Article Citation - WoS: 2Citation - Scopus: 1Synthesis and Investigation of Cytotoxic Effects of Compounds Derived From Flurbiprofen(Elsevier, 2023) Gokoglan, Ecem; Dere, Damla; Bedir, Ipek; Yelekci, Kemal; Telci, Dilek; Kucukguzel, S. GunizNew flurbiprofen derivatives containing 1,2,4-triazoline-5-thione (4) and thioethers (5a-r) were synthesized in this study. The structures of synthesized compounds were characterized by spectral methods (FT-IR, 1H NMR, 13C NMR) and 19F NMR (only compound 5l), besides elemental analysis. In addition, molecular binding of these compounds to the human methionine aminopeptidase 2 enzyme was performed using AutoDock 4.2, the software product of the research, computationally. All synthesized compounds were evaluated for cytotoxic effect against MDA-MB231 triple-negative breast cancer cell line by using WST-1 Cell Viability and Proliferation assay. Doxorubicin is in the anthracycline class and is an antineoplastic agent. It is used to provide regression in common neoplastic conditions such as breast carcinoma. Due to the cardiovascular side effects of doxorubicin, a combination study was conducted with the (& PLUSMN;)(R,S)-3-{1-[2-fluoro-(1,1 & PRIME;-biphenyl)-4-yl]ethyl}-4-methyl-5-{[2(trifluoromethyl)benzyl]thio}-4H-1,2,4-triazole (5l) with promising cytotoxic effects. As a result of the combination, it was shown as 7% MDA-MB231 cell viability. Therefore, based on the evaluations, a better cytotoxic effect was achieved with the 5l combination depending on the low dose of doxorubicin.Article Citation - WoS: 9Citation - Scopus: 10Synthesis and Molecular Modeling of Metap2 of Thiosemicarbazides, 1,2,4-Triazoles, Thioethers Derived From (s)-Naproxen as Possible Breast Cancer Agents(Elsevier, 2022) Birgul, Kaan; Uba, Abdullah Ibrahim; Cuhadar, Ozan; Sevinc, Sevgi Kocyigit; Tiryaki, Selen; Tiber, Pinar Mega; Kucukguzel, S. Guniz; Güniz Küçükgüzel, Ş.New thiosemicarbazides (3, 5-6), 1,2,4-triazoles (14-15) and thioethers (22-68) from derived (S)-Naproxen were synthesized in this study. The structure of these compounds were elucidated by spectral (FT-IR, H-1 NMR, C-13 NMR) methods, besides elemental analysis and TLC. The molecular binding of the compounds on MetAP-2 was performed. Anticancer effects of the synthesized compounds were studied by using MTT assay method on MCF-7 (includes oestrogene and progesterone receptors) and MDA-MB-231 (lacks estrogen and progesterone receptors) adenocarcinoma cell lines at 0, 10, 25, 50, 75 and 100 mu M concentrations for 24 h. The IC(50 )values of novel (S)-Naproxen derivatives were determined between from 5 to 100 mu M on MCF-7 breast cancer cell line and MDA-MB-231 cell lines. The apoptotic activity of selected compounds 22 and 42 were first analyzed by Annexin V staining using Tali Image-Based Cytometer. Mitochondrial membrane potential changes determined in fluorescence plate reader following JC-1 stain for compounds 22 and 42 in MCF-7 and MDA-MB-231 cells. The effect of these compounds on the cell viability 4T1 mouse mammary tumor cell line was tested at 1 to 5 times of calculated IC50 value (IC(50)x1, IC(50)x2, IC(50)x3, IC(50)x4, and IC(50)x5). Next in order to determine the toxicity of the combination of compound 51 and Docetaxel, WST-1 cell viability and proliferation assay was performed with 4T1. (C) 2022 Elsevier B.V.
