Simple synthesis of hydrazones with quorum quenching activity at room temperature in water
The hydrazone moiety is a major function in medicinal chemistry because of its wide range of pharmacological applications. Actual synthetic procedures usually involve harsh conditions, tedious workup and toxic solvents. Here, we report a simple procedure for the synthesis of hydrazones by condensation of phenyl/hydroxyl phenyl hydrazides with various substituted aldehydes using water as solvent. Products were obtained in 95–99% yields in less than 1 min at room temperature. The synthesized compounds were characterized by melting points, Fourier-transform infrared spectroscopy (FT-IR), proton nuclear magnetic resonance (1H-NMR) and carbon nuclear magnetic resonance (13C-NMR), and liquid chromatography–mass spectroscopy (LC–MS) and tested for their quorum quenching activity against Chromobacterium violaceum (C. Violaceum) CV026 as a bio-indicator strain.

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform.
