Nucleoside Antimetabolite/Analog

RGB097 is a potent inhibitor of D-dopachrome tautomerase (D-DT), demonstrating an IC50 value of 0.5 µM. This compound exhibits significant biological activity and has potential applications in cancer research, particularly in elucidating the role of D-DT in oncogenesis and tumor progression.

MIF-IN-5 is a potent and reversible inhibitor of macrophage migration inhibitory factor (MIF), exhibiting a competitive mechanism of action. With an IC50 of 4.8 μM and a Ki value of 3.3 μM, it effectively disrupts MIF's biological activity. This compound is valuable for research applications involving inflammation, immune response modulation, and potential therapeutic strategies targeting various diseases associated with MIF dysregulation.

HTS05585 is a selective inhibitor of macrophage migration inhibitory factor (MIF), demonstrating a Kd value of 0.29 μM via microscale thermophoresis and 0.32±0.01 μM confirmed by isothermal titration calorimetry. This compound effectively inhibits the release of pro-inflammatory cytokines, including TNF-α, IL-6, and IL-1β, from LPS-stimulated macrophages. HTS05585 is a valuable tool for studying inflammation-related diseases, particularly in the context of sepsis research.

TE-11 is a potent MIF tautomerase inhibitor, exhibiting an IC50 value of 5.63 μM. This compound effectively ameliorates CD-like colitis and reduces migration of MIF-induced eosinophils and neutrophils. Additionally, TE-11 prevents M1 polarization and the associated metabolic reprogramming, making it a valuable tool for research in inflammatory and autoimmune disorders.
