A number of N-(2-(1H-indol-3-yl)ethyl)-2-oxo-2H-chromene-3-carboxamides were synthesized and tested against AChE and BuChE. The in?vitro assessment of the synthesized compounds 4a-o revealed that most of them had significant activity toward AChE. The SAR study demonstrated that the introduction of benzyloxy moiety on the 7-position of coumarin scaffold can improve the anti-AChE activity. The best result was obtained with 7-(4-fluorobenzyl)oxy moiety in the case of compound 4o, displaying IC50value of 0.16?μM. Based on the docking study of AChE, the prototype compound 4o was laid across the active site and occupied both peripheral anionic site (PAS) and catalytic anionic site (CAS).

A novel class of selective anti-Helicobacter pylori agents, 2-oxo-2H-chromene-3-carboxamide derivatives, were prepared and evaluated for their anti-bacterial activity. All synthesized compounds showed little or no activity against different species of Gram-positive and Gram-negative bacteria and against various strains of pathogenic fungi. Some of them exhibited a potent and specific inhibitory effect on the growth of H. pylori, including metronidazole-resistant strains, in the 0.0039-16 μg/mL MIC range. A cytotoxic screening by the Trypan blue dye exclusion assay was also carried out on the most active compounds as anti-H. pylori agents. Among the derivatives examined for their cytotoxic potential, a number of them induced low cytotoxic effects.
