Synthesis, X-ray structure analysis and computational studies of novel bis(thiocarbamoyl) disulfides with non-covalent S⋯N and S⋯S interactions
摘要:
In this Letter, we describe the synthesis of several bis(thiocarbamoyl) disulfides that present interesting intramolecular S center dot center dot center dot N and S center dot center dot center dot S interactions. In one case, crystals suitable for X-ray characterization have been obtained. The non-covalent interactions have been studied analyzing the crystal structure and by means of high level density functional theory (DFT) calculations (RI-PB86/TZVP) using both 'atoms-in-molecules' (AIM) and natural bond orbital (NBO) analyses.

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
摘要:
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 (Delta(f) = 3.08 and 3.31, respectively).
