https://www.selleckchem.com/products/U0126.html The ligand-sensing transcription factor tailless homologue (TLX, NR2E1) is an essential regulator of neuronal stem cell homeostasis with appealing therapeutic potential in neurodegenerative diseases and central nervous system tumors. However, knowledge on TLX ligands is scarce, providing an obstacle to target validation and medicinal chemistry. To discover TLX ligands, we have profiled a drug fragment collection for TLX modulation and identified several structurally diverse agonists and inverse agonists of the nuclear receptor. Propranolol evolved as the strongest TLX agonist and promoted TLX-regulated gene expression in human glioblastoma cells. Structure-activity relationship elucidation of propranolol as a TLX ligand yielded a structurally related negative control compound. In functional cellular experiments, we observed an ability of propranolol to counteract glioblastoma cell proliferation and migration, while the negative control had no effect. Our results provide a collection of TLX modulators as initial chemical tools and set of lead compounds and support therapeutic potential of TLX modulation in glioblastoma.Tau aggregation is believed to have a strong association with the level of cognitive deficits in Alzheimer's disease (AD). Thus, optical brain imaging of tau aggregates has recently gained substantial attention as a promising tool for the early diagnosis of AD. However, selective imaging of tau aggregates is a major challenge due to sharing similar β-sheet structures with homologous Aβ fibrils. Herein, four quinoline-based fluorescent probes (Q-tau) were judiciously designed using the donor-acceptor architecture for selective imaging of tau aggregates. In particular, probe Q-tau 4 exhibited a strong intramolecular charge transfer and favorable photophysical profile, such as a large Stokes' shift and fluorescence emission wavelength of 630 nm in the presence of tau aggregates. The probe also displayed a "t
