Abstrakt: Objective: This study aimed to design and evaluate the efficacy of pyrrolidone derivatives as potential therapeutic agents against diffuse large B-cell lymphoma (DLBCL), a common and heterogeneous malignancy of the adult lymphohematopoietic system. Given the limitations of current therapies, there is a pressing need to develop new and effective drugs for DLBCL treatment.
Methods: A series of pyrrolidone derivatives were synthesized, and their antitumor activities were assessed, particularly against DLBCL cell lines. Structure-activity relationship (SAR) analysis was conducted to identify key structural components essential for activity. The most promising compound, referred to as compound 7, was selected for further mechanistic studies. The expression levels of relevant mRNA and protein were detected by RT-qPCR and Western blotting, and the expression of mitochondrial membrane potential and ROS was detected using flow cytometry for further assessment of cell cycle arrest and apoptosis.
Results: The compound 7 exhibited good antitumor activity among the synthesized derivatives, specifically in DLBCL cell lines. SAR analysis highlighted the critical role of α, β-unsaturated ketones in the antitumor efficacy of these compounds. Mechanistically, compound 7 was found to induce significant DNA damage, trigger an inflammatory response, cause mitochondrial dysfunction, and disrupt cell cycle progression, ultimately leading to apoptosis of DLBCL cells.
Conclusion: The compound 7 has good antitumor activity and can induce multiple cellular mechanisms leading to cancer cell death. These findings warrant further investigation of the compound 7 as a potential therapeutic agent for DLBCL.
