title: Synthesis and in vitro anti-tumor activity of N-{1-[(3-thioxo-5,6-dihydroimidazo[2,1-c][1,2,4]thiadiazol-7-ylthio)thiocarbonyl]-2-imidazolidene}arylsulfonamides.
abstract: A series of N-{1-[(3-thioxo-5,6-dihydroimidazo[2,1-c][1,2,4]thiadiazol-7-ylthio)thiocarbonyl]-2-imidazolidene}arylsulfonamides (2a-z) was obtained by reacting 6,7-dihydro-1H-imidazo[2,1-c][1,2,4]thiadiazol-3-thione (1) with arylsulfonyl chlorides. The relationships between structure and anti-tumor activity revealed that compound 2o with p-Cl substituent at the phenyl ring was most active (-log GI50>8.00, -log TGI=7.66) and was found to exhibit high selectivity toward the leukemia CCRF-CEM cell line (Deltaf=3.08 and 3.31, respectively).
