Bioactivity

• Target IC50:
  HER2:37 nM|HSP90:41 nM
• In Vivo:
  PF-04929113 showed potent effects on Her-2 stability and led to the expected upregulation of Hsp70.PF-04929113 showed potent antiproliferative activity against a wide range of cancer cell types, e.g., MCF-7 (IC50 = 16 nM), SW620 (IC50 = 19 nM), K562 (IC50 = 23 nM), SK- MEL-5 (IC50 = 25 nM) and A375 (IC50 = 51 nM).

• Cell Research:
  Cell lines: MCF-7,SW620,K562,SK-MEL-5 and A375 cancer cell lines. Concentrations: 0-300 nM. Method: Proliferation rates are measured by seeding cells into 96-well plates,followed by compound addition 24 h later.After addition of PF-04929113,cells are allowed to grow for either an additional 72 or 144 h depending on the rate of growth.At harvest,media is removed and DNA content for individual wells is determined using CyQuant DNA dye.Levels of Hsp90 client proteins and phosphor-regulated proteins in A375 are measured by high content analysis (HCA) using an ArrayScan 4.5 instrument after 24 hours of treatment with PF-04929113,followed by methanol fixation.After fixation in 4% PBS-buffered formalin and permeablization with 0.1% TX-100,cells are probed with anti-Her2,antiphospho-S6 (pS6),antipERK,and anti-Hsp70 primary antibodies,followed by TRITC or FITC conjugated secondary antibodies.Nuclei are also stained with Hoechst DNA binding dye.For each well,250-500 individual nuclei are identified along with the average staining intensity for the client and phospho-proteins for each cell.Average client staining intensities are then calculated for each well.
