  • Patent number: 9290582
    Abstract: The present invention relates to the field of genetic engineering drugs, particularly to a novel B cell activating factor (BAFF) antagonist and use thereof. The technical problem to be solved by the invention is to find a new and effective selection for the prevention and treatment of autoimmune diseases. The B cell activating factor receptor antagonist is mainly obtained by the fusion of the domain 2 binding BAFF in TACI receptor and the domain binding BAFF in Br3 receptor, and it also can be fused with a Fc segment of IgG1 to obtain a new fusion protein molecule. Experiments indicate that said new fusion protein molecule has the function of BAFF antagonist, which can treat the autoimmune diseases, and supply a new and effective selection for the prevention and treatment of the autoimmune diseases.

  • Patent number: 8680097
    Abstract: The invention discloses benzothiophene alkanol piperazine derivatives and their use as antidepressants. The invention discloses the said benzothiophene alkanol piperazine derivative having triple inhibition effect on the reuptake of 5-HT, NA and DA. Compared with clinical used antidepressants so far having single target, e.g. desipramine and fluoxetine, and clinical used antidepressants so far having double targets, e.g venlafaxine and duloxetine, the said benzothiophene alkanol piperazine derivatives of the present invention may have a broader indication range and less toxic and side effects to nervous system. The benzothiophene alkanol piperazine derivatives are the compounds with the following formula or their pharmaceutically acceptable salts, wherein Ar1, R1-R4, X, Y, m and n have the same definition as defined in claim 1.

  • Patent number: 8609137
    Abstract: The present invention discloses a novel soft capsule of butylphthalide and a process for preparing the same. The soft capsule of butylphthalide is composed of a capsule wall material and a drug-containing oil, wherein the drug-containing oil is essentially composed of butylphthalide and a vegetable oil as the diluent in a weight ratio of about 1:0˜10. The capsule wall material is composed of a capsule wall matrix, a plasticizer and water in a weight ratio of 1:0.2˜0.4:0.8˜1.3. The soft capsule of butylphthalide described in the present invention can mask the strong and special flavor of butylphthalide, and overcome the difficulties associated with formulating oily active ingredient into other oral formulation. The disintegration time of the soft capsule satisfies the requirement of Pharmacopoeia of P.R. China.
