5hete

5(R)-HETE is a rare lipoxygenase product of arachidonic acid. Nearly all plant and animal 5-LOs produce 5(S)-HETE, but the presence of a 5(R)-LO and the synthesis of 5(R)-HpETE and 5(R)-HETE have been confirmed in oocytes of the bivalve mollusk, S. solidissima. 5(R)-HETE is more potent than the (S)-enantiomer as a chemotactic agent for human neutrophils.

5(S)-HETE lactone is a cyclic ester formed by acid-catalyzed nucleophilic addition of the C-5 hydroxyl to the C-1 carboxyl of 5(S)-HETE. The ability of (±)5-HETE lactone to inhibit rat basophilic leukemia cell 5-lipoxygenase (IC50 = 27 μM) may be entirely due to the 5(S) isomer, but the enantiomers have not been tested separately.

5-HETE ((±)-5-HETE) 为花生四烯酸氧化衍生的脂肪酸，包括 5(S)-HETE 与 5(R)-HETE 的混合体。该化合物作为有效的聚集剂，能够引发中性粒细胞聚集，其IC50值达到 200 nM。

(±)15-HETE is an alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs[1].

(±)5-HETE, a monohydroxy fatty acid, emerges from the non-enzymatic oxidation of arachidonic acid and is one of six such derivatives. Its methyl ester variant exhibits no unique biological activity and serves as a provided standard. This methyl ester can also be present in oxidatively degraded polyunsaturated fatty acid (PUFA) methyl esters.
