Autori: Ruihong Zhu, Yiyun Liu, Yongchao Ma, Tong Xu, Guanglei Yang, Antonio Zandona, Tena Čadež, Zrinka Kovarik, Heidi Qunhui Xie, Li Xu, Bin Zhao Sažetak radaEnvironmental contaminants, such as pesticides, can inhibit the enzymatic activity of acetylcholinesterase (AChE), an enzyme necessary for neurotransmission. The inhibitory effects of structurally diverse pesticides on AChE may result from either reversible or covalent interactions. Therefore, assessing their potency typically requires different assay design to determine either dissociation constants or rate constants, …

Autori: Ana-Marija Lulić, Lucija Marcelić, Alma Ramić, Andreja Radman Kastelic, Antonio Zandona, Nikola Maraković, Ines Primožič, Maja Katalinić Sažetak radaIn this study, we investigated the inhibitory activity of novel dodecylaminoquinuclidines (QAs) on neurotransmitter-hydrolyzing enzymes, specifically acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Following our previous findings, we modified the structure of a lead compound to develop more potent …
