| 549457000 | Tetracyclo ring system having the hetero ring as one of the cyclos | 6 |
| 20090043116 | HETERO-POLYCYCLIC COMPOUNDS, AND COLORING MATTERS, PIGMENTS, DYES, COLOR-CHANGING MATERIAL COMPOSITIONS, AND COLOR-CHANGING FILMS, MADE BY USING THE COMPOUNDS - Provided are novel hetero-polycyclic compounds having a specific structure, color-changing material compositions comprising (A) a fluorescent coloring matter comprising at least one of the hetero-polycyclic compounds described above and (B) a binder material, color-changing films comprising the above hetero-polycyclic compounds, coloring matters comprising the above hetero-polycyclic compounds, and pigments or dyes comprising the hetero-polycyclic compounds described above, and provided are color-changing material compositions which are not deteriorated in a color-changing performance even after used for long time and which are prevented from being unusable due to deposition of coloring matters during storage and color-changing films produced by using the same, and novel hetero-polycyclic compounds, coloring matters and pigments or dyes which actualize them. | 02-12-2009 |
| 20090171105 | METHOD FOR PRODUCTION OF HYDROCHLORIDE 1(10) BETA-EPOXY-13-DIMETHYLAMINO-5,7ALPHA,6,11BETA (H)-GUAIA-3(4)-EN-6,12-OLIDE, THE LYOPHILIZED ANTITUMOR PREPARATION 'ARGLABIN' - The invention refers to a method for production of 1(10)β-epoxy-13-dimethylamino-5,7a,6, 11β(H)-guaia-3(4)-en-6,12-olide hydrochloride, the lyophilized, antitumor preparation having radio-sensitizing and immunomodulating activities, including extraction of the natural raw material endemic plant | 07-02-2009 |
| 20130023676 | LIPHAGAL ENANTIOMERS AND THEIR DERIVATIVES AND PRECURSORS, AND ENANTIOSELECTIVE METHODS OF MAKING THE SAME - Enantioenriched compositions of liphagal and its derivatives and precursors include more than 50 mol % of a first enantiomer based on the total amount of a first and a second enantiomer. A method of making an enantioenriched composition includes catalytic enantioselective alkylation, ring expansion, and intramolecular aryne cyclization. | 01-24-2013 |
