(4,4′-dmb), potassium nitrate (KNO3), acetonitrile (MeCN),
potassium hexafluoro phosphate (KPF6), dichloromethane (DCM),
methanol (MeOH), and deuterated solvents (DMSO-d6and CD3CN) were purchased from Sigma-Aldrich and used without further
purification. Fetal bovine serum (FBS), RPMI 1640 (Corning Cellgro), and
Eagle’s Minimum Essential Medium (EMEM) (Corning Cellgro) were purchased
from VWR. Human malignant melanoma cells (SK-MEL-28) were obtained from the
American Type Culture Collection (ATCC). Prior to use, FBS was divided into 40
mL aliquots, heat inactivated (30 min, 55 °C), and then stored at
−20 °C. Deionized water of 18 MΩ cm resistivity from a
Barnstead filtration system was used for the biological experiments.
