Abstract
The A-series is the most recent generation of chemical warfare nerve agents (CWA) which act directly on the inhibition of the human acetylcholinesterase (HssAChE) enzyme. These compounds lack accurate experimental data on their physicochemical properties, and there is no evidence that traditional antidotes effectively reactivate HssAChE inhibited by them. In the search for potential antidotes, we employed virtual screening, molecular docking, and molecular dynamics (MD) simulations for the theoretical assessment of the performance of a library of Mannich phenols as potential reactivators of HssAChE inhibited by the Novichok agents A-230, A-232, and A-234, in comparison with the commercial oximes pralidoxime (2-PAM), asoxime (HI-6), trimedoxime (TMB-4), and obidoxime. Following the near-attack conformation (NAC) approach, our results suggest that the compounds assessed would face difficulties in triggering the proposed nucleophilic in-line displacement mechanism. Despite this, it was observed that certain Mannich phenols presented similar or superior results to those obtained by reference oximes against A-232 and A-234 model, suggesting that these compounds can adopt more favourable conformations. Additional binding energy calculations confirmed the stability of the model/ligands complexes and the reactivating potential observed in the molecular docking and MD studies. Our findings indicate that the Mannich phenols could be alternative antidotes and that their efficacy should be evaluated experimentally against the A-series CWA.

FRONTIERS IN TOXICOLOGY 2023; 4:1004705.

Abstract
Background: The whole world has learned about the existence of a highly toxic neuro-paralytic substance called Novichok. A wide range of neuro-paralytic toxins were used during the wars of decades ago, which also had harmful and irreversible effects. Fortunately, the establishment of conventions prohibiting the use of these weapons prevented the adverse clinical consequences of these compounds. What we did in the present study was to evaluate the clinical features of Novichok, how to manage exposure to it, and to evaluate the prognostic aspects associated with this poisoning agent. Methods: The manuscript especial databases including Medline, Web of knowledge, Google scholar, and Scopus were deeply searched by the two blinded investigators for all eligible studies based on the considered keywords. Initially 98 articles were initially collected by database searching that considering eligibility criteria, 83 articles were finally eligible for the final assessment. There is a lack of clinical trials and case-cohort studies on general population about treatment and side effects when it comes to human nerve agents and most of the data in our search is based on animal studies. Results: In evaluating various clinical, auto physiological and prognostic aspects of exposure to these substances, special attention was necessary to the following points. First, Novichok agents are considered more potent than other toxic agents. Pathophysiologically, these agents irreversibly bind acetylcholinesterase and produce a rapid cholinergic toxidrome which is responsible for the clinical manifestations as well as the potential dangerous and life threatening side effects caused by these agents. Uniquely, these agents are thought to also target every neuron in the central and peripheral nervous system. As a managerial and therapeutic approach, early and timely treatment of its related complication along with prevents massive exposure and decontamination in addition to rapid resuscitation can prohibit debilitating neuropathy and death due to facing it. Conclusion: The present review highlights the importance of recognizing the potential acute toxic effects of Novichok agents, diagnostic and therapeutic approaches (life-saving antidotal therapy) to complications and ultimately the application of guidelines to improve the prognosis of exposure to these agents for both victims and medical community.

Abstract
Reactivation of inhibited acetylcholinesterase remains an important therapeutic strategy for the treatment of poisoning by organophosphorus compounds, such as nerve agents or pesticides. Although drugs like obidoxime or pralidoxime have been used with considerable success, there is a need for new substances capable of reactivating acetylcholinesterase with a broader scope and increased efficacy. Possible screening candidates must fulfill two fundamental requirements: They must (i) show an affinity to acetylcholinesterase well balanced between sufficient binding and competitive inhibition and (ii) facilitate the nucleophilic cleavage of the phosphorylated catalytic serine residue. We attached a variety of nonaromatic primary and secondary amines to a coumarin core through selected alkoxy side linkers attached at coumarin positions 6 or 7 to obtain a small set of possible reactivators. Evaluation of their inhibition and reactivation potential in vitro showed some activity with respect to acetylcholinesterase inhibited by cyclosarin.

Abstract
A family of novel efficient non-oxime compounds exhibited promising reactivation efficacy for VX and sarin inhibited human acetylcholinesterase was discovered. It was found that aromatic groups coupled to Mannich phenols and the introduction of imidazole to the ortho position of phenols would dramatically enhance reactivation efficiency. Moreover, the in vivo experiment was conducted, and the results demonstrated that Mannich phenol L10R1 (30 mg/kg, ip) could afford 100% 48 h survival for mice of 2*LD50 sarin exposure, which is promising for the development of non-oxime reactivators with central efficiency.

Abstract
In an effort to develop new therapeutic agents to treat Alzheimer's disease, a series of donepezil-based analogs were designed, synthesized using an environmentally friendly route, and biologically evaluated for their inhibitory activity against electric eel acetylcholinesterase (AChE) enzyme. In vitro studies revealed that the phenyl moiety of donepezil can be successfully replaced with a pyridine ring leading to equally potent inhibitors of electric eel AChE. Further kinetic evaluations of the most potent inhibitor showed a dual-binding (mixed inhibition) mode, similar to donepezil. Molecular modeling studies suggest that several additional residues could be involved in the binding of this inhibitor in the human AChE enzyme active site compared to donepezil.

Abstract
Since several decades oximes have been used as part of treatment of nerve agent intoxication with the aim to restore the biological function of the enzyme acetylcholinesterase after its covalent inhibition by organophosphorus compounds such as pesticides and nerve agents. Recent findings have illustrated that, besides oximes, certain Mannich phenols can reactivate the inhibited enzyme very effectively, and may therefore represent an attractive complementary class of reactivators. In this paper we further probe the effect of structural variation on the in vitro efficacy of Mannich phenol based reactivators. Thus, we present the synthesis of 14 compounds that are close variants of the previously reported 4-amino-2-(1-pyrrolidinylmethyl)-phenol, a very effective non-oxime reactivator, and 3 dimeric Mannich phenols. All compounds were assessed for their ability to reactivate human acetylcholinesterase inhibited by the nerve agents VX, tabun, sarin, cyclosarin and paraoxon in vitro. It was confirmed that the potency of the compounds is highly sensitive to small structural changes, leading to diminished reactivation potency in many cases. However, the presence of 4-substituted alkylamine substituents (as exemplified with the 4-benzylamine-variant) was tolerated. More surprisingly, the dimeric compounds demonstrated non-typical behavior and displayed some reactivation potency as well. Both findings may open up new avenues for designing more effective non-oxime reactivators.

Abstract
A new series of novel nonquaternary conjugates and non-oxime reactivators for reactivation of both nerve agents and pesticides inhibited hAChE were described in this paper. Conjugates with piperazine linked to the substituted salicylaldoxime emerged as efficient reactivators for VX inhibited hAChE. The in vitro reactivation experiment showed that some of them were equal or more efficient reactivators for pesticides inhibited hAChE than obidoxime. It was also found that some non-oxime derivatives of Mannich phenols displayed obvious reactivation potency for VX, sarin and pesticides inhibited hAChE even in very low concentration. It has been proved that introduction of peripheral site ligands with widespread aromatic system and amide substitutions could increase binding affinity for inhibited hAChE in most cases, which contribute to the reactivation efficiency.

Abstract
BACKGROUND Penehyclidine is a newly developed anticholinergic agent. We aimed to investigate the role of penehyclidine in acute organophosphorus pesticide poisoning (OP) patients. METHODS We searched the Pubmed, Cochrane library, EMBASE, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical literature (CBM) and Wanfang databases. Randomized controlled trials (RCTs) recruiting acute OP patients were identified for meta-analysis. Main outcomes included cure rate, mortality rate, time to atropinization, time to 60% normal acetylcholinesterase (AchE) level, rate of intermediate syndrome (IMS) and rate of adverse drug reactions (ADR). RESULTS Sixteen RCTs involving 1,334 patients were identified. Compared with the atropine- or penehyclidine-alone groups, atropine combined with penehyclidine significantly increased the cure rate (penehyclidine+atropine vs. atropine, 0.97 vs. 0.86, RR 1.13, 95% CI [1.07-1.19]; penehyclidine+atropine vs. penehyclidine, 0.93 vs. 0.80, RR 1.08, 95% CI [1.01-1.15]) and reduced the mortality rate (penehyclidine+atropine vs. atropine, 0.015 vs. 0.11, RR 0.17, 95% CI [0.06-0.49]; penehyclidine+atropine vs. penehyclidine, 0.13 vs. 0.08, RR 0.23, 95% CI [0.04-1.28]). Atropine combined with penehyclidine in OP patients also helped reduce the time to atropinization and AchE recovery, the rate of IMS and the rate of ADR. Compared with a single dose of atropine, a single dose of penehyclidine also significantly elevated the cure rate, reduced times to atropinization, AchE recovery, and rate of IMS. CONCLUSION Atropine combined with penehyclidine benefits OP patients by enhancing the cure rate, mortality rate, time to atropinization, AchE recovery, IMS rate, total ADR and duration of hospitalization. Penehyclidine combined with atropine is likely a better initial therapy for OP patients than atropine alone.

Abstract
Organophosphorus (OP) nerve agents and pesticides present significant threats to civilian and military populations. OP compounds include the nefarious G and V chemical nerve agents, but more commonly, civilians are exposed to less toxic OP pesticides, resulting in the same negative toxicological effects and thousands of deaths on an annual basis. After decades of research, no new therapeutics have been realized since the mid-1900s. Upon phosphylation of the catalytic serine residue, a process known as inhibition, there is an accumulation of acetylcholine (ACh) in the brain synapses and neuromuscular junctions, leading to a cholinergic crisis and eventually death. Oxime nucleophiles can reactivate select OP-inhibited acetylcholinesterase (AChE). Yet, the fields of reactivation of AChE and butyrylcholinesterase encounter additional challenges as broad-spectrum reactivation of either enzyme is difficult. Additional problems include the ability to cross the blood brain barrier (BBB) and to provide therapy in the central nervous system. Yet another complication arises in a competitive reaction, known as aging, whereby OP-inhibited AChE is converted to an inactive form, which until very recently, had been impossible to reverse to an active, functional form. Evaluations of uncharged oximes and other neutral nucleophiles have been made. Non-oxime reactivators, such as aromatic general bases and Mannich bases, have been developed. The issue of aging, which generates an anionic phosphylated serine residue, has been historically recalcitrant to recovery by any therapeutic approach-that is, until earlier this year. Mannich bases not only serve as reactivators of OP-inhibited AChE, but this class of compounds can also recover activity from the aged form of AChE, a process referred to as resurrection. This review covers the modern efforts to address all of these issues and notes the complexities of therapeutic development along these different lines of research.
