产品名称：BIIB021
产品描述：
| 产品描述 | BIIB021 is an orally-available, fully synthetic inhibitor of HSP90(Ki=1.7 nM, EC50=38 nM). |
| 靶点活性 | HSP90:1.7 nM(Ki) |
| 体外活性 | 在多种移植瘤模型中,口服BIIB021能够有效抑制肿瘤的生长.在L540cy肿瘤中,BIIB021（120 mg/kg ）,能够抑制细胞的增殖. |
| 体内活性 | 在多种肿瘤细胞中（IC50=0.06-0.31 μM）,BIIB021能够抑制细胞生长,如BT474,MCF-7,N87,HT29,H1650,H1299,H69和H82。在霍奇金淋巴瘤细胞中（IC50=0.24-0.8 μM）,BIIB021抑制细胞增殖 ,如KM-H2,L428,L540,L540cy,L591,L1236和DEV。BIIB021诱导Hsp90蛋白（包括HER-2,Akt和Raf-1）的降解以及热休克蛋白Hsp70和Hsp27的上调表达。 |
| 激酶实验 | Hsp90 Binding Assay: For fluorescence polarization competition measurements, the FITC-geldanamycin probe (20 nM) is reduced with 2 mM TCEP at room temperature for 3 hours, after which the solution is aliquoted and stored at -80 °C until used. Recombinant human Hsp90α (0.8 nM) and reduced FITC-geldanamycin (2 nM) are incubated in a 96-well microplate at room temperature for 3 hours in the presence of assay buffer containing 20 mM HEPES (pH 7.4), 50 mM KCl, 5 mM MgCl2, 20 mM Na2MoO4, 2 mM DTT, 0.1 mg/mL BGG, and 0.1% (v/v) CHAPS. Following this preincubation, BIIB021 in 100% DMSO is then added to final concentrations of 0.2 nM to 10 μM (final volume 100 μL, 2% DMSO). The reaction is incubated for 16 hours at room temperature and fluorescence is then measured in an Analyst plate reader, excitation = 485 nm, emission = 535 nm. High and low controls contained no BIIB021 or no Hsp90, respectively. The data are fit to a four-parameter curve and IC50 is generated. |
| 细胞实验 | A modified tetrazolium salt assay is used to measure the IC50. Tumor cells are added to 96-well plates and propagated for 24 hours before BIIB021 addition. BIIB021 is added to the plated cells. DMSO (0.03-0.003%) is included as a vehicle control. After incubation phenazine methosulfate (stock concentration 1 mg/mL) and 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt (stock concentration 2 mg/mL) are mixed at a ratio of 1:20 and added to each well of a 96-well plate. Reduction of 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt gives rise to a soluble formazan product that is secreted into the culture medium. After 4 hours incubation, the formazan product is quantitated spectrophotometrically at a wavelength of 490 nm. Data are acquired using SOFTmaxPRO software, and 100% viability is defined as the A490 of DMSO-treated cells stained with 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt (the mean A490 of cells treated with DMSO at a range of 0.03-0.003%). Percent viability of each sample is calculated from the A490 values as follows: % viability = (A490 nm sample / A490 nm DMSO-treated cells × 100). The IC50 is defined as the concentration that gives rise to 50% inhibition of cell viabilit(Only for Reference) |
