Synthesis and antimicrobial activity of Schiff bases derived from 2-chloro quinoline-3-carbaldehyde and its derivatives incorporating 7-methyl-2-propyl-3<i>H</i>-benzoimidazole-5-carboxylic acid hydrazide

<p>A series of Schiff bases consisting of two heterocyclic rings derived from 2-chloro quinoline-3-carbaldehyde and its derivatives incorporating 7-methyl-2-propyl-3<i>H</i>-benzoimidazole-5-carboxylic acid hydrazide have been accomplished and thoroughly characterized by various spectroscopic techniques including IR, MS, and multinuclear NMR. These compounds were screened for antimicrobial activity against <i>Escherichia coli, Staphylococcus aureus, Salmonella typhi</i>, and <i>Candida albicans.</i> The derivatives exhibited moderate activity against <i>E. coli</i> and <i>C. albicans</i>.</p>
