    名称:
    Inverse agonists at the polyamine-sensitive modulatory site of the NMDA receptor: 50-fold increase in potency by insertion of an aromatic ring into an alkanediamine chain
    摘要:
    Polyamines like spermine and spermidine increase the opening frequency of the NMDA receptor associated ion channel and, as a consequence, specific binding of non-saturating concentrations of the channel radioligand [H-3]MK-801. Compounds exhibiting the contrary effect have been described as polyamine inverse agonists, with 1,12-dodecanediamine (N-12-N) being one of the most specific ones (IC50 16.5 mu M). Here we describe the synthesis of a series of long-chain alkanediamines, with a thiophene nucleus inserted at various positions, and report the discovery of 5-(4-aminobutyl)-2-thiopheneoctanamine (N-4-T-8-N), which inhibited specific binding of [H-3]MK-801 by 50 % at 0.33 mu M. In the presence of 100 mu M of spermine, 4.0 mu M N-4-T-8-N was necessary to achieve the same degree of inhibition. N-4-T-8-N is the most potent polyamine inverse agonist presently known and should be a useful tool to elucidate the physiological significance of the polyamine regulatory site of the NMDA receptor complex.

  • Kinetic resolution of primary 2-methyl-substituted alcohols via Pseudomonas cepacia lipase-catalysed enantioselective acylation
    作者:Ove Nordin、Ba-Vu Nguyen、Carin Vörde、Erik Hedenström、Hans-Erik Högberg
    DOI:10.1039/a908023f

    The enantioselectivities of lipases from Pseudomonas cepacia (PFL, Amano PS, etc.) towards a series of primary 2-methyl-substituted alcohols using vinyl acetate as the acyl donor in transesterifications in organic solvents were studied. In terms of enantioselectivity, the best results were found for 3-aryl-2-methylpropan-1-ols with enantiomeric ratios (E-values) over 100 in most cases, whereas other 3-substituted primary 2-methylpropan-1-ols generally displayed lower enantioselectivities: 3-cycloalkyl-2-methylpropan-1-ols (E ≈ 20) and 2-methylalkan-1-ols (E ≈ 10). Moving the aryl group closer or further away from the chiral centre resulted in low enantioselectivities: 2-arylpropan-1-ols (E < 10), 2-methyl-4-(2-thienyl)butan-1-ol (E = 12), 2-methyl-5-(2-thienyl)pentan-1-ol (E = 3.2) and 2-methyl-6-(2-thienyl)hexan-1-ol (E = 3.8).

It was found that Crabtree catalyst (an Ir catalyst) converted efficiently and selectively the thiophene system 2 into 2-aryl-substituted compounds 9. The direct C–H arylation of 2 with electron-rich iodoarenes led to
    据报道,采用后期多样化策略可以快速合成基于噻吩的TAK-779类似物1。在合成结束时,由噻吩分六步制备的关键结构单元2直接与芳烃在α位置进行区域选择性芳基化。由于2提供了多个反应性位置,因此测试了各种已建立的催化剂体系。发现Crabtree催化剂(Ir催化剂)有效且选择性地将噻吩系统2转化为2-芳基取代的化合物9。的直接C-H芳基化2富含电子的芳烃的收率很高,而缺乏电子的芳烃需要更长的反应时间才能完全转化。通过解9和随后的HATU伯胺4的合成来合成一小组多样化的酰胺1。
