KCL-HO-1i
KCL-HO-1i is an orally active heme oxygenase-1 (HO-1) inhibitor (rat HO-1: IC50 = 123 nM) and human HO-1: IC50 = 128 nM). KCL-HO-1i targets immunosuppressive LYVE-1+ perivascular tumor-associated macrophages (PvTAMs) in the tumor microenvironment (TME), reduces PvTAM-mediated immune exclusion. KCL-HO-1i demonstrates synergistic anti-tumor efficacy with chemotherapy in MMTV-PyMT spontaneous breast cancer mice or C57Bl/6 mice bearing subcutaneous MN-MCA1 sarcomas. KCL-HO-1i can be used for the study of cancer.

Biological Activity
|
HO-1 123 nM (IC50, rat splenic microsomes ) |
HO-1 128 nM (IC50, HEK293T cells ) |
KCL-HO-1i exhibits inhibitory activity against rat heme oxygenase-1 (HO-1) in rat splenic microsomes (IC50 = 123 nM) and HEK293T cells (IC50 = 128 nM)[1].
KCL-HO-1i (25 μM, 16 h) improves transendothelial migration of CD8+ T-cells, reversing the migration restriction caused by IL-6-polarized bone marrow-derived macrophages in a transwell assay[1].
