There is provided an inhibitor that inhibits casein kinase 1δ and casein kinase 1ε, and thus, there is also provided a pharmaceutical agent useful for the treatment and/or prevention of a disease, with the pathological condition of which the mechanism of activation of casein kinase 1δ or casein kinase 1ε is associated. Particularly, the above-described inhibitor is used to provide a pharmaceutical agent useful for the treatment of circadian rhythm disorder (including sleep disorder), central neurodegenerative disease, and cancer.
An inhibitor of casein kinase 1δ and casein kinase 1ε, which comprises, as an active ingredient, an oxazolone derivative represented by the following general formula (1), a salt thereof, a solvate thereof, or a hydrate thereof:
[wherein, in the formula (1), each of R1 and R2 independently represents any one of a substituted or unsubstituted 6-membered or 5-membered heterocyclic group optionally having a condensed ring, a substituted or unsubstituted aromatic hydrocarbon group optionally having a condensed ring, and a substituted or unsubstituted aromatic hydrocarbon lower alkyl group or aromatic hydrocarbon lower alkenyl group optionally having a condensed ring.]
本发明提供了一种抑制酪氨酸激酶1δ和酪氨酸激酶1ε的抑制剂,因此还提供了一种用于治疗和/或预防与酪氨酸激酶1δ或酪氨酸激酶1ε的激活机制相关的疾病的药物剂。特别地,上述抑制剂用于提供一种用于治疗昼夜节律紊乱(包括睡眠障碍)、中枢神经退行性疾病和癌症的药物剂。
一种酪氨酸激酶1δ和酪氨酸激酶1ε的抑制剂,包括以下通式(1)所表示的噁唑酮衍生物作为活性成分,其盐、溶剂合物或水合物。[在式(1)中,R1和R2各自独立地表示取代或未取代的6元或5元杂环基,可选地具有缩环,取代或未取代的芳香族碳氢基,或取代或未取代的芳香族碳氢低烷基或芳香族碳氢低烯基,可选地具有缩环。]
