Neomycin A sulfate, EvoPure® also known as neamine, is a highly purified neomycin compound found in standard grade neomycin. Neomycin A has been found to have the lowest antibacterial activity; about 10% of the activity of neomycin B. Interestingly, recent research has found neomycin A to inhibit angiogenin translocation in tumor cell nuclei effectively inhibiting tumor growth. Neomycin A (neamine) has a lower toxicity profile than other neomycin components making it a favorable drug for cancer research.
