Dipyrithione

Dipyrithione (CAS No.: 3696-28-4) is a pyrithione-derived small molecule widely studied in biomedical research as a potent antimicrobial and antiproliferative agent with broad-spectrum biological activity. It exhibits pronounced antifungal effects and inhibits cellular proliferation in diverse experimental systems, with activity generally observed in the nanomolar to low micromolar range depending on cell type and assay conditions. Mechanistically, Dipyrithione has been shown to induce apoptosis and enforce cell cycle arrest at the G1 phase, suggesting modulation of key regulatory pathways governing cell survival and proliferation, while its reported cytotoxicity and broad-spectrum antitumor properties indicate interference with essential intracellular processes such as redox homeostasis and metal ion balance. In addition, in vivo studies demonstrate anti-inflammatory activity, supporting its utility in investigating inflammation-associated signaling pathways. Owing to these combined properties, Dipyrithione is frequently employed in studies of fungal biology, dermatophyte-related disease models, and cancer cell biology, as well as in compound screening workflows aimed at identifying modulators of cell growth and survival. Experimental concentrations or dosing regimens vary according to specific model systems and research objectives.
