(±)15-HEPE
(±)15-HEPE ((±)15-hydroxyeicosapentaenoic acid; 15-OHEPA) is a racemic mixture of monohydroxy fatty acids, including 15(R)-HEPE and 15(S)-HEPE (HY-130675A). (±)15-HEPE exhibits anti-inflammatory, anti-allergic, and antibacterial activities. (±)15-HEPE rapidly kills S. aureus and inhibits the growth of P. acnes, but has no bactericidal effect. (±)15-HEPE is a PPARγ agonist that inhibits mast cell degranulation. (±)15-HEPE is also a 5-lipoxygenase inhibitor with an IC50 of 28 μM, reducing the production of pro-inflammatory leukotrienes. (±)15-HEPE can be used for research on acne vulgaris, allergic rhinitis, and psoriasis.

In Vitro
(±)15-HEPE (up to 4096 mg/L; 18-48 h) has an MIC50 of 1024 mg/L and an MBC50 of 2048 mg/L against ten tested S. aureus isolates[1].
(±)15-HEPE (1024 mg/L; 15 min) kills S. aureus ATCC43300 to no detectable CFU within 15 min[1].
(±)15-HEPE (18-20 h) exhibits synergistic effects with BPO (mean FIC 0.44) and NEO (mean FIC 0.34) against S. aureus ATCC43300[1].

-
Cell Line:Staphylococcus aureus ATCC43300
-
Concentration:1024 mg/L
-
Incubation Time:15 min
-
Result:Exhibited rapid bactericidal effects against S. aureus, and no viable bacteria were detected within 15 minutes of initial exposure.
In Vivo
(±)15-HEPE (10 ng; i.n.; once daily 5 minutes before OVA challenge; combined with GW9662 1 mg/kg intraperitoneally 30 minutes earlier) attenuates allergic rhinitis in mice; antagonism of PPARγ with GW9662 (HY-16578) counteracts this effect[2].

-
Animal Model:C57BL/6J (female, 6-7 weeks of age)[2]
-
Dosage:10 ng
-
Administration:i.n.; once daily 5 min before OVA challenge; from the first day of nasal challenge
-
Result:Reduced sneezing frequency in OVA-challenged mice compared with mock OVA-challenged controls.
-
Animal Model:C57BL/6J (female, 6-7 weeks of age)[2]
-
Dosage:10 ng
-
Administration:i.n.; once daily 5 min before OVA challenge; days 5-10
-
Result:In mice with established allergic rhinitis, little increase in sneezing frequency occurred over the administration period, whereas the vehicle group increased in sneezing frequency.
-
Animal Model:C57BL/6J (female, 6-7 weeks of age)[2]
-
Dosage:10 ng; GW9662 (1 mg/kg)
-
Administration:i.n.; once daily 5 min before OVA challenge; intraperitoneal GW9662 daily 30 min before
-
Result:Reduced sneezing frequency compared with vehicle, and GW9662 co-administration nullified the reduction, with sneezing frequency returning to vehicle-like levels.
