山楂酸 用途与合成方法
西班牙格拉纳达大学的科学家发现山楂酸能够抑制丝氨酸蛋白酶，而艾滋病病毒正是利用这种酶将自身从被感染的细胞中向外部释放，扩散至病毒感染者全身。
山楂酸具有抗肿瘤、抗艾滋病病毒作用，能使艾滋病病毒在体内扩散的几率降低80%。 本品应在低温干燥保存，特殊产品要在氮气下保存，长时间保存不当含量会有所降低。 Maslinic acid 可抑制 NF-κB p65 的 DNA 结合活性, 并消除 IκB-α 磷酸化。

NF-κB

Maslinic acid (MA) inhibits LPS-induced NF-κB translocation to nucleus and phosphorylation of IκB-α. Maslinic acid has also been reported to suppress NF-κB regulated osteoclastogenesis in bone marrow monocytes and inhibit TNF-α-induced NF-κB activity and its downstream genes’ expression in pancreatic cancer cells. To confirm if the anti-inflammatory effects of olive pomace extracts (OPEs) inRAW264.7 cells can be attributed to Maslinic acid, dose-dependence experiments determined the effective concentration of Maslinic acid to be 10-20 μM. 20 μM Maslinic acid significantly suppresses TNF-α production and inhibits IL-1, IL-6, and COX-2 mRNA expression in RAW 264.7 cell. Maslinic acid (at 10 and 20 μM) significantly suppresses the DNA-binding activity of NF-κB p65 in LPS-induced RAW 264.7 cells. Pretreatment with Maslinic acid significantly reduces the LPS-induced phosphorylation of IκB-α.
Paw swelling is alleviated when mice are administered with 200 mg/kg Maslinic acid (MA), significantly suppressing inflammation, compared to the carrageenan induced control group, 4 h after λ-carrageenan injection (0.91±0.51 mm and 1.79±0.4 mm, respectively).
药理药效:抗肿瘤、抗艾滋病病毒、抗炎、抗菌等作用
