Organophosphate (OPs) compounds are widely used in intensive agriculture to improve production, protect crops and control diseases vectors. The main mechanism of toxicity of OPs is the inhibition of the Cholinesterase enzymes. In this study the acetylcholinestrase (AChE), butyrylcholinesterase (BChE) and specific acetylcholinestrase (SAChE) activities as potential biomarkers of exposure to OPs ...

To Pasteur’s famous dictum, ‘‘Chance favors the prepared mind,’’ could arguably be added the corollary, ‘‘As the number of chances increases, so increases the effect of favor.’’ It is nearly a truism that a great many important discoveries in chemistry originated not from careful design, but from astute observations of unintended experiments. Suppose, then, that creativity were applied to the t...

This study was undertaken to evaluate anticholinesterase activity of some benzimidazole derivatives due to their biological importance. Previously synthesized 14 benzimidazole compounds were used in biological studies. Inhibitory activities of related compounds on Acetylcholine esterase (AChE, E.C.3.1.1.7 from Electric Eel) enzyme have been determined by a modified Ellman’s colorimetric method....

Since the discovery of cortisone, the gold treatment of rheumatoid arthritis has been overshadowed by the dramatic action of this new remedy. As both cortisone and ACTH have been shown to be capable of maintaining their effect in a proportion of cases with appropriate maintenance dosage, and particularly as cortisone can be given by mouth, it would appear at first sight that there can no longer...

Leutea avicenniae Mozaff. belongs to Apiaceae family is an endemic species distributed in the west of Iran. The aim of this study was to investigate the antioxidant activity and acetylcholinestrase (AchE) inhibition of the crude extract, fractions and isolated compounds from methanolic fraction of L. avicenniae. Five compounds were detected from methanol fraction, three phenolic compounds as p-...
