Obesity is a multifactorial disease in which environmental conditions and genetic factors play an important pathogenic role [1]. Interestingly, some of these obesogenic environmental and genetic conditions are shared with neurodegenerative diseases (NDD). The common biological mechanisms involved in obesity and NDD are insulin resistance, pro-inflammatory cytokines, and oxidative damage, in turn leading to cognitive dysfunction or cell death. In this aspect, a poly-pharmacolog...

We have already reported that synthetic analogs of 3-iodothyronamine (T1AM), a naturally occurring thyroid hormone derivative, share a pleiotropic activity with the endogenous parent compound, including autophagic flux promotion (ATG), neuroprotection, and metabolic reprogramming. Our study aimed to determine whether the T1AM lead analog SG2 and its derivatives SG22 and SG23, developed as prodrugs of SG2, can protect human glioblastoma U87 MG cells from the toxic effects induc...

Microglial dysfunction is one of the hallmarks and leading causes of common neurodegenerative diseases (NDD), including Alzheimer’s disease (AD), Parkinson’s disease (AD), and amyotrophic lateral sclerosis (ALS). All these pathologies are characterized by aberrant aggregation of disease-causing proteins in the brain, which can directly activate microglia, trigger microglia-mediated neuroinflammation, and increase oxidative stress. The availability of cell-permeable i...

The endogenous thyroid hormone derivative 3-iodothyronamine (T1AM), and its metabolite 3-iodothyroacetic acid (TA1) are known to stimulate learning and induce hyperalgesia in mice. Recently, it has been demonstrated that exogenous T1AM is able to rescue synaptic impairment after transient ischemia in the entorhinal cortex (EC), a brain area crucially involved in learning and memory, and early affected during Alzheimer’s disease. However, i...
