Article Anticancer Properties of Newly Synthesized Pyrrole Derivatives as Potential Tyrosine Kinase Inhibitors(Wiley, 2026) Kaya, Meltem; Kara, Yunus; Sanli-Mohamed, GulsahThe anticancer activity of a series of newly synthesized pyrrole derivatives was systematically evaluated in HeLa cervical cancer cells, focusing on their potential as tyrosine kinase inhibitors and modulators of the mTOR signaling pathway. This study builds on our previous synthetic work by investigating the biological effects of seven structurally characterized compounds (d1-d7). Among them, compounds d1 and d3 exhibited the most potent cytotoxicity, with IC50 values of 140.6 mu M and 366.4 mu M, respectively, after 48 h of treatment. Both compounds significantly impaired cell cycle progression-d1 induced S-phase arrest, while d3 caused G1-phase arrest-and markedly suppressed cell migration in wound healing assays. Mechanistically, these effects were accompanied by reduced phosphorylation of p70S6K (Thr389, Ser421/424) and increased p-4EBP1, indicating inhibition of mTORC1 signaling. These findings suggest that d1 and d3 are promising lead compounds with dual antiproliferative and anti-migratory activity in cervical cancer, mediated through modulation of the PI3K/Akt/mTOR axis.Article Citation - WoS: 3Citation - Scopus: 3Synthesis, Cytotoxicity, and Antibacterial Studies of 2,4,5,6-Substituted Hexahydro-1h(Wiley, 2023) Yetişkin, Egehan; Gündoğdu, Özlem; Mete, Derya; Celebioglu, Neslihan; Kara, Yunus; Şanlı-Mohamed, GulsahIn this study, synthesis of novel isoindole-1,3-dione analogues bearig halo, hydroxy, and acetoxy groups at the position 4,5,6 of the bicyclic imide ring was performed to examine their potential anticancer effects against some cell lines. A multistep chemical pathway was used to synthesize the derivatives. The cytotoxic effect of trisubstituted isoindole derivatives were evaluated by determining cellular viability using the MTT assay against A549, PC-3, HeLa, Caco-2, and MCF-7 cell lines. The C-2 selective ring-opening products were obtained from the ring-opening reaction of 5-alkyl/aryl-2-hydroxyhexahydro-4H-oxireno[2,3-e]isoindole-4,6(5H)-diones with nucleophiles such as chloride (Cl-) and bromide (Br-) ions. In addition, the ring-opening products halodiols were converted to their related acetates. The anticancer activity of synthesized isoindole-1,3-dione derivatives was investigated against HeLa, A549, MCF-7, PC3, and Caco-2 cells in vitro and resulted in varies cytotoxic effect depend on the group attached to the isoindole molecule. Furthermore, the evaluation of the antimicrobial action of trisubstituted isoindole derivatives against Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria was assessed and found out selective inhibition of the both bacterial growth via different trisubstituted isoindole derivatives. The results of this work encourage further research on the potential utilization of trisubstituted isoindole derivatives as cytotoxic and antimicrobial agents.
