Amine oxidases are useful bio‐catalysts for the synthesis of enantiomerically pure 1°, 2° and 3° chiral amines. Enzymes in this class (e.g., MAO‐N from Aspergillus niger) reported previously have been shown to be highly S selective. Herein we report the development of an enantiocomplementary R‐selective amine oxidase based on 6‐hydroxy‐D‐nicotine oxidase (6‐HDNO) with broadened substrate scope and

The present invention is directed to the antimalarial activity of various 3',4'-dihydro-2'H-spiro[indoline-3:1'-isoquinolin]-2-ones and related compounds. The present invention is also directed to the use of these compounds as antimalarial agents, in the treatment of malaria. In addition, the invention relates to pharmaceutical compositions comprising one or more of these compounds alone or in combination with other therapeutic agents for the treatment and/or radical cure of severe acute malaria. The invention is also directed to the use of these agents alone and in combination with other agents in malaria prophylaxis, for example, by inhibiting and/or reducing the likelihood of a malaria infection.

electrochemical oxidation are disclosed. In the presence of nitric acid, the selective partial dehydrogenation of tetrahydroisoquinolines to form 3,4-dihydroisoquinolines was achieved via anodic oxidation. The results of CV (Cyclic Voltammograms) experiments and DFT calculations showed the 3,4-dihydroisoquinolines protonated by an external Brønsted acid to be less prone than their unprotonated counterparts
