The Evaluation of the Potency of Newly Developed Oximes (K727, K733) and Trimedoxime to Counteract Acute Neurotoxic Effects of Tabun in Rats [PDF]
Aim: The ability of two newly developed oximes (K727, K733) to reduce tabun-induced acute neurotoxic signs and symptoms was evaluated and compared with currently available trimedoxime in rats.

Evaluation of Potency of Known Oximes (Pralidoxime, Trimedoxime, HI-6, Methoxime, Obidoxime) to in vitro Reactivate Acetylcholinesterase Inhibited by Pesticides (Chlorpyrifos and Methylchlorpyrifos and Nerve Agent (Russian VX) [PDF]
Nerve agents and pesticides belong to the group of organophosphates. They are able to inhibit irreversibly the enzyme acetylcholinesterase (AChE). Acetylcholinesterase reactivators were designed for the treatment of nerve agent intoxications.

Understanding the Interaction Modes and Reactivity of Trimedoxime toward MmAChE Inhibited by Nerve Agents: Theoretical and Experimental Aspects. [PDF]
Abstract The organophosphorus compounds (OP) are used as both chemical weapons and pesticides. However, these agents are very dangerous and toxic to humans, animals, and the environment. Thus, investigations with reactivators have been deeply developed in order to design new antidotes with better efficiency, as well as greater spectrum of ...

Acetylcholinesterase reactivators (HI-6, obidoxime, trimedoxime, K027, K075, K127, K203, K282): structural evaluation of human serum albumin binding and absorption kinetics. [PDF]
Acetylcholinesterase (AChE) reactivators (oximes) are compounds predominantly targeting the active site of the enzyme. Toxic effects of organophosphates nerve agents (OPNAs) are primarily related to their covalent binding to AChE and butyrylcholinesterase (BChE), critical detoxification enzymes in the blood and in the central nervous system (CNS ...

The reactivating and therapeutic efficacy of two combinations of oximes (HI‑6 + trimedoxime and HI‑6 + K203) was compared with the effectiveness of antidotal treatment involving single oxime (HI‑6, trimedoxime, K203) using in vivo methods.

Introduction. The new K-oximes, K-27 [1-(4-hydroxyimino-methylpyridinium)-4-(4-carbamoylpyridinium) propane dibromide] and K-48 [1-(4-hydroxyimino-methylpyridinium)-4-(4-carbamoylpyridinium) butane dibromide], show good in vitro efficacy in protecting acetylcholinesterase from inhibition by different organophosphorus compounds (OPCs), including nerve ...

ABSTRACTK027 [1‐(4‐hydroxyiminomethylpyridinium)‐3‐(4‐carbamoylpyridinium)–propane dibromide] is a promising new reactivator of organophosphate‐ or organophosphonate‐inhibited acetylcholinesterase (AChE) with low acute toxicity and broad spectrum efficacy. The aim of the present study was to compare the pharmacokinetics of both compounds.

Evaluation of the Potency of Two Novel Bispyridinium Oximes (
AbstractThe ability of two newly developed bispyridinium oximes (K456, K458) to reduce tabun‐induced acute neurotoxic signs and symptoms was compared with oxime K203 and trimedoxime using the functional observational battery. The neuroprotective effects of the oximes studied combined with atropine on rats poisoned with tabun at a sublethal dose (200 μg/
