AVL-292, al inhibir las actividades de BTK, inhibe aún más la proliferación de células B con EC50 de 3 nM. En un modelo de ratón con artritis inducida por colágeno, AVL-292 (3-30 mg / kg, po) inhibe de forma dosis-dependiente los signos clínicos de la enfermedad inflamatoria, incluida la reducción de la hinchazón de las articulaciones y las patas y el enrojecimiento visible de las patas afectadas.

Procedures for BTK OMNIA Assay
|
The Omnia continuous read assay is performed essentially as described by the vendor. The assay conditions are: 40 μM ATP (1X KMATP), 10 μM Y5-Sox, and 10 nM BTK enzyme. Briefly, a substrate mix containing 1.13X ATP and the Y5 Sox substrate is first prepared in 1X Omnia Kinase Reaction Buffer (KRB) consisting of 20 mM Tris, pH 7.5, 5 mM MgCl2, 1 mM EGTA, 5 mMβ-glycerophosphate, 5% glycerol, and 0.2 mM DTT. For IC50 measurements, 5 μL of enzyme are incubated with serially diluted (3-fold) compounds prepared in 50% DMSO in a Corning (#3574) 384-well, white, non-binding surface microtiter plate at 25°C for 30 min. Kinase reactions are started with the addition of 45 μL of the ATP/Y5 substrate mix and monitored at λex360/λem485 in a Synergy 4 plate reader for 60 minutes. Progress curves from each well are examined for linear reaction kinetics and fit statistics. Initial velocity from each reaction is determined from the slope of a plot of relative fluorescence units versus time and then plotted against inhibitor concentration to estimate IC50 using the Response, Variable Slope model in GraphPad Prism from GraphPad Software.

Method

A suspension of resting purified naïve human B cells isolated by negative selection in RPMI is prepared at 0.4–0.5 × 106 cells/ml. Cells are mixed together with α-human IgM (final concentration of 5 μg/ml in each well) and vehicle (dimethyl sulfoxide) or AVL-292 (final concentrations of 0.01, 0.1, 1.0, 10.0, 100.0, or 1000 nM per well) and seeded in a 96-well plate. Cells are incubated for 56 hours in a humidified incubator maintained at 37°C and 5% CO2. 3H-Thymidine is added (final concentration of 1 μCi in each well) and cells are incubated overnight, harvested, and measured for 3H incorporation. Experiments are performed in triplicate.

Por ejemplo, para modificar la dosis de resveratrol utilizada para un ratón (22,4 mg / kg) a una dosis basada en el BSA para una rata, multiplique 22,4 mg / kg por el factor Km para un ratón y luego divida por el factor Km para una rata. Este cálculo da como resultado una dosis equivalente para ratas de resveratrol de 11,2 mg / kg.
