ETHNOPHARMACOLOGICAL RELEVANCE: Rheumatoid arthritis (RA) is a diverse disease characterized by a variable, progressive course of articular and extra-articular symptoms that are linked with pain, disability, and mortality. The exact cause of rheumatoid arthritis is still being investigated, and there is no treatment for this debilitating, persistent, painful disease. Qurs-e-Mafasil, a herbal Unani preparation, is regarded as a potent treatment for Waja'al-Mafasil, a condition clinically similar to rheumatoid arthritis, but scientific evidence is scarce...

Colchicine, a natural compound extracted from Colchicum autumnale, is a phytotoxin, but interestingly, it also has multiple pharmacological activities. Clinically, colchicine is widely used for the treatment of gouty arthritis, familial Mediterranean fever, cardiovascular dysfunction and new coronary pneumonia. However, overdose intake of colchicine could cause lethal liver damage, which is a limitation of its application. Therefore, exploring the potential mechanism of colchicine-induced hepatotoxicity is meaningful...

The pharmacotherapeutic mechanism of colchicine, a tricyclic, lipid-soluble alkaloid extracted from the plant of the Lily family Colchicum autumnale, has not been fully understood in diverse disorders, including sepsis-induced acute lung injury (ALI). The study aimed at exploring the impact of colchicine on sepsis-induced ALI and the relevant mechanisms. Colchicine significantly attenuated ALI in mice caused by sepsis by alleviating respiratory dysfunction and pulmonary edema in mice, inhibiting NLRP3 inflammasome formation, and reducing oxidative stress, pyroptosis, and apoptosis of murine alveolar macrophage (J774A...

Many herbivorous insects not only cope with plant toxins but also sequester them as a defense against predators and parasitoids. Sequestration is a product of the evolutionary arms race between plants and herbivorous insects and has been hypothesized to incur physiological costs due to specific adaptations required. Contradictory evidence about these costs exists for insects sequestering only one class of toxin, but very little is known about the physiological implications for species sequestering structurally different classes of compounds...

Bioassay-guided isolation from Camellia sinensis (Theaceae) and Colchicum luteum (Liliaceae) utilizing an in vitro model of protease assay revealed colchicine ( 1 ) and caffeine (2) from chloroform fractions, respectively. Their structures were validated using spectral techniques. The purified compounds were further optimized with Gaussian software utilizing the B3LYP functional and 6-31G(d,p) basis set. The result files were utilized to determine several global reactivity characteristics to explain the diverse behavior of the compounds...

The objective of the present study was to determine the acute and subacute toxicity profile of a polyherbal formulation called "Goubion" in addition to the in vivo antihyperuricemic study using fructose-induced hyperuricemia. Goubion is a combination of Colchicum autumnale (tuber), Tribulus terresteris (fruit), Vitex negundo (leaves), Smilax chinensis (root), Glycyrrhiza glabra (root), and Curcuma amada (rhizome). The acute toxicity study revealed no signs of mortality and morbidity at a single dose of 2000 mg/kg...

Colchicine is a bioactive alkaloid originally from Colchicum autumnale and possesses excellent antiproliferative activity. However, colchicine-associated severe toxicity, gastrointestinal side effects in particular, limits its further therapeutic use. In the current study, we thus designed and synthesized a novel hybrid (CMH) by splicing colchicine and magnolol, a multifunctional polyphenol showing favorable gastrointestinal protection. The antitumor activity of CMH in Lewis lung carcinoma (LLC) was then evaluated in vitro and in vivo ...

OBJECTIVE: Breast cancer is one of the major causes of mortality among women. Due to many side effects of the existing chemotherapeutic agents, the research of anti-cancer drugs, including natural products, is still a big challenge. Here, we investigated the effects of colchicine on apoptosis of two breast cancer cell lines ( human MCF-7 and mouse 4T1). MATERIALS AND METHODS: In this experimental study, we evaluated the apoptotic effects of colchicine on (MCF-7) and (4T1), as well as a human cancer-associated fibroblast cell line as a control group...

In mid-April of 2018 light green to greenish yellow linear stripes (Fig. S1.) were observed on the foliage of meadow saffron (Colchicum autumnale) plants - which are native to Hungary - at a strictly protected Natura2000 site maintained by the Duna-Ipoly National Park (DNPI). By autumn, during the flowering season, flower breaking symptoms (Fig. S2.) were noticed, which indicated possible viral infection. With the permit of the Government Office of Pest County and the DNPI, 200 mg leaf sample was collected from one symptomatic plant in spring 2021 and stored at -70 °C until further processing...

An alkenal double-bond reductase enzyme (CaDBR1) was cloned from Colchicum autumnale L. The encoded enzyme catalysed 4-coumaraldehyde to 4-hydroxydihydrocinnamaldehyde (4-HDCA). Its functional characterization increased the understanding of colchicine biosynthesis. As a traditional medical plant, Colchicum autumnale L. is famous for producing colchicine, a widely used drug for alleviating gout attacks. The biosynthetic pathway of colchicine was revealed most recently, and 4-hydroxydihydrocinnamaldehyde (4-HDCA) has been verified as a crucial intermediate derived from L-phenylalanine...

Inflammation is a key feature of atherosclerosis. The inflammatory process is involved in all stages of disease progression, from the early formation of plaque to its instability and disruption, leading to clinical events. This strongly suggests that the use of anti-inflammatory agents might improve both atherosclerosis progression and cardiovascular outcomes. Colchicine, an alkaloid derived from the flower Colchicum autumnale , has been used for years in the treatment of inflammatory pathologies, including Gout, Mediterranean Fever, and Pericarditis...

In the literature, there is a scarcity of greener analytical approaches for colchicine (CLH) analysis. As a result, efforts were made in this study to develop and validate a greener reversed-phase high-performance thin-layer chromatography (HPTLC) technique for CLH analysis in traditional extracts (TE) and ultrasonication-based extracts (UBE) of commercial Unani formulations, commercial allopathic formulations, and Colchicum autumnale Pleniflorum (L.) obtained from Egypt and India. This new technique was compared to the regular normal-phase HPTLC method...

Cancer, one of the leading illnesses, accounts for about 10 million deaths worldwide. The treatment of cancer includes surgery, chemotherapy, radiation therapy, and drug therapy, along with others, which not only put a tremendous economic effect on patients but also develop drug resistance in patients with time. A significant number of cancer cases can be prevented/treated by implementing evidence-based preventive strategies. Plant-based drugs have evolved as promising preventive chemo options both in developing and developed nations...

The appearance of Meadow saffron (Colchicum autumnale), which contains colchicine, closely resembles Alpine leek (Allium victorialis), a popular edible wild vegetable in Northern Japan. This often results in the accidental ingestion of Meadow saffron and acute colchicine poisoning deaths. Here, we report on a case of acute colchicine poisoning death caused by the accidental ingestion of Meadow saffron. A man in his 70 s had been given wild vegetables from his neighborhood, which were then cooked and eaten by himself and his wife...

INTRODUCTION: Colchicine poisoning is a life-threatening intoxication. CASE REPORT: We report a case of food poisosing with Colchicum autumnale by confusion with wild garlic. The clinical presentation is the same as that of colchicine drug intoxication. The evolution can be fatal in case of massive ingestion. The proximity of the place of growth and their similar appearance in spring make Colchicum and wild garlic plants that can easily be confused. CONCLUSION: Physicians have to be vigilant in case of dysenteric syndrome and biological disturbances in spring and look for the consumption of perennial plant preceding symptoms...
