Master Thesis Synthesis of 1,2,3-Triazole Substituted Azacoumarin Derivatives as Potential Antiproliferative Compounds(01. Izmir Institute of Technology, 2021) Çağır, Ali; Çağır, Ali; 04.01. Department of Chemistry; 04. Faculty of Science; 01. Izmir Institute of TechnologyCancer is one of the deadly diseases that affects millions of people every year and causes death. Although studies toward its treatment are very promising, they are not sufficient. Therefore, the need for new and powerful molecules with less side effects is increasing day by day. 1-Azacoumarin derivatives are molecules whose potential biological activity has just begun to be understood, but not enough research has been done on them. 1,2,3-Triazole structures, on the other hand, are a very important family of molecules in some drugs, whose biological effects have been known for many years. It is known that they have important roles in cancer-preventing mechanisms in various types of cancer. In this study, two different 1,2,3-triazole 1-azacoumarin derivatives were tried to be synthesized. For structure 149, it was aimed to form yinon first and then formation of 1,2,3-triazole was studied but failed. Afterwards, the emphasis was placed on the production of 1-azacoumarin, and then click chemistry experiments were carried out in the presence of copper (I) catalyst. Finally, click chemistry studies were tested in the presence of a nickel catalyst for structure 150. Triazole formation experiments were carried out by click chemistry in the presence of copper catalyst after 1-azacoumarin was obtained.Master Thesis In-Vitro Evaluation Cytotoxic Potential of Novel Isoindole Derivatives on Various Cancer Cell Lines(01. Izmir Institute of Technology, 2021) Yemeztaşlıca Yetişkin, Egehan; Gülşah Şanlı Mohamed; 01. Izmir Institute of TechnologyCancer, which is the disease of our age, arises because of a very complex set of mechanisms. Especially with the proliferation of cancer disease and the increase in cancer-related deaths, it has a great impact on the development of drug studies by improving existing treatments or researching new treatment methods. Cantharidine and its analogs are natural anhydrides with an inhibitory effect on protein phosphatases. However, they are not included in cancer therapies due to their toxicity. In recent studies, it has been found that derivatives of cantharidin as isoindole-1,3-dione and its derivatives have anticancer effects. The main purpose of this study to investigate the effects of four different drugs, which are newly synthesized isoindole derivatives for use in cancer treatment, on different cancer cells. The cytotoxic effects of drugs on A549 (human lung adenocarcinoma), HeLa (human cervical carcinoma), PC3 (human prostate carcinoma), MCF-7 (human breast carcinoma), and Caco-2 (human colorectal carcinoma) cell lines were investigated by the MTT assay method, and the optimum incubation time was determined, then IC50 values were calculated. Then, the IC50 concentrations of the drugs were applied at 48 hours, which is the optimum incubation period, and apoptotic stages and cell cycle stages were compared using flow cytometry to understand whether the drugs have a suppressive function in cancer development. Scratch assay was performed to investigate the migration effect of drugs on cells. The results showed that the drugs are suppressive to cancer cells and can be used for therapeutic purposes in the future.
