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.
本发明旨在提供一种作为GnRH受体拮抗剂有用的化合物。发明人进一步研究了丙酮酸1,3-二酮衍生物。结果,他们证实,在2-(1,3-二氢-2H-苯并咪唑-2-基亚胺)具有苯环或噻吩环的衍生物中,取代为—SO2—R3基团的化合物具有出色的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,因此对于治疗性激素依赖性疾病,特别是GnRH相关疾病非常有用。此外,由于本发明的化合物在人体内具有出色的代谢稳定性和较少的药物相互作用,因此作为用于上述疾病的药物具有良好的特性。
