Reinvestigating Pyrrol-2-One-Based Compounds: From Antimicrobial Agents to Promising Antitumor Candidates

Abstract: Background: Heteroaromatic iodine-containing compounds have been previously recognized for their broad-spectrum antimicrobial activity. This study aims to systematically investigate their potential repurposing as anticancer agents, with a particular focus on understanding the structural determinants that influence their cytotoxicity and selectivity toward malignant cells. Methods: A series of heteroaromatic iodine-containing derivatives were synthesized and evaluated for anticancer activity. Their cytotoxic effects were measured and compared between cancerous and normal cell lines to determine selectivity. Structural features, including heteroaromatic moieties and substituents, were analyzed to identify correlations with biological activity. Results: Among the tested compounds, derivatives 3e, 3g, and 3l demonstrated significant cytotoxic effects while exhibiting favorable selectivity indices. These findings indicate that these compounds preferentially target malignant cells over normal cells, thereby mitigating the issue of systemic toxicity often associated with traditional chemotherapeutics. The enhanced anticancer activity appears to be influenced by specific structural elements within the heteroaromatic framework. Conclusions: The study highlights the potential of heteroaromatic iodine-containing compounds as promising anticancer candidates. Rational structural modifications within these heterocyclic systems can effectively modulate bioactivity and improve therapeutic selectivity. These results support further development of this compound class for anticancer applications.
