RET-IN-4

😃Good
Catalog No. T40097Cas No. 2436473-55-9

RET-IN-4 is a highly effective and specific RET inhibitor that can be administered orally. It demonstrates remarkable potency, with IC50 values of 1.29 nM, 1.97 nM, and 0.99 nM for inhibiting RET variants including RET (WT), RET (V804M), and RET (M918T), respectively. Moreover, RET-IN-4 exhibits superior selectivity towards kinases JAK2 (IC50 of 4.4 nM) and FLT3 (IC50 of 30.8 nM). Additionally, RET-IN-4 possesses pronounced anticancer properties.

It demonstrates remarkable potency, with IC50 values of 1.29 nM, 1.97 nM, and 0.99 nM for inhibiting RET variants including RET (WT), RET (V804M), and RET (M918T), respectively. Moreover, RET-IN-4 exhibits superior selectivity towards kinases JAK2 (IC50 of 4.4 nM) and FLT3 (IC50 of 30.8 nM). Additionally, RET-IN-4 possesses pronounced anticancer properties.
Targets&IC50
RET (WT):1.29 nM (IC50), RET (M918T):0.99 nM (IC50), RET (V804M):1.97 nM (IC50)
In vitro
RET-IN-4 (compound 9) effectively inhibits the proliferation of Ba/F3 cells transformed by the NSCLC-associated KIF5B-RET fusion, with an IC50 value of 19 nM. Compared to BLU-667[1], RET-IN-4 demonstrates fewer 'off-target' effects.
In vivo
RET-IN-4 (compound 9; p.o.; 10-20 mg/kg; p.o.; daily; for 10 days) effectively suppresses KIF5B-RET-Ba/F3 cell-induced tumor growth in a dose-dependent manner in immunodeficient nude/nude mice models bearing KIF5B-RET Ba/F3 cells[1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
