  Kynurenic Acid Derivatives Inhibit the Binding of Nerve Growth Factor (NGF) to the Low-Affinity p75 NGF Receptor

  摘要：

  The ability of a series of substituted kynurenic acids, thienopyridinonecarboxylic acids, and related compounds to inhibit the binding of nerve growth factor (NGF) to the p75 NGF receptor (NGFR) was evaluated in a radioligand binding assay that utilized a biotinylated derivative of the extracellular domain of p75 NGFR (p75(ext)) fixed to streptavidin-coated plastic wells. Two compounds, 6-aminokynurenic acid (5h) and the 3-methyl ester of 4,7-dihydro-2-methyl-7-oxo-thieno[3,2-b]pyridine-3,5-dicarboxylic acid (16), were found to inhibit the binding of [I-125]NGF to p75(ext) with IC50 values in the low micromolar range. Other amino-substituted kynurenic acids also possessed activity at slightly higher concentrations. Several structural features seem to be essential, including the carboxylic acid, a polar group on the benzene ring (or thiophene ring, in the case of analogues of 16), and the C-4 carbonyl group in the pyridinone ring. These compounds were also found to inhibit the binding of [I-125]NGF to its receptors in membranes from PC12 cells (which express p75 as well as trk(a) receptors for NGF) and DG44-CHO cells (transfected with full length p75 NGFR). The available data for 5h and 16 do not allow the determination of whether the effects of these compounds are mediated by their interaction with NGF or the NGF receptors.

  O-alkylated products. The behavior in basic medium of compounds 1 differs from the 3-alkoxycarbonyl-4-quinolinones (4) isomers suggesting that the position of the carboxylate group determines the regioselectivity of the reaction. DFT calculations allow us to conclude that for 3-alkoxycarbonyl-4-quinolinones, the N-alkylation would be thermodynamically and kinetically favored. But for 2-alkoxycarbonyl-4-quinolinones

  摘要 2-烷氧基羰基-4-喹啉酮(1) 与多种烷基化试剂在不同条件下反应，生成相应的O-烷基化产物。化合物 1 在碱性介质中的行为不同于 3-alkoxycarbonyl-4-quinolinones (4) 异构体，表明羧酸根的位置决定了反应的区域选择性。DFT 计算使我们得出结论，对于 3-烷氧基羰基-4-喹啉酮，N-烷基化在热力学和动力学上都是有利的。但是对于 2-烷氧基羰基-4-喹啉酮，环的 2-位侧链阻止了与连续杂原子的平面近似，从而导致更有利的 O-烷基化过渡态。O-烷基化产物的晶体结构由单晶 X 射线衍射测定。

  Synthesis of a recently discovered S-methylated quinolone natural product (1) was carried out, in addition to the production of a range of 2-substituted 4-quinolone derivatives (2–11). Two approaches were used: (i) the base-catalyzed cyclization of N-(ketoaryl)amides; (ii) attachment of the substituent to the quinolone core via a Suzuki–Miyaura cross-coupling. Also produced were a small suite of related
