Ferrichrome (iron-free) is an iron carrier derived from isoxazolates produced by various fungi, including U. sphaerogena, which enhances iron chelation and absorption in these organisms. In bacteria, Ferrichrome (iron-free) can be utilized as an exogenous iron carrier, such as in Pseudomonas aeruginosa and Vibrio parahaemolyticus. Ferrichrome (iron-free) (0.8 μM) inhibits the proliferation of mouse splenic monocytes induced by concanavalin A and reduces the expression of the IL-2 receptor on CD4+ T cells. Furthermore, Ferrichrome (iron-free) inhibits the heme-catalyzed oxidation of LDL by hydrogen peroxide in a concentration-dependent manner.

DMA4-H228 is an ionizable cationic lipidoid employed in creating lipid nanoparticles (LNPs) for mRNA delivery in vivo. These LNPs, enriched with DMA4-H228, specifically accumulate in antigen-presenting cells within the mouse spleen. When encapsulating mRNA for ovalbumin, these LNPs activate splenic antigen-presenting cells and elevate serum IFN-α levels in mice. Additionally, in a B16/F10-OVA murine melanoma model, such LNPs reduce tumor volume, increase intratumoral CD8+ T cells, and elevate serum anti-ovalbumin IgG titers.
