SAR405 R enantiomer is primarily utilized in research settings, particularly in the study of autophagy and cancer biology. It functions as a potent and selective inhibitor of VPS34, a key enzyme involved in the regulation of autophagy. By inhibiting VPS34, SAR405 R enantiomer helps researchers understand the role of autophagy in cellular processes and its implications in diseases such as cancer. This compound is valuable in preclinical studies to explore potential therapeutic strategies targeting autophagy pathways, offering insights into drug development for cancer treatment and other autophagy-related disorders. Its specificity and efficacy make it a critical tool in advancing biomedical research.
