Colchicine is a potent natural alkaloid that inhibits microtubule polymerization (IC50 = 3 nM) and acts as a competitive glycine receptor antagonist. It is widely used in research for its anti-inflammatory and immunosuppressive properties, applied in studies of gout, rheumatoid arthritis, Alzheimer's disease models, and NLRP3 inflammasome-related pathologies in both cellular and animal studies.
