Biological Activity

[Description]:

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].

[In Vitro]

L-Leucyl-L-Leucine methyl ester (1 mM; 0.5-2 h) enhances LRRK2-mediated Rab10 and Rab12 phosphorylation in MEFs and A549 cells[3]. L-Leucyl-L-Leucine methyl ester (10-250 μM; 15 min) is converted to a CCI3COOH-insoluble product by CD4- lymphocytes[2].
