A series of methyllycaconitine (1a, MLA) analogs was synthesized where the (S)-2- methylsuccinimidobenzoyl group in MLA was replaced with a (R)-2-methyl, 2, 2-dimethyl-, 2, 3-dimethyl, 2-phenyl-, and 2-cyclohexylsuccinimidobenzoyl (1b–f) group. The analogs 1b–f were evaluated for their inhibition of [125I] iodo-MLA binding at rat brain α7 nicotinic acetylcholine receptors (nAChR). In order to determine selectivity, MLA and the analogs ...
