General description

HI-6 functions as an antidote for treating intoxication caused by nerve agents. It acts as a potent drug in radiation protection and suppresses oxidative stress. HI-6 prevents the toxicity of the antineoplastic drug irinotecan.

Biochem/physiol Actions

HI-6 is an efficient oxime cholinesterase reactivator that is used as an antidote for organophosphates (Ops) exposure.

An important factor for successful therapy of poisoning with organophosphorus compounds (OP) is the rapid restoration of blocked respiratory muscle function. To achieve this goal, oximes are administered for reactivation of inhibited acetylcholinesterase (AChE). Unfortunately, clinically used oximes, e.g. obidoxime

Control of brain seizures after exposure to nerve agents is imperative for the prevention of brain damage and death. Animal models of nerve agent exposure make use of pretreatments, or medication administered within 1 minute after exposure, in order to

Pigs were administered intramuscularly molar equivalents of HI-6 salts (HI-6 dichloride 10.71 mg/kg and HI-6 DMS 13.59 mg/kg) either with or without hyaluronidase (60 U/kg). Hyaluronidase is supposed to increase tissue permeability and diminishes discomfort caused by the intramuscular injection.

Asoxime (HI-6) is a well known oxime reactivator used for counteracting intoxication by nerve agents. It is able to reactivate acetylcholinesterase (AChE) inhibited even by sarin or soman. The present experiment was aimed to determine markers of oxidative stress represented

Potent organophosphorous (OP) agents, such as VX, are hazardous by absorption through the skin and are resistant to conventional pharmacological antidotal treatments. The residence time of a stoichiometric bioscavenger, human butyrylcholinesterase (huBuChE), in the plasma more closely matches that of
