ES009
ES009 is a high-affinity LILRB2 antagonist, with IC50 values of 14.07 nM and 18.61 nM for inhibiting hLILRB2-huANGPTL3 and hLILRB2-huANGPTL4, respectively. ES009 specifically blocks the interactions between LILRB2 and MHC class I as well as non-MHC ligands, thereby effectively inhibiting receptor activation. ES009 can reprogram anti-inflammatory myeloid cells and induce their conversion to a pro-inflammatory phenotype, and also reverse the T cell suppression mediated by macrophages. When combined with anti-PD-1 blockade therapy, ES009 synergistically enhances T cell activation. ES009 can be used in research related to advanced solid tumors and ovarian cancer.

ES009 binds to human LILRB2 overexpressed on EL4-huLILRB2 cells, with an EC50 of 0.49 nM[1].
ES009 potently blocks the interactions between human LILRB2 and the MHC class I ligands HLA-G and HLA-A2 on EL4-huLILRB2 cells, with IC50 values of 0.16 nM and 0.24 nM, respectively[1].
ES009 induces a proinflammatory phenotype in human monocyte-derived dendritic cells by blocking LILRB2[3].
