Abstract

According to global estimates, there are 2.3 million new cases and 1.8 million fatalities due to lung cancer each year. Despite recent progress in diagnosis and treatment, persistent challenges highlight the urgent need for novel therapeutics and innovative approaches to combat lung cancer effectively. Accordingly, in the present study, we aimed to investigate the anticancer properties of potential inhibitors of HIF-1α, compound 7a and 7b. In the study, HTB-54 and BEAS-2B cell lines were used. MTT cell viability experiments were performed to determine the effect of newly synthesized HIF inhibitors 7a and 7b on cell viability under normoxic and hypoxic conditions. Quantitative expression levels of HIF1A were determined by real-time PCR approach. While the half maximum inhibitory concentration (IC50) of compound 7a in HTB-54 cells was 10.37 µM under normoxic conditions, it was found to be 10.63 µM under hypoxic conditions. The IC50 value of another HIF inhibitor 7b in HTB-54 cells was found to be 8.80 µM under normoxic conditions and 9.54 µM under hypoxic conditions. The expression level of HIF1A was found to be lower in cells exposed to compounds 7a and 7b under hypoxia compared to the control group. Conversely, in normoxia, HIF1A expression level in cells exposed to compound 7a increased 6.5-fold (p<0.0001) compared to the control group, while it was found to increase approximately 9-fold (p<0.0001) when exposed to 7b. Consequently, both compound 7a and 7b holds great promise for future therapeutic interventions to lung cancer.

Özet

Küresel tahminlere göre her yıl akciğer kanseri nedeniyle 2,3 milyon yeni vaka ve 1,8 milyon ölüm yaşanmaktadır. Tanı ve tedavideki son gelişmelere rağmen devam eden zorluklar, akciğer kanseriyle etkili bir şekilde mücadele etmek için yeni tedavi yöntemlerine ve yenilikçi yaklaşımlara olan acil ihtiyacı vurgulamaktadır. Dolayısıyla, bu çalışmada HIF-1α'nın potansiyel inhibitörleri olan 7a ve 7b bileşiklerinin antikanser özelliklerinin araştırılması amaçlanmıştır. Çalışmada HTB-54 ve BEAS-2B hücre hatları kullanılmıştır. Yeni sentezlenen HIF inhibitörleri 7a ve 7b'nin normoksik ve hipoksik koşullar altında hücre canlılığı üzerindeki etkisini belirlemek için MTT hücre canlılığı deneyleri yapılmıştır. HIF1A'nın kantitatif ekspresyon seviyeleri, Real-Time PCR yöntemi ile belirlenmiştir. HTB-54 hücrelerinde 7a bileşiğinin yarı maksimum inhibitör konsantrasyonu (IC50) normoksik koşullar altında 10,37 µM iken hipoksik koşullar altında 10.63 µM olarak bulunmuştur. HTB-54 hücrelerindeki diğer bir HIF inhibitörü 7b'nin IC50 değeri normoksik koşullar altında 8,80 µM, hipoksik koşullar altında ise 9.54 µM olarak bulunmuştur. Hipoksik koşullarda, 7a ve 7b bileşikleri ile maruz bırakılan hücrelerde HIF1A ekspresyon düzeyinin kontrol grubuna göre daha düşük olduğu gösterilmiştir. Normoksi koşullarda ise HIF1A ekspresyon düzeyi 7a bileşiği ile maruz bırakılan hücrelerde kontrol grubuna göre 6,5 kat (p<0.0001), 7b'ye maruz kaldığında ise yaklaşık 9 kat (p<0.0001) arttığı bulunmuştur. Sonuç olarak hem 7a hem de 7b bileşikleri akciğer kanserine yönelik gelecekteki terapötik girişimler için büyük umut vaat etmektedir.
