alkyl, or unsubstituted or substituted heterocyclyl, a process for the preparation of such a compound, a pharmaceutical composition containing such a compound and the use of the compound or composition in medicine. Particular indole compounds are selective for mammalian osteoclasts, acting to selectively inhibit their bone resorbing activity. These compounds are therefore considered to be particularly useful for the treatment and/or prophylaxis of diseases associated with loss of bone mass, such as osteoporosis and related osteopenic diseases, Paget's disease, hyperparathyroidism and related diseases. These compounds are also considered to possess antitumour activity, antiviral activity (for example against Semliki Forest, Vesicular Stomatitis, Newcastle Disease, Influenza A and B, HIV viruses), antiulcer activity (for example the compounds may be useful for the treatment of chronic gastritis and peptic ulcer induced by
Helicobacter pylori
), immunosuppressant activity, antilipidemic activity, antiatherosclerotic activity and to be useful for the treatment of AIDS and Alzheimer's disease. Furthermore, these compounds are also considered useful in inhibiting angiogenesis, i.e., the formation of new blood vessels which is observed in various types of pathological conditions (angiogenic diseases) such as rheumatoid arthritis, diabetic retinopathy, psoriasis and solid tumours.
化合物公式(I)或其盐或其溶剂化物,其中:R1和R2各自独立表示C1-6烷氧基或卤素基;R3和R4各自独立表示氢、C1-6烷氧基、芳基C1-6烷氧基、羟基、羧基C1-6烷氧基、羟基C1-6烷氧基、二羟基C1-6烷氧基、单-和双-(C1-6烷基)氨基C1-6烷氧基或氨基C1-6烷氧基,R5表示-NRsRt,其中Rs和Rt各自独立表示氢、未取代或取代C1-6烷基或未取代或取代杂环基,制备此类化合物的方法,含有此类化合物的制药组合物以及该化合物或组合物在医学上的应用。特定的吲哚化合物对哺乳动物破骨细胞选择性作用,具有选择性地抑制它们的骨吸收活性。因此,认为这些化合物特别适用于治疗和/或预防与骨量丢失相关的疾病,如骨质疏松症和相关的骨质疏松病、帕吉特病、甲状旁腺功能亢进症和相关疾病。认为这些化合物还具有抗肿瘤活性、抗病毒活性(例如对森林脑炎、口疮病毒、新城疫、甲型和乙型流感病毒、HIV病毒等),抗溃疡活性(例如这些化合物可以用于治疗由幽门螺杆菌引起的慢性胃炎和消化性溃疡),免疫抑制活性、抗脂质血症活性、抗动脉粥样硬化活性,并且对治疗艾滋病和阿尔茨海默病有用。此外,认为这些化合物还有抑制血管生成的作用,即在各种病理情况下(血管生成性疾病),如类风湿性关节炎、糖尿病视网膜病变、银屑病和实体瘤中观察到的新血管形成。
