GGTI298

CAS No. : 180977-44-0

MCE 站：GGTI298

产品活性：GGTI298 是有效的 GGTase I 抑制剂，能够抑制 geranylgeranylated Rap1A 的过程，对 farnesylated Ha-Ras 的过程也有一定影响，在体内，IC₅₀ 值分别为 3 和 > 20 μM。

研究领域：GPCR/G Protein  |  Apoptosis

作用靶点：Ras  |  Apoptosis

In Vitro: Both RhoA inhibitor (GGTI298) and ROCK inhibitor (H1152) significantly reduce cAMP agonist-stimulated IK(ap), whereas the latter additionally reduces colocalization of KCNN4c with the apical membrane marker wheat germ agglutinin in T84WT cells. Knockdown of DR4 abolishes NF-κB activation, leading to sensitization of DR5-dependent apoptosis induced by the combination of GGTI298 and TRAIL. GGTI298/TRAIL activates NF-κB and inhibits Akt. knockdown of DR5, preventes 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.

In Vivo: The vivo mouse ileal loop experiments show fluid accumulation is reduced in a dose-dependent manner by TRAM-34, GGTI298, or H1152 when injected together with cholera toxin into the loop.
