Symmetric bis-chalcones as a new type of breast cancer resistance protein inhibitors with a mechanism different from that of chromones

Potent ABCG2 inhibitors were recently identified as asymmetric chromones with different types of substituents. We here synthesized symmetric bis-chalcones that were differently substituted and screened for their ability to inhibit mitoxantrone efflux from ABCG2-transfected HEK293 cells. Potent bis-chalcone inhibitors were identified, the efficiency depending on both position of the central ketone groups and the number and positions of lateral methoxy substituents the best derivative, namely, 1p, was selective for ABCG2 over P-glycoprotein and MRP1, appeared not to be transported by ABCG2, and was at least as active on various drug-selected cancer cells overexpressing ABCG2. Compound 1p stimulated the ABCG2 basal ATPase activity by contrast to a chromone lead that inhibited it, suggesting different mechanisms of interaction. Combination of both types of inhibitors produced synergistic effects, leading to complete inhibition at very low concentrations.

Meta C-H Arylation of Electron-Rich Arenes: Reversing the Conventional Site Selectivity

Controlling site selectivity of C-H activation without using a directing group remains a significant challenge. While Pd(II) catalysts modulated by a mutually repulsive pyridine-type ligand have been shown to favor the relatively electron-rich carbon centers of arenes, reversing the selectivity to favor palladation at the relatively electron-deficient positions has not been possible. Herein we report the first catalytic system that effectively performs meta C-H arylation of a variety of alkoxy aromatics including 2,3-dihydrobenzofuran and chromane with exclusive meta site selectivity, thus reversing the conventional site selectivity governed by native electronic effects. The identification of an effective ligand and modified norbornene (NBE-CO2Me), as well as taking advantage of the statistics, are essential for achieving the exclusive meta selectivity.

Discovery of Indole Derivatives as Novel and Potent Dengue Virus Inhibitors

3-Acyl-indole derivative 1 was identified as a novel dengue virus (DENV) inhibitor from a DENV serotype 2 (DENV-2) phenotypic antiviral screen. Extensive SAR studies led to the discovery of new derivatives with improved DENV-2 potency as well as activity in nanomolar to micromolar range against the other DENV serotypes. In addition to the potency, physicochemical properties and metabolic stability in rat and human microsomes were improved during the optimization process. Chiral separation of the racemic mixtures showed a clear preference for one of the two enantiomers. Furthermore, rat pharmacokinetics of two compounds will be discussed in more detail, demonstrating the potential of this new series of pan-serotype-DENV inhibitors.

Structure?activity relationship study of DEL-22379: ERK dimerization inhibitors with increased safety

Abstract: Aberrant activation of ERK signaling pathway usually leads to oncogenesis, and small molecular agents targeting this pathway are impeded by the emergence of drug resistance due to reactivation of ERK signaling. Compound DEL-22379 has been reported to inhibit ERK dimerization which was unaffected by drug-resistant mechanism reactivating the ERK signaling. Here, we discussed a structure?activity relationship study of DEL-22379. Forty-seven analogues were designed and synthesized. Each synthesized compound was biologically evaluated for their inhibitory rates on several tumor cell lines and compounds with high inhibitory rates were further evaluated for IC50 values. The structure?activity relationship of idolin-2-one scaffold and the impact of Z/E configuration on potency were discussed. Potential safety of two synthesized analogues was investigated and in silico docking study of five compounds was performed to understand the structural basis of ERK dimerization inhibition.

Direct and Regioselective C-H Oxidative Difluoromethylation of Heteroarenes

The difluoromethyl group (CF2H) is of great interest in the area of medicinal chemistry. However, the investigation of molecular scaffolds containing this group has been hampered by the limitation of synthetic methods for the introduction of CF2H into heteroarenes. Herein we disclose a new strategy for the direct introduction of a difluoromethyl group into heteroarenes via the copper-mediated C-H oxidative difluoromethylation of heteroarenes with TMSCF2H. This mild and regioselective method enables the convenient synthesis of a range of difluoromethylated heteroarenes in high yields. The usage of 9,10-phenanthrenequinone (PQ) as an oxidant is critical to the success of this new difluoromethylation reaction.
