Synthesis, anticancer evaluation, and electrochemical investigation of new chiral pyrazolo[4,3-e]tetrazolo[1,5-b][1,2,4]triazine sulfonamides

Synthesis of MM124 and MM125

Melting points were determined on a Mel-Temp apparatus and were uncorrected. ¹H and ¹³C nuclear magnetic resonance (NMR) spectra were recorded on a Varian spectrometer (400 MHz for ¹H and 100 MHz for ¹³C). The…
