Biological Activity

AUY922 (NVP-AUY922) is a small molecule Heat Shock Protein 90 (HSP90) inhibitor with IC50 values of 13 and 21 nM for HSP90α and HSP90β respectively. AUY922 (NVP-AUY922) potently inhibits HSP90 (Kd = 1.7 nmol/L) and proliferation of human tumor cells with GI50 values of approximately 2 to 40 nmol/L, inducing G1-G2 arrest and apoptosis. AUY922 (NVP-AUY922) inhibited proliferation, chemomigration, and tubular differentiation of human endothelial cells and antiangiogenic activity was reflected in reduced microvessel density in tumor xenografts.

Preparation method Proliferation assays
Cells were seeded in duplicate at 5,000-10,000 cells per well. The day after plating (day 1), NVP-AUY922 was added at 1 µM and 2-fold dilutions over 12 concentrations. Data were compared to untreated controls. Cells were counted on the day drug was added and five days later and these two counts were compared. Cells were harvested by trypsinization and counted immediately using a Coulter Z2 particle counter (Beckman Coulter Inc, Fullerton, CA). Percent growth inhibition, defined as 100 × (1 - [generations in treated wells/generations in untreated controls]) was determined. Experiments were performed in duplicate. Error bars represent standard error for each experiment. Non-linear curve fitting was performed by fitting curves to data points using the Proc NLIN function in SAS for Windows version 9.2 (SAS Institute, Inc., Cary, NC) using a basic four-parameter sigmoid model. IC50 (concentration needed to prevent 50% of cell population doublings) and IC100 (complete inhibition of proliferation) were the summary outcome measures interpolated from the resulting curves.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
