Abstract:
The present invention relates to sulfonamide derivatives as a serotonin receptor antagonist and serotonin reuptake inhibitor and a pharmaceutically acceptable salt thereof. The sulfonamide derivatives have serotonin 5-HT 2A and 5-HT 2C receptor antagonizing and serotonin reuptake inhibiting functions, and thus may be efficiently applied to a CNS-related disease such as depression, obesity, psychosis, schizophrenia, suicidal tendency, anxiety, obsessional neurosis, migraine, appetite disorders, sleep disorders, stroke, and withdrawal symptoms caused by drug abuse.
Abstract:
The present invention relates to bicyclic tetrahydrofuran derivatives and a preparation method thereof. Particularly the present invention relates to a process of preparing the above compounds by performing an intramolecular cyclization of tetrahydrofuran-allenol derivatives in the presence of alcohol compound, transitional metal catalyst and carbon monoxide.
Abstract:
The present invention relates to N-benzyl-N-(2-dimethylamino-ethyl)-benzenesulfonamide compounds useful for the treatment of central nervous system (CNS) disorders.
Abstract:
The present invention relates to tricyclic tetrahydrofuran lactone derivatives and a preparation method thereof. Particularly, the present invention relates to a process of preparing the above compounds 'tetrahydrofuran lactone derivatives' by performing an intramolecular cyclization of tetrahydrofuran-allenic acid derivatives in the presence of a phenyl halide, a palladium catalyst and a base.
Abstract:
The present invention relates to ring-fused lactam derivatives with diexomethylene groups and a method of their preparation thereof, more particularly to a novel ring-fused lactam derivatives with diexomethylene groups which is prepared by intramolecular acyliminium cyclization of a hydroxylactam having a trimethylsilylmethyl-allene group in the presence of a Lewis acid and is useful as an intermediate for synthesis of other polycyclic compounds by the Diels-Alder reaction, and a method of their preparation thereof.
Abstract:
The present invention relates to tricyclic tetrahydrofuran derivatives and a preparation method thereof. Particularly, the present invention relates to a process of preparing the above compounds by performing an intramolecular cyclization of tetrahydrofuran-allene derivatives in the presence of metal catalyst and sodium azide (NaN 3 ).

Abstract:
Disclosed are isoindolinone derivatives 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.
Abstract:
Disclosed are cis-2,6-disubstituted tetrahydropyran derivatives 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.
Abstract:
The present invention relates to a novel 1,2-dihydro-1-oxophthalazinyl piperazine compound having biological activity as serotonin receptor antagonist, a preparation method of the compound and a pharmaceutical composition for the treatment and prevention of central nervous system diseases comprising the compound.
Abstract:
Azepine derivatives acting on 5-HT 7 receptors and pharmaceutically acceptable salts thereof are disclosed. The azepine derivatives and the pharmaceutically acceptable salts thereof have high binding affinities for and high antagonistic activities on 5-HT 7 receptors. Due to these advantages, the azepine derivatives and the pharmaceutically acceptable salts thereof can be applied to therapeutic or prophylactic agents for central nervous system diseases, such as depression, migraine, anxiety, pain, inflammatory pain, neuropathic pain, body temperature dysregulation, biorhythm dysregulation, sleep disturbance, and smooth muscle diseases where 5-HT 7 receptors antagonistic activity is required.
