Propamidine（Cat No.:M071117）is an antimicrobial compound belonging to the diamidine class, known for its activity against protozoa and certain bacteria. It typically appears as a white crystalline powder and is often used in the form of propamidine isethionate. Propamidine is primarily employed in ophthalmic treatments, especially for eye infections like Acanthamoeba keratitis and conjunctivitis. It works by binding to microbial DNA, disrupting replication and cellular function. Due to its effectiveness and relatively low toxicity, it is used in topical applications such as eye drops and antiseptic formulations for external infections.
