Angiotensin II is a hormone that plays an important role in regulating blood pressure. Elevated levels of angiotensin II are implicated in inducing and maintaining hypertension, and also in the development of atherosclerosis. Both of these effects are mediated by the angiotensin II type 1 (AT1) receptor. Losartan is a mammalian AT1 receptor antagonist with a Ki value of 5-20 nM. In humans, losartan effectively controls hypertension while protecting renal function. Nitric oxide (NO) causes vasodilation and also inhibits platelet and neutrophil aggregation in the endothelium. NO-losartan A possesses similar anti-hypertensive effects to losartan, with the addition of the vasodilating effects of NO release.

Resolvin E2 (RvE2) is a member of the specialized pro-resolving mediator (SPM) family of bioactive lipids.1It is produced from eicosapentaenoic acidviaan 18-HEPE intermediate, which is formed by aspirin-acetylated COX-2-mediated oxidation of EPA, by 5-lipoxygenase (5-LO) in human polymorphonuclear (PMN) neutrophils.2,3RvE2 (20 ng/animal) inhibits increases in inflammatory exudate neutrophil infiltration in a mouse model of peritonitis induced by zymosan A .3Hepatic RvE2 levels are increased in mice fed normal chow, as well as in a mouse model of high-fat diet-induced non-alcoholic fatty liver disease (NAFLD), by dietary supplementation with EPA.4Plasma levels of RvE2 are increased by dietary supplementation with fish oil containing ω-3 polyunsaturated fatty acids (PUFAs) in patients with peripheral artery disease or chronic kidney disease.1,5,6 1.Chiang, N., and Serhan, C.N.Specialized pro-resolving mediator network: An update on production and actionsEssays Biochem.64(3)443-462(2020) 2.Tjonahen, E., Oh, S.F., Siegelman, J., et al.Resolvin E2: Identification and anti-inflammatory actions: Pivotal role of human 5-lipoxygenase in resolvin E series biosynthesisChemistry & Biology131193-1202(2006) 3.Sungwhan, F.O., Pillai, P.S., Recchiuti, A., et al.Pro-resolving actions and stereoselective biosynthesis of 18S E-series resolvins in human leukocytes and murine inflammationJ.

Sialyl-Lewis X (sLeX), a sialylated fucosylated tetrasaccharide and endogenous antigen, serves as a high-affinity ligand for selectins (E-, P-, and L-selectin)[1]. It interacts with ELAM-1 and CD62, consequently inhibiting CD62-mediated neutrophil recruitment to inflammation sites[2].

Resolvin conjugate in tissue regeneration 1 (RCTR1) is a specialized pro-resolving mediator (SPM) biosynthesized from docosahexaenoic acid by isolated human macrophages and apoptotic polymorphonuclear (PMN) neutrophils.1It has been found in human spleen and bone marrow.2RCTR1 is produced via lipoxygenase-mediated oxidation of DHA to 7(S)-8-epoxy-17(S)-HDHA, which is conjugated to glutathione.1,2,3RCTR1 (10 nM) increases phagocytosis ofE. colior apoptotic neutrophils in isolated human monocyte-derived macrophages.2It decreases chemotaxis induced by leukotriene B4in isolated human neutrophils when used at a concentration of 10 nM. RCTR1 (1 and 10 nM) accelerates tissue regeneration in planaria. Intraperitoneal administration of RCTR1 (100 ng/animal) shortens the inflammatory resolution period and decreases inflammatory exudate neutrophil infiltration in a mouse model ofE. coli-induced peritonitis. 1.Dalli, J., Ramon, S., Norris, P.C., et al.Novel proresolving and tissue-regenerative resolvin and protectin sulfido-conjugated pathwaysFASEB J.29(5)2120-2136(2015) 2.de la Rosa, X., Norris, P.C., Chiang, N., et al.Identification and complete stereochemical assignments of the new resolvin conjugates in tissue regeneration in human tissues that stimulate proresolving phagocyte functions and tissue regenerationAm.

Protectin D1 (also known as neuroprotectin D1 when produced in neuronal tissues) is a DHA-derived dihydroxy fatty acid that exhibits potent protective and anti-inflammatory activities. 10(S),17(S)-DiHDHA is a DHA metabolite, also referred to as protectin DX (PDX). It is produced by an apparent double lipoxygenase (LO)-mediated reaction in murine peritonitis exudates, in suspensions of human leukocytes, or by soybean 15-LO incubated with DHA. It differs from protectin D1 with respect to the stereochemistry of the C-10 hydroxyl and the double bond configuration at the 13 and 15 positions. 10(S),17(S)-DiHDHA blocks neutrophil infiltration in murine peritonitis by 20-25% at a dose of 1 ng mouse. It also inhibits platelet activation by both impairing thromboxane (TX) synthesis and TX receptor activation.
