s VII-XVIII, which were also tested for different types of actoprotective activities. Croton Condensation of 2-acetylfuran and 2-acetyl-5-methylfuran with aromatic aldehydes was used to prepare unsaturated ketones 1-(5-methylfuryl-2)-3-phenylpropenone-1 (I), 1-(5-methylfuryl-2)-3-(4'-methoxyphenyl)propenone-1 (II), and 1-(5-methylfuryl-2)-3-(3',4'-dimethoxyphenyl)propenone-1 (III) [8], which were reduced

A series of heterocyclic chalcone derivatives bearing heterocycles such as thiophene or furan ring as an isostere of benzene ring were carefully prepared, and the influence of heterocycles on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities was systematically investigated. Structure-activity relationships (SAR) analysis showed that the activities of thiophene ring-containing chalcones
