Abstract A series of novel, azasugar-modified 2-monosubstituted, 2,6- and 2,7-bissubstituted anthraquinone derivatives have been synthesized by the nucleophilic substitution of N -alkylamino azasugar with mono-, bis(2-chloroacetamido)anthraquinones. Their cytotoxic activities against HeLa and MCF-7 cells were preliminarily evaluated and compound 9a with mono-azasugar pendant at 2-position showed similar
Abstract The synthesis and characterization of a new cationic anthraquinone derivative (S3) soluble in water has been described. Its absorption characteristics in aqueous and N,N-dimethylformamide solutions have been determined. Аntimicrobial activity of the compound S3 was tested in vitro towards eight pathogenic bacteria and two yeasts strains. The results obtained suggest that the newly synthesized
difficult to induce arbitrary photochemical reactions on specific molecules because of their poor molecular selectivity. Here we report a selective and nontoxic photochemical reaction system utilizing photoactivated mesoporous silica nanoparticles to control biological functions.

of 0.34-149.10 µM. The inhibition percentage of VEGFR-2 was measured for all the compounds and found to be in the range of 90.09-20.44%. The promising compounds 8, 12, 13, 16 and 17 were selected to measure their possible multikinase inhibitory activity against VEGFR-2 and EGFR. IC50 of the promising compounds were in the range of 247-793 nM for VEGFR-2 in reference to sunitinib (IC50 320 nM), and 369-725 nM
