  Characterization of hydroxy fatty acid dehydrogenase involved in polyunsaturated fatty acid saturation metabolism in Lactobacillus plantarum AKU 1009a

  摘要：

  Hydroxy fatty acid dehydrogenase, which is involved in polyunsaturated fatty acid saturation metabolism in Lactobacillus plantarum AKU 1009a, was cloned, expressed, purified, and characterized. The enzyme preferentially catalyzed NADH-dependent hydrogenation of oxo fatty acids over NAD(+)-dependent dehydrogenation of hydroxy fatty acids. In the dehydrogenation reaction, fatty acids with an internal hydroxy group such as 10-hydroxy-cis-12-octadecenoic acid, 12-hydroxy-cis-9-octadecenoic acid, and 13-hydroxy-cis-9-octadecenoic acid served as better substrates than those with alpha- or beta-hydroxy groups such as 3-hydroxyoctadecanoic acid or 2-hydroxyeicosanoic acid. The apparent Km value for 10-hydroxy-cis-12-octadecenoic acid (HYA) was estimated to be 38 mu M with a k(cat) of 7.6 x 10(-3) s(-1). The apparent K-m value for 10-oxo-cis-12-octadecenoic acid (KetoA) was estimated to be 1.8 mu M with a k(cat) of 5.7 x 10(-1) s(-1). In the hydrogenation reaction of KetoA, both (R)- and (S)-HYA were generated, indicating that the enzyme has low stereoselectivity. This is the first report of a dehydrogenase with a preference for fatty acids with an internal hydroxy group. (C) 2015 Elsevier B.V. All rights reserved.

  As part of a program to establish structure-activity relationships for vanilloids, analogs of the pungent principle capsaicin, the alkyl chain portion of the parent structure (and related compounds derived from homovanillic acid) was varied. In antinociceptive and antiinflammatory assays (rat and mouse hot plate and croton oil-inflamed mouse ear), compounds with widely varying alkyl chain structures

  作为建立香草醛的结构活性关系的程序的一部分，辛辣成分辣椒素的类似物，母体结构的烷基链部分（以及衍生自高香草酸的相关化合物）发生了变化。在抗伤害感受和抗炎试验（大鼠和小鼠热板以及巴豆油刺激的小鼠耳朵）中，具有广泛变化的烷基链结构的化合物具有活性。短链化合物在上述测定中通过全身给药具有活性，但它们保留了辣椒素的高刺激性和急性毒性特征。相比之下，长链顺式不饱和物NE-19550（香草基油酰胺）和NE-28345（油基单香草酰胺）具有口服活性，刺激性较低，并且比辣椒素的急性毒性小。

  The invention relates to a method for the synthesis of amino acids/esters of general formula NH 2 —(CH 2 ) n —COOR in which n is an integer between 5 and 14, and R is either H or an alkyl radical including from 1 to 4 carbon atoms, from natural long-chain mono-unsaturated fatty acids or esters including at least 10 adjacent carbon atoms per molecule, said method comprising: first converting, if necessary, said natural long-chain fatty acid or ester into a monounsaturated fatty acid/ester of general formula R 1 —(CH 2 ) m —CH═CH—(CH 2 ) p —COOR in which R 1 is H, CH 3 or a COOR radical, m is an integer between 0 and 14 and p is an integer between 2 and 11, then submitting the latter to a crossed catalytic metathesis reaction with a compound of formula R 2 —CH═CH—R 3 in which R 2 is either H or CN and R 3 is CN or CH 2 NH 2 , provided that if R 2 is CN, R 3 can be only CN, and finally converting the resulting product of the general formula R 3 —CH═CH—(CH 2 ) p —COOR into an amino-acid, either by hydrogenation, or by hydrogenation of the triple terminal bond, or by amination of the double terminal bond.

  本发明涉及一种合成通式为NH2—(CH2)n—COOR的氨基酸/酯的方法，其中n为5至14之间的整数，R为H或包括1至4个碳原子的烷基基团，所述方法包括：首先，如果必要，将天然长链脂肪酸或酯转化为通式为R1—(CH2)m—CH═CH—(CH2)p—COOR的单不饱和脂肪酸/酯，其中R1为H，CH3或COOR基团，m为0至14之间的整数，p为2至11之间的整数；然后，将后者与通式为R2—CH═CH—R3的化合物进行交叉催化复分解反应，其中R2为H或CN，R3为CN或CH2NH2，如果R2为CN，则R3只能为CN；最后，将得到的通式为R3—CH═CH—(CH2)p—COOR的产品转化为氨基酸，可以通过氢化，或通过氢化末端的三键，或通过末端的双键的氨基化来实现。
