An inhibitive assay of insecticides using Acetylcholinesterase (AChE) from the local fish Clarias batrachus is reported. AChE was assayed according to the modified method of Ellman. Screening of insecticide and heavy metals showed that carbofuran and carbaryl strongly inhibited C. batrachus AChE. The inhibition concentration (IC) IC50 values (and the 95% confidence interval) for both carbofuran...

Acetylcholinesterase enzyme (AChE) is the that catalyzes hydrolysis of neurotransmitter acetylcholine to choline. Inhibitors this (AChE-i) are used treat Alzheimer's, a neurodegenerative disease. Due side effects drugs used, there has been an increased interest in investigating inhibitory potentials natural products which presumed have fewer effects. For purpose, highland honey, chestnut royal ...

"Rheumatoid disease" in its acute or chronic form with systemic or local manifestations may simulate many diseases in general medicine. Local manifestations may resemble many specific arthritides and bony and muscular lesions with secondary joint involvement (Ellman, 1947; Ellman and Ball, 1948), and two cases of a chondro-osseous dystrophy, which had been regarded as an arthritic manifestation...

Objective(s): Alzheimer’s disease (AD) as progressive cognitive decline and the most common form of dementia is due to degeneration of the cholinergic neurons in the brain. Therefore, administration of the acetylcholinesterase (AChE) inhibitors such as donepezil is the first choice for treatment of the AD. In the present study, we focused on the synthesis and anti-cholinesterase evaluation of n...
