  energies, as indicated by variations in melting point temperatures. All fluorinated derivatives were found to be somewhat more readily oxidized in human liver microsomes, the rates of degradation correlating with increasing lipophilicity. Because the piperidine‐2‐carboxamide core is chiral, pairs with enantiomeric N‐alkyl groups are diastereomeric. While little response to such stereoisomerism was observed

  通过选择性地将1-3个氟原子引入n-丙基和n中，研究了N-烷基-哌啶-2-羧酰胺的药理相关特性的调节局部麻醉药罗哌卡因和左旋布比卡因的叔丁基侧链。附近氟取代基对碱的调节本质上是加和的，并且表现出随氟与碱中心之间的拓扑距离而变的指数衰减。中性哌啶衍生物的固有亲脂性显示出对连接至中性杂芳基系统的部分氟化烷基的特征响应。但是，附近的氟取代基引起的碱度降低会影响中性pH值的亲脂性，因此所有部分氟化的衍生物的亲脂性都比其未氟化的母体相似或更高。发现水溶性与亲脂性成反比，并且与晶体堆积能有很大关系，如熔点温度的变化所示。发现所有氟化衍生物在人肝微粒体中都更容易被氧化，降解速率与亲脂性增加相关。因为哌啶-2-羧酰胺核心是手性的，所以与对映异构体配对N-烷基是非对映异构的。虽然对于碱性或亲脂性几乎观察不到对这种立体异构的反应，但是对于熔点温度和氧化降解观察到更明显的变化。

The obtained results suggest the same kinetic mechanism of solvolysis of arenesulfonyl chlorides for propan‐1‐ol and propan‐2‐ol, as in MeOH and EtOH, where bimolecular nucleophilic substitution (SN2) takes place with nucleophilic solvent assistance of one alcohol molecule and the participation of the solvent network involving solvent molecules

  我们研究了在303-323 K时丙-1-醇和丙-2-醇对芳烃磺酰氯的溶剂分解机理。动力学曲线适合一阶动力学。反应性随供电子取代基的增加而增加。芳烃磺酰氯的邻烷基取代衍生物显示出增加的反应性，但这种“正向”邻效应的起源仍不清楚。可能，邻位甲基限制了绕C键的旋转，从而促进了亲核试剂的攻击。就亲核性空间效应而言，未发现丙-1-醇和丙-2-醇的相关反应性变化。所有底物的等动力学关系的存在表明该系列的单一机制。两种醇中所有底物的溶剂分解反应均显示等速温度（T iso）接近工作温度范围，这表明该过程受到次级反应性因素的影响，该因素可能是TS中的空间性质。溶剂化在该反应中起重要作用，调节反应性。在一些情况下，存在吨-Bu代替我在对位位置导致第一溶剂化壳的变化，从而增加了反应能量（约1 kJ·mol -1）。所得结果表明，芳烃磺酰氯对丙-1-醇和丙-2-醇的溶剂化动力学机制与在MeOH和EtOH中相同，其中双分子亲核取代（S
• Inscribing the Perimeter of the PagP Hydrocarbon Ruler by Site-Specific Chemical Alkylation

  The Escherichia coli outer membrane phospholipid:lipid A palmitoyltransferase PagP selects palmitate chains using its beta-barrel-interior hydrocarbon ruler and interrogates phospholipid donors by gating them laterally through an aperture known as the crenel. Lipid A palmitoylation provides antimicrobial peptide resistance and modulates inflammation signaled through the host TLR4/MD2 pathway. Gly88 substitutions can raise the PagP hydrocarbon ruler floor to correspondingly shorten the selected acyl chain. To explore the limits of hydrocarbon ruler acyl chain selectivity, we have modified the single Gly88Cys sulfhydryl group with linear alkyl units and identified C10 as the shortest acyl chain to be efficiently utilized. Gly88Cys-S-ethyl, S-n-propyl, and S-n-butyl PagP were all highly specific for C12, C11, and C10 acyl chains, respectively, and longer aliphatic or aminoalkyl substitutions could not extend acyl chain selectivity any further. The donor chain length limit of C10 coincides with the phosphatidylcholine transition from displaying bilayer to micellar properties in water, but the detergent inhibitor lauryldimethylamine At-oxide also gradually became ineffective in a micellar assay as the selected acyl chains were shortened to C10. The Gly88Cys-S-ethyl and norleucine substitutions exhibited superior C12 acyl chain specificity compared to that of Gly88Met PagP, thus revealing detection by the hydrocarbon ruler of the Met side chain tolerance for terminal methyl group gauche conformers. Although norleucine substitution was benign, selenomethionine substitution at Met72 was highly destabilizing to PagP. Within the hydrophobic and van der Waals-contacted environment of the PagP hydrocarbon ruler, side chain flexibility, combined with localized thioether-aromatic dispersion attraction, likely influences the specificity of acyl chain selection.
