ISO-1(CAT: I003675) operates as an antagonist of macrophage migration inhibitory factor (MIF). This compound specifically targets MIF, an important regulatory protein. In vitro, studies demonstrate that ISO-1 hinders MIF tautomerase activity in a dose-dependent manner, with the hydroxylated phenyl analog being less potent. ISO-1’s potential mechanism includes the modulation of arachidonic acid release, while its application curtails cytokine activity and tumor necrosis factor release from macrophages. In vivo, ISO-1 administration showcases promising outcomes, leading to reduced implant size and vascularity, potentially influencing therapeutic strategies involving MIF-related processes and responses.
