Nowadays, deep eutectic solvents (DES) have become attractive since they can be formed by mixing different biologically non-harmful constituents. Although its components are considered safe, any newly formulated solvent must still …

Autori: Zrinka Kovarik, Dora Kolić, Tena Čadež, Goran Šinko, Petra Tuksar, Tamara Zorbaz, Christophe Curty, Nikolina Maček Hrvat Sažetak radaGiven the scarcity of experimental studies on A-series nerve agents (NAs), this paper provides ground-breaking insights and, for the first time, describes the inhibition and reactivation of human acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibited by these NAs using standard oximes. Furthermore, we present a detailed assessment of the toxicity profile of A-series …

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, …
