An iodinated doxorubicin analogue with antiamyloid activity. 4′-Iodo-4′-deoxydoxorubicin (IDOX) binds with high affinity to five types of natural amyloid fibrils including immunoglobulin light chains, amyloid A, transthyretin (methionine-30 variant), -protein (Alzheimer), and 2-microglobulin. This agent may inhibit fibril growth, increasing the solubility of amyloid tissue deposits and facilitating their clearance. IDOX has also been shown to insulin amyloid fibrillogenesis in vitro.
