) for which, in most cases, no underlying etiology is found [idiopathic recurrent pericarditis (IRP)]. IRP is currently viewed as an autoinflammatory disease with characteristic recurrent episodes of sterile inflammation. According to the most recent Guidelines, the initial treatment regimen consists of a combination of aspirin or non-steroidal anti-inflammatory drugs with colchicine followed by the addition of corticosteroids in resistant or intolerant cases...

Quinolin-6-yloxyacetamides (QAs) are a chemical class of tubulin polymerization inhibitors that were initially identified as fungicides. Here, we report that QAs are potent anti-proliferative agents against human cancer cells including ones that are drug-resistant. QAs act by disrupting the microtubule cytoskeleton and by causing severe mitotic defects. We further demonstrate that QAs inhibit tubulin polymerization in vitro. The high resolution crystal structure of the tubulin-QA complex revealed that QAs bind to the colchicine site on tubulin, which is targeted by microtubule-destabilizing agents such as colchicine and nocodazole...

A new series of 3-benzoylamino-5-(1H-imidazol-4-yl)methylaminobenzo[b]furans were synthesized and screened as antitumor agents. As a general trend, tested compounds showed concentration-dependent antiproliferative activity against HeLa and MCF-7 cancer cell lines, exhibiting GI50 values in the low micromolar range. In most cases, insertion of a methyl substituent on the imidazole moiety improved the antiproliferative activity. Therefore, methyl-imidazolyl-benzo[b]furans compounds were tested in cell cycle perturbation experiments, producing cell cycle arrest with proapoptotic effects...

Tophi (plural of tophus, Latin for "stone") are stone-like deposits of monosodium urate in the soft tissues, synovial tissues, or in bones near the joints. They are pathognomonic for gout, the most common inflammatory arthritis in the United States, with an estimated lifetime prevalence of 4%. It is usually the end result of loss of the balance between uric acid production and excretion. It can be found anywhere in the body especially in areas of friction or trauma. It is usually painless and rarely to present as the initial manifestation of gout...

Pericarditis is a debilitating condition that results from profound inflammation of the pericardial tissue. Between 10-15% of first episodes of acute pericarditis will be followed by several episodes refractory to conventional treatment. Current standard of care for pericarditis treatment includes high-dose non-steroidal anti-inflammatory drugs, colchicine and systemic corticosteroids, each associated with potentially severe toxicities and nominal efficacy. Interleukin-1 (IL-1), an apical pro-inflammatory cytokine, plays an important role as an autocrine magnifier of systemic inflammation in pericarditis...
