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.

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 Research:[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 Research:[2]
  • Animal Models: Male nude mice
  • Dosages: 10 mg/kg
  • Administration: i.p.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
