    Bisubstrate Analogue Inhibitors of 6-Hydroxymethyl-7,8-dihydropterin Pyrophosphokinase:  Synthesis and Biochemical and Crystallographic Studies
    摘要:
    6-Hydroxymethyl-7,8-dihydropterin pyrophosphokinase (HPPK) catalyzes the transfer of pyrophosphate from ATP to 6-hydroxymethyl-7,8-dihydropterin (HP), leading to the biosynthesis of folate cofactors. Like other enzymes in the folate pathway, HPPK is an ideal target for the development of antimicrobial agents because the enzyme is essential for microorganisms but is absent from human and animals. Three bisubstrate analogues have been synthesized for HPPK and characterized by biochemical and X-ray crystallographic analyses. All three bisubstrate analogues consist of a pterin, an adenosine moiety, and a link composed of 2-4 phosphoryl groups. P-1-(6-Hydroxymethylpterin)-P-2-(5 ' -adenosyl)diphosphate (HP(2)A, 5) shows little affinity and inhibitory activity for E. coli HPPK, P-1-(6-Hydroxymethylpterin)-P-4-(5 ' -adenosyl)triphosphate (H(P)3A, 6) shows moderate affinity and inhibitory activity with K-d = 4.25 muM in the presence of Mg2+ and IC50 = 1.27 muM. P-1-(6-Hydroxymethylpterin)-P-4-(5 ' -adenosyl)tetraphosphate (HP(4)A, 7) shows the highest affinity and inhibitory activity with K-d = 0.47 muM in the presence of Mg2+ and IC50 = 0.44 muM The affinity of MgHP(4)A for HPPK is similar to 116 and 76 times higher than that of MgADP and 6-hydroxymethylpterin, respectively. The crystal structure of HPPK in complex with 7 (HPPK MgHP4A) has been determined at 1.85 Angstrom resolution with a crystallographic R factor of 0.185. The crystal structure shows that 7 occupies both HP- and ATP-binding sites and induces significant conformational changes in HPPK. The biochemical and structural studies of the bisubstrate analogues indicate that the bisubstrate analogue approach can produce more potent inhibitors for HPPK and the minimum length of the link for a bisubstrate analogue is similar to7 Angstrom.

  • Process For The Preparation Of Optically Pure Tetrahydropterins And Derivatives, And Specifically Of Optically Pure Tetrahydrofolic Acid And Derivatives Thereof, By Stereospecific Hydrogenation
    申请人:MULLER Hans Rudolf

    公开(公告)日:2008-12-11
    Process for the preparation of tetrahydropterin and tetrahydropterin derivatives by hydrogenating pterin and pterin derivatives with hydrogen in the presence of a hydrogenating catalyst, in which the hydrogenation is carried out in a polar reaction medium and metal complexes that are soluble in the reaction medium are employed as the hydrogenation catalysts. The process is suited to the hydrogenation, particularly asymmetric hydrogenation, of folic acid, folio acid salts, folio acid esters, folio acid ester salts or dihydroforms thereof, with the proviso that in the event of using folic acid, carboxylic acid salts thereof or dihydroforms thereof the reaction medium is aqueous, and in the event of using folic acid esters, folic acid ester salts or dihydroforms thereof the reaction medium is an alcohol. The process opens up straightforward access to achiral and chiral pterin derivatives.

    叶酸途径是治疗人类寄生虫和细菌感染的公认干预点。但是,由于疾病相关的突变,靶向二氢蝶呤合酶(DHPS)和二氢叶酸还原酶(DHFR)的治疗功效有所降低。这已经引起人们对该临床验证途径上其他酶靶标的兴趣,包括6-羟甲基-7,8-二氢蝶呤焦磷酸激酶(HPPK)。设计靶向该酶的分子的一个挑战是反应的确切机理和活性位点残基的作用尚不完全清楚。在这项研究中,我们报告了使用混合量子力学/分子力学(QM / MM)方法对天然底物的催化途径进行的第一个理论分析。已经研究了与三种提议的通用碱基相关的反应谱,以及两种突变酶即R92A和R82A的谱。我们确定R92为野生型反应中的一般碱基。预测的障碍与观察到的实验非常吻合获得的野生型和突变蛋白的k cat值。
