    Substrate Specificity and Regioselectivity of Δ12 and ω3 Fatty Acid Desaturases fromSaccharomyces kluyveri
    摘要:
    Δ12和ω3脂肪酸去饱和酶是多不饱和脂肪酸(PUFAs)合成中的关键酶,PUFAs是膜甘油脂的重要成分,也是许多生物中信号分子的前体。在这项研究中,我们确定了来自酿酒酵母(Saccharomyces kluyveri)的Δ12和ω3脂肪酸去饱和酶(Sk-FAD2和Sk-FAD3)底物特异性和区域选择性。通过在酿酒酵母(Saccharomyces cerevisiae)中的异源表达发现,Sk-FAD2将C16–20单不饱和脂肪酸转化为二不饱和脂肪酸,通过在ν+3位置引入第二个双键,而Sk-FAD3则识别C18和C20的ω3位置。此外,主要磷脂的脂肪酸分析表明,Sk-FAD2和Sk-FAD3对磷脂中脂肪酰基的脂质极性头部或sn-位点没有强的底物特异性。

    Liposomal Delivery of Diacylglycerol Lipase-Beta Inhibitors to Macrophages Dramatically Enhances Selectivity and Efficacy in Vivo
    摘要:
    Diacylglycerol lipase beta (DAGL beta) hydrolyzes arachidonic acid (AA)-containing diacylglycerols to produce bioactive lipids including endocannabinoids and AA-derived eicosanoids involved in regulation of inflammatory signaling. Previously, we demonstrated that DAGL beta inactivation using the triazole urea inhibitor KT109 blocked macrophage inflammatory signaling and reversed allodynic responses of mice in inflammatory and neuropathic pain models. Here, we tested whether we could exploit the phagocytic capacity of macrophages to localize delivery of DAGL beta inhibitors to these cells in vivo using liposome encapsulated KT109. We used DAGL beta-tailored activity-based probes and chemical proteomic methods to measure potency and selectivity of liposomal KT109 in macrophages and tissues from treated mice. Surprisingly, delivery of similar to 5 mu g of liposomal KT109 was sufficient to achieve similar to 80% inactivation of DAGL beta in macrophages with no apparent activity in other tissues in vivo. Our macrophage-targeted delivery resulted in a >100-fold enhancement in antinociceptive potency compared with free compound in a mouse inflammatory pain model. Our studies describe a novel anti-inflammatory strategy that is achieved by targeted in vivo delivery of DAGL beta inhibitors to macrophages.
