CCZ01048

CCZ01048, an analogue of α-melanocyte-stimulating hormone (α-MSH), demonstrates a high binding affinity for the melanocortin 1 receptor (MC1R), with a Ki of 0.31 nM. It rapidly internalizes into B16F10 melanoma cells and exhibits notable in vivo stability, making it a promising candidate for PET imaging of malignant melanoma [1].
