Background:
GGTI 2133 is a peptidomimetic inhibitor of geranylgeranyl transferase type I (GGTase I; IC50= 38 nM).1It is 140-fold selective for GGTase I over farnesyltransferase (IC50= 5,400 nM).In vitro, it inhibits geranylgeranylation of RAP1A (IC50= 10 ?M) without inhibiting farnesylation of H-Ras (IC50= >30 ?M). It also inhibits cell growth and decreases migration and invasion of oral squamous cell carcinoma (OSSC) cells to 75, 45, and 27% of control values, respectively.2GGTI 2133 (5 mg/kg per day, i.p.) prevents ovalbumin-induced eosinophil infiltration into airways in a mouse model of allergic bronchial asthma but does not prevent an increase in chemokines.3It also blocks naloxone-induced contraction of ileum isolated from rats with morphine withdrawal syndrome and dose-dependently decreases withdrawal severityin vivo(ED50= 0.076 mg/kg).4
