摘要:
Thiazole compounds for inhibiting the activity of phosphodiesterase 4, the production of tumor necrosis factor alpha, and the production of interleukin 4. The compounds of the invention are represented by general formula (1): wherein A is any one of the following groups (i)-(iii): (i) —CH(OH)—B— wherein B is a C1-6 alkylene group; (ii) —COCH(COOR3)-Bb- wherein R3 is a C1-6 alkyl group and Bb is a C1-6 alkylene group; and (iii) -Bc- wherein Bc is a C2-6 alkylene group, and include optical isomers and salts of the compounds.
摘要:
The present invention provides a oxazole compound represented by Formula (1), or a salt thereof: wherein R1 is an aryl group which may have one or more substituents; R2 is an aryl group or a nitrogen atom-containing heterocyclic group each of which may have one or more substituents; and W is a divalent group represented by —Y1-A1- or —Y2—C(═O)— wherein Y1 is a group such as —C(═O)—, A1 is a group such as a lower alkylene group, and Y2 is a group such as a piperazinediyl group. The oxazole compound has a specific inhibitory action against phosphodiesterase 4.
