Development of a brain-penetrant G9a methylase inhibitor to target Alzheimer's disease-associated proteopathology

7 months 2 weeks ago
Current Aβ-targeting therapeutics for Alzheimer's disease (AD) only slow cognitive decline due to poor understanding of AD pathogenesis. Here we describe a mechanism of AD pathogenesis in which the histone methyltransferase G9a noncanonically regulates translation of hippocampal proteins associated with AD pathology. Correspondingly, we developed a brain-penetrant inhibitor of G9a, MS1262, which restored both age-related learning & memory and noncognitive functions in multiple AD mouse models....

Revealing the location and dynamics of a concealed binding site in the dopamine transporter

7 months 2 weeks ago
The dopamine transporter (DAT) is linked to neuropsychiatric disorders including ADHD, Parkinson's disease, and substance use disorders. Accordingly, DAT is the target of illicit drugs and clinically important medicines. However, the number and function of ligand binding sites in DAT is enigmatic due to conflicting data from available structures and molecular pharmacology. Herein, we design force sensors with DAT ligands and measure their interaction forces with wild-type and mutated DATs, from...
