  • 6-Alkylamino-2-methyl-2?-(N-methyl substituted sulfonamido)methyl-2H-1-benzopyran derivative as anti-inflammatory inhibitor
    Patent number: 7371874
    Abstract: The present invention relates to a noble 6-alkylamino-2-methyl-2?-(N-methyl substituted sulfonamido)methyl-2H-1-benzopyran derivative, a method for preparing the same with high efficiency using a parallel synthetic method, one of combinatorial chemical synthetic techniques, and a use of the novel compound showing a high inhibitory effect to 5-lipoxygenase (5-LO) activity for preventing and treating leukotriene (LTA4, B4, C4, D4) activation-related diseases such as inflammatory diseases, rheumatoid arthritis, colitis, asthma and psoriasis.

  • 6-alkylamino-2,2?-disubstituted-7,8-disubstituted-2H-1-benzopyran derivatives as 5-lipoxygenase inhibitor
    Patent number: 7368575
    Abstract: When a multi-step process reaction is carried out in a solution, it generally requires several treatments and purification procedures to go through with after the reaction, however, the inventive method for preparing 2,2?-disubstituted-3,4-dihydro-7,8-disubstituted-6-amino benzopyran derivative using a solid-phased synthetic method simplifies the treatment and purification procedures after the reaction, which makes possible to efficiently construct numerous drug-like libraries.
