  • Patent number: 8906395
    Abstract: A pharmaceutical composition includes lipid nanoparticles which include two or more of a phospholipid, cholesterol, and an ionic lipid, and a tricyclic derivative, wherein the solubility of the tricyclic derivative is improved. It is possible to solubilize a partially soluble tricyclic derivative in a high concentration even without using a solubilization aid harmful to the human body, to maintain improved solubility even if water is added for the use as an injection, and to show stability even if stored for a long time, by preparing lipid nanoparticles. Therefore, the lipid nanoparticles of the present invention can be used for preparing a pharmaceutical preparation containing a partially soluble tricyclic derivative as an active ingredient.

  • Patent number: 8815891
    Abstract: The present invention relates to a novel tricyclic derivative with efficient inhibitory activity against poly(ADP-ribose)polymerases (PARP) or pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition containing the same. The tricyclic derivative of the invention is useful for the prevention or treatment of diseases caused by excess PARP activity, especially neuropathic pain, neurodegenerative diseases, cardiovascular diseases, diabetic nephropathy, inflammatory diseases, osteoporosis, and cancer, by inhibiting the activity of poly(ADP-ribose)polymerases.

  • Patent number: 8334277
    Abstract: 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.
