    η3-C8H12)(2-PyCH2PtBu2)] (2a) and [Ir2H3(CO)(2-PyCH2PtBu2)μ-(C5H3N)CH2PtBu2}] (2c). The unexpected similarities in reactivities of 1 and 2 in this reaction, along with synthetic studies on several of our iridium intermediates, enable us to form a general proposal of the mechanisms of catalyst activation that govern the disparate reactivities of 1 and 2, respectively, in glycerol and formic acid dehydrogenation

    Wounds frequently become infected or contaminated with bacteria. Potassium oleate (C18:1K), a type of fatty acid potassium, caused >4 log colony-forming unit (CFU)/mL reductions in the numbers of Staphylococcus aureus and Escherichia coli within 10 min and a >2 log CFU/mL reduction in the number of Clostridium difficile within 1 min. C18:1K (proportion removed: 90.3%) was significantly more effective at removing Staphylococcus aureus biofilms than the synthetic surfactant detergents sodium lauryl ether sulfate (SLES) (74.8%, p < 0.01) and sodium lauryl sulfate (SLS) (78.0%, p < 0.05). In the WST (water-soluble tetrazolium) assay, mouse fibroblasts (BALB/3T3 clone A31) in C18:1K (relative viability vs. control: 102.8%) demonstrated a significantly higher viability than those in SLES (30.1%) or SLS (18.1%, p < 0.05). In a lactate dehydrogenase (LDH) leakage assay, C18:1K (relative leakage vs. control: 108.9%) was found to be associated with a significantly lower LDH leakage from mouse fibroblasts than SLES or SLS (720.6% and 523.4%, respectively; p < 0.05). Potassium oleate demonstrated bactericidal effects against various species including Staphylococcus aureus, Escherichia coli, Bacillus cereus, and Clostridium difficile; removed significantly greater amounts of Staphylococcus aureus biofilm material than SLES and SLS; and maintained fibroblast viability; therefore, it might be useful for wound cleaning and peri-wound skin.

    伤口经常会被细菌感染或污染。植酸钾(C18:1K),一种脂肪酸钾,导致金黄色葡萄球菌和大肠杆菌数量在10分钟内减少了>4个对数菌落形成单位(CFU)/毫升,并在1分钟内将难辨梭菌数量减少了>2个对数CFU/毫升。C18:1K(去除比例:90.3%)在去除金黄色葡萄球菌生物膜方面明显比合成表面活性剂十二烷基硫酸钠(SLES)(74.8%,p < 0.01)和十二烷基硫酸钠(SLS)(78.0%,p < 0.05)更有效。在水溶性四唑盐(WST)测定中,C18:1K中的小鼠成纤维细胞(BALB/3T3克隆A31)(相对存活率与对照组比:102.8%)的存活率明显高于SLES(30.1%)或SLS(18.1%,p < 0.05)。在乳酸脱氢酶(LDH)泄漏测定中,C18:1K(相对泄漏与对照组比:108.9%)与从小鼠成纤维细胞泄漏的LDH比SLES或SLS(分别为720.6%和523.4%,p < 0.05)相关联。植酸钾对金黄色葡萄球菌、大肠杆菌、蜡样芽孢杆菌和难辨梭菌等各种物种表现出杀菌效果;去除的金黄色葡萄球菌生物膜材料显著多于SLES和SLS;并保持了成纤维细胞的生存能力;因此,它可能对伤口清洁和周围皮肤有用。
  • LACTYLATE SYNTHESIS METHODS USING DILACTIDES
    申请人:Botts Jeff B.
    公开号:US20120065422A1
    公开(公告)日:2012-03-15
    The present invention involves a new synthesis route for the formation of lactylates. The method comprises reacting a dilactide with a compound comprising a hydroxy group. This reaction is preferably carried out in the presence of a cation or other source of alkalinity. Preferred compounds comprising a hydroxy group include any fatty acid and fatty acid alcohol (particularly C 1 -C 26 fatty acid chains). Preferred cations include cations of Group I and II metals, with sodium, calcium, and potassium cations being particularly preferred. The inventive reactions proceed much more rapidly than prior art lactylate synthesis reactions, and can be used to form 1-, 2-, 3-, 4-, and 5-lactylates.
    本发明涉及一种用于合成乳酰酸盐的新合成途径。该方法包括将二乳酸酯与含有羟基的化合物发生反应。该反应最好在存在阳离子或其他碱性来源的情况下进行。含有羟基的化合物包括任何脂肪酸和脂肪醇(尤其是碳链为C1-C26的脂肪酸链)。优选的阳离子包括I和II族金属的阳离子,其中特别优选的是钠、钙和钾阳离子。这种创新的反应比现有技术中的乳酰酸盐合成反应快得多,并可用于形成1-、2-、3-、4-和5-乳酰酸盐。
