One of the main symptoms in degenerative diseases is death of neuronal cell followed by the loss of neuronal pathways. In neuronal cultures, neurite outgrowths are cell sprouts capable of transforming into either axons or dendrites, to further form functional neuronal synaptic connections. Such connections have an important role in brain cognition, neuronal plasticity, neuronal survival, and regeneration. Therefore, drugs that stimulate neurite outgrowth may be found beneficial in ameliorating neural degeneration. Here, we establish the existence of a unique family of methylene-cycloalkylacetate-based molecules (MCAs) that interface with neuronal cell properties and operate as acceptable pharmacophores for a novel neurotropic (neurite outgrowth inducing) lead compounds. Using an established PC12 cell bioassay, we investigated the neurotropic effect of methylene-cycloalkylacetate compounds by comparison to NGF, a known neurotropic factor. Micrographs of the cells were collected by using a light microscope camera, and digitized photographs were analyzed for compound-induced neurotropic activity using an NIH image protocol. The results indicate that the alkene element, integrated within the cycloalkylacetate core, is indispensable for neurotropic activity. The discovered lead compounds need further mechanistic investigation and may be improved toward development of a neurotropic drug.

亚甲基-环烷基乙酸酯(MCA)支架基化合物作为新型神经营养剂。

退行性疾病的主要症状之一是神经元细胞死亡,其次是神经元途径的丧失。在神经元培养物中,神经突产物是能够转化为轴突或树突以进一步形成功能性神经元突触连接的细胞新芽。这种联系在大脑认知,神经元可塑性,神经元存活和再生中具有重要作用。因此,可以发现刺激神经突生长的药物对于改善神经变性是有益的。在这里,我们建立了一个独特的基于亚甲基环烷基乙酸酯的分子家族(MCA),该分子与神经元细胞特性相接,并作为新型神经质(神经突生长诱导)先导化合物的可接受的药效团。使用已建立的PC12细胞生物测定法,通过与已知的神经营养因子NGF进行比较,我们研究了亚甲基-环烷基乙酸酯化合物的神经营养作用。通过使用光学显微镜照相机收集细胞的显微照片,并使用NIH图像方案分析数字化照片的化合物诱导的神经活性。结果表明,整合在环乙酸烷基酯核心中的烯烃元素对于神经活性是必不可少的。发现的先导化合物需要进一步的机理研究,并且可能会朝着发展神经性药物的方向发展。然后使用NIH图像协议分析数字化照片的化合物诱导的神经活性。结果表明,整合在环乙酸烷基酯核心中的烯烃元素对于神经活性是必不可少的。发现的先导化合物需要进一步的机理研究,并且可能会朝着发展神经性药物的方向发展。然后使用NIH图像协议分析数字化照片的化合物诱导的神经活性。结果表明,整合在环乙酸烷基酯核心中的烯烃元素对于神经活性是必不可少的。发现的先导化合物需要进一步的机理研究,并且可能会朝着发展神经性药物的方向发展。
