    Resolvin D2 n-3 DPA
    T372892093111-29-4
    Resolvin D2 n-3 DPA (RvD2 n-3 DPA) is a specialized pro-resolving mediator (SPM).1It is formed from docosapentaenoic acid , an intermediate in the conversion of eicosapentaenoic acid to docosahexaenoic acid , in human leukocytes. RvD2 n-3 DPA (1 nM) reduces TNF-α-induced chemotaxis and adhesion of isolated human neutrophils.In vivo, RvD2 n-3 DPA (100 ng animal; i.v.) reduces peritoneal neutrophil infiltration and exudate levels of IL-6 and chemokine (C-C motif) ligand 2 (CCL2) in a mouse model of zymosan-induced inflammation. 1.Dalli, J., Colas, R.A., and Serhan, C.N.Novel n-3 immunoresolvents: Structures and actionsSci.

    Resolvin D4 (RvD4) is a specialized pro-resolving mediator derived from docosahexaenoic acid . [1] It has been detected in human milk, in the dorsal pouch of mice before and after infection with S. aureus, and in untreated tissues from humans, mice, and sardines.[2][3] RvD4, at 10 ng mouse, reduces neutrophil infiltration in zymosan A-induced peritonitis and, at 200 ng mouse, diminishes neutrophil infiltration in response to S. aureus infection. [3] With isolated cells, RvD4 promotes phagocytosis of bacteria, opsonized zymosan A, and apoptotic neutrophils by human macrophages.[3] It also promotes the clearance of apoptotic neutrophils by human fibroblasts.[3] Reference:[1].

  • Resolvin E4
    T380431781227-87-9
    Resolvin E4 (RvE4) is a member of the specialized pro-resolving mediator (SPM) family of bioactive lipids.1It is produced from eicosapentaenoic acid by 15-lipoxygenase (15-LO)via15(S)-HpEPE and 15S-hydroxy, 5S-HpEPE intermediatesin vitroand by isolated human M2 macrophages or polymorphonuclear (PMN) neutrophils under normoxic or hypoxic conditions. RvE4 synthesis is enhanced in M2 macrophage and neutrophil co-cultures, indicating transcellular biosynthesis by a potential 15-LO and 5-LO mechanism. It has been found in mouse inflammatory exudates. RvE4 (10 nM) increases efferocytosis of apoptotic neutrophils or senescent red blood cells (sRBCs) by human M2 macrophages under hypoxic conditionsin vitro. Intraperitoneal administration of RvE4 (100 ng/animal) inhibits increases in inflammatory exudate neutrophil infiltration in a mouse model of hemorrhagic peritonitis induced by zymosan A and thrombin. It also increases inflammatory exudate macrophage infiltration and efferocytosis of apoptotic neutrophils and/or RBCs in the same model. 1.Norris, P.C., Libreros, S., and Serhan, C.N.Resolution metabolomes activated by hypoxic environmentSci.

  • 17(R)-Resolvin D3
    Aspirin-triggered Resolvin D3,AT-RvD3,17(R)-RvD3,17-epi-Resolvin D3
    T851081427475-53-3
    17(R)-Resolvin D3 (17(R)-RvD3) is an aspirin-triggered epimer of resolvin D3, produced from docosahexaenoic acid (DHA) through the action of COX-2 in the presence of aspirin, via a 17(R)-hydroperoxy DHA (17(R)-HDHA) intermediary. Identified in mouse inflammatory exudates, 17(R)-RvD3 notably inhibits the transmigration of isolated human polymorphonuclear cells (PMNs) and fosters the efferocytosis of apoptotic PMNs by macrophages. Furthermore, in a mouse model of zymosan-induced peritonitis, 17(R)-RvD3 administration (10 ng animal) significantly curtails neutrophil infiltration into the peritoneal cavity and modulates cytokine levels by reducing IL-6 and increasing IL-10 in the inflammatory exudate. It engages GPR32, evidenced by activation in a β-arrestin reporter assay and augments phagocytosis more effectively in CHO cells overexpressing GPR32 compared to controls. Additionally, 17(R)-RvD3 enhances the clearance of etoposide-induced tumor cell debris by monocyte-derived macrophages in H460 human lung carcinoma.
