Hras depends for activity upon farnesylation, which can be blocked by farnesylation inhibitors, including the compound fti277. Although the prenylation of hras was also sensitive to fti277, complete inhibition of hras processing even at high concentrations of fti277 andor ggti298 was never achieved. Additionally, fti277 increases postirradiation apoptosis and enhances the radiation sensitivity of hras transformed rat embryo cells. Dive into the research topics of ras caax peptidomimetic fti277 selectively blocks oncogenic ras signaling by inducing cytoplasmic accumulation of inactive rasraf complexes.
