Detergents are the most frequently applied reagents in membraneprotein (MP) studies. The limited diversity of one-head-one-tailed traditional detergents, however, is far from sufficient for structurally distinct MPs. Expansion of detergent repertoire has a continuous momentum. In line with the speculation that detergent pre-assembly exerts superiority, herein we report for the first time cross-conjugation
去污剂是膜蛋白 (MP) 研究中最常用的试剂。然而,一头一尾传统洗涤剂的有限多样性对于结构不同的 MP 来说还远远不够。洗涤剂品种的扩张势头不断。与去污剂预组装发挥优势的推测一致,本文首次报道了两个系列单体去污剂的交叉共轭,用于构建二聚去污剂的二维库。最佳去污剂在个体 MP 的系统评估中具有独特的偏好。此外,前所未有的混合去污剂 14M8G 和 14M9G 分别实现了转运蛋白 MsbA 的高质量 EM 研究和 G 蛋白偶联受体 A2A AR 的 NMR 研究。鉴于交叉偶联化学物质的丰富性,

Phenolic thioethers of the formula:
wherein R is a hydrogen atom or a protective group for carboxyl, X is a straight or branched C₄-C₁₅ alkylene group, a straight or branched C₁-C₁₅ alkylene group having a phenylene group or a straight or branched C₂-C₁₅ alkenylene group, and their salts, which inhibit the denaturation of low density lipoproteins (LDL) and the incorporation of LDL by macrophages and are useful as anti-arteriosclerosis agents.
Iminyl Radicals from α-Azido <i>o</i>-Iodoanilides via 1,5-H Transfer Reactions of Aryl Radicals: New Transformation of α-Azido Acids to Decarboxylated Nitriles
The radical reaction of tributyltin hydride with o-iodo-N-methylanilides derived from alpha-azido acids provides an excellent access to alpha-(aminocarbonyl)iminyl radicals through 1,5-hydrogen transfer reaction of initially formed aryl radicals followed by beta-elimination of dinitrogen from ensuing alpha-azido-alpha-(aminocarbonyl)alkyl radicals. The outcoming iminyls display a peculiar tendency to form corresponding nitriles by beta-elimination of aminocarbonyl radicals.

The invention comprises methods for decreasing colonization by a bacterium of a gut of a stink bug, the method comprising providing a composition comprising vanillin or an analog thereof; and delivering said composition to an egg from which the stink bug will hatch, whereby colonization by the bacterium within the gut of the stink bug hatched from the egg treated with the composition is decreased relative to a stink bug hatched from an untreated egg. In some embodiments, the decrease in colonization by the bacterium decreases the fitness of the stink bug, e.g., decreases reproductive ability, survival, rate of development, number of eggs, number of hatched eggs, adult emergence rate, body length, body width, body mass, or cuticle thickness. In some embodiments of the methods herein, the bacterial colonization-disrupting agent is an inhibitor of bacterial metabolism. In some embodiments, the bacterial colonization-disrupting agent is a polyhydroxyalkanoate (PHA) synthesis inhibitor.
