Introduction: Cyclin-dependent kinase 6 (CDK6) became a valid target for breast cancer therapy over the past decades. Binding of this enzyme to E2F transcription factors eventually controls cell division. Therefore, inhibition of this enzyme becomes vital in apoptosis of the breast cancer cells. Besides, indole-thiazolidinediones prove to be a valuable asset in breast cancer therapy. The wide range of findings in this study area has encouraged us to design and synthesize novel indole-thiazolidinedione derivatives (9-24) (1, 2). Materials and Methods: For the synthesis of the derivatives 9-24, mixture of appropriate indole-3-carboxaldehyde, phenacyl-methyl-thiazolidine-2,4-dione and diethanolamine in MeOH was refluxed until starting materials were consumed (determined by TLC, purified with cc). Aftersynthesizing these derivatives, their anticancer activity was probed on MCF-7 cell lines and their gene suppressing profiles were elucidated. For the thorough evaluation of their mechanism of action involving CDK6 pathway, docking of these compounds and standard Palbociclib was made with corresponding enzyme using AutoDock Vina (3). Moreover, druglikeness of indole-thiazolidinedione derivatives were calculated with SwissADME (4) and compared to the commercial anticancer drugs. Results: According to biological activity assays; compounds 10, 15, and 18 were found to possess favorable cytotoxicity on MCF-7 cells. Comparing to other genes, these compounds inhibited gene expression of CDK6 remarkably. Regarding docking analysis, 15 and 18 possessed higher affinity with better binding interactions relative to that of compound 10. Conclusions: With higher gene suppression characteristics, and low IC50 values, compounds 15 and 18 were highlighted as possible candidates for the upcoming design studies of CDK6 inhibitors. These compounds also have had better interaction profiles with the related enzyme. Acknowledgements The work was supported by Ankara University Research Grant under grant number: 19B0237003.

Novel ferrocenyl pyrazoles inhibit breast cancer cell viability via induction of apoptosis and inhibition of PI3K/Akt and ERK1/2 signaling
Atmaca, Harika; Ozkan, Ayse Nur; Zora, Metin (2017-02-01)
Despite the advances in early detection and targeted therapies, chemotherapy is still of vital importance in breast cancer treatment. However, development of drug resistance and serious side effects limits their usage. Thus, there is an urgent need for safer and more effective agents against breast cancer. We have previously described the synthesis of a number of pyrazole derivatives, and in the current study, we have investigated the effects of two different ferrocenyl pyrazole (FP) derivates, 5-ferrocenyl...
Multidrug Resistance Mediated by MRP1 Gene Overexpression in Breast Cancer Patients
Abaan, Ogan Demir; Mutlu, Pelin; Baran, Yusuf; Atalay, Can; Gündüz, Ufuk (2009-01-01)
Multidrug resistance (MDR) is a serious handicap towards the effective treatment of breast cancer patients. One of the most prevalent MDR mechanisms is through the overexpression of genes coding the proteins called Multidrug Resistance-associated Proteins (MRPs). The aim of this study was to investigate the expression of MRP1 in tumor tissues from breast cancer patients. In this study, a semi-quantitative RT-PCR approach was utilized. Our results suggest that MRP1 overexpression can mediate MDR in patients....

Akpınar, Yeliz; Özçubukçu, Salih; Department of Chemistry (2017)
Over the past decade, there has been an increasing interest in using nanotechnology for cancer therapy. Magnetic-based systems containing magnetic nanoparticles have gained popularity because of their unique ability to be used in magnetic resonance imaging, magnetic targeting, drug carrying and hyperthermia. The last one represents a novel therapeutic concept to cancer treatmentIn biomedical and clinical applications the most commonly used magnetic nanomaterials are the iron oxide nanoparticles. Current pro...
Magnetic Half Generation PAMAM Dendrimeric Nanoparticles for Targeting Delivery of Gemcitabine
Maryam, Parsian; Mutlu, Pelin; Yalçın Azarkan, Serap; Tezcaner, Ayşen; Gündüz, Ufuk (2015-06-09)
Antitumor activity of Gemcitabine, a nucleoside analogue, has been reported in a variety of human tumors, including breast cancer in both experimental and clinical studies. Conventional chemotherapeutic agents are unspecifically distributed all over the body where they affect both cancerous and normal cells. They cause major systemic toxicities and drug resistance, which also restricts drugs therapeutic efficacy. Recent advances in nanotechnology have explored new targeting strategies for enhancing intra-tu...
Amitriptyline; a systems biomedicine-oriented repositioned drug candidate for breast cancer
Taş, Fadime Dilşad; Okutan, Keziban; Ceylan, Tuğba; Özkaya, Ömer Faruk; Aydın, Büşra (Orta Doğu Teknik Üniversitesi Enformatik Enstitüsü; 2022-10)
Introduction: Breast cancer (BRCA) is a disease where the growth of breast cells is out of control. According to WHO’s latest cancer statistics, the BRCA is the world’s most prevalent cancer. In clinic, there are possible treatments that target cancer cells such as chemotherapy, radiation, or hormone therapies. However, these treatments have long-term side effects that can occur even multiple years after the treatment which may lead to even notorious consequences. Methods: Transcriptome-level BRCA gene expr...
