    探究 AIR 羧化酶紧密结合抑制剂的作用机制
    摘要:
    氨基咪唑核糖核苷酸 (AIR) 羧化酶催化嘌呤中间体 4-羧基-5-氨基咪唑核糖核苷酸 (CAIR) 的合成。以前,我们已经表明化合物 4-硝基-5-氨基咪唑核糖核苷酸 (NAIR) 是一种缓慢、紧密结合的酶抑制剂,Ki 为 0.34 nM。NAIR 的结构属性和缓慢、紧密的结合特性表明该化合物是一种过渡态或反应性中间体类似物。然而,尚不清楚 NAIR 的哪些分子特征有助于 AIR 羧化酶的两种拟议机制中的任何一种的模拟特性。为了获得关于 NAIR 对 AIR 羧化酶的有效抑制机制的更多信息,制备并评估了一系列杂环类似物。我们发现所有化合物都是比 NAIR 更弱的抑制剂,并且 CAIR 类似物不是该酶的替代底物。令人惊讶的是,NAIR 结构的相当细微的变化会导致结合亲和力的深刻变化。酶中间体和这些抑制剂的计算研究表明,NAIR 显示出类似于提议的反应中间体的静电势表面。结果表明 AIR 羧

  • Isatins Inhibit N<sup>5</sup>-CAIR Synthetase by a Substrate Depletion Mechanism

    new agents is de novo purine biosynthesis as studies have shown that bacteria and lower eukaryotes synthesize purines differently than humans. Microorganisms utilize two enzymes, N5-CAIR synthetase and N5-CAIR mutase, to convert 5-aminoimidazole ribonucleotide (AIR) into 4-carboxy-5-aminoimidazole ribonucleotide (CAIR) through the intermediate N5-carboxy-5-aminoimidazole ribonucleotide (N5-CAIR).

    抗生素耐药性感染的持续增加,加上新的抗菌药物渠道有限,凸显了对开发新的抗菌药物的迫切需求。从头研究嘌呤的生物合成是新药的一种潜在途径,因为研究表明细菌和低等真核生物合成嘌呤的方法与人类不同。微生物利用N5-CAIR合成酶和N5-CAIR突变酶这两种酶通过中间N5-羧基-5-氨基咪唑核糖核苷酸(N5- CAIR)。相反,脊椎动物通过AIR羧化酶直接将AIR转换为CAIR。针对N5-CAIR合成酶的高通量筛选确定了一组具有2,3-吲哚二酮(isatin)核心抑制该酶的化合物。虽然最初的研究表明isatins通过非竞争性机制抑制酶,但在这里我们显示isatins通过底物耗竭机制抑制N5-CAIR合成酶。出乎意料的是,我们发现Isatin与底物AIR迅速且可逆地反应。反应速率取决于Isatin苯基部分上的取代基,其中5-和7-Bromoisatin的速度快于4-Bromoisatin。这些研究表明

    A versatile synthetic route to 3-deaza-3-haloinosines 6-8 and 46, -adenosines 15-17 and 64, and -guanosines 25, 26, and 52 is described. 3-Deaza-3-chloro-, -bromo-, and -iodopurine ribonucleosides can be synthesized by treating the 3-deazapurine ribonucleosides with N-halosuccinimides. For the synthesis of 3-deaza-3-fluoropurine ribonucleosides, 5-formylimidazole-4-carboxamide ribosides 34 and 35 prepared from 5-iodoimidazole-4-carboxamide derivatives 29 and 31 were us ed as the key intermediates. The reaction of 34 and 35 with lithium (trimethylsilyl)acetylide and sodium cyanide, respectively, followed by appropriate manipulations gave 3-deaza-3-fluoroinosine derivative 46 and 3-deaza-3-fluoroguanosine derivative 52. 3-Deaza-3-fluoroadenosine (64) was also synthesized by selective reductive deamination of 4,6-diamino-7-fluoroimidazo[4,5-c]pyridine derivative 51, followed by deprotection. A conformational analysis using H-1 NMR and NOE experiments showed that the introduction of halogens (chloro, bromo, and iodo) into the 3-position of 3-deazapurine ribonucleosides forced fixation of the glycosyl torsion angle in the anti region, but did not-abnormally influence sugar puckering. On the other hand, 3-deaza-3-fluoropurine ribonucleosides should rotate freely around the glycosyl bond.

    A mild and versatile chemical conversion of the 4-carboxamide group of 5-amino-1-beta-D-ribofuranosylimidazole-4-carboxamide (AICA-riboside) is described. The reaction of protected AICA-riboside with di-tert-butyl dicarbonate gave 5-[N,N-di-(tert-butoxycarbonyl)]-amino-1-(5-O-tert-butyldimethylsilyl-2,3-O-isopropylidene-beta-D-ribofurnaosyl)imidazole-4-[N,N-di-(tert-butoxycarbonyl)]carboxamide in 71% yield. The resulting tetraBoc derivative was treated with sodium methoxide, benzylamine, or acetonitrile anion to give the corresponding methyl ester, N-benzylcarboxamide, or cyanoacetyl products. The 4-cyanoacetylimidazole derivative was converted into 1-deazaguanosine via an intramolecular cyclization. (C) 2000 Elsevier Science Ltd. All rights reserved.
