The present invention relates to compounds of formula (I), and pharmaceutically acceptable salts thereof,
wherein:
X is CH or N;
one of R1 and R2 is H, and the other is selected from OR6, SR6, NR6R7, N3, Me, Et, CF3, SOR8 and SO2R8;
R3 is selected from tert-butylmethyl, iso-propylmethyl, sec-butyl, tert-butyl, cyclopentyl and cyclohexyl;
R4 is optionally substituted C1-8 alkyl or optionally substituted C3-8 cycloalkyl;
R6 and R7 are each independently selected from H, C1-8-alkyl and C3-8-cycloalkyl, or R6 and R7 are linked to form a cyclic group together with the nitrogen to which they are attached; and
R8 is C1-8-alkyl or C3-8-cycloalkyl.
The invention further relates to pharmaceutical compositions comprising compounds of formula (I), and the use of such compounds in the treatment of a disease selected from osteoporosis, Paget's disease, Chagas's disease, malaria, gingival diseases, hypercalaemia, metabolic bone disease, diseases involving matrix or cartilage degradation, and bone cancer disorders such as bone metastases and associated pain.
本发明涉及公式(I)的化合物及其药学上可接受的盐,其中:X为CH或N;R1和R2中的一个为H,另一个选择自OR6、SR6、NR6R7、N3、Me、Et、CF3、SOR8和SO2R8;R3选择自叔丁基甲基、异丙基甲基、仲丁基、叔丁基、环戊基和环己基;R4为可选择性取代的C1-8烷基或可选择性取代的C3-8环烷基;R6和R7各自独立地选择自H、C1-8烷基和C3-8环烷基,或R6和R7与它们所附着的氮一起形成一个环状基团;R8为C1-8烷基或C3-8环烷基。本发明还涉及包含公式(I)化合物的药物组合物,以及在治疗骨质疏松症、帕盖特病、查加斯病、疟疾、牙龈疾病、高钙血症、代谢性骨病、涉及基质或软骨降解的疾病以及骨癌疾病如骨转移和相关疼痛中使用这种化合物的用途。
