HBF-0259 is an inhibitors of hepatitis B virus surface antigen (HBsAg) secretion with an EC50 of 11.3 μM and a CC50 value of >50 μM in HepG2.2.15 cells. HBF-0259 had a EC50 of approximately 1.5 microM in a secondary, HBV-expressing cell line, with a concentration that exhibited 50% cytotoxicity of >50 microM. The equilibrium concentration of HBF-0259 in aqueous solution at physiological pH was 15 to 16 microM; the selective index was thus >9.

The nucleocapsid of the hepatitis B virus is covered by an envelope of HBV surface antigen (HBsAg), which has the common, group-specific determinant a. The four major subtypes of HBsAg, adw, adr, ayw and ayr, are generated, and they have been proposed to

MAGE-3 Antigen (167-176) (human) is an eight-amino-acid polypeptide epitope for HLA-B44 molecules, encoded by the melanoma antigen gene (MAGE) [1].

Blood group A antigen tetraose type 5 (A-Tetrasaccharide), a tetrasaccharide specific to blood group A, inhibits the binding of anti-A antibody to blood group A substance and can be isolated from polar bear milk samples [1] [2].

Anti-Mouse Pan-endothelial Cell Antigen/MECA-32 Antibody (MECA-32) is an IgG2a, κ antibody inhibitor derived from rats, targeting the mouse Pan-endothelial Cell Antigen/MECA-32.

Carcinoembryonic antigen peptide 1 (CEA peptide) is a Carcinoembryonic Antigen (CEA) derived peptide, of which sequen is YLSGANLNL. CEA is a broad-spectrum tumour marker, a glycoprotein produced by colorectal cancer tissues, which acts as an antigen to elicit an immune response.

SV40 large T antigen NLS, originating from Large T antigen residue 47 to 55, facilitates protein import into the cell nucleus. This peptide is specifically generated from Large T antigen residue 47 to 55.

SV40 large T antigen NLS acetate is from Large T antigen residue 47 to 55, enables protein import into cell nucleus.

Large T antigen - rhesus polyomavirus 560-568 has a peptide sequence of Ser-Glu-Phe-Leu-Leu-Glu-Lys-Arg-Ile. T antigen is required for viral DNA replication, transcription, and virion assembly.

MHC class II antigen (45-57) [Homo sapiens] is a peptide with the sequence H2N-Asp-Leu-Asp-Lys-Lys-Glu-Thr-Val-Trp-His-Leu-Glu- Glu-OH, MW= 1868.07. MHC (major histocompatibility complex) class II molecules are found only on antigen-presenting cells and l

MART-1 nonamer antigen (LAGIGILTV) is a melanoma antigen recognizable by T cells. It functions as a superagonist by enhancing the immunological response of specific T cells when induced ex vivo. Additionally, MART-1 nonamer antigen serves as a peptide model for designing antitumor vaccines.

Mage-1 Antigen (161-169), human is a polypeptide molecule with the sequence EADPTGHSY.

Prostate specific antigen protein (human) is a serine protease produced by the prostate epithelium. It is utilized in prostate cancer research.

SSA antigenic peptide represents the antigenic fragment associated with Sjögren's syndrome-related antigen A (SSA) [1].

Sorafenib (Bay 43-9006) is a multikinase inhibitor that targets Raf-1, B-Raf, VEGFR2, VEGFR3, VEGFR4, PDGFRβ, FLT3, c-Kit, and others (IC50=6/22/90/15/20/20/57/58 nM) with oral activity. It exhibits antitumor properties and can induce autophagy, apoptosis, and agonistic iron death.

Lipopolysaccharides (LPS), derived from Escherichia coli O55:B5, are essential components of the outer membrane of Gram-negative bacteria. Composed of lipid A, a core oligosaccharide, and an O-specific polysaccharide, LPS exhibits strong immunogenicity. It activates immune cells via the TLR4 receptor, induces chemotactic cell migration and cytokine secretion, and helps maintain the integrity of the bacterial outer membrane, protecting against bile salts and lipid-based antibiotics. LPS is commonly used to establish inflammatory models, including arthritis, chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), and gastrointestinal disease models.

Quizartinib (AC220) is an inhibitor of FLT3 (Kd: 1.6 nM) and demonstrates high selectivity for FLT3 when tested against a panel of 227 additional kinases.

Datopotamab deruxtecan (DS-1062) is a trophoblast cell surface antigen 2 (TROP2)-targeted antibody-drug conjugate (ADC) with antitumor activity. Datopotamab deruxtecan induces significant antibody-dependent cellular cytotoxicity in the presence of peripheral blood lymphocytes and inhibits tumor growth in xenograft models.

Gilteritinib (ASP2215) is a potent inhibitor of FMS-related tyrosine kinase 3 (FLT3) and AXL tyrosine kinase receptors (IC50 = 0.29 nM and <1 nM, respectively). In preclinical studies, gilteritinib demonstrated strong antileukemic and antitumor effects. Gilteritinib is currently in several Phase 3 clinical trials for acute myeloid leukemia.

Fostamatinib (R788)(IC50 of 41 nM), which is a prodrug of the active metabolite R406, is a Syk inhibitor. It does not work on Lyn.
