Além disso, WZ4003 (10 μM) inibe a fosforilação MYPT1 Ser445, bem como a migração, invasão e proliferação celular em uma extensão semelhante ao knock out em MEFs ou knock down em células U2OS de NUAK1. WZ4003 também exibe uma alta afinidade específica para o EGFR mutante L858R / T790M, enquanto um IC50 celular significativamente reduzido contra T790M contendo células Ba / F3. \ n Protocolo (apenas para referência) Ensaio de cinase: [1]

IC50 determination
|
Active GST–NUAK1, GST–NUAK1[A195T] and GST–NUAK2 enzymes are purified using glutathione–Sepharose from HEK-293 cell lysates 36–48 h following the transient transfection of pEBG2T mammalian constructs expressing N-terminal GSTtagged NUAK1, NUAK1[A195T] or NUAK2. For peptide kinase assays, 96-well plates are used, and each reaction is performed in triplicate. Each reaction is set up in a total volume of 50 μL containing 100 ng of NUAK1 (wild-type or A195T mutant) or NUAK2 in 50 mM Tris/HCl (pH 7.5), 0.1 mM EGTA, 10 mM magnesium acetate, 200 μM Sakamototide, 0.1 mM [γ -32P]ATP (450–500 c.p.m./pmol) and the indicated concentrations of inhibitors dissolved in DMSO. After incubation for 30 min at 30°C, reactions are terminated by adding 25 mM (final) EDTA to chelate the magnesium. Then, 40 μL of the reaction mix is spotted on to P81 paper and immersed in 50 mM orthophosphoric acid. Samples are washed three times in 50 mM orthophosphoric acid followed by a single acetone rinse and air drying. The incorporation of [γ -32P]ATP into Sakamototide is quantified by Cerenkov counting. The values are expressed as a percentage of the DMSO control. IC50 curves are developed and IC50 values are calculated using GraphPad Prism software.

Cell proliferation assays are carried out colorimetrically in 96-well plates using the CellTiter 96 AQueous Non-Radioactive Cell Proliferation Assay kit following the manufacturer`s protocol. Initially, 2000 cells per well are seeded for U2OS cells and 3000 cells per well are seeded for MEFs. The proliferation assays are carried out over 5 days in the presence or absence of 10 μM WZ4003.

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.
