LILRB Inhibitor

LILRB Inhibitors (8):

Cat. No. Product Name Effect Purity
  • HY-P990061
    Polzastobart
    		Inhibitor
    Polzastobart (JTX-8064) is a humanized IgG4 monoclonal antagonist antibody that selectively binds LILRB2 and prevents it from binding its ligands, classical and non-classical MHC I molecules. Polzastobart enhances pro-inflammatory cytokine production in macrophages by blocking the ability of LILRB2 to bind HLA-A/B and/or HLA-G, a marker of immunotolerance on cancer cells. Polzastobart is a macrophage immune checkpoint inhibitor.
  • HY-P990092
    Rolistobart
    		Inhibitor
    Rolistobart is a humanized immunoglobulin G4-kappa, anti-LILRB4/CD85k monoclonal antibody. Rolistobart is an immunostimulant and antineoplastic.
  • HY-P991727
    Zamristobart
    		Inhibitor
    Zamristobart is an anti-LILRB1 (leukocyte immunoglobulin-like receptor B1) IgG4κ type humanized antibody with immunostimulant and antineoplastic activities. The recommed isotype control is Human IgG4 (S228P) kappa, Isotype Control (HY-P99003).
  • HY-P992389
    IO-202
    		Inhibitor
    IO-202 is a high-affinity LILRB4/ILT3 binder and myeloid checkpoint inhibitor. IO-202 blocks APOE binding and LILRB4 activation to reverse T-cell suppression and enhance T-cell cytotoxicity, while eliminating LILRB4-high-expressing leukemic blasts via ADCC and ADCP mechanisms. IO-202 promotes dendritic cell maturation and antigen presentation, reshapes the phenotype of tumor-associated macrophages, and reduces myeloid-derived suppressor cells. IO-202 is widely applicable to research on relapsed/refractory acute myeloid leukemia (AML), chronic myelomonocytic leukemia (CMML), and solid tumors.
  • HY-P991308
    TRX385
    		Inhibitor
    TRX385 is a human monoclonal antibody (mAb) targeting LILRB4/ILT3/CD85k. TRX385 can be used in anticancer and antiviral research.
  • HY-P991307
    BND-35
    		Inhibitor
    BND-35 is a human monoclonal antibody (mAb) targeting LILRB4/ILT3/CD85k. BND-35 blocks the interaction of ILT3 with APOE and fibronectin, enhances the pro-inflammatory activity of various myeloid cells, and reverses ILT3-mediated immunosuppression of T cells by various suppressive myeloid cells. BND-35 has anti-tumor activity in the hILT3 transgenic mouse tumor model.
  • HY-P992388
    IO-108
    		Inhibitor
    IO-108 is a humanized IgG4 monoclonal antibody and a competitive inhibitor of LILRB2, with a KD value of 1.97 nM. IO-108 competitively blocks the binding of LILRB2 to its ligands including HLA-G, MHC-I, ANGPTL2 and SEMA4A, reprograms tumor-associated myeloid cells, drives the conversion of suppressive myeloid cells into a pro-inflammatory phenotype, and restores the cytotoxic activity of T cells and NK cells. IO-108 inhibits tumor growth in LILRB2 transgenic mouse models. IO-108 can be used for the research of solid tumors.
  • HY-P991306
    ATG-032
    		Inhibitor
    ATG-032 is a human monoclonal antibody (mAb) targeting LILRB2/ILT4. ATG-032 can be used in haematological malignancies research.
