It is intended to provide a compound useful as a GnRH receptor antagonist. The inventors further investigated propane-1,3-dione derivatives. As a result, they confirmed that a compound having a benzene ring or a thiophene ring substituted with a group represented by -SO2-R3 in a propane-1,3-dione derivative having 2-(1,3-dihydro-2H-benzimidazol-2-ylidene) has an excellent GnRH receptor antagonistic effect and accomplished the present invention. Because the compound of the present invention has a potent GnRH receptor antagonistic effect, it is useful for the treatment of sex hormone-dependent diseases, particularly GnRH-related diseases. Further, because the compound of the present invention has an excellent metabolic stability in human and few drug interactions, therefore it has preferable characteristics as a pharmaceutical used for the above-mentioned diseases.
其目的是提供一种可用作 GnRH 受体拮抗剂的化合物。发明人进一步研究了丙烷-1,3-二酮衍生物。结果,他们证实在具有 2-(1,3-二氢-2H-苯并咪唑-2-亚基)的丙烷-1,3-二酮衍生物中,具有被-SO2-R3 所代表的基团取代的苯环或噻吩环的化合物具有极好的 GnRH 受体拮抗作用,并完成了本发明。由于本发明的化合物具有强效的 GnRH 受体拮抗作用,因此可用于治疗性激素依赖性疾病,特别是 GnRH 相关疾病。此外,由于本发明的化合物在人体中具有极好的代谢稳定性,且药物相互作用少,因此作为用于治疗上述疾病的药物具有更佳的特性。
