Design, synthesis and preliminary bioactivity studies of indomethacin derivatives as Bcl-2/Mcl-1 dual inhibitors

Area of Science:

• Biochemistry
• Molecular Biology
• Medicinal Chemistry

Background:

• Bcl-2 family proteins regulate apoptosis and are key targets in cancer treatment.
• Developing effective inhibitors for Bcl-2 family proteins is a significant therapeutic goal.

Purpose of the Study:

• To design and synthesize novel indomethacin derivatives as potential inhibitors of Bcl-2 family proteins.
• To evaluate the binding affinity and anti-proliferative effects of these derivatives against cancer cells.

Main Methods:

• Synthesis of indomethacin derivatives.
• Binding assays to assess affinity for Bcl-2, Mcl-1, and Bcl-X_L proteins.
• MTT assays and apoptotic assays to determine anti-proliferative activity.

Main Results:

• Several synthesized compounds exhibited potent binding affinity to Bcl-2 and Mcl-1, but not Bcl-X_L.
• Compound 8j displayed superior anti-proliferative activity compared to the known Bcl-2 inhibitor WL-276.
• The study identified specific indomethacin derivatives with promising Bcl-2/Mcl-1 inhibitory potential.

Conclusions:

• Indomethacin derivatives represent a promising class of compounds for targeting Bcl-2 family proteins in cancer therapy.
• Compound 8j is a potent inhibitor with potential for further development as an anti-cancer agent.
• Selective inhibition of Bcl-2/Mcl-1 over Bcl-X_L may offer therapeutic advantages.
