Synthesis and Anticancer Activity Evaluation of New 5-((5-Nitrofuran-2-yl)allylidene)-2-thioxo-4-thiazolidinones

Area of Science:

• Medicinal Chemistry
• Oncology
• Molecular Biology

Background:

• Cancer remains a significant global health challenge, driving research into novel therapeutic compounds.
• 4-Thiazolidinones are a class of compounds with established therapeutic applications, now being explored for anticancer potential.
• Several 4-thiazolidinone derivatives have advanced to clinical trials for antitumor activity.

Purpose of the Study:

• To synthesize and evaluate fifteen new 4-thiazolidinone derivatives as potential anticancer agents.
• To assess the efficacy of these compounds against human breast cancer cell lines (MCF-7 and MDA-MB-231).
• To elucidate the mechanism of action, focusing on apoptosis induction and mitochondrial function.

Main Methods:

• MTT cytotoxicity assay to determine compound activity.
• Flow cytometry using Annexin V/propidium iodide to assess apoptosis.
• JC-1 dye analysis via flow cytometry to evaluate mitochondrial membrane potential.
• ELISA to quantify proapoptotic proteins (Bax, cytochrome C).
• Fluorescent microscopy to detect reactive oxygen species (ROS) generation.

Main Results:

• Three of the fifteen synthesized 4-thiazolidinone derivatives exhibited significant cytotoxicity against MCF-7 and MDA-MB-231 cells.
• The active compounds were found to induce apoptosis in breast cancer cells.
• Mitochondrial membrane potential was affected, and proapoptotic protein levels (Bax, cytochrome C) were altered.
• Increased generation of reactive oxygen species (ROS) was observed.

Conclusions:

• The novel 4-thiazolidinone derivatives demonstrate promising anticancer activity against breast cancer cell lines.
• The compounds effectively activate the intrinsic apoptotic pathway, leading to cancer cell death.
• These findings support the further development of 4-thiazolidinones as potential chemotherapeutic agents.
