The low efficiency of treatment strategies is one of the main obstacles to developing cancer inhibitors. Up to now, various classes of therapeutics have been developed to inhibit cancer progression. Peptides due to their small size and easy production co
an H-bond with the C = N as illustrated in FigureS1in the supplementary data Section24. In addition, the13C NMR spectrum exhibited a signal at 178.3 ppm, which was ascribed to the carbons of the two thioxo groups having overlapping. The mass of compound3was equivalent to the ...
