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] .

Synthesis and Biological Evaluation of New 4-Thiazolidinone Derivatives of Flurbiprofen
(Acg Publications, 2023) Küçükgüzel, Şükriye Güniz; Senkardes, Sevil; Gurboga, Merve; Ozakpinar, Ozlem Bingol; Kucukguzel, S. Guniz; Eczacılık Meslek Bilimleri Bölümü
In this study, the synthesis and characterization of 2-(2-fluorobiphenyl-4-yl)-N '-[(substituted methylene]propanehydrazides (3a-s) and 2-(2-fluoro-[1,1'-biphenyl]-4-yl)-N-(5-methyl-2-(substituted aryl)-4oxothiazolidin-3-yl)propanamides (4a-s) are described and also the antiproliferative effect of the compounds on HT 29, HeLa, A549 and MCF-7 cancer cell lines is investigated. Additionally, mouse embryonic fibroblast cells NIH3T3 were also evaluated to determine the selectivity. The results showed that the identified compounds did not cause any toxicity against NIH3T3 cell line. Moreover, N-(2-(3,5-Bis(trifluoromethyl)phenyl)-5-methyl-4-oxothiazolidin-3-yl)-2-(2-fluoro-[1,1'-biphenyl]-4-yl)propanamide (4h) had the most growth inhibitory effect (55.97% inhibition) on HT-29 colorectal adenocarcinoma cell line. The results obtained from the study show that the compound 4h, which has no cytotoxic effect on normal cells, may be an alternative in the treatment of colon cancer.

Başlangıç maddesi olarak parasetamol kullanılarak bazı yeni triazol içeren asetamid türevleri 9-20 sentezlendi ve yapıları FTIR, NMR (1H and 13C) ve kütle spektral verileri ile karakterize edildi. Beş insan kanser hücre hattına (akciğer kanseri A549, kronik miyelojenöz lösemi K562, meme kanseri MCF-7, prostat kanseri PC-3, nöroblastoma SH-SY5Y hücre hatları) karşı sentezlenen tüm moleküllerin in vitro sitotoksik aktiviteleri incelendi ve ayrıca seçiciliği tanımlamak için fare embriyonik fibroblast hücreleri (NIH/3T3) üzerinde sitotoksik etkileri MTT yöntemiyle test edildi. Ek olarak, on iki hedef bileşik 9-20, mPGES-1 ve COX-1/2 inhibe edici etkileri açısından tarandı. Sentezlenen bileşiklerin hiçbiri hem kanser hücrelerine hem de mPGES-1 ve COX-1/2 enzimlerine karşı anlamlı bir inhibisyon göstermezken, sağlıklı hücrelere karşı da sitotoksik olmadıkları belirlendi. Son olarak yeni sentezlenen bileşiklerin ADMET özellikleri in siliko yöntemler kullanılarak tahmin edildi.
