Populene D analogues: design, concise synthesis and antiproliferative activity

Area of Science:

• Organic Chemistry
• Medicinal Chemistry
• Pharmacology

Background:

• Populene D analogues are compounds with potential therapeutic applications.
• Developing efficient synthetic routes for novel analogues is crucial for drug discovery.
• Understanding the antiproliferative activity of these compounds is essential for cancer research.

Purpose of the Study:

• To synthesize novel populene D analogues.
• To evaluate the antiproliferative activity of the synthesized compounds against various cancer cell lines.
• To identify compounds with selective toxicity towards specific cancer types.

Main Methods:

• An iodine-catalyzed Prins cyclization was employed for the efficient synthesis of nine populene D analogues.
• The synthesized pyran derivatives were tested for their antiproliferative effects.
• In vitro assays were conducted using multiple human cancer cell lines, including NCI-ADR/RES, OVCAR-3, and HT29.

Main Results:

• Nine populene D analogues were successfully synthesized.
• An isochromene derivative exhibited moderate antiproliferative activity (mean logGI(50) = 0.91).
• Several compounds demonstrated selectivity towards NCI-ADR/RES, OVCAR-3, and HT29 tumor cell lines.

Conclusions:

• The study established an efficient synthetic pathway to populene D analogues.
• The identified isochromene analogue shows potential as an anticancer agent.
• Selective compounds offer promise for targeted cancer therapy development.
