Pactimibe is a ACAT inhibitor. It has anti-atherosclerotic activity.

TMI-1 (WAY-171318), a novel orally active inhibitor of ADAM17 (TACE) and MMP, induces tumor apoptosis in a breast cancer.

VAS 3947 is a specific inhibitor of NADPH oxidase (NOX).VAS 3947 has a potent anti-platelet effect, inducing apoptosis through UPR activation, mainly due to protein aggregation and misfolding, independent of anti-NOX activity.

DY-46-2 is a selective non-nucleoside DNA methyltransferase 3A (DNMT3A) inhibitor (IC50: 0.39 ± 0.23 μM) with anticancer activity for the study of cancer and tumors.

Pactimibe sulfate (CS-505) is a dual ACAT1/2 inhibitor, acting on ACAT1 (IC50: 4.9 μM) and ACAT2 (IC50: 3.0 μM). It inhibits oleoyl-CoA non-competitively (Ki: 5.6 μM) and significantly inhibits cholesterol ester formation (IC50: 6.7 μM). Pactimibe sulfate reduces plasma cholesterol activity and has anti-atherogenic potential.

Emricasan (IDN-6556) is a pan-caspase inhibitor with irreversible properties. Emricasan has anti-inflammatory and anti-apoptotic activity and can be used in the treatment of infections and liver failure, etc. Emricasan also inhibits Zika virus infections.

Phorbol 12-myristate 13-acetate (PMA) is a natural phorbol ester that acts as an activator of PKC, SphK, and NF-κB, and is commonly used to induce differentiation of THP-1 cells and establish dermatitis models.

Lsd1-in-20 is a potent dual inhibitor of LSD1/G9a with Ki values of 0.44 and 0.68 μM, respectively. LSD1-IN-20 showed antiproliferative activity against THP-1 leukemia cells and MDA-MB-231 breast cancer cells in vitro, with IC50 of 0.51 and 1.60 μM, respectively, at 72 h.

CU-115 is a selective and potent TLR8 antagonist with IC50 of 1.04 µM and =>50 µM for TLR8 and TLR7, respectively. CU-115 decreases production of TNF-α and IL-1β activated by R-848 in THP-1 cells.

NLRP3-IN-NBC6 is a potent, selective NLRP3 inflammasome inhibitor with an IC50 of 574 nM. It acts independently of Ca 2+ and inhibits Nigericin-induced inflammasome activation in THP-1 cells, as well as Imiquimod-induced IL-1β release from LPS-primed bone marrow-derived macrophages (BMDMs) [1].

Manumycin A is an antibiotic with anticancer activity and is a mammalian thioredoxin reductase-1 (TrxR-1) inhibitor.Manumycin A inhibits the production of IL-1β, IL-6, and IL-8 in TNF alpha-stimulated THP-1 cells and peripheral blood mononuclear cells in a dose-dependent manner, inducing apoptosis.

Propargyl-PEG4-acid is a PEG-based PROTAC linker used in the synthesis of BTK-IAP PROTACs, including Ibrutinib-based PROTAC 2 and its analogue PROTAC 3. PROTAC 3 induces BTK degradation with a DC50 of 200 nM in THP-1 cells[1].

NLRP3-IN-49 (compound Z48) is a potent and specific inhibitor of NLRP3, displaying IC50 values of 0.26 μM in THP-1 cells and 0.21 μM in mouse bone marrow-derived macrophages. It directly binds to the NLRP3 protein with a dissociation constant (Kd) of 1.05 μM, effectively preventing the assembly and activation of the NLRP3 inflammasome, thereby exhibiting anti-inflammatory properties. NLRP3-IN-49 is utilized in the research of inflammatory bowel disease.

NLRP3-IN-46 (Compound 3k) activates the cholinergic anti-inflammatory pathway involved in neuro-immune modulation, thereby inhibiting the activation of the NLRP3 inflammasome. Furthermore, NLRP3-IN-46 suppresses the production of IL-1β in THP-1 cells induced by Uric acid sodium, making it relevant for research in gouty arthritis.
