NP1192
Based on 1 Customer Validation
NP1192 is a potent, selective PROTAC NAT10 degrader. NP1192 promotes NAT10 ubiquitination and degradation. NP1192 inhibits ac4C modification. NP1192 demonstrates dual inhibition of hypoxia-driven glycolysis and immunosuppression via NAT10/HIF-1α/PD-L1 axis disruption, achieving superior antitumor efficacy and synergizing with anti-PD-L1 both in vitro and in vivo. NP1192 can be used for ovarian, cervical, and glioblastoma cancer research.

NP1192 (0-20 μM, 24-48 h) induces NAT10 degradation in SiHa (human) and U14 (murine) CCa cell lines in a dose-and time-dependent manner, through the ubiquitin-proteasome system (UPS) rather than via lysosomal pathways[1].
NP1192 (36 h) inhibits cervical cancer (SiHa) cell growth with an IC50 of 7.814 μM (76.2 μM in resistant cells) and additionally shows dose-dependent efficacy in organoids, with IC50 values of 9.947, 3.048, and 13.76 μM for ovarian (OV), cervical (CESC), and glioblastoma (GBM) models, respectively[1].
NP1192 (20 μM, 0-72 h and 2 weeks) significantly reduces cell viability, induces cell cycle arrest, and suppresses invasion and clonogenic growth in CCa cells[1].
NP1192 (0.195-50 μM, 1-8 days) induces a pronounced reduction in organoid size and number across tumor models (ovarian, cervical, and glioblastoma), while the corresponding normal organoids remained unaltered, indicating minimal cytotoxicity to nonmalignant tissues[1].
NP1192 (20 μM, 36 h) reprograms the hypoxic tumor microenvironment (TME) and metabolism in CCa cells by degrading NAT10 and thereby impairing HIF-1α expression, which disrupts glycolysis as evidenced by reduced glucose uptake and lactate production alongside elevated ATP levels[1].

Cell Line:SiHa, U14, and HFF-1 cells
-
Concentration:0, 1.25, 2.5, 5, 10 and 20 μM
-
Incubation Time:24, 36 and 48 h
-
Result:Led to a substantial depletion of total NAT10 protein in SiHa (human) and U14 (murine) CCa cell lines in a a dose-and time-dependent manner.
Induced degradation rates of 28%, 32%, 40%, and 43% in SiHa cells at concentrations of 1.25, 2.5, 5, and 10 μM, respectively, with a maximum of 69% degradation at 20 μM after 36 h and only 20% degradation after 24 h.
Led to a nearly 70% reduction in the NAT10 protein content in murine U14 cervical cells after 36 h.
Did not exhibit the classical hook effect even at concentrations as high as 20 μM.
Failed to degrade NAT10 significantly when co-treated with MG132 (HY-13259), whereas Bafilomycin A1 (HY-100558) exerted no discernible effect on its degradation efficacy.
Substantially induced minimal cytotoxicity in nonmalignant HFF-1 cells with low NAT10 expression.
Decreased HIF-1α protein levels.
Reversed the induction of hypoxia-related genes under hypoxic conditions, such as HIF1A and PD-L1, at both mRNA and protein levels.

-
Result:Significantly reduced tumor volume and tumor burden compared to DMSO at 25 mg/kg.

Showed the most pronounced reduction (>80%) in tumor lactate levels when combined with anti-PD-L1 antibody (2.5 mg/kg).
¹⁸F-FDG PET–CT imaging revealed minimal metabolic uptake when combined with anti-PD-L1 antibody, suggesting effective suppresses tumor metabolic activity.
