The article conveys some information:
Herein, the synthesis of a new series of thymol-based ethers I [R = Me, H2C:CH, CN, EtO2C, Ph, 2-BrC6H4, etc.] and their microbiol. screening against eight strains of H. pylori and the cytotoxic activity against human gastric adenocarcinoma (AGS) cells are reported. Structural anal. comprehended elemental anal. and 1H/13C/19F NMR spectra. The anal. of structure-activity relationships within this mol. library of these structurally-related compounds showed that some chem. modifications of the OH group of thymol led to broad-spectrum growth inhibition on all isolates. Preferred substitutions were benzyl groups compared to alkyl chains and the specific presence of functional groups at para position of the benzyl moiety such as 4-CN and 4-Ph endowed the most anti-H. pylori activity toward all the strains with min. inhibitory concentration (MIC) values up to 4μg/mL. Poly-substitution on the benzyl ring was not essential. Moreover, several compounds characterized by the lowest min. inhibitory concentration/min. bactericidal concentration (MIC/MBC) values against H. pylori were also tested in order to verify a cytotoxic effect against AGS cells with respect to 5-fluorouracil and carvacrol. In the experiment, the researchers used many compounds, for example, 4-Cyanobenzyl bromide(cas: 17201-43-3Electric Literature of C8H6BrN)
4-Cyanobenzyl bromide(cas: 17201-43-3) can reacts with 2H-tetrazole in the presence of KOH to yield 4-[(2H-tetra-zol-2-yl)methyl]benzonitrile. And it may be used in the synthesis of ligands containing a chelating pyrazolyl-pyridine group with a pendant aromatic nitrile.Electric Literature of C8H6BrN
