  酪醇和羟基酪醇衍生物作为抗锥虫和抗疟药

  摘要：

  锥虫病和利什曼病一直是非洲国家健康和发展的真正挑战。现有疗法具有相当大的副作用并增加了寄生虫的抵抗力。我们已经测量了天然酚，酪醇（TYR）和羟基酪醇（HT）以及它们的一些酯和代谢物的抗胰锥虫和抗疟疾活性。我们发现针对布鲁氏锥虫的有效IC 50值用于HT癸酸酯和HT十二酸酯（分别为0.6和0.36μM）。这表示相对于HT的活性大大增加（分别为79和132倍）。此外，两种化合物均对非肿瘤性人类细胞系MRC-5（分别为118和106）表现出高选择性。然后，我们合成了一个有针对性的化合物库，以探索结构活性。我们发现HT癸酸酯和HT十二酸酯的醚和硫脲类似物在低微摩尔范围内也显示出针对布鲁氏杆菌的IC 50值。总之，二邻苯酚环和中等大小的烷基链对于活性至关重要，而它们之间化学键的性质似乎不太重要。

  Our group has recently observed a nonlinear tendency in antioxidant capacity of different hydroxytyrosol fatty acid esters in fish oil-in-water emulsions, where a maximum of antioxidant efficiency appeared for hydroxytyrosol octanoate. These results appear to disagree with the antioxidant polar paradox. Because the physical location of the antioxidants in an oil water interface has been postulated as an important factor in explaining this behavior, we have prepared a series of tyrosol and hydroxytyrosol fatty acid esters with different chain length and studied their surface-active properties in water, because these physicochemical parameters could be directly related to the preferential placement at the interface. We have found that tyrosol and hydroxytyrosol fatty acid esters are relevant surfactants when the right hydrophilic-lipophilic balance (HLB) is attained and, in some cases, as efficient as emulsifiers commonly used in industry, such as Brij 30 or Tween 20. Moreover, a nonlinear dependency of surfactant effectiveness is observed with the increase in chain length of the lipophilic antioxidants. This tendency seems to fit quite well with the reported antioxidant activity in emulsions, and the best antioxidant of the series (hydroxytyrosol octanoate) is also a very effective surfactant. This potential explanation of the nonlinear hypothesis will help in the rational design of antioxidants used in oil-in-water emulsions.

  Lipase-catalyzed synthesis of eight fatty acid tyrosyl esters (TyC(2) to TyC(18:1)) was investigated using non commercial lipases from Rhizopus oryzae and Staphylococcus xylosus immobilized onto CaCO3. The monomolecular film technique was used to compare the ability of the various synthesized tyrosyl fatty acid esters to form a stable monolayer at the air/water interface and their capacity to interact with a phospholipid monolayer. The measurements of surface pressure versus the molecular area shows that, in contrast to tyrosol esterified with short and medium chains (acetic (TyC(2)), propionic (TyC(3)), caprylic (TyC(8)) and capric (TyC(10)) acids), tyrosol esterified with long chains: lauric (TyC(12)), palmitic (TyC(16)), stearic (TyC(18)) and oleic (TyC(18:1)) acids are able to form a stable monolayer at the air/water interface. A direct correlation was observed between the length of the saturated acyl chain of the derivatives and their corresponding collapse pressures. The presence of unsaturation reduces the collapse pressure value. The interaction of tyrosyl esters with a phospholipid monolayer was studied and the critical surface pressure (pi(c)) of each ester was determined. Only medium and long chain (TyC(8) to TyC(18:1)) derivatives esters were found to interact efficiently with DiC(12)PC film. (C) 2012 Elsevier B.V. All rights reserved.

  Recently, tyrosol has gained attention as a result of its many pharmacological properties and due to the fact that it can be isolated from cheap and abundant resources. Lipophilic tyrosyl esters, which are scarce in nature, have proven in certain cases to acquire improved biological activity compared to tyrosol itself, increasing their potential use in the food and cosmeceutical industries. The enzymatic approach for the synthesis of such esters has prevailed, as it is "green", compared to chemical practices. We hereby report the enzymatic synthesis of tyrosyl esters of various aliphatic fatty acids performed by a recombinant cutinase from Fusarium oxysporum (FoCut5a). The reaction system used consists of an aqueous phase saturated with the corresponding fatty-acid vinyl ester, which played the role of the acyl donor. We also proceeded to the study of several parameters on the yield of the tyrosyl butyrate ester synthesis. The maximum yield achieved was 60.7% after 4 h at 20 degrees C, in pH 7.0, with initial tyrosol concentration of 12.5 mM and using 5 mu g FoCut5a mL(-1) reaction as catalyst. The optimum reaction conditions can be considered mild, highlighting the environmentally friendly nature of this reaction, along with the fact that there are not any harmful reagents involved. Additionally, the use of two thermodynamic models, Conductor-like Screening Model for Real Solvents (COSMO-RS) and UNIquac Functional-group Activity Coefficients (UNIFAC), were employed for the prediction of reactants' and products' solubilities and their distribution in the reaction biphasic system, aiming to correlate the reaction yields with these important thermodynamic quantities and understand the ability of this enzymatic reaction in synthesizing tyrosyl esters.

  Existing treatments have considerable side effects and increase resistance of the parasites. We have measured antitrypanosomal and antileishmanial activity of natural phenols, tyrosol (TYR) and hydroxytyrosol (HT) and several of their esters and metabolites. We found significant IC50 values against Trypanosoma brucei for HT decanoate ester and HT dodecanoate ester (0.6 and 0.36 μM, respectively). This represents
