  A Focused Library of Psychotropic Analogues with Neuroprotective and Neuroregenerative Potential

  摘要：

  Overcoming the lack of effective treatments and the continuous clinical trial failures in neurodegenerative drug discovery might require a shift from the prevailing paradigm targeting pathogenesis to the one targeting simultaneously neuroprotection and neuroregeneration. In the studies reported herein, we sought to identify small molecules that might exert neuroprotective and neuroregenerative potential as tools against neurodegenerative diseases. In doing so, we started from the reported neuroprotective/neuroregenerative mechanisms of psychotropic drugs featuring a tricyclic alkylamine scaffold. Thus, we designed a focused-chemical library of 36 entries aimed at exploring the structural requirements for efficient neuroprotective/neuroregenerative cellular activity, without the manifestation of toxicity. To this aim, we developed a synthetic protocol, which overcame the limited applicability of previously reported procedures. Next, we evaluated the synthesized compounds through a phenotypic screening pipeline, based on primary neuronal systems. Phenothiazine 2Bc showed improved neuroregenerative and neuroprotective properties with respect to reference drug desipramine (2Aa). Importantly, we have also shown that 2Bc outperformed currently available drugs in cell models of Alzheimer's and Parkinson's diseases and attenuates microglial activation by reducing iNOS expression.

  an effective therapy is urgently needed. We followed the so-called “multitarget directed ligand” approach and designed 36 novel tacrine-phenothiazine heterodimers which were in vitro evaluated for their anticholinesterase properties. The assessment of the structure–activity relationships of such derivatives highlighted compound 1dC as a potent and selective acetylcholinesterase inhibitor with IC50

  自2002年以来，没有针对阿尔茨海默氏病的临床候选药物上市。因此，迫切需要一种有效的治疗方法。我们遵循所谓的“多靶标定向配体”方法，设计了36种新型他克林-吩噻嗪异二聚体，并对其体外抗胆碱酯酶特性进行了评估。对这类衍生物的构效关系的评估突出了化合物1dC作为有效的选择性乙酰胆碱酯酶抑制剂，IC 50 = 8 nM，1aA作为有效的丁酰胆碱酯酶抑制剂，IC 50 = 15 nM。选定的杂种，即1aC，1bC，1cC，1dC和2dC表现出对τ （306-336）肽聚集的显着抑制活性，抑制百分比范围为50.5至62.1％。同样，1dC和2dC具有抑制自诱导的Aβ1–42聚集的显着能力。尽管如此，体外研究显示对HepG2细胞和小脑颗粒神经元具有细胞毒性。当以14 mg / kg（ip）对小鼠施用1dC时，未观察到病理生理异常。如体外和体内模型所示，1dC还能够渗透到CNS中。最大大脑浓度接近IC乙
