Mechanism of toxicity of esters of Caffeic and dihydrocaffeic acids
Ten esters each of caffeic acid and dihydrocaffeicacid have recently been synthesized. Cytotoxicity evaluations of these esters versus L1210 leukemia and MCF-7 breast cancer cells in culture have led to the delineation of substantially different QSAR for each series. The L1210 QSAR for dihydrocaffeicacidesters resembles the QSAR obtained for simple phenols and estrogenic phenols. However, the QSAR

derivatives. This work reports a novel approach to improve Candida antartica lipase B (Novozym 435) catalyzed lipophilization of phenolicacids by means of ionic liquids (IL), trioctylmethylammonium trifluoroacetate (tOMA.TFA) assisted solubilization of the substrate. In this approach, the IL plays two major roles, namely, to dissolve phenolicacids at high concentration so as to create a homogeneous system
酚酸的亲脂性衍生物可以极大地扩展其在亲脂性生物环境和食品加工中的应用,因此,开发有效的亲脂性反应体系构成了生物催化的一个有趣课题。酚酸在大多数酶良性溶剂中的低溶解度是造成亲脂性酚类衍生物酶促生产效率低下的主要原因。这项工作报告了一种新颖的方法,可通过离子液体(IL),三辛基甲基三氟乙酸铵(t)来改善南极假丝酵母脂肪酶B(Novozym 435)催化的酚酸脂化。OMA.TFA)有助于底物的溶解。在这种方法中,IL发挥了两个主要作用,即以高浓度溶解酚酸,从而与另一种底物1-辛醇形成均相系统,并对酶保持良性,从而保持生物催化剂的活性。事实证明,这本身就是一种正确的策略,因为可以提高转化率和提高生产率。结果表明,IL的用量(以1-辛醇/ t OMA.TFA的体积比表示),二氢咖啡酸(DHCA)的浓度和温度是控制反应效率的关键参数。DHCA的最大转化率是1-辛醇/吨OMA.TFA 12:1(v / v)(1-辛醇/
