investigated their inhibitory activities and mechanisms on tyrosinase by using Spectrofluorimetry, 1H and 13C NMR titration and IR spectra. The results of the fluorescence spectra and NMR titrations showed that the thiosemicarbazone moiety formed complexes with copper ions in the activecenter of the enzyme and played an important role in inhibiting the activities of the target compounds. The 5-functionalization
The invention provides compounds of formula la, lb and Ic: [Formula Ia, Ib, and Ic] and salts thereof, wherein variables are as described in the specification, as well as compositions comprising a compound of formula Ia-Ic, methods of making such compounds, and methods of using such compounds, e.g., as inhibitors of bacterial RNA polymerase and as antibacterial agents.
