FGTI-2734 mesylate 是 RAS C-末端法尼基转移酶 (FT) 和香叶烯基转移酶-1 (GGT) 抑制剂,对 FT 和 GGT 的IC50s 分别为 250 nM 和 520 nM。FGTI-2734 mesylate 可以阻断 KRAS 的膜定位,从而解决 KRAS 耐药性问题,并抑制突变的 KRAS 胰腺肿瘤。
生物活性 | FGTI-2734 mesylate is aRASC-terminal mimetic dualfarnesyl transferase(FT)andgeranylgeranyl transferase-1 (GGT)inhibitor withIC50s of 250 nM and 520 nM for FT and GGT, respectively. FGTI-2734 mesylate can prevent membrane localization of KRAS, hence solving KRAS resistance problem and thwarting mutant KRAS patient-derived pancreatic tumors[1]. |
IC50& Target | IC50: 250 nM (FT) and 520 nM (GGT)[1] |
体外研究 (In Vitro) | FGTI-2734 mesylate (1-30 μM; 72 hours) induces apoptosis in mutant KRAS-dependent, but not mutant KRAS- independent, human cancer cells[1]. FGTI-2734 mesylate (3-30 μM; 72 hours) inhibits both protein prenylation of HDJ2, RAP1A, KRAS and NRAS. FGTI-2734 inhibits KRAS membrane localization in RAS-transformed murine NIH3T3 cells and in mutant KRAS human cancer cells[1].
Apoptosis Analysis[1] Cell Line: | MiaPaCa2, L3.6pl, Calu6 cells | Concentration: | 1, 3, 10, 30 μM | Incubation Time: | 72 hours | Result: | Induced apoptosis in mutant KRAS-dependent human cancer cell lines |
Western Blot Analysis[1] Cell Line: | KRAS, HRAS, and NRAS-transformed NIH3T3 cells | Concentration: | 3, 10, 30 μM | Incubation Time: | 72 hours | Result: | Inhibited both protein prenylation of HDJ2, RAP1A, KRAS and NRAS. |
|
体内研究 (In Vivo) | FGTI-2734 mesylate (intraperitoneally; 100 mg/kg/day for 18 to 25 days) only inhibits tumor growth in mutant KRAS-dependent tumors but not in mutant KRAS-independent tumors[1].
Animal Model: | Male SCID-bg mice following injection of MiaPaCa2, L3.6pl, Calu6, A549, H460 and DLD1 cancer cells[1] | Dosage: | 100 mg/kg | Administration: | Intraperitoneally; daily; for 18 to 25 days | Result: | Inhibited tumor growth in mutant KRAS-dependent tumors. |
