The structure of novel heterocyclic compounds was elucidated by using some spectroscopic techniques (organic elemental analysis, fourier transform infrared spectroscopy, proton/carbon nuclear magnetic resonance spectroscopy, scanning electron microscopy and energy dispersive X-ray image, and molar conductance measurement). The antiproliferative activity of novel heterocyclic thiosemicarbazone compounds using CVDK-8 cell viability assay. The viability assay was examined against A549 human non-small cell lung cancer cell line. All heterocyclic thiosemicarbazone compounds exhibited varying degrees of dose-dependent cytotoxic activity against A549 NSCLC cells. The results showed that the pyridine-based heterocyclic compound (Hb3) was the most potent antiproliferative agent, demonstrating a dose-dependent reduction in cell viability at concentrations of 50 µg/mL and higher.</dc:description><dc:publisher>SAGE Publications Ltd</dc:publisher><dc:date>2026</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/bayburt/11344</dc:identifier><dc:identifier>https://doi.org/10.1177/10241221261483996</dc:identifier><dc:identifier>1024-1221</dc:identifier><dc:language>en</dc:language><dc:relation>Main Group Chemistry</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/11344</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
