  Compounds useful as GnRH receptor antagonists are provided. The present inventors have further examined propane-1,3-dione derivatives and confirmed as a result that a propane-1,3-dione having 2-(1,3-dihydro-2H-benzimidazol-2-ylidene), or a compound which has benzene or thiophene ring substituted with a group derived from 1-hydroxymethyl, shows excellent availability, in addition to its excellent GnRH receptor antagonism, thereby accomplishing the invention. Since the compound of the invention shows excellent availability, in addition to its strong GnRH receptor antagonism, it can be expected that it exerts superior drug effect in the living body, and it is useful for the treatment of sex hormone dependent diseases such as prostate cancer, breast cancer, endometriosis, uterine leiomyoma, benign prostatic hypertrophy and the like. In addition, since the compound of the invention is excellent in metabolic stability in human and also is less in drug interaction, it has more desirable properties as a medicament to be used for the aforementioned diseases.

  本发明提供了作为GnRH受体拮抗剂有用的化合物。本发明人进一步研究了丙酮酸-1,3衍生物，并确认结果为具有2-（1,3-二氢-2H-苯并咪唑-2-基）的丙酮酸-1,3或具有苯环或噻吩环，其被1-羟甲基衍生物取代的化合物，除了具有优异的GnRH受体拮抗作用外，还具有出色的可用性，从而完成了该发明。由于该发明的化合物除了具有强大的GnRH受体拮抗作用外，还具有出色的可用性，因此可以预期它在生物体内发挥出卓越的药效，并且对于治疗性激素依赖性疾病，例如前列腺癌，乳腺癌，子宫内膜异位症，子宫肌瘤，良性前列腺增生等，具有用处。此外，由于该发明的化合物在人体内具有优异的代谢稳定性并且药物相互作用较少，因此作为用于上述疾病的药物具有更理想的性质。
