GGTI-2154 hydrochloride is a potent and selective inhibitor geranylgeranyltransferase I (GGTase I), with an IC50 of 21 nM. GGTI-2154 hydrochloride shows more than 200-fold selectivity for GGTase I over FTase (IC50=5600 nM). GGTI-2154 hydrochloride can be used for the research of cancer[1][2]. | [in vivo]
GGTI-2154 (100 mg/kg/day; s.c. for 14 days) induces breast tumor regression in MMTV-ν-Ha-Ras transgenic mice[2].
GGTI-2154 (50 mg/kg/day; i.p. for 50 day) inhibits A-549 tumor growth in nude mice by 60%[1]. | Animal Model: | MMTV-v-Ha-ras transgenic mice bearing mammary carcinoma[2] | | Dosage: | 100 mg/kg/day | | Administration: | S.c. with osmotic mini-pumps for 14 days | | Result: | Halted the tumors aggressive growth.
Resulted in rapid tumor regression within 3 days of initiation of drug treatment.
