NP1192 is a potent, selective PROTAC NAT10 degrader that depletes NAT10 protein and inhibits ac4C modification in cancer cells. NP1192 demonstrates dual inhibition of hypoxia-driven glycolysis and immunosuppression via NAT10/HIF-1alpha/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. (Blue: CRBN ligand (HY-148834), Black: linker, Pink: NAT10 ligand (HY-16706))[1].
