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.

The oximes pralidoxime (2-PAM), its dimethanesulphonate salt derivative P2S, and obidoxime (toxogonin) are currently licensed and fielded for the treatment of chemical warfare (CW) organophosphorous (OP) nerve agent poisoning. While they are effective against several of the identified threat CW

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

Environmental toxicology and pharmacology, 32(1), 75-81 (2011-07-27)
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
T Seeger et al.
Toxicology letters, 206(1), 72-76 (2011-08-02)
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
C G Rousseaux et al.
Canadian journal of physiology and pharmacology, 67(10), 1183-1189 (1989-10-01)
HI-6 is an oxime experimentally developed for reactivation of previously untreatable soman-phosphorylated acetylcholinesterase. It has been shown to be effective in restoring acetylcholinesterase activity after poisoning with other "nerve agents" namely VX and sarin; however, its antidotal qualities for the
