4,5-EET / Epoxyeicosatrienoic aside: Epoxyeicosatrienoic acide cyangwa EETs yerekana molekile zakozwe mubwoko butandukanye bwingirabuzimafatizo na metabolism ya acide arachidonic hamwe na sisitemu yihariye ya Cytochrome P450 yitwa cytochrome P450 epoxygenase. Iyi eicosanoide idafite classique muri rusange ni iyigihe gito, ihindurwa byihuse kuva muri epoxide ikagera kuri acide idakora cyane cyangwa idakora dihydroxy-eicosatrienoic acide (diHETrEs) na enzyme ikwirakwizwa cyane, Soluble epoxide hydrolase (sEH), nayo yitwa Epoxide hydrolase 2. EETs ikora. nkibikorwa byigihe gito, imisemburo ngufi; ni ukuvuga, bakorera mugace kugirango bagenzure imikorere ya selile zibibyara cyangwa za selile zegeranye. EETs yakozweho ubushakashatsi cyane mubyitegererezo by'inyamaswa aho zigaragaza ubushobozi bwo kugabanya umuvuduko w'amaraso bishoboka ko a) itera vasorelaxation ya arterial na b) kubuza impyiko kugumana imyunyu n'amazi kugirango igabanye umuvuduko w'amaraso. Muri ubu buryo, EET irinda indwara ziterwa na arterial nkumutima ndetse nubwonko bwubwonko ntibiterwa gusa nigikorwa cyo kurwanya hypertension gusa ahubwo birashoboka ningaruka zabyo zo kurwanya indwara zifata imiyoboro y'amaraso, kubuza gukora platine bityo no gutembera kw'amaraso, na / cyangwa kuzamura kwabo gukuraho pro-fibrinolytike yo gukuraho amaraso. Kubijyanye n'ingaruka zabyo kumutima, EET bakunze kwita umutima-urinda. Kurenga kuri ibyo bikorwa byumutima nimiyoboro y'amaraso bishobora gukumira indwara zinyuranye z'umutima-damura, ubushakashatsi bwagize uruhare muri EET mukuzamuka kwindwara yubwoko bumwe na bumwe bwa kanseri ndetse no mubitekerezo bya physiologique kandi bishoboka ko byatewe nububabare bwa neuropathique. Mugihe ubushakashatsi kugeza ubu bwerekana ko EETs, EET ikora epoxygenase, hamwe na EET idakora sEH irashobora gukoreshwa muguhashya indwara zitandukanye zabantu, ubushakashatsi bwamavuriro ntiburabigaragaza. Kumenya uruhare rwa EETS mu ndwara zabantu biragoye cyane kubera ubwinshi bwa epoxygenase ya EET ikora, umubare munini wa epoxygenase uterwa na aside arachidonic, hamwe nibikorwa byinshi, bimwe muribi bishobora kuba ari indwara cyangwa bikomeretsa , ko EET ifite.
