Description	GNF-5837 is a selective, and orally bioavailable pan-TRK inhibitor for TrkA, and TrkB with IC50 of 8 nM, and 12 nM, respectively.
Targets	TrkC [1]	TrkB [1]	TrkA [1]	PDGFRβ [1]	Kit [1]	&nbsp&nbsp&nbspView More
IC50	7 nM	9 nM	11 nM	0.87 μM	0.91 μM
In vitro	In Ba/F3 cells overexpressing the constitutively active Tel-TRKC fusion, GNF-5837 shows potent anti-Trk activity and potent antiproliferation activity with IC50 of 0.042 μM.
In vivo	In both male Balb/c mice and Sprague–Dawley rats, GNF-5837 has the low drug clearance, and moderate biovailability. In mice bearing Rie xenografts expressing TrkA and NGF, GNF-5837 (100 mg/kg/d p.o.) significantly inhibits tumor growth.

Inhibition of biochemical TrkA, TrkB and TrkC

TrkA and TrkC biochemical assays are carried out by HTRF method. The reaction mixtures contains 1 μM peptide substrate, 1 μM ATP, and either 1.8 nM TrkA or 34 nM TrkC in the reaction buffer (50mM HEPES pH 7.1, 10mM MgCl2, 2 mM MnCl2, 0.01% BSA, 2.5 mM DTT and 0.1 mM Na3VO4) at a final volume of 10 μL. All reactions are carried out at room temperature in white ProxiPlate™ 384-well Plus plates and are quenched with 5 μL of 0.2 M EDTA at 60 min. Five μL of the detection reagents (2.5 ng PT66K and 0.05 μg SAXL per well) are added, the plates are incubated at room temperature for 1 h and then read in EnVision reader. Compounds are diluted into assay mixture (final DMSO 0.5%), and IC50 values are determined by 12-point (from 50 to 0.000282 μΜ) inhibition curves in duplicate under the assay conditions. TrkB biochemical assay is carried out by caliper microfluidic method. The reaction mixtures contained 1 μM peptide substrate, 10 μM ATP, and 2 nM TrkB in a reaction buffer containing 100 mM HEPES, pH 7.5, 5 mM MgCl2, 0.01% Triton X-100, 0.1% BSA, 1 mM DTT, 10 μΜNa3VO4, and 10 μΜBeta-Glycerophosphate. The reactions are carried out at room temperature for 3 hrs, and the products are determined by Caliper EZ-reader. Compounds are diluted into assay mixture (final DMSO 1%), and IC50 values are determined by 12-point (from 50 to 0.000282 μΜ) inhibition curves in duplicate under the assay conditions.

Ensaio de células: [1]

Cell lines	Wt Ba/F3 cells and Ba/F3 cells transformed with constitutively expressed luciferase reporter and BCR-ABL or Tel-KDR or other Tel fusion kinases
Concentrations	~10 μΜ
Incubation Time	48 hours
Method	Compounds are tested for their ability to inhibit the proliferation of wt Ba/F3 cells and Ba/F3 cells transformed with constitutively expressed luciferase reporter and BCR-ABL or Tel-KDR or other Tel fusion kinases. Parental Ba/F3 cells are maintained in media containing recombinant mouse IL3 and the kinase transformed Ba/F3 cells are maintained in media without IL-3. 7.5 nL of compounds are spotted to each well of 1536-well assay plates by Liquid handling System Echo 555 (Labcyte). 700 cells are then plated into each well of the assay plates in 7 μL culture media per well and compounds are tested at 0.17 nM to 10 uM in 3-fold serial dilutions. The cells were then incubated for 48 hours at 37 °C. 3 μL of Bright-Glo® is added to each well and the plates are read using ViewLux.

Body Surface Area (m2)	0.6	0.5	0.24	0.15	0.05	0.025	0.02	0.007
Km factor	20	20	12	12	8	6	5	3

Animal A (mg/kg) = Animal B (mg/kg) multiplied by	Animal B Km
	Animal A Km

Por exemplo, para modificar a dose de resveratrol usada para um camundongo (22,4 mg / kg) para uma dose baseada na BSA para um rato, multiplique 22,4 mg / kg pelo fator Km para um camundongo e, em seguida, divida pelo fator Km para um rato. Este cálculo resulta em uma dose equivalente de rato para o resveratrol de 11,2 mg / kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×	mouse Km(3)	= 11.2 mg/kg
