    • Neurotrophin binding to its specific receptors Trk A and p75 leads to the activation of multiple signalling cascades, culminating in neuroprotective and regenerative effects, including neuronal survival and neurite outgrowth. Neurotrophic factors have been used for the treatment of several neurodegenerative diseases. However, their use is limited by their inability to cross the blood-brain barrier, their short half life and their side effects. Small molecule neurotrophin mimetics may be beneficial in treating a number of neurodegenerative disorders. The present invention shows the capacity of nerve growth factor agonist molecules of Formulae I-IV, as defined in the specification, to induce differentiation in PC 12 cells, promote survival in RN22 cells and activate Trk A, IkBa and SAPK/JNK phosphorylation to various extents in both cell lines. In addition these molecules were able to ameliorate acute experimental autoimmune encephalomyelitis (EAE), a multiple sclerosis (MS) animal model, inhibiting brain inflammation and reducing brain damage. We also observed suppression in the production of pro-inflammatory genes like the inducible nitric oxide synthase. These small molecules with NGF agonist activity may be beneficial for MS and other neurodegenerative diseases due to its neuroprotective and immunomodulatory properties.
    • 神经营养因子与其特异性受体Trk A和p75结合导致多个信号级联的激活,最终导致神经保护和再生效应,包括神经元存活和神经突生长。 神经营养因子已被用于治疗几种神经变性疾病。 然而,它们的使用受到无法跨越血脑屏障,半衰期短及其副作用的限制。 小分子神经营养因子模拟物可能有益于治疗许多神经变性疾病。 本发明显示了本说明书中定义的式I-IV的神经生长因子激动剂分子在PC12细胞中诱导分化的能力,促进RN22细胞中的存活并激活TrkA,IkBa和SAPK / JNK磷酸化到各种 两个细胞系的范围。 此外,这些分子能够改善急性实验性自身免疫性脑脊髓炎(EAE),多发性硬化(MS)动物模型,抑制脑部炎症并减少脑损伤。 我们还观察到产生促炎基因如诱导型一氧化氮合酶的抑制。 这些具有NGF激动剂活性的小分子由于其神经保护和免疫调节特性而可能对MS和其它神经变性疾病有益。
