This study describes the synthesis and characterization of a series of novel hydrazide-hydrazone derivatives containing a 1,2,4-triazole ring. The compounds were characterized using various spectroscopic techniques, such as FT-IR, 1H-NMR, 13C-NMR, HRMS, and elemental analysis. The antiproliferative activity of the synthesized compounds was evaluated against a panel of human cancer cell lines (HCT-116, HepG-2, KLN205, LTPA, U138, and SW620) and healthy cell lines (HSkMC and iPSCs). Among the compounds tested, compounds 4, 5p, 5r, and 5s showed the highest effectiveness in inhibiting the growth of cancer cells with Bcl-xL inhibitory concentration (IC50) values. These compounds further demonstrated selective cytotoxicity against the Bcl-xL-dependent lymphoma cell line (DBs). Molecular docking studies were also performed to investigate the potential binding interactions of compounds 4, 5p, 5r, and 5s with the active site of Bcl-xL (PDB ID: 7LH7, 1.4 Å). Mechanistic studies revealed that compounds 4, 5r, and 5s induced apoptosis predominantly through the intrinsic mitochondrial pathway, while compound 5p exhibited a distinct cell cycle arrest profile, impacting both the S and G2/M phases. Western blot analysis suggested that these compounds may downregulate cyclin expression, thereby blocking its association with Bcl-xL. Overall, these results demonstrate the potential of these novel hydrazide-hydrazone derivatives as anticancer agents with activity comparable or superior to doxorubicin and 5-fluorouracil.
