摘要:
The present invention relates to a novel piperazinyl-propyl-pyrazole derivative, a method of its preparation and a pharmaceutically acceptable composition comprising the same. The novel piperazinyl-propyl-pyrazole derivative of the present invention has superior selective affinity for dopamine D4 receptor, can effectively inhibit psychotic behavior (cage climbing) induced by apomorphine, and has relatively low adverse effects in mouse rotarod test. Therefore, it can be developed as a therapeutic agent for the treatment and prevention of central nervous system (CNS) disorders, in particular, schizophrenia, attention deficit hyperactivity disorder, depression, stress diseases, panic disorder, phobia, obsessive-compulsive disorder, posttraumatic stress disorder, cognitive disorder, Alzheimer's disease, Parkinson's disease, anxiety, paraphrenia, mania, seizure disorder, personality disorder, migraine, drug addiction, alcohol addiction, obesity, eating disorder, and sleeping disorder.
摘要:
The present invention relates to a synthesis of a 7-membered carbocyclic compound having diexomethylene groups, more particularly to a synthesis of a 7-membered carbocyclic compound having diexomethylene groups, a novel compound having the structure represented by the following Chemical Formula 1, from trimethylsilanylmethyl-allenol derivative by the intramolecular Prins cyclization using Lewis acid. The 7-membered carbocyclic compound is a useful intermediate for synthesis of other multicyclic compounds. In Chemical Formula 1, R1 is a C1 to C6 alkyl group, and R2 and R3 is respectively a hydrogen atom, or R1, R2 and R3 may be connected with neighboring substituents to form a 5 to 10-membered aliphatic or aromatic ring.

摘要:
The present invention relates to a novel medicinal use of pyrazolopyrimidine compounds having superior effect as serotonin 5-HT2C receptor ligand thus being useful for the prevention and treatment of central nervous system (CNS) diseases. Accordingly, the pharmaceutical composition comprising pyrazolopyrimidine compounds and their pharmaceutically acceptable salts as active ingredients are useful for the prevention and treatment of serotonin 5-HT2C-related central nervous system diseases such as obesity, depression, anxiety and withdrawal symptoms due to drug abuse.
摘要:
Disclosed are isoindolinone derivatives, represented by Chemical Formula 1, having inhibitory activity against T-type calcium channels, pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition comprising the same as an active ingredient. wherein R1˜R6 are as defined in the specification.
摘要:
Disclosed are cis-2,6-disubstituted tetrahydropyran derivatives represented by Chemical Formula 1 and a preparation method thereof. The tetrahydropyran derivatives can be prepared by Prins-reacting tetrahydropyran derivatives with homopargylicalcohol derivatives in the presence of trimethylsilyltriflate. The tetrahydropyran derivatives with cis-substituents at both C2 and C6 positions of the tetrahydropyran ring are useful as intermediates for use in the synthesis and development of therapeutically effective, naturally occurring compounds. (wherein, R1, R2 and R3 are as defined in the specification.)
摘要:
The present invention relates to a tetrahydrofuran compound having cis substituents, the derivatives thereof and a process for preparing the same, and in particular relates to a dihydrofuran-3-ylidene triflate compound having cis substituents at C2 and C5 positions prepared through Prins-type cyclization using a homopropargylic alcohol derivative as a starting material in the presence of Lewis acid catalyst, a tetrahydrofuran compound having cis substituents at C2, C3 and C5 positions prepared through the hydrolysis of triflate group in the derivatives of the dihydrofuran-3-ylidene triflate compound, and a preparation method thereof.The derivatives and the target tetrahydrofuran compound prepared according to the present invention are hydrofuran compounds with novel structures having cis substituents at C2, C3 and/or C5 positions, which are useful as a derivative for synthesizing drugs such as an antagonist for neurokinin receptor.
