A series of oxyanilinium-based AChE inhibitors have been synthesised and tested for the reversal of vecuronium-induced neuromuscular block. Several compounds, for example 2- hydroxy-and 2-methoxy-N, N-dimethyl-N-allylanilinium bromide (3 and 6) showed comparable reversal potencies to edrophonium and clean in vivo cardiovascular profiles.
