生物活性

RPI-1 is a specific, orally available 2-indolinone Ret tyrosine kinase inhibitor. RPI-1 inhibits proliferation, Ret tyrosine phosphorylation, Ret protein expression, and the activation of PLCgamma, ERKs and AKT in human medullary thyroid carcinoma TT cells. Antitumor activity.

体外研究

TPC-1 cells are sensitive to the growth inhibitory effect of RPI-1 with an IC₅₀ of 5.1 μM, following 72 hours of treatment. RPI-1 (7.5-60 µM) inhibits Ret/Ptc1 autophosphorylation in TPC-1 cells. RPI-1 inhibitory effects in the TPC-1 cell culture conditions lead to inhibition of pathways involving JNK2 and AKT.
The RPI-1 IC₅₀ value for cell proliferation is 3.6 µM in NIH3T3 cells expressing the Ret mutant compared with 16 µM in non-transfected NIH3T3 cells, and that for colony formation in soft agar was 2.4 µM and 26 µM in RET mutant-transfected and H-RAS-transfected NIH3T3 cells, respectively. In NIH3T3 cells expressing the Ret mutant, Ret protein and tyrosine phosphorylation were undetectable after 24 hours of RPI-1 treatment. In TT cells, RPI-1 inhibits proliferation, Ret tyrosine phosphorylation, Ret protein expression, and the activation of PLCgamma, ERKs and AKT.

体内研究

RPI-1 (50, 100 mg/kg; p.o.; twice a day for 10 days) inhibits the tumor growth of TT xenografts by 81%.

Animal Model:	8- to 11-week-old female athymic nude CD-1 mice (bearing TT cells)
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 250 mg/kg/day resulting in less tumor weight inhibition than the 2100mg/kg/day dose after 10 days of treatment.

请依序添加每种溶剂： 10% DMSO 90% (20% SBE-β-CD in saline)
Solubility: 2.08 mg/mL (7.00 mM); Suspended solution; Need ultrasonic

此方案可获得 2.08 mg/mL (7.00 mM) 的均匀悬浊液，悬浊液可用于口服和腹腔注射。
以 1 mL 工作液为例，取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中，混合均匀。
