Design, synthesis and pharmacological evaluation of β-carboline derivatives as potential antitumor agent via...

Area of Science:

• Medicinal Chemistry
• Pharmacology
• Oncology

Background:

• Anticancer drug development is crucial for managing cancer.
• Beta-carboline derivatives are a class of compounds with potential therapeutic applications.
• Novel derivatives need to be synthesized and evaluated for efficacy.

Purpose of the Study:

• To design and synthesize novel beta-carboline derivatives as potential anticancer agents.
• To evaluate the antiproliferative activity of these compounds against various cancer cell lines.
• To investigate the in vivo antitumor efficiency and mechanism of action of the most potent derivative.

Main Methods:

• Synthesis of novel beta-carboline derivatives.
• In vitro antiproliferative assays against 786-0, HT-29, and 22RV1 cell lines.
• In vivo antitumor evaluation in a mouse colorectal cancer homograft model.
• Investigation of the mechanism of action, including autophagy pathway analysis.

Main Results:

• Compound 6g exhibited potent antiproliferative activity with IC50 values in the low micromolar range against tested cell lines.
• Compound 6g significantly suppressed tumor growth and reduced tumor weight in a mouse model.
• Mechanism studies revealed that compound 6g inhibits cell growth by activating the ATG5/ATG7-dependent autophagic pathway.

Conclusions:

• Compound 6g is a promising anticancer agent with significant in vitro and in vivo activity.
• The observed anticancer effects are mediated through the induction of autophagy.
• These beta-carboline derivatives represent potential candidates for the development of novel colorectal cancer therapeutics.
