question: What is the role of 3,4-diaminobenzoic acid derivatives in the immune system?
answer: 3,4-diaminobenzoic acid derivatives are inhibitors of the oxytocinase subfamily of M1 aminopeptidases with immune-regulating properties. Cell-based analysis indicated that the lead compounds can be effective in downregulating macrophage activation induced by lipopolysaccharide and interferon-γ as well as cross-presentation by bone marrow-derived dendritic cells.
