Eight Novel chalcones were synthesized and their structures were confirmed by different spectral tools. All the prepared compounds were subjected to SRB cytotoxic screening against several cancer cell lines. Compound 5c exerted the most promising effect against MCF7 and HEP2 cells with IC 50 values of 9.5 and 12 µg/mL, respectively. Real-time PCR demonstrated the inhibitory effect of compound 5c on the expression level of Anti...

Alzheimer’s disease (AD) is a multifactorial incurable neurodegenerative disorder. To date, cholinesterase inhibitors (ChEI) are the mainstay line of treatment to ameliorate the symptoms of AD. Tacrine and donepezil are considered two important cornerstones of anti-dementia drugs. Accordingly, novel series of hexahydrobenzothienocyclopentapyridines, octahydrobenzo-thienoquinolines, hexahydrocyclopenta(thienoquinoline/thienodip...

Fifteen new benzothiophene-based compounds were designed, synthesized, and evaluated as potential anti-Alzheimer agents. Most of the synthesized compounds exhibited remarkable AChE inhibitory activity and effectively inhibited self-mediated β-amyloid protein in vitro. Compound 3g (IC 50 = 72.488 ± 3.69 μM) showed a significant β-amyloid inhibitory effect exceeding that of donepezil (IC 50 = 87.414 ± 4.46 μM). Furthermore, comp...
