    摘要:
    抑制人鸟氨酸 δ-氨基转移酶 ( h OAT) 是治疗肝细胞癌的潜在治疗方法。在这项工作中,( S )-3-amino-4,4-difluorocyclopent-1-enecarboxylic acid (SS-1-148, 6 ) 被确定为一种有效的基于机制的h OAT灭活剂,同时显示出优于其他相关的选择性氨基转移酶(例如,GABA-AT)。进行了综合机理研究以研究6的周转和失活机制。单氟化酮 ( M10 ) 被确定为6 in h OAT 的主要代谢物。通过将h OAT 全酶晶体与如图6所示,成功捕获了M10的前体。这种与 Lys292 共价结合的宝石-二胺中间体首次在h OAT/配体晶体中观察到,验证了为6提出的周转机制。共结晶产生与6复合的h OAT,并揭示了 h 中一种新的非共价失活机制燕麦。天然蛋白质质谱法首次用于氨基转移酶灭活剂的研究,以验证配体和酶之间的非共价相互作用;共价

    Chirospecific Syntheses of Precursors of Cyclopentane and Cyclopentene Carbocyclic Nucleosides by [3 + 3]-Coupling and Transannular Alkylation
    摘要:
    A new method is reported for the preparation of enantiomerically pure (1R,2S,4S)-1-amino-2-hydroxy-4-(hydroxymethyl)cyclopentane, (1R,2R,4S)-1-amino-2-fluoro-4-(hydroxymethyl)cyclopentane, and (1R,4S)-1-amino-4-(hydroxymethyl)-2-cyclopentene, advanced precursors to carbocyclic nucleosides. The method involves initial conversion of D-serine into an aldehyde with 9-phenylfluorenyl protection at nitrogen and O-benzyl protection at oxygen. A [3 + 3]-coupling of this aldehyde with a titanium homoenolate derived from tert-butyl 3-iodopropionate gave the corresponding anti-lactone in high yield. Regioselective hydrogenolysis of the amine protecting group, accompanied by intramolecular O- to N-cyclization formed a lactam. After suitable nitrogen protection and functional group manipulation, transannular alkylation afforded the corresponding 2-benzyl- or 2-(p-methoxybenzyl)-6-hydroxy-2-azabicycclo[2.2.1]-3-heptanone. Functional group modification of the 2-benzyl analogue gave the resulting 6(S)-hydroxy and 6(R)-fluoro N-BOC imides; alternatively, the 2-(p-methoxybenzyl) analogue was converted to an N-BOC imide containing an olefinic Linkage at C-5 and C-6 of the bicycle. Subjecting each of the N-BOC imides to a reduction-deprotection sequence then afforded the desired carbocyclic analogues. The [3 + 3]-coupling method also allowed improved and expedient access to an advanced tribenzylated lactam previously used in the racemic syntheses of the hydroxylated alkaloids D-mannonolactam, deoxymannojirimycin, and prosopinone, providing a formal asymmetric synthesis of these alkaloids.

    Aminotransferases are pyridoxal 5′-phosphate-dependent enzymes that catalyze reversible transamination reactions between an amino acid and an α-keto acid, playing a critical role in cellular nitrogen metabolism. It is evident that γ-aminobutyric acid aminotransferase (GABA-AT), which balances the levels of inhibitory and excitatory neurotransmitters, has emerged as a promising therapeutic target for

  • A New Class of Conformationally Rigid Analogues of 4-Amino-5-halopentanoic Acids, Potent Inactivators of γ-Aminobutyric Acid Aminotransferase
    作者:Jian Qiu、Richard B. Silverman
    DOI:10.1021/jm9904755
    日期:2000.2.1
    Inactivation leads to covalent attachment of 2 equiv of inactivator after gel filtration; upon urea denaturation, 1 equiv of radioactivity remains bound to the enzyme. This suggests that, unlike the open-chain anlogue, the conformationally rigid analogue becomes, at least partially, attached to an active-site residue. It appears that the conformational constraint has a larger effect on inactivators that
    最近,我们发现(Qiu,J .; Pingsterhaus,JM; Silverman,RBJ Med。Chem。1999,42,4725-4728),GABA氨基转移酶(GABA-AT)灭活剂vigabatrin的构象刚性类似物不是GABA-灭活剂。在。为了确定这是否是GABA-AT灭活剂的普遍现象,合成了其他GABA-AT灭活剂的几种单和二卤素取代的构象刚性类似物(7-15),即4-氨基-5-卤代戊酸。潜在的GABA-AT灭活剂。其中四个(+)-7,(-)-9,(+)-10和(+)-15是灭活剂,尽管不如相应的开链类似物有效。氟和溴取代的类似物的最大失活速率常数k(inact)是可比的,表明CX键的断裂不是决定速率的。与该观察结果一致的发现是,[3-(2)H] -10对3.3的失活表现出氘同位素效应,这表明CH键的裂解是决定速率的步骤。氟化类似物7灭活GABA-AT的速率是相应的开链类
  • Regioselective Hydroarylations and Parallel Kinetic Resolution of Vince Lactam

    日期:2013.9.27
    Two regioselective and complementary hydroarylation reactions of an unsymmetrical cyclic olefin have been developed. The products can be transformed in one step into constrained γ‐amino acids. Regioselective arylation of Vince lactam is controlled by the choice of phosphine ligand enantiomer and the substituent on the amide nitrogen atom. The method was extended to a general regiodivergent parallel

    日期:2018.8.3
    (OV329, 1) is being developed for the treatment of epilepsy and addiction. The previous 14-step synthesis of OV329 was low yielding, involved an unselective α-elimination to form the cyclopentene, required the use of tert-butyllithium, and produced toxic selenium byproducts in the penultimate step. A new synthesis, which avoids the aforementioned issues, was carried out on large scale, reducing the step
