L-Leucyl-L-Leucine methyl ester hydrobromide

L-Leucyl-L-Leucine methyl ester hydrobromide (Leu-Leu-ome hydrobromide) is a dipeptide condensation product of L-leucine methyl ester generated by human monocytes or polymorphonuclear leukocytes, selectively eliminates cytotoxic lymphocytes, including natural killer (NK) cells, from mixed lymphocyte populations. It also induces stress in the endolysosomal pathway, highlighting its potential impact on immune cell regulation.
