Abstract

In the present study, a novel Schiff base derived from pyridine-4-carboxaldehyde and 4-aminobutan-1-ol was synthesized via a condensation reaction and purified by recrystallization from a DMF/water solvent system. The compound was characterized by IR, 1H-NMR, and 13C-NMR studies. The pharmacological potential of a synthesized compound was evaluated through cell viability and enzyme inhibition assays. The compound exhibited selective cytotoxicity toward MCF-7 breast cancer cells compared to non-tumorigenic MCF-10A cells, with IC₅₀ values of 6.5 mM and 21.8 mM, respectively. In enzyme inhibition studies, the compound showed dose-dependent inhibitory activity against HIV-1 reverse transcriptase, acetylcholinesterase, and α-glucosidase, with IC₅₀ values ranging from 11 to 14 mM. Notably, HIV-1 RT displayed higher sensitivity at lower concentrations. These findings suggest that the compound has multi-target pharmacological potential and may serve as a promising lead for further investigation. Molecular docking was employed to evaluate the binding behavior of a newly synthesized Compound I against HIV-1 reverse transcriptase, epidermal growth factor receptor, and acetylcholinesterase. Docking results revealed that Compound I exhibited moderate binding affinity toward all three targets, with a relative preference for acetylcholinesterase, as evidenced by favorable binding energies and key intermolecular interactions. Although its predicted affinities were lower than those of established reference inhibitors, Compound I demonstrated stable binding orientations and conserved interaction patterns within the active sites. These findings suggest that Compound I may serve as a promising lead scaffold for further structure-based optimization.

Özet

Bu çalışmada, piridin-4-karboksaldehit ve 4-aminobütan-1-ol'den türetilen yeni bir Schiff bazı, yoğunlaşma reaksiyonu yoluyla sentezlendi ve DMF/su çözücü sisteminden yeniden kristalleştirme yoluyla saflaştırıldı. Bileşik, IR, 1H-NMR ve 13C-NMR çalışmalarıyla karakterize edildi. Sentezlenen bileşiğin farmakolojik potansiyeli, hücre canlılığı ve enzim inhibisyonu testleri yoluyla değerlendirildi. Bileşik, tümör oluşturmayan MCF-10A hücrelerine kıyasla MCF-7 meme kanseri hücrelerine karşı seçici sitotoksisite gösterdi ve IC₅₀ değerleri sırasıyla 6,5 ​​mM ve 21,8 mM idi. Enzim inhibisyonu çalışmalarında, bileşik, HIV-1 ters transkriptaz, asetilkolinesteraz ve α-glukozidaza karşı doza bağımlı inhibitör aktivite gösterdi ve IC₅₀ değerleri 11 ila 14 mM arasında değişti. Özellikle, HIV-1 RT daha düşük konsantrasyonlarda daha yüksek hassasiyet gösterdi. Bu bulgular, bileşiğin çoklu hedefli farmakolojik potansiyele sahip olduğunu ve daha ileri araştırmalar için umut vadeden bir öncü bileşik olabileceğini düşündürmektedir. Yeni sentezlenen Bileşik I'in HIV-1 ters transkriptaz, epidermal büyüme faktörü reseptörü ve asetilkolinesteraz'a karşı bağlanma davranışını değerlendirmek için moleküler kenetleme kullanıldı. Kenetleme sonuçları, Bileşik I'in her üç hedefe karşı orta düzeyde bağlanma afinitesi gösterdiğini ve asetilkolinesteraz'a göre nispeten daha fazla bağlanma eğilimi sergilediğini ortaya koydu; bu durum, uygun bağlanma enerjileri ve temel moleküller arası etkileşimlerle kanıtlanmıştır. Tahmin edilen afiniteleri, yerleşik referans inhibitörlerininkinden daha düşük olmasına rağmen, Bileşik I, aktif bölgelerde kararlı bağlanma yönelimleri ve korunmuş etkileşim modelleri sergiledi. Bu bulgular, Bileşik I'in daha ileri yapı tabanlı optimizasyon için umut vadeden bir öncü iskelet görevi görebileceğini düşündürmektedir.
