Synthesis of Quinone-Based N-Sulfonyl-1,2,3-triazoles: Chemical Reactivity of Rh(II) Azavinyl Carbenes and Antitumor Activity

Quinone-based N-sulfonyl-1,2,3-triazoles were synthesized by click chemistry and subsequently evaluated against eight types of cancer cell lines. Some of the compounds exhibited potent cytotoxicity with IC50 values < 1.0 mu M. Also, the cytotoxic potential of the quinones was evaluated against peripheral blood mononuclear (PBMC) and V79 cells. Additionally, the chemical reactivity of Rh(II) aza-vinyl carbenes generated in situ from these triazoles was studied. These compounds could provide promising new lead derivatives for more potent anticancer drug development.
