Abstract
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. Early apoptosis and necrosis were detected by double staining of annexin V/ propidium iodide and activity of caspase 3 as the final mediator in apoptotic mode of cell death was evaluated by colorimetric assay. Results: Our results showed that β lactam derivatives inhibited the proliferation of cancerous lymphoblast but not normal lymphocytes in a concentration-dependent mode by inducing apoptosis. Treatment with β lactam derivatives resulted in a rapid loss of mitochondrial trans-membrane potential and induction of reactive oxygen species (ROS) formation, and cytochrome c release in cytosol of mitochondria resulted in activation of procaspase-9 and formation of active apoptosome. Conclusion: These findings suggest that 4-(4-(Methylsulfonyl)phenyl)-1-pentyl-3-phenoxyazetidin-2-one as a β lactam could induce ROS-mediated death signaling throughmitochondrial pathway that results in apoptosis in only cancerous lymphoblast cells. The stimulationof apoptosis by β lactams may provide a pivotal mechanismfor their anticancer effect in acute lymphocytic leukemia cells.Keywords: Mitochondria, cox-2 inhibitors, β lactam, apoptosis, acute lymphocytic leukemia.

Discovery of Lead compounds targeting transcriptional regulation
Transcriptional regulation plays key physiological functions in body growth and development. Transcriptional dysregulation is one of important biomarkers of tumor genesis and progression, which is involved in regulating tumor cell processes such as cell proliferation, differentiation, and apoptosis. Additionally, it plays a pivotal role in angiogenesis and promotes tumor metastasis ...read more
Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes and aid in stabilizing chromosomal makeup. Resynthesis of telomeres supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no any telomerase activity in human somatic cells, but the stem cells and germ cells undergone telomerase ...read more
