    • The present invention provides compositions and methods for differentiating and transdifferentiating mammalian cells into cells of an osteoblast lineage, using compounds of the following formula: wherein R4 is a functional group including, for example, C1-4alkyl, C3-8cycloalkyl, hydroxyl-C1-4alkyl, aryl-C0-3alkyl, substituted with 0-2 R4a groups, and heterocyclo-C0-2alkyl, optionally substituted with C1-4alkyl; R5 is hydrogen and R6 is a functional group including, for example, halogen, C1-4alkyl, —C(O)—C1-4alkyl, —SO2—N(R2b R2b), halo—C1-4alkyl, —O-aryl and —N(R7 R8), or when R5 and R6 are on adjacent ring atoms they are optionally taken together to form —O—(CH2)1-2—O—; and all pharmaceutically acceptable salts and hydrates thereof.
    • 本发明提供了使用下式化合物将哺乳动物细胞分化和转分化成成骨细胞谱系细胞的组合物和方法:其中R 4是包括例如C 1 -C 6烷基的官能团, 1-4个碳原子的烷基,C 3-8环烷基,羟基-C 1-4烷基,芳基-C 0-3-3烷基, 被0-2个R 4a取代的烷基和任选被C 1-4烷基取代的杂环-C 0-2-2烷基; R 5是氢,R 6是官能团,包括例如卤素,C 1-4烷基,-C(O) -C 1-4烷基,-SO 2 -N(R 2b,R 2b),卤代-C 1-4芳烷基,-O-芳基和-N(R 7 R 8),或当R 5 O >和R 6'在相邻的环原子上,它们任选地一起形成-O-(CH 2)2 - N 2 -O- ; 及其所有药学上可接受的盐和水合物。
