Novel β-carboline–quinazolinone hybrids are able to inhibit Leishmania donovani TR (LdTR). Molecular docking studies to investigate possible binding sites were performed.
Abstract An efficient, practical approach to the copper-catalyzed synthesis of 2,3-disubstituted quinazolin-4(3H)-one derivatives is described. The preparation involves treatment of benzyl amines with benzyl anthranilamides in the presence of Cu(OAc)2 and tetra-n-butylammonium bromide (TBAB).
