描述 | Methylbenactyzium Bromide is a muscarinic acetylcholine receptor (mAChR) inhibitor. Propantheline was highly bound to the membrane and this binding was inhibited to varying extents by several quaternary ammonium compounds. Mepenzolate and methylbenactyzium inhibited it significantly[2]. Methylbenactyzium bromide was extracted from urine with ODS-cartridge (Sep-Pak C18), then spotted onto a silica gel 60 F254 TLC plate. After development, the separated spot of methylbenactyzium bromide was scraped and wrapped with a ferromagnetic foil without extraction by any organic solvents. A calibration graph prepared by absolute calibration method showed a good linearity over the concentration range of 1-75 micrograms/spot for methylbenactyzium bromide. The coefficient of variation obtained for eleven replicate analyses of the 3 micrograms/spot of standard methylbenactyzium bromide was 3.8%. The detection limit of this compound by this procedure was 0.1 micrograms/spot[3]. |
