, A, X, a, x and n is as defined in the specification. Substituted piperidine compounds of structure I may permeate or penetrate across a nerve cell membrane into the interior of a nerve cell, may inhibit intracellular Rho kinase enzyme found in nerve cells in mammals, and may find utility in repair of damaged nerves in the central and peripheral nervous system of such mammals. These compounds may induce the regeneration or growth of neurites in mammalian nerve cells and may thereby induce regeneration of damaged or diseased nerve tissue. These compounds also find additional utility as antagonists of the enzyme Rho kinase in treatment of disease states in which Rho kinase is implicated. Pharmaceutical compositions containing these substituted piperidine compounds may be useful to promote neurite growth and in the treatment of diseases in which Rho kinase inhibition is indicated.
提供了由结构式I表示的取代哌啶化合物,其中R1a、R1b、R1c、R1d、R1e、R1f、R1g、R1h、R2、R2A、R3、R4、A、X、a、x和n的定义如规范中所述。结构式I的取代哌啶化合物可以渗透或穿过神经细胞膜进入神经细胞内部,可以抑制哺乳动物神经细胞中发现的细胞内Rho激酶酶,并可用于修复哺乳动物中心和周围神经系统中的受损神经。这些化合物可以诱导哺乳动物神经细胞的轴突再生或生长,从而诱导受损或患病的神经组织再生。这些化合物还可作为Rho激酶酶拮抗剂,在治疗涉及Rho激酶酶的疾病状态中发现其他用途。含有这些取代哌啶化合物的制药组合物可用于促进神经轴突生长,并用于治疗需要Rho激酶抑制的疾病。
