background: acid phosphatase (acp) is suggested to be one of the virulence factors in leishmania and a correlation has been reported between leishmanial acid phosphatase (acp) activity and the severity of the disease in all types of leishmaniasis including zoonotic cutaneous leishmaniasis (zcl), which is a polymorphic disease.   objective : characterization of leishmania and its correlation wit...

The genus Sarcococca is widely distributed in South-East Asia and it comprises 14 species. The genus is traditionally used for gastrointestinal ulcers, infections, pain and in rheumatic fevers. Recently, our group has derived a comprehensive SAR relationship picture for a new series of natural cholinesterase inhibitors isolated from Sarcococca saligna (syn. S. pruniformis, Buxaceae). The fracti...

Non-steroidal anti-inflammatory drugs (NSAIDs) are the competitive inhibitors of cyclooxygenase (COX), the enzyme which mediates the bioconversion of arachidonic acid to inflammatory prostaglandins (PGs). Their use is associated with the side effects such as gastrointestinal and renal toxicity. The therapeutic anti-inflammatory action of NSAIDs is produced by the inhibition of COX-2, while the ...

acetylcholinesterase (ache) is the main enzyme for the breakdown of acetylcholine. nowadays, usage of the inhibitors of this enzyme is one of the most important types of treatment of mild to moderate neurodegenerative diseases such as alzheimer’s disease. herbal medicines can be a new source of inhibitors of this enzyme. in this study we examined around 100 different plants to evaluate their in...
