Abstract
Ligand-drug conjugates for targeted melanoma therapies are disclosed herein. A ligand is conjugated to a cytotoxic cancer drug through a cleavage linker. The ligand can bind to an overexpressed receptor on a cancer cell, resulting in selectivity. This allows the drug to enter a cancer cell selectively and release the drug within that specific cancer cell. Such therapies provide selectivity to melanoma through a ligand that targets the MC1R receptor, which is highly expressed in 80% of malignant melanomas. The ligand-drug conjugates can be used to deliver a wide range of cytotoxic cancer drugs selective to melanoma cells which may solve the drug resistance problem of melanoma in current therapies.
