In experiments using melanoma-bearing mice, NAcCAP and NPrCAP were found to be selectively incorporated into melanoma transplants and retained within melanoma cells, exerting a cytotoxic effect through oxidative stress that may derive from the tyrosinase-catalyzed production of cytotoxic free radicals from the tyrosine analogs (chemotherapeutic effect) [34]. Here, TYR is linked to melanoma.
