Characterization of Amide Bond Conformers for a Novel Heterocyclic Template of N-acylhydrazone Derivatives

Molecules, 2013
Herein we describe NMR experiments and structural modifications of 4-methyl-2-phenylpyrimidine-N-acylhydrazone compounds (aryl-NAH) in order to discover if duplication of some signals in their 1H- and 13C-NMR spectra was related to a mixture of imine ...

Synthesis and antiproliferative evaluation of new hybrids of piperine and acylhydrazone

Natural Product Research
Piperine, a natural amide isolated from the genus of Piper, serves as a pharmacophore in medicinal chemistry. In this study, we synthesised and evaluated 18 novel piperine-acylhydrazone hybrids (4a–4r) for their antiproliferative activities in vitro. The structures of these hybrids were validated using 1H,13C NMR, and HR-ESI-MS data.
