Since synthetic analogs of 1,4-anthraquinone (AQ code number), such as AQ8, AQ9 and AQ10, can trigger cytochrome c release without caspase activation and retain their ability to induce apoptosis in multidrug-resistant (MDR) tumor cells, fluorescent probes of transmembrane potential have been used to determine whether these anti-tumor compounds might directly target mitochondria in cell and cell-free systems to cause the collapse of mitochondrial membrane potential (/Deltapsim) that is linked to permeability transition pore (PTP) opening.

Synthetic analogs of 1,4-anthraquinone (AQ code number), which block nucleoside transport, decrease DNA, RNA and protein syntheses, trigger cytochrome c release without caspase activation, induce apoptotic DNA fragmentation and inhibit the proliferation of wild-type and multidrug resistant tumor cells in the nM range in vitro, rapidly cause the collapse of mitochondrial transmembrane potential in cell and cell-free systems.

In Vivo. 2009 Mar-Apr;23(2):309-16.

Rhein, an anthraquinone compound, can be found in the rhizome of rhubarb, a traditional Chinese medicine herb showing antitumor activity.

15037204 Perchellet EM, Wang Y, Weber RL, Sperfslage BJ, Lou K, Crossland J, Hua DH, Perchellet JP: Synthetic 1,4-anthracenedione analogs induce cytochrome c release, caspase-9, -3, and -8 activities, poly (ADP-ribose) polymerase-1 cleavage and internucleosomal DNA fragmentation in HL-60 cells by a mechanism which involves caspase-2 activation but not Fas signaling. Biochem Pharmacol. 2004 Feb 1;67(3):523-37.

Synthetic analogs of 1,4-anthraquinone (AQ code number), a compound that mimics the antiproliferative effects of daunorubicin (daunomycin) in the nanomolar range in vitro but has the advantage of blocking nucleoside transport and retaining its efficacy in multidrug-resistant tumor cells, were tested for their ability to induce apoptosis in the HL-60 cell system.
In accord with the fact that the caspases 9 and 3 cascade is responsible for PARP-1 cleavage, the activities of initiator caspase-9 and effector caspase-3 are induced by AQ9 in the same time- and concentration-dependent manners and to the same maximal degrees in both the HL-60-S and multidrug-resistant HL-60-RV cell lines.

Emodin, a natural anthraquinone derivative isolated from Rheum palmatum L., has been reported to exhibit anti-cancer effect on several human cancers such as liver cancers and lung cancers.
Ectopic expression of Bcl-2, or treatment with aurintricarboxylic acid, furosemide or caspase inhibitors markedly blocked emodin-induced apoptosis.

Rhein is an anthraquinone compound enriched in the rhizome of rhubarb, a traditional Chinese medicine herb showing anti-tumor promotion function.
In this study, we first reported that rhein could induce apoptosis in human promyelocytic leukemia cells (HL-60), characterized by caspase activation, poly (ADP) ribose polymerase (PARP) cleavage, and DNA fragmentation.

SZ-685C-induced apoptosis was assessed by Annexin V-fluorescein isothiocyanate/propidium iodide staining, terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling assay and analysis of caspase activation.

Moreover, this apoptotic induction was associated with a collapse of the mitochondrial membrane potential and activated caspases (cysteine aspartase) cascade involving in caspase-8, caspase-9, caspase-3, and poly (ADP-ribose) polymerase cleavage in a concentration-dependent manner.

Anthraquinone compounds have been shown to induce apoptosis in different cancer cell types.
Non-apoptotic cell death was induced by chrysophanol in J5 cells and was characterized by caspase independence, delayed externalization of phosphatidylserine and plasma membrane disruption.

Our previous studies showed that a naphthoquinone and an anthraquinone (emodin) displayed the capability of producing ROS and facilitating arsenic cytotoxicity in both leukemia and solid tumor cell lines.
The combination of emodin and arsenic promoted the major apoptotic signaling events, i.e., the collapse of the mitochondrial transmembrane potential, the release of cytochrome c, and the activation of caspases 9 and 3.
