Small Molecule Modulator of the mTORC2 Pathway Discovered from a DEL Library Designed to Bind to Pleckstrin Homology Domains.

ABSTRACT: Pleckstrin homology (PH) domains are structural motifs critical for cellular processes, such as signal transduction and cytoskeletal organization. Due to their involvement in various diseases, PH domains are promising therapeutic targets, yet their highly charged and hydrophobic binding sites are not ideal for traditional small drugs. In this study, we designed a DNA-encoded library (DEL) mimicking phospholipids to identify novel modulators targeting PH domains with uncharted chemical properties. Screening against several PH domains led to the discovery of 2DII, a small molecule that selectively binds to mSin1^PH. This compound can modulate mTORC2 activity by impairing mTORC2's membrane interactions, resulting in reduced AKT1 phosphorylation. A micromapping via Dexter energy tran
