LD4172	PROTACs RIP kinase Apoptosis	Inflammation/Immunology Cancer
LD4172 is a selective RIPK1 PROTAC degrader with a K_i of 4.8 nM. LD4172 induces RIPK1 protein degradation via ternary complex formation with RIPK1 and VHL E3 ligase, driving ubiquitination and proteasomal breakdown. LD4172 abrogates TNF-induced classical NF-κB signaling in TRAF2-deficient cells, impairing IκBα phosphorylation and degradation, and reducing IL-8 production. LD4172 induces apoptosis and immunogenic cell death in tumor cells, enhances tumor-infiltrating lymphocyte responses, and sensitizes tumors to anti-PD1 therapy. LD4172 acts as a chemical probe for investigating RIPK1 scaffolding functions. LD4172 can be used for the research of melanoma, colon cancer .

Sabestomig AZD7789	PD-1/PD-L1 Tim3	Inflammation/Immunology
Sabestomig (AZD7789) is a monovalent bispecific antibody targeting PD-1 and TIM-3. Sabestomig binds to PD-1 and an epitope in the TIM-3 IgV domain outside the phosphatidylserine-binding cleft, thereby precisely regulating immune responses. Sabestomig promotes IL-2 production, efferocytosis and cross-presentation of tumor antigens, and enhances the release of anti-tumor T cell cytokines, cytotoxicity, and secretion of IFN-γ. Sabestomig inhibits the growth of solid tumors, prolongs the duration of tumor suppression, and significantly enhances anti-tumor responses following anti-PD-1 therapy. Sabestomig has been used in studies related to non-small cell lung cancer and classical Hodgkin lymphoma .

HY-P992353

ES009	LILRB	Cancer
ES009 is a high-affinity LILRB2 antagonist, with IC₅₀ values of 14.07 nM and 18.61 nM for inhibiting hLILRB2-huANGPTL3 and hLILRB2-huANGPTL4, respectively. ES009 specifically blocks the interactions between LILRB2 and MHC class I as well as non-MHC ligands, thereby effectively inhibiting receptor activation. ES009 can reprogram anti-inflammatory myeloid cells and induce their conversion to a pro-inflammatory phenotype, and also reverse the T cell suppression mediated by macrophages. When combined with anti-PD-1 blockade therapy, ES009 synergistically enhances T cell activation. ES009 can be used in research related to advanced solid tumors and ovarian cancer .

3-Oxochol-5-en-24-oic acid	Androgen Receptor Endogenous Metabolite	Inflammation/Immunology Cancer
3-Oxochol-5-en-24-oic acid is a rare bile acid produced by the intestinal microbiota. 3-Oxochol-5-en-24-oic acid is a potent antagonist of the human androgen receptor (hAR), with an IC₅₀ of 119.4 nM. 3-Oxochol-5-en-24-oic acid has no significant agonistic or antagonistic effects on estrogen receptors (ER) or glucocorticoid receptors (GR). 3-Oxochol-5-en-24-oic acid effectively inhibits the growth of prostate cancer cells. In animal models, it enhances the efficacy of anti-PD-1 therapy by regulating the differentiation of CD8 ⁺ T cells. 3-Oxochol-5-en-24-oic acid can be used for research on regulating host immunity and anti-tumor studies .

HY-181718

Necroptosis inducer 1	Necroptosis TrxR Reactive Oxygen Species (ROS)	Cancer
Necroptosis inducer 1 is a necroptosis inducer. Necroptosis inducer 1 inhibits the activity of thioredoxin reductase (TrxR), elevates intracellular ROS levels, triggers ROS-mediated necroptosis, and induces necroptosis-dependent immunogenic cell death. Necroptosis inducer 1 inhibits tumor growth, remodels the tumor immune microenvironment, and exerts a synergistic effect with anti-PD-1 in animal models. Necroptosis inducer 1 is applicable to the research of colon cancer .
