Abstract

A method for reducing macrophage migration inhibitory factor (MIF or MMIF) cytokine or its biological activity, including the step of administering an isothiocyanate functional surfactant to a patient having a disease or condition wherein MIF cytokine or its biological activity is implicated in the disease or condition. In one embodiment, the protonated form of the isothiocyanate functional surfactant is represented by the following chemical structure:
