Use of L-Leucyl-L-Leucine methyl ester hydrobromide

L-Leucyl-L-Leucine methyl ester (LLOMe) hydrobromide, a dipeptide condensation product of L-leucine methyl ester generated by human monocytes or polymorphonuclear leukocytes, selectively eliminates lymphocytes with cytotoxic potential. L-Leucyl-L-Leucine methyl ester hydrobromide also can induce endolysosomal pathway stress[1][2][3].
