Article Citation - WoS: 11Citation - Scopus: 11Synthesis and Biological Evaluation of Novel Aryloxyacetic Acid Hydrazide Derivatives as Anticancer Agents(Taylor & Francis inc, 2021) Senkardes, Sevil; Erdogan, Omer; Cevik, Ozge; Kucukguzel, S. GunizIn our continuing search for new anticancer agents, herein we report the synthesis of 2-(4-chloro-3-methylphenoxy)-N'-[(aryl)methylidene]acetohydrazides 3a-j and the evaluation of their anticancer activities on cell viability, morphological changes and caspase-3 activity in cancer cell lines including gastric cancer (MKN45), cervical cancer (HeLa) and breast cancer (MDA-MB-231) cells. 2-(4-chloro-3-methylphenoxy)-N'-[(4-phenylthiophen-2-yl)methylidene] acetohydrazide 3g presented the strongest growth inhibition against MKN45 gastric cancer cell lines with the IC50 value of 1.471 +/- 0.23 mu M. Moreover, compounds 3b and 3g showed high potency against the HeLa and MDA-MB-231 cell lines having IC50 in the range of 2.38-9.72 mu M. These compounds are more selective for the tested human cancer cells than for the mouse fibroblast cell line (NIH/3T3). As a result of the studies conducted in order to understand the molecular mechanism, compounds 3b and 3g enhanced expression of the caspase-3 pro-apoptotic proteins levels besides caspase-3 gene.Article Citation - WoS: 14Citation - Scopus: 12Synthesis of Some Novel Hydrazide-Hydrazones Derived From Etodolac as Potential Anti-Prostate Cancer Agents(Marmara Univ, 2022) Koc, Hande Cevher; Atlihan, Irem; Mega-Tiber, Pinar; Orun, Oya; Kucukguzel, S. Guniz; Tiber, Pinar Mega(R,S)-Etodolac [1,8-diethyl-1,3,4,9-tetrahydrapyrano(3,4-b)indole-1-acetic acid] is a nonsteroidal anti-inflammatory drug that contains carboxylic acid group with the structure of pyrano[3,4-h]indole. In this study, a series of novel (R,S)-Etodolac derivatives (3a-1) bearing hydrazide-hydrazone moiety were synthesized. The structures of these compounds were characterized by spectral (H-1-NMR and FT-IR analyses) methods. All synthesized compounds were screened for anticancer activity against androgen-independent prostate adenocarcinoma (PC-3, DU-145) and androgen-dependent prostate adenocarcinoma (LNCaP) cell lines by using WST-8 colorimetric method. This method was used for cell viability and cytotoxicity analysis. Compound 3b (SGK-720) [2-(1,8-diethyl-1,3,4,9-tetrahydropyrano[3,4-b]indole-1-yl)acetic acid[(2,6-dichlorophenyl)methylene]hydrazides] showed 10.36, 5.24, 15.53 mu M anticancer activity against PC3, DU145, LNCaP cancer cell lines, respectively. According to JC-1 mitochondrial membrane potential test and Annexin V/PI staining, 3b was found to have apoptotic effect on these cancer cells. It is concluded that compound 3b containing 2,6-dichloro substituents may be one of the candidate molecules to cope with prostate cancer.Review 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.Article Citation - WoS: 18Citation - Scopus: 20Design, Synthesis and Anticancer Activity Studies of Novel 4-Butylaminophenyl Hydrazide-Hydrazones as Apoptotic Inducers(Pergamon-elsevier Science Ltd, 2022) Han, M. Ihsan; Baysal, Ozge Deniz Yesil; Basaran, Guzide Satir; Sezer, Gulay; Telci, Dilek; Kucukguzel, S. Guniz; Yeşil Baysal, Özge DenizIn this study, a series of the novel Tetracaine derivatives bearing hydrazide-hydrazone moiety were designed, synthesized, and evaluated for anticancer activity. The structures of these compounds were characterized by spectral (H-1-C-13 NMR, FT-IR, and HR-MS analyses) methods. All synthesized compounds (2a-1) were screened for anticancer activity against human hepatocellular carcinoma (HepG2) and lung carcinoma (A549) cell lines. Against HepG2 and A549 cell lines, among the synthesized compounds, 4-(Butylamino)-N'-[(2,4-dichlorophenyl)methylidene]benzohydrazide (2i) demonstrated the most potent anticancer activity with IC50 values 28 and 7 mu M, respectively. Possible cytotoxic effects of compounds (2a-1) on both normal human lung fibroblast (MCR-5) and normal human dermal fibroblast (HDF) cell lines were assessed. Inhibition of anti-apoptotic protein Bax and Bcl-2 was investigated in HepG2 and A549 cells treated with compound 2i using qRT-PCR. Apoptosis was also detected by Annexin V studies. The flow cytometric analysis results showed that compound 2i treatment of HepG2 and A549 cells significantly increased apoptotic cell populations while decreasing viabilities in these carcinomas in a dose-dependent manner after 72 h of incubation.

Ihsan; Gurboga, Merve; Ozakpinar, Ozlem Bingol; Kucukguzel, S. Guniz; Güniz Küçükgüzel, Ş.; İhsan Han, M.In the present study, the various 28 hybrid molecules containing hydrazone and sulfonate moieties were synthesized and characterized by FTIR, H-1-NMR, C-13-NMR spectroscopy and LC-MS spectrometry, besides elemental analysis. The compounds were evaluated for their antiproliferative effects against six cancer cell lines, namely A549 (non-small cell lung cancer), MCF-7 (breast cancer), HT-29 (colorectal adenocarcinoma cancer), PC-3 (androgen-independent prostate adenocarcinoma), Hep3B (hepatocellular carcinoma cancer), and HeLa (epitheloid cervix carcinoma cancer). Among all the target compounds, compounds 4g and 4h exhibited more promising effects on MCF-7 cell lines (IC50 = 17.8 mu M and 21.2 mu M, respectively) with high selectivity. Further mechanistic studies proposed that compounds 4g and 4h induced apoptosis is mediated through the intrinsic apoptotic pathway with changes in mitochondrial membrane potential by finally activating caspase-9 and caspase-3. The results have been encouraging enough to merit further investigation. [GRAPHICS] .
