STAT1 Activator

BCI-137 is a Argonaute 2 (AGO2) inhibitor. By inhibiting AGO2 function, reducing PTPN6/SHP-1 protein levels and enhancing STAT1 phosphorylation, BCI-137 restores the sensitivity of tumor cells to IFN-γ. BCI-137 effectively enhances the recruitment, activation and cytotoxicity of CD8⁺ T cells. BCI-137 exerts a synergistic effect with anti-PD-1 antibodies and significantly reduces tumor volume in preclinical mouse models. BCI-137 exhibits favorable safety profiles and does not cause significant weight loss or death in mice. BCI-137 can be used in research related to bladder cancer, colorectal cancer, melanoma and other related fields.

SB02024 is a potent and orally active VPS34 inhibitor. SB02024 inhibits Vps34 kinase activity. SB02024 induces CCL5 and CXCL10 via STAT1/IRF7. SB02024 shows anticancer activity.

KMR-206 is a PARP7 inhibitor with an IC₅₀ of 13.7 nM. KMR-206 relieves AHR-mediated transcriptional repression and enhances CYP1A1 expression in the presence of TCDD. KMR-206 induces the STING-dependent IFN-β signaling pathway and increases the levels of STAT1, pSTAT1 and nuclear PARP7 in cancer cells. KMR-206 reduces the viability of lung adenocarcinoma cells, enhances radiation-induced immunogenic signals, and induces the production of immunogenic signals in glioblastoma cancer stem cells. KMR-206 destabilizes FRA1 to increase IRF1 levels and promotes the IRF3-CBP/p300 interaction. KMR-206 can be used in studies related to lung adenocarcinoma and glioblastoma.

RBN012811 is a highly selective PROTAC-based PARP14 degrader. RBN012811 forms a ternary complex with cereblon by binding to the NAD⁺ site of PARP14, and mediates the specific degradation of PARP14 via the ubiquitin-proteasome pathway (IC₅₀=10 nM). RBN012811 effectively depletes endogenous PARP14 in various cell lines and primary human macrophages, thereby downregulating IL-10 production and IFN-β mRNA levels, increasing phosphorylated STAT1 levels to enhance inflammatory signaling, and inhibiting interferon-induced ADPr condensate formation. RBN012811 also modulates viral replication, exhibiting increased HSV1 replication while reducing VSV replication. RBN012811 has important application value in research related to cancer and viral infections.

Fa-Au is a TrxR inhibitor. Fa-Au downregulates GPX4, induces oxidative stress, mitochondria-associated ferroptosis (ferroptosis) and immunogenic cell death. Fa-Au induces ROS production in hepatoma cells. Fa-Au remodels the tumor immune microenvironment via M1 macrophage polarization, dendritic cell maturation, CD8+ T cell activation and reduction of regulatory T cells. Fa-Au induces an anti-tumor immune feedback loop through the IFNγ/STAT1/SLC7A11 axis. Fa-Au inhibits tumor growth. Fa-Au is applicable to hepatocellular carcinoma-related research.

BAY-356, a potent TWEAK receptor agonist, is an aglycosylated anti-TWEAK receptor antibody. BAY-356 triggers TWEAKR hyperactivation, activates NFκB and STAT1 pathways, and undergoes TWEAKR-dependent internalization. BAY-356 can be used for the research of colorectal cancer, bladder cancer, non-small cell lung cancer and pancreatic cancer^[1][2].

PD-305 is a selective PTPN2 PROTAC degrader, with DC₅₀ values of 0.25 nM and 5.11 nM against PTPN2 and PTPN1, respectively. PD-305 enhances IFN-γ-induced STAT1 phosphorylation, inhibits the proliferation of IFN-γ-stimulated colorectal cancer cells, promotes CD8⁺ T cell activation, enhances the tumor-killing activity of T cells, and suppresses tumor growth in mouse models. PD-305 can be used for the research of colorectal cancer.

ADGRL1-IN-1 is a ADGRL1 inhibitor. ADGRL1-IN-1 activates the GSK3β-STAT1 signaling axis. ADGRL1-IN-1 induces anti-tumor immunity in a CT26 colorectal cancer mouse model. ADGRL1-IN-1 can be used in studies related to colorectal cancer.

Polθ-IN-11 is an orally active DNA polymerase θ (Polθ) ATPase inhibitor with an IC₅₀ of 4.3 nM against human targets. Polθ-IN-11 activates the cGAS-STING pathway. Polθ-IN-11 upregulates the expression of PD-L1 in HR-deficient cancer cells. Polθ-IN-11 acts synergistically with PARP inhibition in HR-deficient cancer cells and in vivo xenograft models. Polθ-IN-11 can be used in studies related to HR-deficient cancers.
