CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe multifactorial nature of Alzheimer’s disease (AD) offers us a textbook example where parental compounds, mostly marketed, are modified with the aim of improving and/or conferring two or even more biological activities to contrast or less frequently revert the disease’s symptoms. This is the case of tacrine and its dimeric derivative bis(7)-tacrine which, for instance, paved the way for the development of a broad collection of very interesting homo- and heterodimeric structures, conceived in light of the emerging multi-target approach for AD-related drug discovery. As a contribution to the topic, we report here the design, synthesis and biological evaluation of 12 compounds referable to bis(7)-tacrine. In addition to the cholinesterase activity, some of the selected compounds (7-9 and 12) were capable of inhibiting the non-enzymatic function of AChE and/or showed a remarkable activity against BACE 1. Thus, the present study outlines a series of newly synthesized molecules, structurally related to bis(7)-tacrine, endowed with extended biological profile in agreement with the emerging multi-target paradigm.

| Abstract: | The multifactorial nature of Alzheimer’s disease (AD) offers us a textbook example where parental compounds, mostly marketed, are modified with the aim of improving and/or conferring two or even more biological activities to contrast or less frequently revert the disease’s symptoms. This is the case of tacrine and its dimeric derivative bis(7)-tacrine which, for instance, paved the way for the development of a broad collection of very interesting homo- and heterodimeric structures, conceived in light of the emerging multi-target approach for AD-related drug discovery. As a contribution to the topic, we report here the design, synthesis and biological evaluation of 12 compounds referable to bis(7)-tacrine. In addition to the cholinesterase activity, some of the selected compounds (7-9 and 12) were capable of inhibiting the non-enzymatic function of AChE and/or showed a remarkable activity against BACE 1. Thus, the present study outlines a series of newly synthesized molecules, structurally related to bis(7)-tacrine, endowed with extended biological profile in agreement with the emerging multi-target paradigm. | |
