Structure–activity relationships of bioisosteres of a carboxylic acid in a novel class of bacterial translation inhibitors
摘要:
The discovery and initial optimization of a novel anthranilic acid derived class of antibacterial agents which suffered from extensive protein binding has been previously reported. The structure-activity relationships around the carboxylic acid substituent are described herein. This acid was replaced by several alternative functional groups in attempts to retain bioactivity while reducing protein binding. Only groups with an acidic proton retained activity, and analogs containing those groups maintained the protein binding inherent to this class of antibacterial agents. (C) 2007 Elsevier Ltd.

Oxidant- and metal-free synthesis of 4(3H)-quinazolinones from 2-amino-N-methoxybenzamides and aldehydes via acid-promoted cyclocondensation and elimination
biologically important 4(3H)-quinazolinones were readily synthesized in good to excellent yields from 2-amino-N-methoxybenzamides and aldehydes via a cascade reaction consisting of AcOH-promoted cyclocondensation and elimination. The current method sets itself apart from the conventional approach utilizing anthranilamide derivatives and aldehydes as building blocks, by its unique features, other than the
