Lipopolysaccharides, from E. coli O55:B5

646 Publications Verification

Cat. No.: HY-D1056

Synonyms: LPS, from Escherichia coli (O55:B5)

Category:

Natural Products Microorganisms Disease Research Fields Inflammation/Immunology

Target:

Toll-like Receptor (TLR)

Lipopolysaccharides, from E. coli O55:B5 (LPS, from Escherichia coli (O55:B5)) are endotoxins and TLR4 activators extracted from Escherichia coli (E. coli O55:B5) and are classified as S (smooth) type LPS. Lipopolysaccharides, from E. coli O55:B5 possess the typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from E. coli O55:B5 activate TLR-4 in immune cells, exhibit high pyrogenicity, and demonstrate dose and serotype specificity. Lipopolysaccharides, from E. coli O55:B5 can be widely used to induce cellular inflammation and establish animal models related to inflammation .
It is recommended to prepare a solution with concentration ≥2 mg/mL. Vortex thoroughly for more than 10 minutes. Due to the adsorption characteristics of LPS, silanized container or low adsorption centrifuge tubes should be used for aliquoting and storage, and mix thoroughly before use.

Cyclosporin A

223 Cited Publications

Cat. No.: HY-B0579

CAS No.: 59865-13-3

Synonyms: Cyclosporine A; Ciclosporin A; CsA

Category:

Natural Products Microorganisms Anti-aging Disease Research Fields Inflammation/Immunology Cancer

Target:

Molecular Glues Complement System Antibiotic Cyclophilin

Cyclosporin A (Cyclosporine A) is an immunosuppressant which binds to the cyclophilin and inhibits phosphatase activity of protein phosphatase 2B (PP2B/calcineurin) with an IC₅₀ of 5 nM . Cyclosporin A is a molecular glue, binds to cyclophilin and calcineurin, leading to inactivation of nuclear Factor of activated T Cells (NFAT) and a subsequent decrease in the immune response. Cyclosporin A also inhibits CD11a/CD18 adhesion .

Fatostatin

60 Cited Publications

Cat. No.: HY-14452

CAS No.: 125256-00-0

Purity: 99.85%

Synonyms: 125B11

Target:

Fatty Acid Synthase (FASN)

Research Areas:

Cancer

Fatostatin (125B11), a specific inhibitor of SREBP activation, impairs the activation of SREBP-1 and SREBP-2. Fatostatin binds to SCAP (SREBP cleavage-activating protein), and inhibits the ER-Golgi translocation of SREBPs. Fatostatin decreases the transcription of lipogenic genes in cells. Fatostatin possesses antitumor properties, and lowers hyperglycemia in ob/ob mice .

Idasanutlin

52 Cited Publications

Cat. No.: HY-15676

CAS No.: 1229705-06-9

Purity: 99.93%

Synonyms: RG7388

Target:

MDM-2/p53 E1/E2/E3 Enzyme Apoptosis Pyroptosis Reactive Oxygen Species (ROS) Caspase

Research Areas:

Neurological Disease Cancer

Idasanutlin (RG7388) is an orally bioavailable MDM2 inhibitor with an IC₅₀ of 6 nM. Idasanutlin disrupts MDM2-p53 binding, stabilizes and activates p53, triggering cell cycle arrest, apoptosis, and reduced cancer cell viability. Idasanutlin reduces EGFR protein expression and phosphorylation, suppresses downstream SHP2, MEK1/2, ERK1/2, AKT, mTOR, p70(S6K1), and S6 signaling. Idasanutlin induces mitochondrial ROS production, drives p38 MAPK phosphorylation, upregulates NOXA, and mediates caspase-3-dependent apoptosis and gasdermin E-mediated pyroptosis. Idasanutlin can be used for the research of TP53-mutant non-small cell lung cancer, T-cell acute lymphoblastic leukemia, colorectal carcinoma, melanoma, diffuse large B-cell lymphoma, mantle cell lymphoma, non-Hodgkin lymphoma, severe fever with thrombocytopenia syndrome, neuroblastoma, acute lymphoblastic leukemia, relapsed or refractory acute myeloid leukemia, osteosarcoma, solid tumors, and hematological tumors .
