Synthesis, anti-cancer screening and tyrosyl-DNA phosphodiesterase 1 (Tdp1) inhibition activity of novel piperidinyl sulfamides.

Novel piperidinyl-based sulfamide derivatives were designed and synthesized through various synthetic routes. Anticancer activities of these sulfamides were evaluated by phenotypic screening on National Cancer Institute's 60 human tumor cell lines (NCI-60). Preliminary screening at 10μM concentration showed that piperidinyl sulfamide aminoester 26 (NSC 749204) was sensitive to most of the cell lines in the panel.
