摘要:
An object of the present invention is to provide DNA which regulates the expression of miR-140, a reporter vector which contains the DNA, cells and animals into which the reporter vector is introduced and a screening system for drugs which control the expression of miR-140 and is also to contribute in the development of new therapeutic agents for cartilage diseases such as osteoarthritis and intervertebral disk degeneration using the screening system. The DNA sequence according to the present invention is able to express any gene in a site where miR-140 is expressed and, in addition, it is also able to be utilized for screening a drug which regulates the expression of miR-140. Moreover, the drug that is selected by the screening system of the present invention is expected as a therapeutic agent for cartilage diseases accompanied by abnormality of cartilage.

An object of the present invention is to provide a preventive or therapeutic agent for inflammatory diseases or degenerative intervertebral disk diseases. A coumarin derivative or a pharmaceutically acceptable salt or hydrate thereof which is an active ingredient of the preventive or therapeutic agent of the present invention exhibits an excellent suppressive action in a pharmacological test where production of inflammation-related factor such as inflammatory cytokine or fibrosis-related factor as an index. Moreover, said compound also exhibits an excellent suppressive action to pulmonary fibrosis model animals and degenerative intervertebral disk disease model animals. Accordingly, the present invention is very useful as a preventive or therapeutic agent for inflammatory diseases and degenerative intervertebral disk diseases.
摘要:
An object of the present invention is to provide a drug which is effective for prophylaxis or therapy of peripheral nerve disorder occurred as a side effect of the administration of anti-cancer agents. The present invention is to provide a drug containing an ester of C 10 fatty acid as an active ingredient for prophylaxis or therapy of peripheral nerve disorder induced by administration of a drug containing at least one of anti-cancer agents. The drug of the present invention containing the compound as an active ingredient is highly useful as a drug for prophylaxis or therapy of peripheral nerve disorder induced by administration of anti-cancer agents.
摘要:
The purpose of the present invention is to provide a novel coumarin derivative or a pharmaceutically acceptable salt thereof and also to provide a pharmaceutical agent containing such a compound as an active ingredient. The coumarin derivative of the present invention or a pharmaceutically acceptable salt thereof exhibits an excellent suppressive action to the destruction of cartilage and suppressive action to the proliferation of synovial cells in a pharmacological test where the release of sulfated glycosaminoglycans (sGAG) and the proliferation of synovial cells are used as indicators whereby it is very useful as an active ingredient of a pharmaceutical composition such as a preventive or therapeutic agent for arthropathy such as osteoarthritis or chronic rheumatoid arthritis.
摘要:
An object of the present invention is to provide an analgesic effective in a prophylactic or a therapy for various pain diseases. The present invention is to provide an analgesic containing at least one member selected from a trans-2-decenoic acid derivative represented by the formula (1) and a pharmaceutically acceptable salt thereof as an active ingredient:
(In the formula, Y is -O-, -NR- or -S-, R is hydrogen atom, alkyl group, dialkylaminoalkyl group or the like and W is a substituent such as dialkylaminoalkyl group). The analgesic of the present invention containing the compound as an active ingredient is highly useful as a prophylactic or therapeutic agent for various pain diseases such as the pain caused by osteoarthritis (e.g., knee osteoarthritis and hip osteoarthritis).
摘要:
The object of the present invention is to provide a test method using a novel administration method of an extract from inflamed tissues inoculated with vaccinia virus or a preparation containing the extract. It has been demonstrated that by sustainedly administering an extract from inflamed tissues inoculated with vaccinia virus or a preparation containing the extract by using a continuous administration device according to the present invention, a comparable effect is exerted at a very low dose compared with conventional administration methods such as oral administration. Therefore, the present invention can provide a test method using animals requiring less burden on a researcher, a treatment of patient at a low dose, and the like.
