HRas Selective Depalmitoylating Drugs

Tech ID: 30540 / UC Case 2020-033-0


HRas is a member of the Ras family of GTPases, which function as key regulatory proteins in cell differentiation, proliferation, and survival. Mutations in HRas are associated with several cancers, as well as Costello syndrome, a severe congenital disorder for which there is no cure. Therefore, there is significant interest in developing therapeutics which target HRas signaling. However, Ras proteins are challenging to target

Technology Description

Previously, researchers from UC San Diego have developed an NCL-based depalmitoylation strategy for the chemo-selective cleavage of S-palmitoyl groups in vivo (hyperlink: ).

Recently, the researchers designed a set of newly synthesized compounds that exhibit improved potency and selectivity toward the therapeutically relevant proteins HRas and NRas in live cells.



These new compounds illustrate a general roadmap for the design and synthesis of depalmitoylating compounds and has potential therapeutic applications for a number of diseases in which palmitoylation is dysregulated, such as cancer.
