Published: May 2017

A series of novel benzo[d]oxazole derivatives (6a-n) have been synthesized and biologically evaluated as potential inhibitors of acetylcholinesterases (AChE) and butyrylcholinesterase (BChE). The chemical structures of all final compounds were confirmed by spectroscopic methods. In vitro studies showed that most of the synthesized compounds are potent acetylcholinesterase and butyrylcholinesterase inhibitors. Among them, compounds 6a and 6j strongly inhibited AChE and BChE activities with IC values of 1.03-1.35 and 6.6-8.1 μm, respectively. Docking studies also provided the binding modes of action and identified hydrophobic pi forces as the main interaction.

Background: Sporadic Alzheimer's disease (sAD) is the most prevalent type of dementia, characterized by progressive neurodegeneration. Intracerebroventricular (ICV) administration of streptozotocin (STZ) serves as a model for sAD, inducing neurodegeneration through oxidative stress, apoptotic damage, mitochondrial dysfunction, and neuroinflammation. Fenchone, a monoterpenoid, has been reported to possess neuroprotective properties by attenuating oxidative stress, acetylcholinesterase activity, mitochondrial dysfunction and neuroinflammation.

Background: Preeclampsia (PE) is marked by hypertension and detrimental sterile inflammatory response. Despite the reported anti-inflammatory effect of pyridostigmine bromide (PYR) in different models, its anti-inflammatory mechanism in PE is unclear. This study assessed whether such an anti-inflammatory effect involves inhibition of placental Toll-like receptor 4 (TLR4) signaling.

Background/aim: Alzheimer's disease is a complex, incurable to date, multifactorial disease, which suggests the need for continued development of pharmacotherapy.

Materials And Methods: A comprehensive literature search was conducted to identify known ligands with anticholinesterase activity, resulting in the discovery of over 100 alkaloids that are also available in the PubChem database. Subsequently, the ligands underwent molecular docking to evaluate their affinity for the target enzyme.

Galantamine plays a crucial role in the management of brain disorders. In this study, a series of galantamine analogues were designed, synthesized and evaluated as potential therapeutic agents for Alzheimer's disease (AD). Compound C2, a dual inhibitor of cholinesterase, was obtained by introducing a benzylpyridine ring to the hydroxyl group of galantamine.
