A series of 3-quinuclidinyl atrolactate [3-(1-azabicyclo[2.2.2]octyl) 2-hydroxy-2-phenylpropionate, QNA] derivatives in which the methyl group of the parent is substituted with a tertiary amino substituent was prepared and tested for antimuscarinic activity. In general, potency was markedly decreased, although the morpholinyl and thiomorpholinyl derivatives retained significant activity. These compounds were also examined for muscarinic receptor subtype selectivity. Their subtype selectivities were comparable to that of (R,R)-QNA. The results of this investigation suggest possible differences in the accessory binding sites of the proteinaceous receptor subtypes.
