A Versatile Strategy for the Synthesis of 4,5-Dihydroxy-2,3-Pentanedione (DPD) and Related Compounds as Potential Modulators of Bacterial Quorum Sensing
in both Gram-negative and Gram-positive bacteria. In this study, a practical and versatile synthesis of racemic DPD is presented. Compared to previously reported syntheses, the proposed strategy is short and robust: it requires only one purification step and avoids the use of expensive or hazardous startingmaterials as well as the use of specific equipment. It is therefore well suited to the synthesis

The present invention relates to indole derivatives useful in therapy, to compositions comprising said compounds, and to methods of treating diseases comprising administration of said com- pounds. The compounds referred to are positive allosteric modulators (PAMs) of the nicotinic acetylcholine α7 receptor.
chiral α‐ and β‐branched nitriles is reported. This process is based on a biocatalytic dehydration of racemic aldoximes by using an aldoxime dehydratase and proceeds with high conversion and excellent enantioselectivity (up to 98 % ee) with water as the only side‐product when starting from a racemic substrate with a high E/Z ratio. Thus, in combination with the facile generation of aldoximes through

Glucose flux through glucokinase (GK) controls insulin release from the pancreas in response to high levels of glucose. Flux through GK is also responsible for reducing hepatic glucose output. Since many individuals with type 2 diabetes appear to have an inadequacy or defect in one or both of these processes, identifying compounds that can activate GK could provide a therapeutic benefit. Herein we report the further structure activity studies of a novel series of glucokinase activators (GKA). These studies led to the identification of pyridine 7 2 as a potent GKA that lowered post-prandial glucose in normal C57BL/6J mice, and after 14d dosing in ob/ob mice.
