DC49130	PD-1/PD-L1-IN-23	PD-1/PD-L1-IN-23 is a potent and orally active inhibitor of PD-1/PD-L1. PD-1/PD-L1-IN-23 is an ester prodrug of L7. L7 is a benzo[c][1,2,5]oxadiazole derivative and biologically evaluated as inhibitors of PD-L1. PD-1/PD-L1-IN-23 displays significant antitumor effects in tumor models of syngeneic and PD-L1 humanized mice.
DC44157	PD-1/PD-L1-IN-NP19	PD-1/PD-L1-IN-NP19 is a PD-1/PD-L1 inhibitor, with an IC50 of 12.5 nM for human PD-1/PD-L1 interaction. PD-1/PD-L1-IN-NP19 could activate the immune microenvironment in tumor, which may contribute to its antitumor effects.
DC44154	PD-1/PD-L1-IN 3	PD-1/PD-L1-IN 3, a macrocyclic peptide, is a potent and selective inhibitor of the PD-1/PD-L1 and CD80/PD-L1 interactions extracted from patent WO2014151634A1, compound No.1. PD-1/PD-L1-IN 3 interferes with PD-L1 binding to PD-1 and CD80 by binding to PD-L1, with IC50s of 5.60 nM and 7.04 nM, respectively. PD-1/PD-L1-IN 3 can be used for the research of various diseases, including cancer and infectious diseases.
DC42714	BMS-8	BMS-8 inhibits the PD-1/PD-L1 interaction with IC50 of 7.2 μM. BMS-8, binds directly to PD-L1 and induces formation of PD-L1 homodimers, which in turn prevents the interaction with PD-1[1].
DC12058	BMS-1166 (PD-1/PD-L1-IN1)	BMS-1166 is a potent PD-1/PD-L1 interaction inhibitor with an IC50 of 1.4 nM.
DC76689	LTB	LTB is a prodrug formed by coupling glycolysis inhibitor (Lonidamine) with PD1/PDL1 blocker (BMS-1) by thioketal linkage. LTB can further encapsulate photosensitizer chlorine e6 (Ce6)) to construct a co-delivery photodynamic nanoplatform (LTB-6 NPs) by self-assembly.
DC76688	Lon-TK	Lon-TK is a glycolysis inhibitor + linker conjugate of LTB. LTB is an intelligent responsive prodrug that connects Lonidamine (Lon) and a PD-L1 inhibitor (BMS-1) through a thioketal linker. It significantly inhibits the glycolytic metabolism of tumor cells and blocks the PD-1/PD-L1 immune escape pathway. Lon-TK shows potential for application in photodynamic-enhanced immunotherapy research.
DC76687	D5B	D5B is a potent and selective PD-L1 inhibitor. D5B has been modified by DBCO. The EC50 of D5B degrading PD-L1 in 4T1 and B16-F10 tumor cells are 5.4 μM and 6.2 μM, respectively. D5B can block PD-L1/PD-1 interaction and has anti-tumor activity.
DC76686	AB-3PRGD2	AB-3PRGD2 is a radiotherapeutic agent targeting integrin αvβ3. AB-3PRGD2 shows improved tumor uptake and prolonged tumor retention, leading to significantly enhanced tumor growth suppression. AB-3PRGD2 can remodel the tumor immune microenvironment by upregulating PD-L1 expression and increasing tumor-infiltrating CD8+ T cells.
DC73542	YPD-29B	YPD-29B is a potent, specific programmed cell death ligand 1 (PD-L1) inhibitor, effectively blocks the binding of PD-1 and PD-L1 with IC50 of 0.08 pM in HTRF protein-protein interaction assays.
