Despite the considerable achievements of antibodies targeting PD-1/PD-L1 in cancer immunotherapy, limitations antitumor immune response and pharmacokinetics hinder their clinical adoption. Small molecules toward PD-L1 degradation signifies an innovative avenue to modulate axis. Herein, we unveil a comprehensive engineering involving development new degraders based on berberine (BBR) palmatine (PMT) bioactive frameworks explore translational potential for immunotherapy using peptide-drug conjugate strategy. Chemical modifications at O-9 position PMT dramatically enhance capacity. Further conjugation with anti-PD-L1 peptide featuring disulfide linkers enables efficient GSH-specific prodrug activation, yielding synergistic immunotherapeutic benefits through both external blockade internal mechanisms. This work elucidates compelling charm discovery application degraders, offering solutions challenges advancing widespread clinics.

Targeting programmed cell death protein-1 (PD-1)/programmed death-ligand 1 (PD-L1) pathway has been considered as one of the most promising strategies for tumor immunotherapy. However, single-target PD-1/PD-L1 inhibitors frequently exhibit limited efficacy, highlighting urgent need new therapies. Herein, a series dual PD-L1/HDAC3 were developed through pharmacophore fusion strategy first time. Among them, compound PH3 was identified inhibitor, with potent inhibitory activity (IC50 = 89.4 nM) and selective HDAC3 107 nM). Moreover, exhibited superior in vitro antitumor activities immune activation effects. Additionally, showed dose-dependent efficacy B16-F10 melanoma mouse model without obvious toxicity. Furthermore, increased infiltration CD3+CD8+ CD3+CD4+ cells microenvironment. Collectively, represented novel inhibitor deserving further investigation immunotherapy agent.

Abstract Programmed death‐ligand 1 (PD‐L1) is a critical immune checkpoint protein that facilitates tumor evasion. While antibody‐based PD‐1/PD‐L1 inhibitors have shown promise, their limitations necessitate the development of alternative therapeutic strategies. This work addresses these challenges by developing hexapeptide, KFM (Lys‐Phe‐Met‐Phe‐Met‐Lys), capable both directly downregulating PD‐L1 and self‐assembling into ROS‐responsive supramolecular hydrogel. dual functionality allows Gel to function as localized drug delivery system inhibitor. Loading hydrogel with mitoxantrone (MTX) metformin (MET) further enhances effect combining chemotherapy downregulation. In vitro in vivo studies demonstrate significant growth inhibition, increased CD8+ T cell infiltration, reduced intratumoral expression following peritumoral administration. Mechanistically, promotes degradation via ubiquitin‐dependent pathway. “carrier‐free” expands role hydrogels beyond passive carriers active immunotherapeutic agents, offering promising new strategy for cancer therapy.
