In line with this modern paradigm, a series of 8‐imino‐2‐oxo‐2H,8H‐pyrano[2,3‐f]chromene analogs (4a–q) were synthesized and evaluated for their multitarget‐directed activity on acetylcholinesterase, butyrylcholinesterase (BuChE), 2,2’‐azino‐bis(3‐ethylbenzthiazoline‐6‐sulfonic acid) (ABTS) radical, and amyloid‐β peptide (Aβ) specific targets for Alzheimer's

  A series of fused tricyclic coumarin derivatives bearing iminopyran ring connected to various amido moieties were developed as potential multifunctional anti-Alzheimer agents for their cholinesterase inhibitory and radical scavenging activities. In vitro studies revealed that most of these compounds exhibited high inhibitory activity on acetylcholinesterase (AChE), with IC50 values ranging from 0.003 to 0.357 mu M which is 2-220 folds more potent than the positive control, galantamine. Their inhibition selectivity against AChE over butyrylcholinesterase (BuChE) has increased about 194 fold compared with galantamine. The developed compounds also showed potent ABTS radical scavenging activity (IC50 7.98 -15.99 mu M). Specifically, the most potent AChE inhibitor 6n (IC50 0.003 +/- 0.0007 mu M) has an excellent antioxidant profile as determined by the ABTS method (IC50 7.98 0.77 mu M). Moreover, cell viability studies in SK N SH cells showed that the compounds 6m-q have significant neuroprotective effects against H2O2-induced cell death, and are not neurotoxic at all concentrations except 6n and 6q. The kinetic analysis of compound 6n proved that it is a mixed-type inhibitor for EeAChE (K-i1 0.0103 mu M and K-i2 0.0193 mu M). Accordingly, the molecular modeling study demonstrated that 6m-q with substituted benzyl amido moiety possessed an optimal docking pose with interactions at catalytic active site (CAS) and peripheral anionic site (PAS) of AChE simultaneously and thereby they might prevent aggregation of A beta induced by AChE. Furthermore, in silico ADMET prediction studies indicated that these compounds satisfied all the characteristics of CNS acting drugs. Most active inhibitor 6n is permeable to BBB as determined in the in vivo brain AChE activity. To sum up, the multipotent therapuetic profile of these novel tricyclic coumarins makes them promising leads for developing anti-Alzheimer agents. (C) 2015 Elsevier Masson SAS. All rights reserved.

  In line with the modern multi-target-directed ligand paradigm of Alzheimer's disease (AD), a series of 19 compounds composed of flavone and cyanoacetamide groups have been synthesized and evaluated as multifunctional agents against AD. Biological evaluation demonstrated that compounds 7j, 7n, 7o, 7r, and 7s exhibited excellent inhibitory potency (ACNE, IC50 of 0.27 +/- 10.012 to 1.006 +/- 0.075 mu M) and good selectivity toward acetylcholinesterase, significant antioxidant activity, good modulation effects on self-induced A beta aggregation, low cytotoxicity, and neuroprotection in Havone-cyanoacetamide human neuroblastoma SK-N-SH cells. Further, an inclusive study on the interaction of 7j, 7n, 70, 7r, and 7s with AChE at physiological pH 7.2 using fluorescence, circular dichroism, and molecular docking methods suggested that these derivatives bind strongly to the peripheral anionic site of AChE mostly through hydrophobic interactions. Overall, the multifunctional profiles and strong AChE binding affinity highlight these compounds as promising prototypes for further pursuit of innovative multifunctional drugs for AD.
