Deltarasin is a small molecule inhibitor of PDE6D that binds in the farnesyl-binding pocket of the enzyme and prevents interaction with KRAS4B and other farnesylated proteins (Zimmerman et al, 2013). PDE6D inhibition results in RAS protein mislocalization and reduces cellular proliferation and increase cell death in KRAS-dependent pancreatic cell lines (Zimmerman et al, 2013; reviewed in Shimansu et al, 2017). Other farnesyl-pocket binding small molecule inhibitors are also under development (Papke et al, 2016).
