In vitro EVALUATION of THE EFFECTS of POTENTIAL GSK-3β INHIBITORS TERBUTALINE and ORCIPRENALINE

Lung cancer is a type of cancer that is mostly diagnosed at an advanced stage and has a short survival time despite standard chemotherapy and targeted therapies. Terbutaline and Orciprenaline are bronchodilator agent that are potent and selective β2 receptor agonists. The purpose of this study was to investigate by continuous monitoring to assay the effects of Terbutaline and Orciprenaline on human lung carcinoma cell line. Cells were treated 1, 10, 100, 200, 400 µM concentrations with Terbutaline/Orciprenaline. MTT assay and xCELLigence real-time cell analyzer were used to determine these compounds effect on cell viability. The cell index was monitored continuously by visualizing the impedance of the E-plate wells. Because of GSK3β roles in a diverse range of cellular processes like metabolism, cell proliferation, differentiation and survival and its key position at several signaling pathways, GSK3β inhibition was investigated of these molecules. It has been determined that Terbutaline and Orciprenaline inhibits GSK-3β. This is the first known study to demonstrate the effects of Terbutaline and Orciprenaline on A549 and the human bronchial epithelial cell line Beas-2b in real time. In this study, it was detected that Terbutaline and especially Orciprenaline may have potential therapeutic effects in lung carcinoma.
