Optimization of N-benzyl-benzoxazol-2-ones as receptor antagonists of macrophage migration inhibitory factor (MIF)
摘要:
The cytokine MIF is involved in inflammation and cell proliferation via pathways initiated by its binding to the transmembrane receptor CD74. MIF also exhibits keto-enol tautomerase activity, believed to be vestigial in mammals. Starting from a 1 mu M hit from virtual screening, substituted benzoxazol-2-ones have been discovered as antagonists with IC50 values as low as 7.5 nM in a tautomerase assay and 80 nM in a MIF-CD74 binding assay. Additional studies for one of the potent inhibitors demonstrated that it is not a covalent inhibitor of MIF and that it attenuates MIF-dependent ERK1/2 phosphorylation in human synovial fibroblasts.

[Problems] To provide a pharmaceutical, in particular a compound which can be used as a therapeutic agent for irritable bowel syndrome (IBS).
[Means for Solving Problems] It was found that a tetrahydroisoquinolin-1-one derivative having an amide group at the 4-position or a pharmaceutically acceptable salt thereof has an excellent bombesin 2 (BB2) receptor antagonistic action. It is also found that the tetrahydroisoquinolin-1-one derivative is highly effective on bowel movement disorders. From the above, the tetrahydroisoquinolin-1-one derivative of the present invention is useful as a therapeutic agent for diseases associated with a BB2 receptor, in particular IBS.
