2019年3月28日 · The threat of a deliberate release of chemical nerve agents has underscored the need to continually improve field effective treatments for these types of poisonings. The oxime containing HLö-7 is a potential second-generation therapeutic reactivator. A synthetic process for HLö-7 is detailed with improvements to the DIBAL reduction and ion exchange steps. HLö-7 was visualized for the first ...

Reactivating potency of AChE inhibited by soman, sarin, cyclosarin, and VX is decreased in the order of HLO7>HI-6>obidoxime>2-PAM [1]. Therapy of intoxicated rat with GV demonstrated best antidotal effect of combination of benactyzine, atropine and HI-6 [149].

Southwest Research Institute Previous methods to synthesize bis-pyridinium organophosphorous nerve agent (OPNA) antidotes like HLö7 DMS required the use of the chemical linkers bis(2-chloromethyl) ether (BCME) or bis(2-methylsulfonoxymethyl) ether (BMME). Not only are these compounds difficult to prepare and are unstable, they are extremely carcinogenic, with an estimated OSHA exposure limit ...

Abstract HLö 7 dimethanesulfonate (1- [ [ [4- (aminocarbonyl)pyridinio]methoxy]methyl]-2,4-bis [ (hydroxyimino)methyl]pyridinium dimethanesulfonate) is a broad-spectrum reactivator against highly toxic organophosphorus compounds. The compound was synthesized by a new route with the carcinogenic bis (chloromethyl)ether being substituted by the non-mutagenic bis (methylsulfonoxymethyl)ether ...

Abstract (1) The efficacy of the oxime HLö7 and currently used oximes (pralidoxime, obidoxime, HI-6) to reactivate acetylcholinesterase inhibited by various nerve agents (sarin, tabun, cyclosarin, VX) was tested by in vitro methods. (2) Both H oximes (HLö-7, HI-6) were found to be more efficacious reactivators of sarin and VX-inhibited acetylcholinesterase than pralidoxime and obidoxime. On ...

HLö-7 was visualized for the first time within the active site of human acetylcholinesterase and its relative ex vivo potency confirmed against various nerve agents using a phrenic nerve hemidiaphragm assay. The threat of a deliberate release of chemical nerve agents has underscored the need to continually improve field effective treatments for these types of poisonings. The oxime containing ...

Searching for the universal oxime, which could be able to reactivate acetylcholinesterase inhibited by various nerve agents is still topic of high interest. In this contribution, oxime HLö-7 ...
