GGTI298 Trifluoroacetate is a CAAZ peptidomimetic geranylgeranyltransferase I (GGTase I) inhibitor, which can inhibit Rap1A with IC₅₀ of 3 μM; little effect on Ha-Ras with IC₅₀ of >20 μM.

IC50: 3 μM (Rap1A, in vivo), > 20 μM (Ha-Ras, in vivo)^[3]

RhoA inhibitor (GGTI298 Trifluoroacetate) significantly reduces cAMP agonist-stimulated apical K+ conductance^[1]. Knockdown of DR4 abolishes NF-κB activation, leading to sensitization of DR5-dependent apoptosis induced by the combination of GGTI298 Trifluoroacetate and TRAIL. GGTI298 Trifluoroacetate/TRAIL activates NF-κB and inhibits Akt. Knockdown of DR5, prevents GGTI298/TRAIL-induced IκBα and p-Akt reduction, suggesting that DR5 mediates reduction of IκBα and p-Akt induced by GGTI298/TRAIL. In contrast, DR4 knockdown further facilitates GGTI298/TRAIL-induced p-Akt reduction^[2].

The ileal loop experiment is performed in 6-8-week-old mice by a modifing rabbit ileal loop assay. Following gut sterilization, the animals are kept fasted for 24 h prior to surgery and fed only water ad libitum. Anesthesia is induced by a mixture of ketamine (35 mg/kg of body weight) and xylazine (5 mg/kg of body weight). A laparotomy is performed, and the experimental loops of 5-cm length are constricted at the terminal ileum by tying with non-absorbable silk. The following fluids are instilled in each loop by means of a tuberculin syringe fitting with a disposable needle through the ligated end of the loop: pure CT (1 μg; positive control), saline (negative control), CT (1 μg)+TRAM-34 (different concentrations in μM), CT (1 μg)+ H1152 (1 μM), and CT (1 μg)+GGTI298 Trifluoroacetate (different concentrations in μM), a specific inhibitor of Rap1A. The intestine is returned to the peritoneum, and the mice are sutured and returned to their cages. After 6 h, these animals are sacrificed by cervical dislocation, and the loops are excised^[1].
