The primary toxic mechanism of organophosphorus compounds, i.e. nerve agents or pesticides, is based on the irreversible inhibition of acetylcholinesterase. In consequence of the impaired hydrolysis, the neurotransmitter acetylcholine accumulates in cholinergic synapses and disturbs functional activity of nicotinic and muscarinic acetylcholine receptors by overstimulation and subsequent desensitization. The resulting cholinergic syndrome will become acute life-threatening, if not treated adequately. The current standard treatment, consisting of administration of a competitive mAChR antagonist (e...

The three-dimensional (3D) microporous titanium aminoterephthalate MIL-125-NH₂ (MIL: Material of Institut Lavoisier) was successfully isolated as monodispersed nanoparticles, which are compatible with intravenous administration, by using a simple, safe and low-cost synthetic approach (100 °C/32 h under atmospheric pressure) so that for the first time it could be considered for encapsulation and the release of drugs. The nerve agent antidote 2-[(hydroxyimino)methyl]-1-methyl-pyridinium chloride (2-PAM or pralidoxime) was effectively encapsulated into the pores of MIL-125-NH₂ as a result of the interactions between 2-PAM and the pore walls being mediated by π-stacking and hydrogen bonds, as deduced from infrared spectroscopy and Monte Carlo simulation studies...

Prehospital use of hydroxocobalamin as an antidote for cyanide toxicity, a serious complication of smoke inhalation, has yet to be universally adopted in the United States though its efficacy and safety have been demonstrated since 2006. The purpose of this study was to characterize practices of prehospital hydroxocobalamin administration via a survey of emergency medical services (EMS) and to report a case series from an EMS database to track use of hydroxocobalamin. The Fire Smoke Coalition Newsletter emailed a voluntary survey to EMS subscribers regarding hydroxocobalamin use...

Based on the analysis of data from clinical trials it could be postulated that N-acetylcysteine has a positive impact on the treatment of various diseases. However, less is known about specific molecular and physiological mechanisms underlying the reported therapeutic effects. N-acetylcysteine (NAC, N-acetyl-L-cysteine) is an amino acid derivative containing a thiol group. It is a precursor of L-cysteine and glutathione. NAC is well absorbed and safe for the body at doses up to 300 mg per kg of body weight...

Recent in vitro and in vivo studies highlight the strong potential of dimethyl trisulfide (DMTS) as an antidote for cyanide (CN) intoxication. Due to its high oxygen demand, the brain is one of the main target organs of CN. The blood-brain barrier (BBB) regulates the uptake of molecules into the brain. In the literature, there is no data about the ability of DMTS to penetrate the BBB. Therefore, our aim was to test the in vitro BBB penetration of DMTS and its in vivo pharmacokinetics in blood and brain. The in vitro BBB penetration of DMTS was measured by using a parallel artificial membrane permeability assay (BBB-PAMPA), and a triple BBB co-culture model...

5-fluorouracil and capecitabine are chemotherapeutic agents commonly used to treat solid malignancies. Increased susceptibility to 5-fluorouracil or capecitabine, caused by impaired clearance, dihydropyrimidine dehydrogenase deficiency, or other genetic mutations in the enzymes that metabolize 5-fluorouracil can lead to severe life-threatening toxicities and are typically manifested by an early onset of symptoms. We report and discuss the management and outcome of capecitabine toxicity with the recently FDA approved antidote, uridine triacetate (Vistogard), in a 57-year-old female breast cancer patient with homozygous dihydropyrimidine dehydrogenase deficiency who received treatment beyond the recommended 96 h window from the last dose of capecitabine...

Cadmium poisoning has been reported from many parts of the world. It is one of the global health problems that affect many organs and in some cases it can cause deaths annually. Long-term exposure to cadmium through air, water, soil, and food leads to cancer and organ system toxicity such as skeletal, urinary, reproductive, cardiovascular, central and peripheral nervous, and respiratory systems. Cadmium levels can be measured in the blood, urine, hair, nail and saliva samples. Patients with cadmium toxicity need gastrointestinal tract irrigation, supportive care, and chemical decontamination traditional-based chelation therapy with appropriate new chelating agents and nanoparticle-based antidotes...

Neuroprotection from nerve agent such as soman-induced neural damage is a major challenge for existing drugs. Nerve agent exposure can cause many neural effects in survivors arising mainly due to acetylcholinesterase (AChE) inhibition or death within minutes. Unraveling the mechanisms underlying the nerve agent-induced multiple neurological effects is useful to develop better and safe drugs. The present study aimed to understand the molecular response during soman exposure and to evaluate the neuroprotective efficacy of galantamine on nerve agent-induced neurotoxic changes...

Ricin is one of the most feared bioweapons in the world due to its extreme toxicity and easy access. Since no antidote exists, it is of paramount importance to identify the pathways underlying ricin toxicity. Here, we demonstrate that the Golgi GDP-fucose transporter Slc35c1 and fucosyltransferase Fut9 are key regulators of ricin toxicity. Genetic and pharmacological inhibition of fucosylation renders diverse cell types resistant to ricin via deregulated intracellular trafficking. Importantly, cells from a patient with SLC35C1 deficiency are also resistant to ricin...
