This is the hydropathic complementary peptide designed to bind and neutralize the activities of beta Amyloid (1-42), beta Amyloid (16-20) and beta Amyloid (25-35) - peptides known to be the most important for self aggregation and cytotoxicity. This peptide is a candidate for the development of drugs to prevent neurotoxicity and deposition of amyloid beta in the brains of the Alzheimer’s disease patients.
