Biological Activity for Colchicine

Colchicine is a plant-derived alkaloid that binds to tubulin and depolymerizes microtubules. Identified as a candidate for repurposing for COVID-19. Inhibits NLRP3 inflammasomes. Also decreases TNF-α receptor expression and reduces cytokine levels in macrophages. Anti-inflammatory.
