Abstract
ATAD2 is an epigenetic bromodomain-containing target which is overexpressed in many cancers and has been suggested as a potential oncology target. While several small molecule inhibitors have been described in the literature, their cellular activity has proved to be underwhelming. In this work, we describe the identification of a novel series of ATAD2 inhibitors by high throughput screening, confirmation of the bromodomain region as the site of action, and the optimization campaign undertaken to improve the potency, selectivity, and permeability of the initial hit. The result is compound 5 (AZ13824374), a highly potent and selective ATAD2 inhibitor which shows cellular target engagement and antiproliferative activity in a range of breast cancer models.

Abstract
Practical Pd-catalyzed 2-pyridones were designed to achieve chromeno[2,3-b]pyridine-2-ones. The reaction proceeds through domino nucleophilic addition and decarboxylative arylation, respectively. This methodology offers a moderately efficient approach to construct the bioactive, fused-heterocyclic skeletons via selective C-O bond formation and decarboxylative arylation in a single step with high selectivity and good yields.

Abstract
Synthesis of 2,3-disubstituted 4-ethoxycarbonyl-β-carbolin-1-ones is developed using palladium-catalyzed intramolecular amination of 3-amino-4-(2-bromophenyl)-2-pyridones prepared by the conjugate addition reaction of diethyl 2-aminomalonate to alkynyl imines. The method was applied to the total syntheses of SL651498 exhibiting anxiolytic activity and its analogue.
