Description: Numidargistat, also known as INCB01158 and CB1158, is a potent and orally active arginase inhibitor with IC50=89 nM) . CB-1158 blocked myeloid cell-mediated suppression of T cell proliferation in vitro and reduced tumor growth in multiple mouse models of cancer, as a single agent and in combination with checkpoint blockade, adoptive T cell therapy, adoptive NK cell therapy, and the chemotherapy agent gemcitabine. CB-1158 increased tumor-infiltrating CD8+ T cells and NK cells, inflammatory cytokines, and expression of interferon-inducible genes. CB-1158 may be potentially useful in renal cell cancer, breast cancer, non-small cell lung cancer, acute myeloid leukemia, and other tumor types where arginase-secreting MDSCs are known to play an immunosuppressive role. (see ADDITIONAL INFORMATION in this web page for CB-1158 structure confusion).

More Info: Note: Currently there are two versions of CB-1158, which have different chemical structure and CAS#. 1. The first version is CAS#1345810-21-0 Smile code: ClC1=CC(Cl)=CC=C1CN2CCC(C(N)(CCCCB(O)O)C(O)=O)CC2 We listed this structure as CB1158. The structure can be found in below resources: (1). Current Opinion in Pharmaology 2017, 35. 30-39 (2). Pham et al . Drug Discov Today. 2018. Apr;23(4):871-878. (3). The CB1158 structure is further confirmed by Scifinder database, in which CB1158 has CAS#1345810-21-0 2. The second version is CAS#2095732-06-0 Smile code: O=C([C@]1(N)CN(C([C@H](C)N)=O)C[C@@H]1CCCB(O)O)O This structure can be found in below resource: https://chem.nlm.nih.gov/chemidplus/name/cb-1158 We keep post if we can confirm CB-1158 structure from authoritative resources.
