NDI-101150
NDI-101150 is an orally active, potent and selective hematopoietic progenitor cell kinase 1 (HPK1) inhibitor with an IC50 of 0.7 nM. NDI-101150 blocks HPK1-mediated negative regulation of immune receptor signaling, inhibits immunosuppression of T cell activation, enhances antigen-specific antibody production and augments B-cell activation. NDI-101150 inhibits tumor growth in syngeneic tumor models, establishes durable antitumor immune memory, and synergizes with anti-PD1 to enhance exhausted T cell activity and drive tumor regressions. NDI-101150 can be used for the research of cancer, such as breast cancer and colon cancer.

NDI-101150 potently and selectively inhibits HPK1 in a cell-free biochemical assay with an IC50 of 0.7 nM, and exhibits high fold-selectivity over closely related MAP4K family kinases and immune cell signaling kinases[1].
NDI-101150 potently inhibits HPK1 in a cell-based assay with an IC50 of 41 nM[1].
NDI-101150 (1-10000 nM) reverses TGF-β-, PGE2, TREG, Adenosine (HY-B0228)-induced immunosuppression of human T cells, restoring IFN-γ, IL-2 production to naive T cell levels[1].
NDI-101150 (0.003-1.0 μM) induces dose-dependent increases in IFN-γ, TNF-α, and GM-CSF production in human mixed lymphocyte reactions, with responses surpassing naive T cell levels[1].
NDI-101150 reinvigorates exhausted human T cells, restoring IL-2 secretion after a 10-day stimulation/rest exhaustion protocol[1].
NDI-101150 is a highly potent and selective cell-free inhibitor of HPK1 kinase activity, with an IC50 of 0.7 nM, and exhibits exceptional selectivity over other MAP4K family members and critical immune cell kinases[2].
NDI-101150 dose-dependently inhibits SLP-76 phosphorylation in anti-CD3-stimulated human Jurkat T cells, with an IC50 of 41 nM[2].
NDI-101150 dose-dependently inhibits SLP-76 phosphorylation in anti-CD3-stimulated human CD4+ and CD8+ T cells (IC50 = 21 nM and 20 nM, respectively) without reducing cell viability[2].
NDI-101150 dose-dependently inhibits BLNK phosphorylation in anti-IgM-stimulated human B cells, with an IC50 of 48 nM[2].
NDI-101150 (0.001-1.0 μM; 72-96 h) dose-dependently enhances anti-CD3/CD28-induced cytokine secretion and proliferation in human primary CD4+ and CD8+ T cells, with EC50 values ranging from 11-17 nM for cytokines, and does not reduce cell viability[2].
NDI-101150 (0.0015-3.3 μM) dose-dependently enhances IFN-γ production in human mixed lymphocyte reactions[2].
NDI-101150 (0.03-3.0 μM) dose-dependently enhances anti-IgM-induced CD19+ B-cell activation, IgG secretion, and proliferation[2].
NDI-101150 (1-10000 nM; 24-48 h) dose-dependently restores and enhances T-cell activation in human primary T cells suppressed by TGF-β, PGE2, or Adenosine, with cytokine secretion exceeding naïve T-cell levels at higher concentrations[2].
NDI-101150 (0.003-1.0 μM) dose-dependently reactivates exhausted human T cells in MLRs, inducing proliferation and cytokine secretion, and shows synergistic effects when combined with anti-PD-1[2].
