Publication Metadata only Synthesis of Diflunisal Thiazolidinones as Anticancer Agents(BENTHAM SCIENCE PUBL LTD, 2016) ŞENER, AZİZE; Senkardes, Sevil; Ozakpinar, Ozlem B.; Ozsavci, Derya; Sener, Azize; Cevik, Ozge; Kucukguzel, S. GunizA series of diflunisal 4-thiazolidinones were synthesized. Some selected compounds were determined at one dose towards the full panel of 60 human cancer cell lines by National Cancer Institute. 2',4'-Difluoro-4-hydroxy-N-[4-oxo-2-(thiophen-2-yl)-1,3-thiazolidin-3-yl]biphenyl-3-carboxamide (4a) demonstrated the most marked effect on K-562 cancer cell line with 58.59 % growth inhibition at 10 mu M. Compound 4a was evaluated in vitro using the MTT colorimetric method against human leukemia cell line K-562 and mouse embryonic fibroblasts cell line NIH-3T3 at different doses for cell viability and growth inhibition. Compound 4a exhibited anticancer activity with IC50 value of 5.2 mu M against K-562 cells and did not display cytotoxicity towards NIH-3T3 cells compared with diflunisal. In addition, this compound could be an interesting prototype as an antiproliferative agent.Publication Metadata only Synthesis and Anticancer Activity of Some Novel Tolmetin Thiosemicarbazides(MARMARA UNIV, FAC PHARMACY, 2015) ÖZSAVCI, DERYA; Dadas, Yakup; Coskun, Goknil Pelin; Bingol-Akpinar, Ozlem; Ozsavci, Derya; Kucukguzel, S. GunizA novel series of new ten tolmetin hydrazide derivatives, N-Alkyl/Arylsubstituted-2-{[1-methyl-5-(4-methylbenzoyl)-1H- pyrrol-2-yl]acetyl}hydrazinecarbothioamides [4a-j] have been synthesized in this study. The structures of the new compounds were determined by spectral (FT-IR, H-1-NMR, C-13-NMR and 2D-NMR) methods and their purity were proven by elemental analysis and TLC. Tolmetin [1] and N-(4-fluorophenyl)-2-{[1-methyl-5-(4-methylbenzoyl)-1H-pyrrol-2- yl] acetyl}hydrazinecarbothioamide [4d] were evaluated for in vitro using the MTT colorimetric method for anticancer activity. Androjen-independed human prostate cancer cell line PC-3 (ATCC, CRL-1435), human colon cancer cell lines HCT-116 (ATCC, CCL-247) and HT-29 (ATCC, HTB-38) were used in this study. Compound 4d exhibited anticancer activity against PC-3 whereas Tolmetin showed minor activity comparing to compound 4d.Publication Metadata only Synthesis, Cytotoxicity, and Pro-Apoptosis Activity of Etodolac Hydrazide Derivatives as Anticancer Agents(WILEY-V C H VERLAG GMBH, 2013) ŞENER, AZİZE; Cikla, Pelin; Ozsavci, Derya; Bingol-Ozakpinar, Ozlem; Sener, Azize; Cevik, Ozge; Ozbas-Turan, Suna; Akbuga, Julide; Sahin, Fikrettin; Kucukguzel, S. GunizEtodolac hydrazide and a novel series of etodolac hydrazide-hydrazones 315 and etodolac 4-thiazolidinones 1626 were synthesized in this study. The structures of the new compounds were determined by spectral (FT-IR, 1H NMR, 13C NMR, HREI-MS) methods. Some selected compounds were determined at one dose toward the full panel of 60 human cancer cell lines by the National Cancer Institute (NCI, Bethesda, USA). 2-(1,8-Diethyl-1,3,4,9-tetrahydropyrano[3,4-b]indole-1-yl)acetic acid[(4-chlorophenyl)methylene]hydrazide 9 demonstrated the most marked effect on the prostate cancer cell line PC-3, with 58.24% growth inhibition at 105M (10 mu M). Using the MTT colorimetric method, compound 9 was evaluated in vitro against the prostate cell line PC-3 and the rat fibroblast cell line L-929, for cell viability and growth inhibition at different doses. Compound 9 exhibited anticancer activity with an IC50 value of 54 mu M (22.842 mu g/mL) against the PC-3 cells and did not display any cytotoxicity toward the L-929 rat fibroblasts, compared to etodolac. In addition, this compound was evaluated for caspase-3 and Bcl-2 activation in the apoptosis pathway, which plays a key role in the treatment of cancer.
