Oxadiazole-Functionalized Glycerol Ether Lipids: Synthesis, Biological Evaluation, and In Silico Studies

Area of Science:

• Medicinal Chemistry
• Organic Synthesis
• Biochemistry

Background:

• Ether lipids are important biomolecules with diverse physiological roles.
• Developing novel analogs can lead to new therapeutic agents.
• Nature-derived scaffolds offer unique structural features for drug design.

Purpose of the Study:

• To synthesize and characterize novel 1-O-alkyl-sn-glycerol (1-O-AKG) derivatives.
• To evaluate the antioxidant and antiproliferative activities of these new compounds.
• To explore potential mechanisms of action, including Wnt signaling pathway interactions.

Main Methods:

• Synthesis of 13 novel 1-O-AKG derivatives incorporating phenyl-oxadiazole and fatty acid fragments.
• Structural confirmation using NMR (¹H, ¹³C), FT-IR, and HRMS.
• Antioxidant assays (DPPH, ABTS, TBARS) and differential scanning calorimetry (DSC).
• In vitro antiproliferative assays against human cancer cell lines.
• Molecular docking studies against Wnt3 protein.

Main Results:

• Successful synthesis and structural elucidation of thirteen novel ether lipid analogs.
• Several derivatives exhibited significant free-radical scavenging activity, comparable to standard antioxidants.
• Compounds demonstrated moderate to good cytotoxic effects against tested cancer cell lines.
• Molecular docking revealed favorable binding interactions with Wnt3, suggesting potential Wnt pathway modulation.

Conclusions:

• The synthesized ether lipid analogs possess promising antioxidant and antiproliferative properties.
• These novel compounds may represent a new class of agents for cancer therapy.
• Further research into their mechanism of action and therapeutic potential is warranted.
