The changes in cholinesterase activity in tissues were evaluated and compared with the reactivation potential of reactivators. As reactivators, (E)-1-(4-carbamoylpyridi¬nium-1-yl)-4-{4-[(hydroxyimino)methyl]pyridinium-1-yl}but-2-ene dibromide (K203) and common 1,3-bis{4-[(hydroxyimino)methyl]pyridinium-1-yl}-2-oxapropane dichloride (obidoxime) were used. The reactivation of both oximes was monitored in blood and blood plasma. The reactivation of tabun-inhibited acetylcholinesterase (AChE) was higher using the newly synthesized K203.
