摘要:
The present invention relates to a method for preparing a tricyclic derivative, and more particulary, to a method for preparing a tricyclic derivative inetermediate with high yield and purity, the method including: introducing a hydroxy group by esterifying and substituting 2-fluoroisophthalic acid compound; introducing a piperidyl group; introducing a hydroxy group through reduction reaction; and then hydrolyzing the resultant compound, and to a method for preparing the tricyclic derivative using said intermediate. According to the method of the present invention, it is possible to provide a tricyclic derivative and an intermediate thereof with high productivity and economic feasibility as well as high purity and yield, by purifying a compound using re-crystallization unlike typical methods of using column chromatography. In addition, the method of the present invention can be usefully used for industrial mass production because sodium borohydride or lithium aluminum hydride with low risk of a fire is used unlike typical methods of using lithium borohydride which is not industrially applicable due to high risk of a fire.

The present invention relates to a composition for preventing or treating metabolic diseases, containing 10-ethoxy-8-(morpholinomethyl)-2,3,4,6-tetrahydrobenzo[h][1,6]naphthyridin-5(1H)-one, a pharmaceutically acceptable salt thereof, a hydrate thereof, or a salt hydrate thereof as an active ingredient. Due to an adipocyte differentiation inhibitory effect, a fat accumulation inhibitory effect, an NAFLD inhibitory effect, and an NASH-induced fibrosis inhibitory effect of the composition, it is possible to prevent or treat metabolic diseases including nonalcoholic steatohepatitis (NASH), NASH-associated liver fibrosis, nonalcoholic fatty liver (NAFL), and NAFLD-associated liver fibrosis, fatty liver, and obesity.
摘要:
Disclosed is a method for producing a spherical neural mass having suppressed teratoma formation. When using the spherical neural mass produced according to the method of the present disclosure, the purity of the neuronal progenitor cells may be improved, the teratoma formation may be suppressed, and the viability and recovery percentage of the cell may be increased.
摘要:
The present invention relates to a novel {4-[2-(dimethylamino)-1-(1-hydroxycyclohexyl)ethyl]phenoxy}phosphate or a pharmaceutically acceptable salt thereof, a production method therefor and a pharmaceutical composition for preventing and treating central nervous system disorders which contains the same as an active component. The novel {4-[2-(dimethylamino)-1-(1-hydroxycyclohexyl)ethyl]phenoxy}phosphate or a pharmaceutically acceptable salt thereof according to the present invention can beneficially be used to prevent and treat central nervous system disorders since it exhibits an equivalent biological and pharmacological activity to venlafaxine and salts thereof which are known in the field, it has very little toxicity, and, in particular, it is outstandingly soluble in water as compared with prior-art venlafaxine derivatives.
