 5.000mg/ml (10.03mM) Taking the 1 mL working solution as an example, add 300 μL of clarified propylene glycol stock solution of 16.67 mg/ml to 50 μL of Tween 80, mix evenly to clarify it; then continue to add 650 μL of D5W to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Biological Activity

Description GDC-0152 is a potent antagonist of XIAP-BIR3, ML-IAP-BIR3, cIAP1-BIR3 and cIAP2-BIR3 with Ki of 28 nM, 14 nM, 17 nM and 43 nM in cell-free assays, respectively; less affinity shown to cIAP1-BIR2 and cIAP2-BIR2. Phase 1.

In vitro GDC-0152 can block protein−protein interactions that involve IAP proteins and pro-apoptotic molecules. Using transiently transfected HEK293T cells, GDC-0152 is shown to disrupt XIAP binding to partially processed caspase-9 and to disrupt the association of ML-IAP, cIAP1, and cIAP2 with Smac. In melanoma SK-MEL28 cells, the endogenous association of ML-IAP and Smac is effectively also abolished by GDC-0152. GDC-0152 lead to a decrease in cell viability in the MDA-MB-231 breast cancer cell line, while having no effect on normal human mammary epithelial cells (HMEC). GDC-0152 is found to activate caspases 3 and 7 in a dose- and time-dependent manner. GDC-0152 is shown to induce rapid degradation of cIAP1 in A2058 melanoma cells. It effectively induces degradation of cIAP1 at concentrations as low as 10 nM, consistent with its affinity for cIAP1.
In vivo GDC-0152 has moderate predicted hepatic clearance based on metabolic stability assays conducted using human liver microsomes. Plasma−protein binding of GDC-0152 is moderate and comparable among mice (88−91%), rats (89−91%), dogs (81−90%), monkeys (76−85%), and humans (75−83%) over the range of concentrations investigated (0.1−100 μM); higher plasma−protein binding is observed in rabbits (95−96%). GDC-0152 does not preferentially distribute to red blood cells with blood−plasma partition ratios ranging from 0.6 to 1.1 in all species tested. The pharmacokinetics for GDC-0152 is achieved with a C max of 53.7 μM and AUC of 203.5 h•μM. [1]

Protocol (from reference)

Kinase Assay:[1]
  • Fluorescence polarization-based competition assay

    Inhibition constants ( Ki ) for the antagonists are determined by addition of the IAP protein constructs to wells containing serial dilutions of the antagonists or the peptide AVPW, and the Hid-FAM probe or AVP-diPhe-FAM probe, as appropriate, in the polarization buffer. Samples are read after a 30-minute incubation. Fluorescence polarization values are plotted as a function of the antagonist concentration, and the IC50 values are obtained by fitting the data to a 4-parameter equation using software. Ki values for the antagonists are determined from the IC50 valued.

Customer Product Validation

<p>Inhibitor of Apoptosis Proteins (IAPs) were involved in MCP-1/IL-6 production under high dose TNF-α stimulation. A. hUC-MSCs (2x104 in 96-well plates) were pretreated for 2h with the IAP inhibitor GDC-0152 at increasing concentrations (0-1000 nM), then stimulated with TNF-α (20 ng/ml, 1.2 nM). After a further 24h, trypan blue was used to exclude cell toxicity. SN was collected and IL-6 and MCP-1 concentrations were measured by ELISA. B. hUC-MSCs(5×105 in T25 bottle) were pretreated with GDC-0152(1000nM) for 2 h, then stimulated with TNF-α (20 ng/ml, 1.2 nM). 24 hours later, protein from nucleus and cytoplasma were extracted separately and the amount of NF-kB were detected by Western blot. Data are as mean±SEM of triplicate measurements; *p<0.05, **p<0.01, ***p<0.001 when compared to untreated cells. These experiments were repeated 3 times with the same results, using clone 69 and another TNF-α sensitive clone (clone 120003).</p>

(a) Apoptosis (SubG0/G1) of DMSO control and GDC-0152-treated cells was determined by flow cytometry of propidium iodide-stained nuclei and percentage of apoptosis is shown. U87MG and GL261 cell lines were treated for 72 h and GBM6 and GBM9 cell lines were treated for 8 days at the indicated concentrations. At these respective time points, percentage of U87MG cells dead by apoptosis, percentage of GL261 cells, percentage of GBM6 cells and percentage of GBM9 cells. Data are expressed as mean+S.E.M. Three independent experiments were performed for the GL261 cell lines and five for the U87MG, GBM6 and GBM9 cell lines. *P<0.05; **P<0.01; ***P<0.005.

GDC-0152 sensitises FTC cell lines for TRAIL-induced apoptosis. FTC cell lines were treated with increasing concentrations of rh-TRAIL with and without Smac mimetics GDC-0152. Changes in cell viability are illustrated linearly in percentage control and stratified according to the FP. While FTC cell line TT2609-bib2 was susceptible to rh-TRAIL alone (C), cell line FTC133 proved to be resistant to rh-TRAIL-induced apoptosis (D). Smac mimetic treatment alone had no impact on cell viability. Annexin V/PI staining and FACS analyses of FTC cells demonstrate the changes of annexin positive apoptotic cells after incubation with rh-TRAIL alone (−) or in combination (+) with Smac mimetics Birinapant GDC-0152 (C/D). Changes in protein expression of cIAP1/2 after treatment with the respective Smac mimetic are illustrated using Western blot. GAPDH served as loading control. Blots are cropped to increase clarity. Statistical significance was calculated by two-tailed nonparametric Mann–Whitney test. e. survival:expected survival; sp. survival: specific survival; FP: fractional product; *P < 0.05; **P < 0.01.
