echo is used to study the spatial distribution of spin-labeled [TOAC-4]-trichogin GA IV analog bound to the cell membrane of the Gram-positive bacteriumMicrococcus luteus. The intermolecular dipole-dipole spin-spin interaction of TOAC spin labels has been experimentally studied at 77 K in glassy dispersions of the spherical cell particles. It is shown that the nonaggregated peptide molecules are distributed
Trichogin GA IV 是一种最短的真菌来源的无环线性多肽抗生素,其特征是在 C 端存在三个 α-氨基异丁酸残基、一个 N-辛酰基和一个氨基醇。它的抗生素活性通常被认为是基于其自组装和膜修饰特性。电子自旋回波中的双电子-电子共振技术用于研究与革兰氏阳性菌藤黄微球菌的细胞膜结合的自旋标记的 [TOAC-4]-trichogin GA IV 类似物的空间分布。TOAC 自旋标记的分子间偶极-偶极自旋-自旋相互作用已在 77 K 下在球形细胞颗粒的玻璃状分散体中进行了实验研究。结果表明,未聚集的肽分子分布在细胞质膜上。

The action of 3-chloroperbenzoic acid on eleven aralkylamines yielded the C-nitrosodimers; physical properties of the compounds, including UV, IR, NMR and MS data are reported. The stability of the nitroso dimers was investigated. The 2-nitroso-1-phenylpropane dimer was converted into its hydrazo-, azo- and azoxy-derivatives.
desaturation of amines. These hybrid Pd-radical intermediates are efficiently generated under mild photoinduced conditions and are capable of a 1,n-HAT (n = 5-7) event at C(sp3)-H sites. The selectivity of HAT is tunable by varying different auxiliaries, which highlight the generality of this method. Remarkably, this desaturation method, which operates under mild conditions and does not require employment
Homogeneous hydrogenation of nitroaliphatic compounds catalyzed by group VIII transition metal phosphine complexes

A variety of GroupVIII transition metal phosphine complexes were shown to be active catalysts for hydrogenation of nitroaliphatic compounds. The catalysis was determined to be homogeneous based on results of selective catalyst poisoning experiments using dibenzo[a,e]cyclooctatetraene and Hg. A deuterium labeling study showed that in the absence of added base the primary hydrogenation pathway does
