QSAR analysis of oxime reactivation of AChE inhibited by these OP compounds and others suggested that the presence of both a large substituent ( i . e . , <= the size of dimethylamine ) and an alkoxy substituent in the structure of OP compounds is the common feature that results in resistance to oxime reactivation of OP - AChE conjugates whether the OP is a phosphate , phosphonate or phosphoramidate .
