A small-molecule inhibitor with a 1,4-dibenzoylpiperazine scaffold was designed to match the critical binding elements in the β-catenin/B-cell lymphoma 9 (BCL9) protein-protein interaction interface. Inhibitor optimization led to a potent inhibitor that can disrupt the β-catenin/BCL9 interaction and exhibit 98-fold selectivity over the β-catenin/cadherin interaction. The binding mode of new inhibitors was characterized by structure-activity relationships and site-directed mutagenesis studies. Cell-based studies demonstrated that this series of inhibitors can selectively suppress canonical Wnt signaling and inhibit growth of Wnt/β-catenin-dependent cancer cells.

This article describes a sequential Ir/Cu-mediated process for the meta-selective C-H radiofluorination of (hetero)arene substrates. In the first step, Ir-catalyzed C(sp2)-H borylation affords (hetero)aryl pinacolboronate (BPin) esters. The intermediate organoboronates are then directly subjected to copper-mediated radiofluorination with [18F]tetrabutylammonium fluoride to afford fluorine-18 labeled (hetero)arenes in high radiochemical yield and radiochemical purity. This entire process is performed on a benchtop without Schlenk or glovebox techniques and circumvents the need to isolate (hetero)aryl boronate esters. The reaction was automated on a TracerLab FXFN module with 1,3-dimethoxybenzene and a meta-tyrosine derivative. The products, [18F]1-fluoro-3,5-dimethoxybenzene and an 18F-labeled meta-tyrosine derivative, were obtained in 37 ± 5% isolated radiochemical yield and >99% radiochemical purity and 25% isolated radiochemical yield and 99% radiochemical purity, and 0.52 Ci/μmol (19.24 GBq/μmol) molar activity (Am), respectively.

A Rh(III)-catalyzed twofold unsymmetrical C-H alkenylation-annulation/thiolation reaction has been developed, enabling the straightforward and efficient synthesis of various thiobenzofurans in one step. This robust protocol proceeds with a broad substrate scope and good functional group tolerance under relatively mild reaction conditions.

In the present study, a series of benzamides, endowed with potent dopamine D2, serotonin 5-HT1A and 5-HT2A receptors properties, was synthesized and evaluated as potential antipsychotics. Among them, 3-(4-(4-(6-fluorobenzo[d]isoxazol-3-yl)-piperidin-1-yl)butoxy)-N-methylbenzamide (21) and its fluoro-substituted analogue (22) held the best pharmacological binding profiles. They not only presented potent activities for D2, 5-HT1A, and 5-HT2A receptors, but were also endowed with low activities for 5-HT2C, H1 receptors and hERG channels, suggesting a low propensity of inducing weight gain and QT prolongation. In animal models, compounds 21 and 22 reduced phencyclidine-induced hyperactivity with a high threshold for catalepsy induction. It thus provides potential candidates for further preclinical studies.
