linarin is a flavone glycoside in the plants flos chrysanthemi indici, buddleja officinalis, cirsium setosum, mentha arvensis and buddleja davidii, and has been reported to possess analgesic, antipyretic, anti-inflammatory and neuroprotective activities. in this paper, linarin was investigated for its ache inhibitory potential both in vitro and ex vivo. ellman’s colorimetric method was used for...

introduction: alzheimer’s disease (ad) is an age-related neurodegenerative disease, which impairs memory and cognitive function. walnuts are a dietary source of polyphenols, antioxidants and other compounds with health beneficial effects. these characteristic of walnuts make them perfect candidates for evaluation of their possible effects on neurodegenerative diseases. therefore the present stu...

Being a neurodegenerative disorder, Alzheimer's disease (AD) is the one of the most terrible diseases. And acetylcholinesterase (AChE) is considered as an important target for treating AD. Acetylcholinesterase inhibitors (AChEI) are considered to be one of the effective drugs for the treatment of AD. The aim of this study is to find a novel potential AChEI as a drug for the treatment of AD. In ...

Acetylcholinesterase (AChE), hydrolyzes acetylcholine to choline and acetate, thereby terminating this neurotransmitter effect at cholinergic synapses. Therefore, AChE inhibition is used for counterbalance the deficit in Alzheimer’s disease (AD) patients. In present work, order find new plant acetylcholinesterase inhibitors, hydroalcoholic extracts from seventeen medicinal species were screened...

We characterized 18 genes from Caenorhabditis elegans that, when mutated, confer recessive resistance to inhibitors of acetylcholinesterase. These include previously described genes as well as newly identified genes; they encode essential as well as nonessential functions. In the absence of acetylcholinesterase inhibitors, the different mutants display a wide range of behavioral deficits, from ...

The ability of antibiotics to inhibit acetylcholinesterase was measured in homogenates of goldfish brain. Puromycin aminonucleoside was the most potent inhibitor followed by puromycin, cycloheximide and acetoxycycloheximide. Puromycin effectively impaired retention of active-avoidance learning in goldfish when injected either immediately before or after training, while puromycin aminonucleoside...

The aim of this review is to describe side effects of five antidementives which are approved by the United States Food and Drug Administration (FDA); four acetylcholinesterase inhibitors and one glutamate - or N-metyl-D-aspartat receptor antagonist - memantine. The antidementives are well tolerated and undesired effects are rare; except hepatotoxicity of tacrine and gastrointestinal side effect...

This study investigates the alteration of serum cholinesterase levels in diabetics and its possible relationship to blood glucose, insulin, triglyceride, and cholesterol levels. Fourteen phasic insulin-dependent diabetes mellitus patients were compared with 10 insulin-dependent diabetes mellitus, 10 noninsulin-dependent diabetes mellitus, and 10 normal controls. Each group was matched for age, ...

Acetylcholinesterase is a key enzyme in cholinergic neurotransmission for hydrolyzing acetylcholine and has been shown to possess arylacylamidase activity in addition to esterase activity. The enzyme is found at various loci, where its functional significance remains to be clarified, and it exists in multiple molecular forms. Sheep platelets have been shown to exhibit acetylcholinesterase activ...
