Product Introduction

Bioactivity

Description	Larotrectinib sulfate (LOXO-101 sulfate) is an oral active and specific ATP-competitive inhibitor of tropomyosin receptor kinases (TRK).
In vitro	Larotrectinib is a specific kinase inhibitor with nanomolar activity against TRKA/TRKB/TRKC but no other notable kinase inhibition (1 μM). Larotrectinib hasn't the inhibitory of the proliferation of Ba/F3 cells expressing other oncogene targets (EGFR, ROS1 or ALK) or of lung and colorectal cell lines that do not harbor an NTRK1 fusion. It induces cell-cycle arrest in G1 and apoptosis of KM12 cells.
In vivo	Early/sustained but not late/acute administration of ARRY-470(LOXO-101) obviously attenuates bone cancer pain and blocks the ectopic sprouting of sensory nerve fibers and the formation of neuroma-like structures in the tumor-bearing bone, but no significant inhibition for tumor growth or bone remodeling. It has very limited ability crossing of the blood-brain barrier.
Cell Research	Concentrations: 10,100,1000 nM. Method: Ba/F3 cells expressing MPRIP-NTRK1 (RIP-TRKA) or EV were lysed after 5 h of treatment with the indicated doses of drugs (ARRY-470; G,gefitinib 1,000 nM) or DMSO control.The cell lysate is used for western blot analysis.
Animal Research	Animal Models: Adult male C3H/HeJ mice. Formulation: Labrafac; polygly-colyzed glyceride. Dosages: 10-100 mg/kg. Administration: p.o.
Synonyms	LOXO-101 sulfate, LOXO-101 (sulfate), ARRY-470 (sulfate)

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.
