Calcium-mimetic bone targeting

Calcium-mimetic bone targeting is a drug delivery strategy in which molecules or drug carriers are chemically engineered to mimic calcium’s strong affinity for bone mineral (hydroxyapatite). Typical agents include bisphosphonates, tetracyclines, and synthetic peptides or small molecules designed to localize drugs to bone tissue by binding to calcium-rich surfaces. While essential for improving bone-specific drug delivery in conditions like osteoporosis, bone metastasis, and bone regeneration, this is not a discrete molecular target such as a receptor, enzyme, or ion channel, but rather a targeting approach used in pharmaceutical formulation. Key safety concerns involve off-target binding and side effects associated with the bone-targeting agents themselves[2].
