  • Compounds were selected based on either their ability to inhibit Ras/MAPK activity or to modulate ion channel function, mostly with the expectation of reducing neuronal excitability. As part of the “Ras/MAPK” targeting group, inhibitors of histone deacetylase (HDAC) and CDK4/6 were included since they have been demonstrated to improve viability in Drosophila models of other RASopathies (Das et al., 2021).
