  Potential of aryl–urea–benzofuranylthiazoles hybrids as multitasking agents in Alzheimer's disease

  摘要：

  New benzofuranylthiazole derivatives containing the aryl urea moiety were synthesized and evaluated in vitro as dual acetylcholinesterase (AChE)-butyrylcholinesterase (BuChE) inhibitors. In addition, the cupric reducing antioxidant capacities (CUPRAC) and ABTS cation radical scavenging abilities of the synthesized compounds were assayed. The result showed that all the synthesized compounds exhibited inhibitory activity on both AChE and BuChE with 1-(4-(5-bromobenzofuran-2-yl)thiazol-2-yl)-3-(2fluorophenyl)urea (e25, IC50 value of 3.85 mu M) and 1-(4-iodophenyl)-3-(4-(5-nitrobenzofuran-2-yl) thiazol-2-yl)urea (e38, IC50 value of 2.03 mu M) as the strongest inhibitors against AChE and BuChE, respectively. Compound e38 was 8.5-fold more potent than galanthamine. The selectivity index of e25 and e38 was 2.40 and 0.37 against AChE and BuChE, respectively. Compound e2, e4 and ell (IC50 = 0.2, 0.5 and 1.13 mu M, respectively) showed a better ABTS cation radical scavenging ability than the standard quercetin (IC50 = 1.18 AM). Best poses of compounds e38 on BuChE and e25 on AChE indicate that the thiazole ring and the amidic moiety are important sites of interaction with both ChEs. In addition, the benzofuran ring and phenyl ring are anchored to the side chains of both enzymes by pi-pi(pi-pi) interactions. (C) 2015 Elsevier Masson SAS. All rights reserved.

  benzofuran moiety were prepared from the reaction of 2‐(2‐phenylhydrazono)‐1‐(5‐bromobenzofuran‐2‐yl)‐2‐chloroethanone with each of potassium thiocyanate, potassium selenocyanate, alkyl carbodithioate, and pyrmidine‐2‐thione derivatives. All the newly synthesized compounds were confirmed by elemental analysis, spectral data, and alternative route synthesis whenever possible.
