Acetylcholinesterase and butyrylcholinesterase inhibitory activities of khellactone coumarin derivatives isolated from Peucedanum japonicum Thurnberg

A Novel Alternaria Species Isolated from Peucedanum japonicum in Korea

We isolated and examined a new Alternaria sp., which causes leaf spots on Peucedanum japonicum in Korea, by using molecular and morphological methods. Phylogenetic analysis based on a combined internal transcribed spacer region analysis and two protein-coding genes (gpd and Alt a1) demonstrated that the causal fungus was most closely related to A. cinerariae and A. sonchi, and relevant to A. br...

Evaluating the antioxidant and acetylcholinesterase inhibitory activities of some plants from Kohgiluyeh va Boyerahmad province, Iran

Background and objectives:Alzheimer’s disease (AD) is a neurodegenerative disorder. Nowadays, many investigations are performed to find new drugs for AD and medicinal plants are considered as one of the most important sources for developing new drugs. According to the role of oxidant agents and acetylcholinesterase enzyme (AChE) in AD, plants with antioxidant and AChE inhibitio...

design, synthesis, and acetylcholinesterase inhibitory activity of novel coumarin analogues

Design, synthesis, and acetylcholinesterase inhibitory activity of novel coumarin analogues.

Three series (series A-C) of coumarin analogues with phenylpiperazine functions as substitution were designed and synthesized for studying their potential for treating Alzheimer's (AD) disease. Their anticholinesterase activities were assayed according to Ellmann's method against freshly prepared acetylcholinesterase (AChE) from Electrophorus electricus using donepezil as the reference compound...

Cytotoxic properties of three isolated coumarin-hemiterpene ether derivatives from Artemisia armeniaca Lam

Considering multiple reports on cytotoxic activity of the Artemisia genus and its phytochemicals, in the current study A. armeniaca Lam. and the three components isolated from the plant were subjected to cytotoxic studies. Analytical fractionation of A. armeniaca aerial parts for the first time was directed to the isolation of 7-hydroxy-8-(4-hydroxy-3-methylbutoxy) comarin (armenin), 8-hydroxy-...
