아라키돈산 5리포크시겐아제 억제제

Arachidonate 5-lipoxygenase inhibitor

아라키돈산 5-립포크시제나제 억제제는 염증성 백혈구아제 생성을 담당하는 아라키돈산 5-립포크시제나 5-LOX) 효소의 작용을 늦추거나 멈추게 하는 화합물이다.백혈구 과잉생산은 천식, 알레르기 비염, 골관절염 등에 염증이 생기는 주요 원인이다.[1][2]

5-LOX 억제제의 예로는 약제 메클로페나메이트 나트륨,[3] 질류톤[3][4], 천연물 myxochelins/pseudochlin[5][6] 및 NDGA(nordihydroguaareic acid, NDGA) 등이 있다.[7]

식품에서 미량에서 발견되는 일부 화학 물질과 일부 식이 보조식품은 5-LOX를 억제하는 것으로 나타났다; 이것들은 바이칼레인,[3] 카페인산,[3] 쿠르쿠민,[3] 하이퍼포린[8][9][10], 그리고 세인트 존의 wort를 포함한다.[8][9][10]

보즈웰리아 세라타(인도 프랑킨센스)에서 발견된 생체활성 보웰산 중 하나인 아세틸-케토-베타-보스웰릭산(AKBA)이 알로스테리 억제제로서 5리폭시제네제를 강하게 억제하는 것으로 밝혀졌다.[7]보스웰리아 투여는 뇌종양에 대해 조사된 환자의 뇌 부종을 감소시키는 것으로 나타났으며 이는 5-Lipoxygenase 억제 때문인 것으로 추정된다.[11][12]

Zileuton is a specific inhibitor of 5-lipoxygenase and thus inhibits leukotriene (LTB4, LTC4, LTD4, and LTE4) formation. Both the (R)-(+)- and (S)-(-)-enantiomers are pharmacologically active as 5-lipoxygenase inhibitors in in vitro systems. Leukotrienes are substances that induce numerous biological effects including augmentation of neutrophil and eosinophil migration, neutrophil and monocyte aggregation, leukocyte adhesion, increased capillary permeability, and smooth muscle contraction. These effects contribute to inflammation, edema, mucus secretion, and bronchoconstriction in the airways of asthmatic patients. Sulfido-peptide leukotrienes (LTC4, LTD4, LTE4, also known as the slow-releasing substances of anaphylaxis) and LTB4, a chemoattractant for neutrophils and eosinophils, can be measured in a number of biological fluids including bronchoalveolar lavage fluid (BALF) from asthmatic patients.

Hyperforin is a constituent of Hypericum perforatum (St John's Wort) Hyperforin is a phytochemical produced by some of the members of the plant genus Hypericum, notably Hypericum perforatum (St John's wort). The structure of hyperforin was elucidated by a research group from the Shemyakin Institute of Bio-organic Chemistry (USSR Academy of Sciences in Moscow) and published in 1975. Hyperforin is a prenylated phloroglucinol derivative. Total synthesis of hyperforin has not yet been accomplished, despite attempts by several research groups. Hyperforin has been shown to exhibit anti-inflammatory, anti-tumor, antibiotic and anti-depressant functions

PMID 24976853. These researches are according to an investigation of the effect of H. perforatum on the NF-κB inflammation factor, conducted by Bork et al. (1999), in which hyperforin provided a potent inhibition of TNFα-induced activation of NF-κB [58]. Another important activity for hyperforin is a dual inhibitor of cyclooxygenase-1 and 5-lipoxygenase [59]. Moreover, this species attenuated the expression of iNOS in periodontal tissue, which may contribute to the attenuation of the formation of nitrotyrosine, an indication of nitrosative stress [26]. In this context, a combination of several active constituents of Hypericum species is the carrier of their anti-inflammatory activity.

PMID 24214835. Anti-inflammatory mechanisms of hyperforin have been described as inhibition of cyclooxygenase-1 (but not COX-2) and 5-lipoxygenase at low concentrations of 0.3 μmol/L and 1.2 μmol/L, respectively [52], and of PGE2 production in vitro [53] and in vivo with superior efficiency (ED50 = 1 mg/kg) compared to indomethacin (5 mg/kg) [54]. Hyperforin turned out to be a novel type of 5-lipoxygenase inhibitor with high effectivity in vivo [55] and suppressed oxidative bursts in polymorphonuclear cells at 1.8 μmol/L in vitro [56]. Inhibition of IFN-γ production, strong downregulation of CXCR3 expression on activated T cells, and downregulation of matrix metalloproteinase 9 expression caused Cabrelle et al. [57] to test the effectivity of hyperforin in a rat model of experimental allergic encephalomyelitis (EAE). Hyperforin attenuated the symptoms significantly, and the authors discussed hyperforin as a putative therapeutic molecule for the treatment of autoimmune inflammatory diseases sustained by Th1 cells.
