  摘要：

  红椒的甲醇提取物显示出强效的乙酰辅酶A羧化酶抑制活性。通过仪器分析分离并确认了活性成分为（E, E）-和（E, Z）-9-氧代十八烯-10,12-二酸。该化合物的IC50值分别为1.4×10^-6 M和1.5×10^-6 M，其活性几乎是常见脂肪酸的六十倍。对相关化合物的结构-活性关系进行的比较研究表明，抑制活性既不受烷基链中氧官能团的位置和种类的影响，也不受双键的构型影响。然而，发现末端羧基和中链氧官能团之间存在双键会降低抑制活性，而通过氢化双键可以恢复这种活性。

  The development of "molecular rulers" would allow one to quantitatively locate the penetration depth of intercalants within lipid bilayers. To this end, an attempt was made to correlate the C-13 NMR chemical shift of polarizable "reporter" carbons (e.g., carbonyls) of intercalants within DMPC liposomal bilayers - with the polarity it experiences, and with its Angstrom distance from the interface.This requires families of molecules with two "reporter carbons" separated by a known distance, residing at various depths/polarities within the bilayer. For this purpose, two homologous series of dicarbonyl compounds, methyl n-oxooctadecanoates and the corresponding n-oxooctadecanoic acids (n = 4-16), were synthesized. To assist in assignment and detection several homologs in each system were prepared (13)C(-)enriched in both carbonyls. Within each family, the number of carbons and functional groups remains the same, with the only difference being the location of the second ketone carbonyl along the fatty acid chain. Surprisingly, the head groups within each family are not anchored near the lipid-water interface, nor are they even all located at the same depth. Nevertheless, using an iterative best fit analysis of the data points enables one to obtain an exponential curve. The latter gives substantial insight into the correlation between polarity (measured in terms of the Reichardt polarity parameter, E-T(30)) and penetration depth into the liposomal bilayer. Still missing from this curve are data points in the moderate polarity range. (C) 2014 Elsevier Ireland Ltd. All rights reserved.
