    Abstract: Provided herein are, inter alia, amphiphilic thiol compounds and methods of using the same for the purpose of depalmitoylating proteins in cellular membranes (e.g., plasma membranes). The compounds provided herein include an amphiphilic tail, which enables them to associate with a cellular membrane and depalmitoylate (cleave native S-palmitoyl groups from) a protein in said membrane by native chemical ligation thereby triggering the protein's release from the plasma membrane. The compounds (amphiphilic thiol compounds of formula (I), (II), (III)) are, inter alia , useful for the treatment of diseases caused or associated with aberrant depalmitoylation of certain proteins (e.g., HRas, EGFR).
