Apoptosis Activator 2 Caspase activator

Cat.No.S2927

Apoptosis Activator 2 strongly induces caspase-3 activation, PARP cleavage, and DNA fragmentation which leads to the destruction of cells (Apaf-1 dependent) with IC50 of ~4 μM, inactive to HMEC, PREC, or MCF-10A cells.

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.

Mechanism of Action

Targets/IC50/Ki
Caspase-3 [1]
In vitro
Apoptosis Activator 2 (20 μM) at the reduced cyto c concentration increases the fraction of Apaf-1 in the apoptosome by 1.5-fold to 33%. This compound increases the extent of caspase-3 activation at the reduced level of cyto c and caspase-3 activation by 4-fold. It strongly indues caspase-3 activation, PARP cleavage, and DNA fragmentation, and finally killing cells with an IC50 of 4 μM. This activator induces apoptosis of PBL, HUVEC, Jurkat, Molt-4, CCRF-CEM, BT-549, MDA-MB-468 and NCI-H23 with of IC50 of 50 μM, 43 μM, 4 μM, 6 μM, 9 μM, 20 μM, 44 μM and 35 μM. It exerts a cytostatic effect on the majority of tumor cell lines tested, inhibiting cell growth by 50-100% at 10 μM in 40 of 48 cell lines tested. [1] This chemical induces cell death by triggering apoptosome formation. The level of En1 expression does not have a significant influence on the survival rates of Ventral midbrain cultures for this compound (-8.1 ± 6.0%). Survival rate is not significantly altered if the other three reagents are employed (-10.7 ± 4.7%) for this activator. [2] This compound (10 μM) induces apoptosis in AGS cells as evaluated by apoptotic DNA ladder and Tunel assay. It (10 μM) enhances the induction of apoptosis by anti TROP2 conjugated liposomes. [3] Cyclohexamide (10 μg/mL) or zVAD (50 μM) significantly protects against this chemical toxicity in neuroneal cultures. This activator (3 μM) results in numerous neurones with pyknotic nuclei suggestive of cell death involving apoptosis. DHT (10 nM) or E2 (10 nM) significantly protects against this compound toxicity in neuroneal cultures. [4]
Kinase Assay
Cell-Free Apoptosis Assay
HeLa cell cytoplasmic extracts are prepared according to previously published reports. Apoptosis Activator 2 in DMSO are distributed into 96-well microtiter plates at a final concentration of 1 mM (final DMSO concentration is 1% vol/vol). To each well is added 250 μg of total protein from cytoplasmic extracts in HEB buffer (50 mM Hepes, pH 7.4/50 mM KCl/5 mM EGTA/2 mM MgCl), with 2 mM DTT, 2 μM cyto c, and 0.5 μM DEVD-AFC (Asp-Glu-Val-Asp-7-amino-4-trifluoromethylcoumarin) substrate in a total of 150 μL. Plates are incubated at 37 ℃, and fluorescence is read in a LJL Biosystems plate reader at 10-min intervals.
