Anthracene-Bodipy dyads as fluorescent sensors for biocatalytic diels alder reactions

Fluorescence spectroscopy is a powerful, extremely sensitive technique for the investigation of enzyme and ribozyme mechanisms. Herein, we describe the synthesis and characterization of water-soluble fluorescence probes for studying biocatalytic Diels-Alder reactions. These probes consist of anthracene and sulfonated BODIPY fluorophores fused by conjugated phenylacetylenyl bridges. Intact anthracene efficiently quenches BODIPY fluorescence, likely by photoinduced electron transfer. Upon destruction of the aromatic system by the Diels-Alder reaction, the fluorescence emission increases 20-fold. Binding in the catalytic pocket of a Diels-Alderase ribozyme yields a further ?2-fold increase in the fluorescence intensity of both the anthracene-BODIPY and the Diels-Alder-product-BODIPY probes. Therefore, a fluorescence-based distinction of free substrate, bound substrate, bound product, and free product is possible. With these all-in-one reporters, we monitored RNA-catalyzed Diels-Alder reactions under both single- and multiple-turnover conditions down to the nanomolar concentration range. Burst analysis at the single-molecule level revealed blinking of the dyads between an on state and an off state, presumably due to rotation around the phenylacetylenyl bridge. Binding to the ribozyme does not increase the intensity of the individual fluorescence bursts, but rather increases the average time spent in the on state. Variations in the quantum yields of the different probes correlate well with the degree of conjugation between anthracene and the phenylacetylenyl bridge.

Sterically demanding, zwitterionic trialkylphosphonium sulfonates as air-stable ligand precursors for efficient palladium-catalyzed cross-couplings of aryl bromides and chlorides

3-(Di-tert-butylphosphonium)propane sulfonate (DTB-PPS) and 3-(diadamantylphosphonium)propane sulfonate (DAPPS) are air-stable pre-ligands for aqueous-phase palladium-catalyzed cross-coupling reactions. Both DTBPPS and DAPPS were found to give active catalysts for the Sonogashira coupling of aryl bromides at room temperature and 4-chloroanisole at 80 C. These ligands also gave effective catalysts for the aqueous-phase Suzuki coupling of aryl bromides at room temperature.

Discovery of a Potent and Selective Oral Inhibitor of ERK1/2 (AZD0364) That Is Efficacious in Both Monotherapy and Combination Therapy in Models of Nonsmall Cell Lung Cancer (NSCLC)

The RAS/MAPK pathway is a major driver of oncogenesis and is dysregulated in approximately 30% of human cancers, primarily by mutations in the BRAF or RAS genes. The extracellular-signal-regulated kinases (ERK1 and ERK2) serve as central nodes within this pathway. The feasibility of targeting the RAS/MAPK pathway has been demonstrated by the clinical responses observed through the use of BRAF and MEK inhibitors in BRAF V600E/K metastatic melanoma; however, resistance frequently develops. Importantly, ERK1/2 inhibition may have clinical utility in overcoming acquired resistance to RAF and MEK inhibitors, where RAS/MAPK pathway reactivation has occurred, such as relapsed BRAF V600E/K melanoma. We describe our structure-based design approach leading to the discovery of AZD0364, a potent and selective inhibitor of ERK1 and ERK2. AZD0364 exhibits high cellular potency (IC50 = 6 nM) as well as excellent physicochemical and absorption, distribution, metabolism, and excretion (ADME) properties and has demonstrated encouraging antitumor activity in preclinical models.
