- From PARP1 to TNKS2 inhibition: A structure-based approach
-
Tankyrases (TNKSs) have recently gained great consideration as potential targets in Wnt/β-catenin pathway-dependent solid tumors. Previously, we reported the 2-mercaptoquinazolin-4-one MC2050 as a micromolar PARP1 inhibitor. Here we show how the resolution of the X-ray structure of PARP1 in complex with MC2050, combined with the computational investigation of the structural differences between TNKSs and PARP1/2 active sites, provided the rationale for a structure-based drug design campaign that with a limited synthetic effort led to the discovery of the bis-quinazolinone 5 as a picomolar and selective TNKS2 inhibitor, endowed with antiproliferative effects in a colorectal cancer cell line (DLD-1) where the Wnt pathway is constitutively activated.

- One-Pot Cascade Synthesis of Quinazolin-4(3H)-ones via Nickel-Catalyzed Dehydrogenative Coupling of o-Aminobenzamides with Alcohols
-
In this paper, we report a general, efficient, and environmentally benign method for the one-pot cascade synthesis of quinazolin-4(3H)-ones via acceptorless dehydrogenative coupling of o-aminobenzamide with alcohols catalyzed by a simple Ni(II) catalyst, [Ni(MeTAA)], featuring a tetraaza macrocyclic ligand (tetramethyltetraaza[14]annulene (MeTAA)). A wide variety of substituted quinazolin-4(3H)-ones were synthesized in high yields starting from readily available benzyl alcohols and o-aminobenzamides. Several controlled reactions along with deuterium labeling studies were carried out to establish the acceptorless dehydrogenative nature of the reactions.
