Article
Full-text available
In excitable cells, mitochondria play a key role in the regulation of the cytosolic Ca2+ levels. A dysregulation of the mitochondrial Ca2+ buffering machinery derives in serious pathologies, where neurodegenerative diseases highlight. Since the mitochondrial Na+/Ca2+ exchanger (NCLX) is the principal efflux pathway of Ca2+ to the cytosol, drugs cap...
Article
Multitarget-directed ligands (MTDLs) are considered a promising therapeutic strategy to address the multifactorial nature of Alzheimer's disease (AD). Novel MTDLs have been designed as inhibitors of human acetylcholinesterases/butyrylcholinesterases, monoamine oxidase A/B, and glycogen synthase kinase 3β and as calcium channel antagonists via the B...

N-Propargylamines are useful synthetic scaffolds for the synthesis of bioactive molecules, and in addition, they possess important pharmacological activities. We obtained several neuroprotective molecules, chiral 1,2-amino alcohols and 1,2-diamines, able to reduce by almost 70% the rotenone and oligomycin A-induced damage in SH-SY5Y cells. Furtherm...
Article
We herein report the design, synthesis, and functional impact of an okadaic acid (OA) small analogue, ITH12680, which restores the activity of phosphoprotein phosphatase 2A (PP2A), whose deficient activity has been implicated in nicotine-mediated tumor progression and chemoresistance in non-small cell lung cancer (NSCLC). For its design, we paid at...
Article
New tritarget small molecules combining Ca2+ channels blockade, cholinesterase and H3 receptor inhibition were obtained by multicomponent synthesis. Compound 3p has been identified as a very promising lead, showing good Ca2+ channels blockade activity (IC50 = 21 ± 1 μM), potent affinity against hH3R (Ki = 565 ± 62 nM), a moderate, but selective hBu...
Article
Current healthcare has significantly increased the average life expectancy, leading to a consequently greater incidence of age-related diseases, such as Alzheimer's disease. Following a multitarget approach, in this paper a series of polycyclic maleimide-based derivatives were designed and synthesized aimed at simultaneously modulate neuronal calci...
Article
We report the synthesis and pharmacological evaluation of new 3-aminomethylindoles derivatives with neuroprotective properties designed to present multi-target activity centered on reducing the neuronal Ca²⁺ overload and preventing phosphatase 2A (PP2A) inhibition, which are two important early physiophathological events observed in neurodegenerati...
Article
Melatonin is an endogenous hormone produced by the pineal gland as well as many other tissues and organs. The natural decline in melatonin levels with aging strongly contributes to the development of neurodegenerative disorders. Neurodegenerative diseases share common mechanisms of toxicity such as proteinopathy, mitochondrial dysfunction, metal dy...
Article
Following the premises of the multitarget-directed ligands approach for the drug R&D against neurodegenerative diseases, where Alzheimer's disease (AD) outstands, we have synthesized and evaluated analogues of the gramine derivative ITH12657 (1-benzyl-5-methyl-3-(piperidin-1-ylmethyl-1H-indole, 2), which had shown important neuroprotective properti...
Article
We describe the synthesis of gramine derivatives and their pharmacological evaluation as multipotent drugs for the treatment of Alzheimer's disease. An innovative multitarget approach is presented, targeting both voltage-gated Ca2+ channels, classically studied for neurodegenerative diseases, and Ser/Thr phosphatases, which have been marginally aim...

Article
Introduction: The role played by phosphoprotein phosphatases (PPP) enzymes makes them of interest as therapeutic targets to treat pathologies including neurodegenerative diseases, cancer and autoimmune diseases, but also liable to cause severe side effects. This fact has hindered the study of PPP ligands as potential drugs. Fortunately, recent adv...
Article
Mitochondria regulate cellular Ca2+ oscillations, taking up Ca2+ through its uniporter and releasing it through the mitochondrial sodium/calcium exchanger. The role of mitochondria in the regulation of Ca2+ cycle has received much attention recently, as it is a central stage in neuronal survival and death processes. Over the last decades, the 4,1-b...
