Solubility (25°C)* In vitro DMSO 100 mg/mL (159.85 mM)
Ethanol 25 mg/mL (39.96 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 95% Corn oil
1.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 20 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 50 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O 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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Apoptozole (Apoptosis Activator VII) is an inhibitor of heat shock protein 70(HSP70) and Hsc70 with dissociation constants Kd of 0.14 μM and 0.21 μM, respectively. It induces caspase-dependent apoptosis.
Targets
HSP70 [1]
(Cell-free assay)		 HSC70 [1]
(Cell-free assay)
0.14 μM(Kd) 0.21 μM(Kd)
In vitro Apoptozole induces caspase dependent apoptosis by blocking interaction of HSP70 with APAF-1, without affecting interactions of HSP70 with ASK1, JNK, BAX, and AIF[2]. However, apoptozole may form aggregates under aqueous conditions that could interact with HSP70 proteins in a non-specific manner, potentially leading to false positives and inconsistent data[3].
In vivo Apoptozole greatly retards tumor growth in mice xenografted with cancer cells without affecting mouse viability. The elimination half-life time (T1/2) of Az in blood is found to be significantly longer than that of Dox (8.04 versus 1.60 hr) and the time needed to reach a maximum concentration (Tmax) of Az is shorter than that of Dox (1.00 versus 4.00 hr)[2].

Protocol (from reference)

Cell Assay:[2]
  • Cell lines

    A549, lung adenocarcinoma epithelial cells; HeLa, cervical cancer cells; MDA-MB-231, breast cancer cells; HepG2, liver cancer cells

  • Concentrations

    0-15 μM

  • Incubation Time

    18 h

  • Method

    Several cancer cell lines (A549, lung adenocarcinoma epithelial cells; HeLa, cervical cancer cells; MDA-MB-231, breast cancer cells; HepG2, liver cancer cells) are treated with various concentrations (0-15 μM) of Az or compound 7 as a negative control for 18 hr. Cell viabilities are then determined using an MTT assay.
Animal Study:[2]
  • Animal Models

    Male nude mice

  • Dosages

    10 mg/kg

  • Administration

    i.p.
