| Hazard Information | Back Directory | [Description]
GGTI 2133 is a peptidomimetic inhibitor of geranylgeranyl transferase type I (GGTase I; IC50 = 38 nM). It is 140-fold selective for GGTase I over farnesyltransferase (IC50 = 5,400 nM). In vitro, it inhibits geranylgeranylation of RAP1A (IC50 = 10 μM) without inhibiting farnesylation of H-Ras (IC50 = >30 μM). 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. GGTI 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. It also blocks naloxone-induced contraction of ileum isolated from rats with morphine withdrawal syndrome and dose-dependently decreases withdrawal severity in vivo (ED50 = 0.076 mg/kg). | [Uses]
GGTI-2133 has been used
- To understand the role of geranylgeranyl transferase in the regulation of CXC chemokine production and neutrophil recruitment in the lung.
- To study the importance of geranylgeranylation in cell adhesion.
- To measure ligand-induced ADP-ribosylation factor 6 (Arf6) activation in breast cancer cells.
| [Biochem/physiol Actions]
GGTase I mediates prenylation to induce the oncogenic functions of the Ras and Rho proteins. Thus, GGTase I inhibitors can be utilized as effective anticancer drugs. They are also useful in treating inflammation, atherosclerosis, multiple sclerosis and other diseases. | [storage]
