Identification of an Activity Selector for the Nitroso‐Forming Activity in Bacterial Type‐III Copper Enzymes

Angewandte Chemie International Edition, Accepted Article.
O‐aminophenol oxidases, a specialized subclass of type‐III copper proteins, play a crucial role in the biosynthesis of bioactive nitrosophenols which display antiretroviral and blood cholesterol lowering activity. Another related subclass of type‐III copper proteins, tyrosinases, closely resemble o‐aminophenol oxidases both structurally and ...

Maxwell and Kerr effects in solutions of macromolecules with dendrons in side groups [PDF]

arXiv, 2009
Linear polymers with dendrons of first and second generations based on L-aspargic acid are studied by the methods of flow birefringence and electric birefringence. Optical, dipole, dynamic, and conformational properties of the macromolecules, as well as contributions to their optical anisotropy due to macroform and microform effects, are investigated ...

Advances in Metal‐Free Transamidation: A Sustainable Approach to Amide Bond Formation

Chemistry – An Asian Journal, EarlyView.
This review highlights the recent developments of transamidation reactions under metal‐free reaction conditions. Various amines including weak nucleophilic amines such as aromatic amines have been used to achieve the transamidation reactions under mild and relatively green reaction conditions. Abstract The amide functionalities are a crucial functional

Radiosynthesis and evaluation of a 68Ga‐labeled brominated benzamide derivative for detection of melanoma in small animals

Bulletin of the Korean Chemical Society, EarlyView.
Malignant melanoma has the highest mortality rate among skin cancers due to its aggressiveness and metastatic potential, and early diagnosis is important because treatment options are limited. We synthesized a brominated benzamide derivative labeled with 68Ga and evaluated its biological properties as a PET imaging probe.
