Lymphotoxin Beta binds to LTα to form membrane-anchored heterotrimers that activate canonical/noncanonical nuclear factor-κB (NF-κB) signaling thus inducing chemokine, cytokine or adhesion molecule expression, cell proliferation and cell survival. Lymphotoxin Beta also shows anti-inflammatory, anti-cancer activity. Lymphotoxin Beta regulates hepatic stellate cell function and wound healing in a murine model of chronic liver injury. TNFSF3/Lymphotoxin Beta Protein, Cynomolgus (sf9, His) is a recombinant protein with a N-Terminal His label, It consists of 197 amino acids (Q49-G244) and is produced in Sf9 insect cells.
Leukotriene B4-d4 is the deuterium labeled Leukotriene B4. Leukotriene B4 (LTB4) is known as one of the most potent chemoattractants and activators of leukocytes and is involved in inflammatory diseases. Leukotriene B4 is also an alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs[1][2][3].
Olsalazine-d3 is deuterated labeled Olsalazine (HY-B0174A). Olsalazine is a potent inhibitor of macrophages chemotaxis to LTB4 with an IC50 value of 0.39 mM, also reduces the synthesis of 5-hydroxyeicosatetraenoic acid (5-HETE), 11-HETE, 12-HETE, and 15-HETE in polymorphonuclear leukocyte (PMNL) and mononuclear cells (MNL). Olsalazine can be used for researching ulcerative colitis. Anti-inflammatory activity .
Olsalazine-d3, 15N is 15N and deuterated labeled Olsalazine (HY-B0174A). Olsalazine is a potent inhibitor of macrophages chemotaxis to LTB4 with an IC50 value of 0.39 mM, also reduces the synthesis of 5-hydroxyeicosatetraenoic acid (5-HETE), 11-HETE, 12-HETE, and 15-HETE in polymorphonuclear leukocyte (PMNL) and mononuclear cells (MNL). Olsalazine can be used for researching ulcerative colitis. Anti-inflammatory activity .
