Article Citation - WoS: 3Citation - Scopus: 3A Novel Petox-Based Nanogel Targeting Prostate Cancer Cells for Drug Delivery(Wiley-v C H verlag Gmbh, 2024) Gulyuz, Sevgi; Sessevmez, Melike; Ukuser, Gokcen; Khalily, Melek Parlak; Tiryaki, Selen; Sipahioglu, Tarik; Yilmaz, OzgurThis study focuses on creating a specialized nanogel for targeted drug delivery in cancer treatment, specifically targeting prostate cancer. This nanogel (referred to as SGK 636/Peptide 563/PEtOx nanogel) is created using hydrophilic poly(2-ethyl-2-oxazoline) (PEtOx) through a combination of living/cationic ring-opening polymerization (CROP) and alkyne-azide cycloaddition (CuAAC) "click" chemical reactions. A fluorescent probe (BODIPY) is also conjugated with the nanogel to monitor drug delivery. The characterizations through 1H-NMR, and FT-IR, SEM, TEM, and DLS confirm the successful production of uniform, and spherical nanogels with controllable sizes (100 to 296 nm) and stability in physiological conditions. The biocompatibility of nanogels is evaluated using MTT cytotoxicity assays, revealing dose-dependent cytotoxicity. Drug-loaded nanogels exhibited significantly higher cytotoxicity against cancer cells in vitro compared to drug-free nanogels. Targeting efficiency is examined using both peptide-conjugated and peptide-free nanogels, with the intracellular uptake of peptide 563-conjugated nanogels by tumor cells being 60-fold higher than that of nanogels without the peptide. The findings suggest that the prepared nanogel holds great potential for various drug delivery applications due to its ease of synthesis, tunable functionality, non-toxicity, and enhanced intracellular uptake in the tumor region. This study emphisizes an innovative PEtOx-based nanogel tailored for targeted drug delivery in prostate cancer. Developed using click chemistry, a valuable technique for chemical synthesis, it exhibits consistent nanogel formation with customizable sizes. In vitro, drug-loaded nanogel exhibits potent cytotoxicity against cancer cells. Notably, peptide-conjugated nanogels significantly boost tumor cell uptake, showcasing promising promising potential for effective cancer drug delivey.imageReview Citation - WoS: 15Citation - Scopus: 11Thioethers: an Overview(Bentham Science Publ Ltd, 2022) Han, M. Ihsan; Kucukguzel, S. GunizSpreading rapidly in recent years, cancer has become one of the causes of the highest mortality rates after cardiovascular diseases. The reason for cancer development is still not clearly understood despite enormous research activities in this area. Scientists are now working on the biology of cancer, especially on the root cause of cancer development. The aim is to treat the cancer disease and thus cure the patients. The continuing efforts for the development of novel molecules as potential anti-cancer agents are essential for this purpose. The main aim of this review was to present a survey on the medicinal chemistry of thioethers and provide practical data on their cytotoxicities against various cancer cell lines. The research articles published between 2001-2020 were consulted to prepare this review article; however, patent literature has not been included. The thioether-containing heterocyclic compounds may emerge as a new class of potent and effective anti-cancer agents in the future.
