Chrysin as an Anti-Cancer Agent Exerts Selective Toxicity by Directly Inhibiting Mitochondrial Complex II and V in CLL B-lymphocytes.

We investigated the effect of chrysin on isolated normal and chronic lymphocytic leukemia (CLL) B-lymphocytes and their isolated mitochondria. We report that a selective and significant increase in cytotoxicity, intracellular reactive oxygen species, mitochondrial membrane potential collapse, ADP/ATP ratio, caspase 3 activation and finally apoptosis in chrysin-treated CLL B- lymphocytes. Also we determined that chrysin selectively inhibits complex II and ATPases in cancerous mitochondria.

β-lactam Structured, 4-(4-(Methylsulfonyl)phenyl)-1-pentyl-3-phenoxyazetidin-2-one: Selectively Targets Cancerous B Lymphocyte Mitochondria.

Background: β lactam-structured Cox-2 inhibitors, possesses anti-proliferative and anti-inflammatory effects.

Objective: In this research, the actions of a synthetic β lactam-structured Cox-2 inhibitor with 4-(4- (Methylsulfonyl) phenyl)-1-pentyl-3-phenoxyazetidin-2-one on cellular viability of cancerous lymphoblast obtained from patients with acute lymphocytic leukemia (ALL) and normal lymphocytes obtained from healthy donors were compared.

Methods: % the cell viability of cancerouslymphoblasts and normal lymphocytes treated with β lactam derivatives were assayed with MTT test.

Selective Anticancer Activity of Acacetin Against Chronic Lymphocytic Leukemia Using Both In Vivo and In Vitro Methods: Key Role of Oxidative Stress and Cancerous Mitochondria.

The present study investigates the in vitro and in vivo effect of acacetin (4'-methoxy-5,7-dihydroxyflavone) on chronic lymphocytic leukemia (CLL) B-lymphocytes and mitochondria. CLL B-lymphocytes and healthy B-lymphocytes were obtained from CLL patients and healthy donors, respectively. Mitochondria were isolated from B-lymphocytes of both groups.

Ellagic acid, a polyphenolic compound, selectively induces ROS-mediated apoptosis in cancerous B-lymphocytes of CLL patients by directly targeting mitochondria.

To investigate the effects ofellagic acid (EA) on the cytotoxicity, B-lymphocytes isolated from CLL patients and healthy individuals. Flow cytometric assay was used to measure the percentage of apoptosis versus necrosis, intracellular active oxygen radicals (ROS), mitochondrial membrane potential (MMP) and the caspase-3 activity and then mitochondria were isolated from both groups B-lymphocytes and parameters of mitochondrial toxicity was investigated. Based on our results EA decreased the percentage of viable cells and induced apoptosis.
