is independently a biphenyl, phenanthryl, fluorenyl, or carbazolyl, and is optionally substituted; R
alk
is independently a C
2-10
alkylene group, and is optionally substituted; —OR

The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit osteoclast survival, formation, and/or activity, and to inhibit conditions mediated by osteoclasts and/or characterised by bone resorption, in the treatment of bone disorders such as osteoporosis, rheumatoid arthritis, cancer associated bone disease, Paget's disease, aseptic loosening of prosthetic implants, and the like; and/or in the treatment of conditions associated with inflammation or activation of the immune system.
本发明涉及某些酮和还原酮及其衍生物,其中包括抑制破骨细胞的存活、形成和/或活性;和/或抑制骨吸收的化合物,更具体地说,是以下式子的化合物:(1)(2)
其中:Ar1独立地是联苯基,菲基,芴基或咔唑基,且可以被取代;Ralk独立地是C2-10烷基,且可以被取代;-ORO,如果存在,则独立地是-OH或-ORK;-ORK,如果存在,则独立地选自:-O-RK1;-O-C(═O)-RK2;-O-C(═O)-ORK3;-O-S(═O)2ORK4;Q独立地是-OH或-OROT;其中:-OROT,如果存在,则独立地选自:-O-RE1;-O-C(═O)-RE2;-O-C(═O)-O-RE3;-O-C(═O)-O-SO3RE4;-O-C(═O)-O-(CH2)n-COORE5;-O-C(═O)-(CH2)n-NRN1RN2;-O-C(═O)-(CH2)n-NH-C(═O)RE6;-O-C(═O)-(CH2)n-C(═O)-NRN3RN4;-O-P(═O)(ORE7)(ORE8);-O-RPA;如果存在RPA,则是包含膦酸基的有机基团;但前提是如果-OROT是-O-RE1,则RE1不是取代有磺酰基的苯基;以及其药学上可接受的盐、溶剂化合物、酰胺、酯、醚、化学保护形式或前药。本发明还涉及包含这种化合物的制药组合物,以及这种化合物和组合物的使用,无论是在体内还是体外,以抑制破骨细胞的存活、形成和/或活性,并抑制由破骨细胞介导和/或特征为骨吸收的疾病,如骨质疏松症、类风湿性关节炎、癌症相关骨病、帕吉特病、假体松动等;和/或用于治疗与炎症或免疫系统激活相关的疾病。
