Used primarily in biochemical research to study the role of isoprenylcysteine carboxyl methyltransferase (ICMT) in cellular processes. It is a potent inhibitor of ICMT, an enzyme involved in the post-translational modification of proteins, particularly Ras family proteins. By inhibiting ICMT, it helps researchers understand the enzyme's role in cancer development and progression, as Ras proteins are often mutated in various cancers. Additionally, it is utilized in studies exploring the potential of ICMT inhibition as a therapeutic strategy for Ras-driven cancers. Its application extends to investigating the broader implications of protein prenylation and methylation in cell signaling and function.
