The activity and gene expression of ornithine decarboxylase (ODC, an indicator of tumour promotion) were induced by the phorbol ester tumour promoter, 12-O-tetradecanoylphorbol-13-acetate (TPA), in mouse skin. In the present study, the effect of colchicine, a microtubule-disrupting agent, on ODC

OBJECTIVE

Colchicine, extracted from plants of the genus Colchicum, is a commonly prescribed drug for inflammatory diseases. It has been shown that colchicine affected various physiological responses in different models. However, the effect of colchicine on cytosolic free

The Re(I)-tricarbonyl synthon, [(188)Re(H(2)O)(3)(CO)(3)](+), was prepared by using carbon monoxide gas and amine-borane as the reducing agent. Colchicine, a naturally occurring cytotoxic alkaloid, was derivatized to iminodiacetic acid, the required array for the tridentate ligand system for

A major limitation in the treatment of cancer with natural product chemotherapeutic agents is the development of multidrug resistance (MDR). Multidrug resistance is attributed to enhanced expression of the multidrug resistance gene MDR1. Colchicine (CHC) is known to be one of the MDR drugs. We have

Successful treatment with anti-tumor necrosis factor (anti-TNF)-alpha of proteinuria in a patient with familial mediterranean fever (FMF) resistant to colchicine: anti-TNF drugs and FMF.

Familial mediterranean fever (FMF) is an autoinflammatory disease characterized by recurrent attacks of fever, peritonitis, pleuritis, and genetically by autosomal recessive inheritance. The major renal involvement in FMF is the occurrence of amyloidosis that can be prevented by a daily regimen of

Colchicine (COL) is a well-known and potent microtubule targeting anticancer agent. The purpose of our study was to identify conditions that increase sensitization of COL-resistant cancer cells that overexpress P-glycoprotein (P-gp). The anti-malarial drugs chloroquine (CHL), mefloquine (MEF) and

A novel microtubule depolymerizing colchicine analogue triggers apoptosis and autophagy in HCT-116 colon cancer cells.

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

BACKGROUND Colchicine, a tricyclic alkaloid, is commonly used in treatment due to its anti-inflammatory and anti-fibrotic effects. Beside its toxicity at high doses, colchicine is reported for its potential anticancer effects at lower concentrations. The present study aimed to evaluate the

NMK-BH2, a novel microtubule-depolymerising bis (indolyl)-hydrazide-hydrazone, induces apoptotic and autophagic cell death in cervical cancer cells by binding to tubulin at colchicine - site
