Salicylaldehyde-indole-2-acylhydrazone: a simple, colorimetric and absorption ratiometric chemosensor for acetate ion
摘要:
A simple anion receptor (i.e. salicylaldehyde-indole-2-acylhydrazone) was synthesised and its recognition properties were investigated by naked-eye observation, UVvis titration spectra, 1H NMR spectroscopy and DFT calculations. The obtained results indicated that this receptor could realise the selective colorimetric sensing and absorption ratiometric response towards AcO in CH3CNDMSO medium, by virtue of threefold intermolecular hydrogen bonding interactions formed with phenolic OH, indole NH and amide NH.

A series of indole-2(3)-carboxylic acid hydrazones were synthesized and their antiproliferative activity was studied for the K562 leukemia, MCF7 breast adenocarcinoma, and HCT116 colon carcinoma cell lines and resistant HCT116p53KO subline in order to preliminary screen biological properties and to reveal the role of the aldehyde fragment and heterocycle in the ability of compounds to inhibit tumor
