|Description||GGTI-2418 is a highly potent, competitive, and selective geranylgeranyltransferase I (GGTase I) inhibitor. GGTI-2418 inhibits GGTase I and FTase activities with IC50s of 9.5 nM and 53 μM, respectively. GGTI-2418 also increases p27(Kip1) and induces significant regression of breast tumors.|
|IC50 & Target|
IC50: 9.5 nM (GGTase I), 53 μM (FTase)
|In Vitro||GGTI-2418 inhibits GGTase I and FTase activities with IC50s
of 9.5±2.0 nM and 53±11 μM, respectively, a 5,600-fold selectivity
toward inhibition of GGTase I versus FTase. GGTI-2418 demonstrates
competitive inhibition of GGTase I against the H-Ras-CVLL protein with a
Ki of 4.4±1.6 nM.|
GGTi-2418 (10-15 μM; 16 hours) treatment delocalizes FBXL2 and stabilizes IP3R3.
