L-778123 is a dual inhibitor of Farnesyl Protein Transferase (FPTase) and Geranylgeranyl Protein Transferase type-I (GGPTase-I), which can completely inhibit Ki-Ras prenylation. L-778123 has been used in phase I clinical trials to determine its effectiveness in treating patients with recurrent or refractory solid tumors. L-778123 was also studied in combination with paclitaxel to determine efficacy as a treatment for both recurrent or refractory solid tumors, and lymphomas.

L-778,123 is an inhibitor of both Farnesyl:protein transferase (FPTase) and geranylgeranyl:protein transferase type-I (GGPTase-I). Using immunoblotting methods that distinguish between prenylated and unprenylated forms of a protein based on differences in their electrophoretic mobility, it was confirmed the activity of L-778,123 as a dual prenyltransferase inhibitor (DPI) in PSN-1 human pancreatic tumor cells. L-778,123 inhibited the prenylation of the FPTase substrate, HDJ2 (EC50 = 92 nm), the GGPTase-I substrate, Rap1A (EC50=6.760 nM), and because it was a DPI, also blocks the prenylation of Ki-Ras (EC50 = 6.300 nM).
