The invention relates to the technical field of
medicinal chemistry, in particular to a 2-methyl-2-azabicyclo [3.2. 1]
octane derivative which has a structure as shown in a general formula I or a general formula II or pharmaceutically acceptable salt, solvate,
hydrate, isomer or
prodrug of the 2-methyl-2-azabicyclo [3.2. 1]
octane derivative, and a preparation method and application of the 2-methyl-2-azabicyclo [3.2. 1]
octane derivative. As an
acetylcholine receptor agonist, the compound shows
high activity and
high selectivity to M3
receptor subtypes. In-vitro experiments show that under the concentration of 40 mu M, the
receptor excitation rate of the compound (such as 9a, 10a and the like) exceeds 95%, and is obviously superior to that of a
positive control drug Aceclidine (48.65%). Due to the characteristic, the compound can generate a powerful
pupil contraction pinhole effect by efficiently exciting an eye iris M3 receptor so as to improve
near vision, and meanwhile, stimulation to ciliary muscles and related side effects are expected to be reduced due to
high selectivity of the compound.
