| Hazard Information | Back Directory | [Uses]
RPI-?1 is RET kinase inhibitor. It can be used in biological study of composition and function of mutant Swi?/Snf complexes. It can also be used in biological study of proteomics study of medullary thyroid carcinomas expressing RET germ-line mutations and identification of new signaling elements. | [Biological Activity]
rpi-1 is an atp-dependent ret tyrosine kinase and inhibitor [1]. rpi-1 also inhibits c-met activation and expression [2].the ret proto-oncogene encodes a receptor protein tyrosine kinase involved in the etiology of human tumors. ret loss of function mutations are associated with the development of hirschsprung's disease, and gain of function mutations are associated with the development of various types of human cancer, including medullary thyroid carcinoma, multiple endocrine neoplasias, pheochromocytoma and parathyroid hyperplasia.in nih3t3 fibroblasts expressing the ret/ptc1 target tyrosine kinase (nih3t3ptc1), rpi-1 preferentially inhibited the anchorage-independent growth with ic50 value of 0.97 μm [1]. in the n592 sclc and h460 nsclc cell lines, rpi-1 dose-dependently inhibited met phosphorylation. in h460 cells, rpi-1 also inhibited hgf-induced met tyrosine phosphorylation in a dose-dependent way [2].in mice implanted s.c. with h460 cells, rpi-1 with 100 and 150 mg/kg significantly reduced the mean number of macroscopic lung metastases by 57% and 75%, respectively. in primary s.c. growing h460 tumors, rpi-1 exhibited significant antiangiogenic effect [2]. | [in vivo]
RPI-1 (50, 100 mg/kg; p.o.; twice a day for 10 days) inhibits the tumor growth of TT xenografts by 81%[2]. | Animal Model: | 8- to 11-week-old female athymic nude CD-1 mice (bearing TT cells)[2] | | Dosage: | 50, 100 mg/kg | | Administration: | P.o.; twice a day for 10 days | | Result: | A dose-dependent effect on tumor growth was observed, with a dose of 2*50 mg/kg/day resulting in less tumor weight inhibition than the 2*100mg/kg/day dose after 10 days of treatment.
