摘要:
Novel compounds exhibiting an excellent acetylcholinesterase inhibiting effect, i.e., fluorides of 4-substituted piperidine derivatives as represented by general formula (I), pharmacologically acceptable salts of the same, and hydrates of both (exclusive of 1-benzyl-4-[(5,6-dimethoxy-2-fluoro-1-indanon)-2-yl]methylpiperidine, pharmacologically acceptable salts of the same, and hydrates of both). In formula (I), wherein R1 is (II) or the like; and R2 is (III) (wherein A is a benzene ring or a heterocycle), or the like.
摘要:
The present invention provides a novel compound having an excellent acetylcholinesterase inhibitory effect. That is, it provides a 4-substituted piperidine compound fluoride represented by the following formula, a pharmaceutically acceptable salt thereof or hydrates thereof (provided that 1-benzyl-4-[(5,6-dimethoxy-2-fluoro-1-indanon)-2-yl]methylpiperidine, a pharmaceutically acceptable salt thereof and hydrates thereof are excluded). wherein R 1 and R 2 represent substituents.
摘要:
The present invention provides a novel compound which shows the excellent acetylcholinesterase inihibitory action and is useful as a medicament, especially as an agent for preventing, treating or improving various kinds of senile dementia, Alzheimer-type senile dementia, cerebrovascular dementia, attention deficit hyperactivity disorder etc., and a process for producing it. Namely, it provides 1-benzyl-4-[(5,6-dimethoxy-2-fluoro-1-indanon)-2-yl] methylpiperidine represented by the formula: or a pharmaceutically acceptable salt thereof.
