In this study, 4-[5-(4-hydroxyphenyl)-3-aryl-4,5-dihydro-1H-pyrazol-1-yl]benzenesulfonamide derivatives (8-14) were synthesized for the first time by microwave irradiation and their chemical structures were confirmed by ¹H NMR, ¹³C NMR and HRMS. Cytotoxic activities and inhibitory effects on carbonic anhydrase I and II isoenzymes of the compounds were investigated. The compounds 9 (PSE = 4.2), 12 (PSE = 4.1) and 13 (PSE = 3.9) with the highest potency selectivity expression (PSE) values in cytotoxicity experiments and the compounds 13 (Ki = 3.73 ± 0.91 nM toward hCA I) and 14 (Ki = 3.85 ± 0.57 nM toward hCA II) with the lowest Ki values in CA inhibition studies can be considered as leader compounds for further studies.

Aim: Parkinson’s disease (PD) is the second most widespread neurodegenerative disease. This study, it was aimed to investigate the effect of methanol extract obtained from Capparis spinosa L. fruits, which are known to have important bioactive components, on in-vitro experimental PD model. Material and Method: After collecting Capparis spinosa L. fruits from Alanya/Antalya, methanol extract was prepared by drying and grinding. SH-SY5Y cells grown in flasks were transferred to 96 well plates and were incubated until 80% cell density was reached. Different doses of methanol extract were applied to the cells 30 minutes before the PD model was formed. For the PD model, SH-SY5Y cells were exposed to 200 µM 6-OHDA for 24 hours. MTT analysis was performed to assess the viability of SH-SY5Y cells at the end of the 24-hour period. TOS, TAC, and IL-17A levels in the cell medium were determined using the ELISA method. Expression of TNFα and α-synuclein was defined using the immunohistochemical method. Results: Cell viability was found to be higher in all treatment groups than in the 6-OHDA group. Moderate levels of TNFα and α-synuclein positivity were observed in the 1500 µg/ml methanol extract group. It was determined that TOS and TAC levels change depending on the dose. It has been determined that the level of IL-17A decreases at low doses. Statistical significance was found between the groups. Conclusion: When the findings were examined, it was determined that the methanol extract obtained from Capparis spinosa L. fruits reduced oxidative stress and IL-17A levels at low doses and provided a neuroprotective effect by increasing the antioxidant capacity.

Anticancer Potential of Watermelon Seed Extracts Against Lung and Breast Cancer Cell Lines Karpuz Çekirdeği Ekstrelerinin Akciğer ve Meme Kanseri Hücre Hatlarına Karşı Antikanser Potansiyeli Running Title: Anticancer Potential of Watermelon Seed Abstract Objective: The aim of the study is to evaluate the anticancer potential of watermelon seed extracts against lung and breast cancer cell lines. Methods: A549 lung cancer and MCF-7 breast cancer cell lines were used. The cells were treated with doses ranging from 0.1 to 1000 µg/mL of KI and KD extracts from watermelon seeds, starting when the cell density reached 80%. Viability was assessed using the MTT assay. Results: For the A549 lung cell line, the KI extract demonstrated significant anticancer activity at doses of 10, 100, and 1000 µg/mL, with the 1000 µg/mL dose being the most effective against lung cancer cells. Similarly, the KD extract showed efficacy across all doses tested, with the seed peel being effective at lower doses compared to the seed. In the MCF-7 breast cell line, both KI and KD extracts exhibited dose-dependent anticancer effects, with significant reductions in viability observed at all doses compared to the control group. Conclusion: Interestingly, the seed and seed shell showed selective effectiveness against breast and lung cancer, indicating a dose-dependent and selective anticancer effect. Overall, these findings suggest the potential of watermelon seed extracts as promising anticancer agents with selective efficacy against different cancer types. Keywords: Watermelon, anticancer, A549 lung cancer cell, MCF-7 breast cancer cell ÖZ Amaç: Çalışmanın amacı, karpuz çekirdeği ekstrelerinin akciğer ve meme kanseri hücre hatlarına karşı antikanser potansiyelini değerlendirmektir. Yöntemler: A549 akciğer kanseri ve MCF-7 meme kanseri hücre hatları kullanılmıştır. Hücreler, yoğunlukları %80'e ulaştığında, karpuz çekirdeğinden hazırlanan KI ve KD ekstreleri ile 0.1 ila 1000 µg/mL doz aralığında muamele edilmiştir. Canlılık, MTT testi kullanılarak değerlendirilmiştir. Bulgular: A549 akciğer hücre hattı için KI ekstresi, 10, 100 ve 1000 µg/mL dozlarında önemli antikanser aktivite göstermiş, 1000 µg/mL dozu akciğer kanseri hücrelerine karşı en etkili olarak bulunmuştur. Benzer şekilde, KD ekstresi, test edilen tüm dozlarda etkili olmuş ve tohum kabuğunun, tohuma göre daha düşük dozlarda etkili olduğu görülmüştür. MCF-7 meme hücre hattında, hem KI hem de KD ekstreleri doza bağlı antikanser etki sergilemiş ve kontrol grubuna kıyasla tüm dozlarda önemli düzeyde canlılık azalması gözlenmiştir. Sonuç: Karpuz çekirdeği ve kabuğu meme ve akciğer kanserine karşı seçici etkinlik göstermiş, bu da doza bağlı ve seçici bir antikanser etkiyi işaret etmektedir. Genel olarak, bu bulgular, karpuz çekirdeği ekstrelerinin farklı kanser türlerine karşı seçici etkili ve umut vaat edici antikanser ajanlar olarak potansiyelini göstermektedir.
