Hydroxystilbamidine
Hydroxystilbamidine is a cationic dye with antifungal, antitrypanosomal, antimalarial, and carcinostatic activities. Hydroxystilbamidine is able to bind to DNA and RNA in a non-intercalating manner, and is a powerful inhibitor of ribonucleases, thereby impeding cellular processes in protozoa. This agent was also shown to bind to and stablize trypanosomal lysosomes. Hydroxystilbamidine is commonly used as a diagnostic agent in neuroanatomy and as a histochemical stain.
