We report on dual, light-responsive and redox-active foldamers that demonstrate reversible and robust stimuli-induced behaviour. Herein, UV/Vis, H NMR and circular dichroism (CD) spectroscopy and cyclic voltammetry have been used to establish the reversibility and highly robust nature of the light- and redox-driven behaviour of these new foldamers with minimal levels of fatigue observed even upon multiple cyclic treatments with irradiative/non-irradiative and oxidative/reductive conditions. This proof-of-concept work paves the way towards the creation of novel stimuli-responsive foldamers of increasing sophistication capable of demonstrating reversible and robust responses to multiple distinct stimuli.

Background: Dysregulated GABA/somatostatin (SST) signaling has been implicated in psychiatric and neurodegenerative disorders. The inhibition of excitatory neurons by SST+ interneurons, particularly through α5-containing GABAA receptors (α5-GABAAR), plays a crucial role in mitigating cognitive functions. Previous research demonstrated that an α5-positive allosteric modulator (α5-PAM) mitigates working memory deficits and reverses neuronal atrophy in aged mice.

Background: The hyperphosphorylation, mislocalization, and aggregation of the microtubule associated protein Tau (MAPT) is a driving force in tauopathies, a group of progressive, neurodegenerative disorders. These pathogenic intracellular aggregates, known as neurofibrillary tangles (NFTs), are a hallmark in several diseases such as frontotemporal dementia, progressive supranuclear palsy, and Alzheimer's Disease. While anti-Tau immunotherapies emphasize the clearance of extracellular Tau aggregates, they do not address the intracellular accumulation of NFTs.

Background: Individuals with type 2 diabetes mellitus (T2DM) face an increased risk of dementia. Recent discoveries indicate that SGLT2 inhibitors, a newer class of anti-diabetic medication, exhibit beneficial metabolic effects beyond glucose control, offering a potential avenue for mitigating the risk of Alzheimer's disease (AD). However, limited evidence exists regarding whether the use of SGLT2 inhibitors effectively reduces the risk of AD.

Cerebral beta-amyloid accumulation is the key initiator of Alzheimer's disease (AD) pathology. Most familial early-onset AD mutations in the APP, PSEN1/2 genes increase the ratio of Abeta42:Abeta40, which drives beta-amyloid accumulation in the brain. In 2001, the late Steve Wagner, Maria Kounnas, and I directed an agnostic high-throughput screen for compounds that would reverse the Abeta42:Abeta40, ratio, and discovered the first non-NSAID (second generation) gamma secretase modulators (GSM) at TorreyPines Therapeutics.

Background: Responses to individualized music in people living with dementia can be indicated by both verbal and non-verbal cues. Evidence suggests that elevated pupil dilation responses to familiar vs. unfamiliar music are preserved in people living with typical Alzheimer's disease (tAD), and to an extent in people with its atypical 'visual' variant (Posterior Cortical Atrophy; PCA) (Brotherhood et al.
