Substituted isoxazolylthiophene compounds represented by general formula (I) or salts thereof, wherein R1 and R2 represents each C1-5 alkyl; R3 represents cyano or CONR5R6 (wherein R5 and R6 represent each hydrogen or C1-10 alkyl); R4 represents C1-5 alkyl or phenyl; and n is an integer of from 0 to 2. Because of specifically potentiating the functions of cell differentiation inducing factors occurring in vivo, these compounds are useful in treating or preventing various bone diseases or nervous diseases.
由通式(I)代表的取代
异噁唑基
噻吩化合物或其盐类,其中 R1 和 R2 分别代表 C1-5 烷基;R3 代表
氰基或 CONR5R6(其中 R5 和 R6 分别代表氢或 C1-10 烷基);R4 代表 C1-5 烷基或苯基;n 为 0 至 2 的整数。 由于能特异性地增强体内细胞分化诱导因子的功能,这些化合物可用于治疗或预防各种骨病或神经疾病。
