In this paper, 21 naphthalene-chalcone derivatives were synthesized and their biologicaleffects were evaluated. The results showed that compounds 2a–2u displayed clear antidepressant activity at 30 mg/kg in the forced swimming test. Compounds 2h, 2o, 2t, and 2u exhibited a good antidepressant effect in the forced swimming test and tail suspension test at 30 mg/kg. Compounds 2h, 2o, 2t, and 2u but

2a and 2e by single crystal X-ray. Newly synthesized pyrazolines were investigated for their potential as antimicrobial agents. Compound 2a displayed promising antimicrobial activity against pathogenic Escherichia coli and Pseudomonas aeruginosa. Furthermore, the mechanism of the antimicrobial activity of 2a was demonstrated with the help of scanning electron microscopy (SEM), which revealed complete
A series of compounds which contain pyrazole, thiazole and naphthalene ring (1a-7a, 1b-7b, 1c-7c, 1d-7d) were firstly synthesized and their anti-proliferative activity, EGFR inhibitory activity, cytotoxicity and inhibition to Hela cell migration were evaluated. Compound 2-(3-(3,4-dimethylphenyl)-5-(naphthalen-2-yl)-4,5-dihydro-1H-pyrazol-1-yl) thiazol-4(5H)-one (7d) displayed the most potent inhibitory activity (IC50 = 0.86 mu M for Hela and IC50 = 0.12 mu M for EGFR). Structure-activity relationship (SAR) analysis showed that the anti-proliferative activity was affected by A-ring-substituent (-OCH3 > -CH3 > -H > -Br > -Cl > -F). Docking simulation of compound 7d into EGFR active site showed that naphthalene ring of 7d with LYS721 formed two p-pi bonds, which enhanced antitumor activity. Therefore, compound 7d may be developed as a potential antitumor agent. (C) 2014 Elsevier Ltd. All rights reserved.

A combination of tetrachlorosilane and zinc chloride in dichloromethane as an efficient and ambient binary reagent to promote a one-pot amidoalkylation reaction of enolizable ketones, aromatic aldehydes with acetonitriles, or benzonitrile have been developed. The newly synthesized beta-acetamidoketones 3 and beta-benzamidoketones 5 were obtained in good yields.
