A novel series of benzoylsulfonamide derivatives were synthesized and biologically evaluated. Among them, 4-(biphenyl-4-ylmethylsulfanylmethyl)-N-(hexane-1-sulfonyl)benzamide (compound 18K) was identified as a proteintyrosinephosphatase 1B (PTP1B) inhibitor with potent and selective inhibitory activity against PTP1B (IC50=0.25 µM). Compound 18K functioned as a non-competitive inhibitor and bound

An improved methodology is reported for the synthesis of new series of mesotetrakis[aryl]‐21H,23H‐porphyrin derivatives 2a–h and was considered as a model to study their antioxidant and cytotoxic activities. The structures of the novel compounds were determined in 1H and 13C NMR, UV‐Vis, and elemental analyses. Among the derivatives, compounds 2c, 2d, and 2h showed strongest radical‐scavenging activity

derivative to detect cyanide ions in solution at micromolar concentrations. This structurally simplechemosensor displays a large decrease in emission intensity and a reversible color change from red to blue on contact with cyanide ions. Highly fluorescent polymeric films can be obtained by doping with the chemosensor. Such polymeric materials can be used for the sensing of the cyanide ions in polymer matrices

A new methodology for the synthesis of a new series of mesotetrakis[aryl]-21H,23H-porphyrin derivatives 5a–5d, 6a–6c, 7 and 8 is presented. Structures of new compounds were established based on both elemental and spectral data. Cytotoxicity activity of the newly synthesized compounds was investigated against two human cell lines MCF-7 and HepG2. Molecular docking was performed to investigate the binding
