2-(Phenylsulfonyl)quinoline N -hydroxyacrylamides as potent anticancer agents inhibiting histone deacetylase
摘要:
This study reports the design and synthesis of 2-(phenylsulfonyl)quinoline N-hydroxyacrylamides (8a-k). Structure-activity relationship studies focusing on regio-effect of N-hydroxyacrylamide moiety and influence of the sulfonyl linker revealed that N-hydroxy-3-[3-(quinoline-2-sulfonyl)-phenyl]-acrylamide (8f) showed remarkable enzymatic and cellular activity. The GI(50) values of 8f for HL-60, HCT116, PC-3, and A549 cells were found to be 0.29, 0.08, 0.15, and 0.27 mu M, respectively. The compounds are therefore more potent than FDA approved PXD-101 and SAHA. They also have an effect on the acetylation degree of histone H3 and alpha-tubulin. In in vivo studies, 8f showed marked inhibition of the growth of HCT116 xenografts. (C) 2016 Published by Elsevier Masson SAS.

2-phenylthiopyridines using BBr3 as the boron source under metal-free conditions has been reported. The reaction exhibited site exclusivity, and the synthesized aryl boronates were freely converted to various useful intermediates. Thus, this facile method would be beneficial to synthesize structurally diversified phenylthioethers derivatives and other materials containing boron-nitrogen coordination.
Manganese(II), Nickel(II), and Palladium(II) Complexes of a Terpyridine-Like Ligand Containing a Sulfur Linkage, and an Analogous NCN Pincer Palladium(II) Complex: Synthesis, Characterization, and Pd-Catalyzed Reactions
Coordination properties of new polypyridines containing a single sulfur linkage, 6-(2′′-pyridylthio)-2,2′-bipyridine (L1) and 1-(2′-pyridyl)-3-(2′′-pyridylthio)benzene (HL2), are described. The man...
