| 20090269747 | Marker Genes Based on Amiodarone Treatment for Screening of Drug Inducing Toxicity and Screening Method Therefor - The present invention relates to a marker gene for screening of drug candidates inducing pulmonary toxicity and a screening method using the same, more precisely a marker gene up- or down regulated by amiodarone which is a drug inducing pulmonary toxicity and a method for screening drug candidates inducing pulmonary toxicity using the same. The marker gene of the present invention can be effectively used for monitoring and identifying drugs or chemical having high risk of inducing pulmonary toxicity and can be used as an effective tool for examining the mechanism of amiodarone which causes pulmonary toxicity and side effects. | 10-29-2009 |
| 20090291855 | METHOD FOR CONFIRMING THE EXPOSURE ON CHRYSENE - The present invention relates to a method for confirming the exposure on chrysene using a DNA fragment whose expression is increased or decreased specifically when it is exposed to chrysene. The method of the present invention is effective in determination of risk by chrysene and monitoring the chrysene exposure, so that it can be effectively used as a tool for examining the mechanism of chrysene induced toxicity. | 11-26-2009 |
| 20100063281 | DIPHENYL AMINE DERIVATIVES HAVING LUMINESCENCE PROPERTY - The present invention relates to diphenyl amine derivatives having luminescent properties, and particularly to diphenyl amines substituted with various electron-donating or electron-withdrawing groups. The compounds of the present invention show blue or blue-green luminescence, and luminescence of the compounds herein can be achieved by UV or visible light, thus being useful as a fluorescent dye or fluorescent material for an organic electroluminescence device or display. | 03-11-2010 |
| 20110118127 | MARKER GENES FOR SCREENING OF DRUG-INDUCED TOXICITY IN HUMAN CELLS AND SCREENING METHOD USING THE SAME - The present invention relates to a marker gene for screening a drug inducing toxicity in human and a screening method using the same. More precisely, the invention relates to a microarray on which marker genes up-or down-regulated specifically by 16 drugs inducing pulmonary toxicity, teratogenicity, nephrotoxicity, cardiotoxicity or mutation (Methotrexate, Nitrofurantoin, Amiodarone, Carbamazepine, Valproic acid, Thalidomide, Cisplatin, Gentamycin, Amphotericine, Furylfuramide, N-nitroso-N-methylurea, methylmethanesulfonate, 4-nitroquinoline-N-oxide, 2-nitrofluorene, Doxorubicin and Daunorubicin) are integrated, a kit comprising the said microarray, and a screening method of a drug inducing toxicity in human using the same. The DNA microarray containing the marker gene of the present invention facilitates the construction of Toxtarget Array for screening a drug inducing toxicity in human using drug-specific genes, suggesting that this chip can be effectively used for monitoring drugs or chemicals carrying toxicity to human or determining risks thereof and also it can be used as a tool for examining mechanisms of toxicity/side effects caused by the drugs. | 05-19-2011 |
| 20110190155 | MARKER GENES BASED ON AMIODARONE TREATMENT FOR SCREENING OF DRUG INDUCING PULMONARY TOXICITY AND SCREENING METHODS USING THE SAME - The present invention relates to a marker gene for screening of drug candidates inducing pulmonary toxicity and a screening method using the same, more precisely a marker gene up- or down regulated by amiodarone which is a drug inducing pulmonary toxicity and a method for screening drug candidates inducing pulmonary toxicity using the same. The marker gene of the present invention can be effectively used for monitoring and identifying drugs or chemical having high risk of inducing pulmonary toxicity and can be used as an effective tool for examining the mechanism of amiodarone which causes pulmonary toxicity and side effects. | 08-04-2011 |
