摘要:
The present invention relates to a barbituric acid derivative shown in formula (I) (wherein R or R1 independently represents a hydrogen atom, a susbstituted or not substituted alkyl group or alkenyl group of C¿1? - C15, a substituted or not substituted arylmethyl group, and substituted or not substituted aryl group, and R?2¿ represents substituted or not substituted alkyl group or alkenyl group of C¿1? - C15, a substituted or not substituted arylmethyl group, and substituted or not substituted aryl group). The barbituric acid derivative of the present invention has a strong inhibiting activity to bone resorption and is useful as a preventive and therapeutic agent for diseases affecting bone and cartilage.
摘要:
A protein having amino acid sequence in SEQ ID No.:1 of the Sequence Listing derived from human MP52, and a dimer protein thereof. A homodimer protein described above can be obtained by constructing a plasmid containing DNA coding amino acid sequence in SEQ ID No.:1 of the Sequence Listing with a methionine at the N-terminus, introducing the plasmid into E . coli for transformation, solubilizing inclusion bodies obtained by culturing the transformant, purifying the monomer protein from the solubilized solution, refolding the monomer protein into a dimer protein and purifying the same. The homodimer protein described above is useful as a pharmaceutical composition for treating cartilage and bone diseases.
