Synthesis of Quinazolin-4(3H)-ones via a novel approach
The present work was designed based on the new multi-component reaction, which forms 2-aryl/alkyl-quinazolin-4(3H)-ones in a one-pot reaction with good to excellent yields (86–97 %) using 2-aminobenzoic acid, organic acid, and ammonium ...

4-nitrobenzoate inhibits 4-hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy. [PDF]
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...
