Identification and Characterization of a Selective Human Carbonyl Reductase 1 Substrate

During drug discovery efforts targeting inhibition of cytochrome P450 11B2 (CYP11B2)-mediated production of aldosterone as a therapeutic approach for the treatment of chronic kidney disease and hypertension, (S)-6-(5-fluoro-4-(1-hydroxyethyl)pyridin-3-yl)3,4-dihydro-1,8-naphthyridine-1(2H)-carboxamide (1) was identified as a potent and selective inhibitor of CYP11B2. Preclinical studies characterized 1 as low clearance in both in vitro test systems and in vivo in preclinical species. Despite low metabolic conversion, an active ketone metabolite (2) was identified from in vitro metabolite-identification studies. Due to the inhibitory activity of 2 against CYP11B2 as well as the potential for it to undergo reductive metabolism back to 1, the formation and elimination of 2 were characterized and are the focus of this manuscript. A series of in vitro investigations determined that 1 was slowly oxidized to 2 by cytochrome P450s 2D6, 3A4, and 3A5, followed by stereoselective reduction back to 1 and not its enantiomer (3). Importantly, reduction of 2 was mediated by an NADPH-dependent cytosolic enzyme. Studies with human cytosolic fractions from multiple tissues, selective inhibitors, and recombinantly expressed enzymes indicated that carbonyl reductase 1 (CBR1) is responsible for this transformation in humans. Carbonyl reduction is emerging as an important pathway for endogenous and xenobiotic metabolism. With a lack of selective substrates and inhibitors to enable characterization of the involvement of CBR1, 2 could be a useful probe to assess CBR1 activity in vitro in both subcellular fractions and in cell-based systems.

Small-Molecule Screens: A Gateway to Cancer Therapeutic Agents with Case Studies of Food and Drug Administration-Approved Drugs

High-throughput screening (HTS) of small-molecule libraries accelerates the discovery of chemical leads to serve as starting points for probe or therapeutic development. With this approach, thousands of unique small molecules, representing a diverse chemical space, can be rapidly evaluated by biologically and physiologically relevant assays. The origins of numerous United States Food and Drug Administration-approved cancer drugs are linked to HTS, which emphasizes the value in this methodology. The National Institutes of Health Molecular Libraries Program made HTS accessible to the public sector, enabling the development of chemical probes and drug-repurposing initiatives. In this work, the impact of HTS in the field of oncology is considered among both private and public sectors. Examples are given for the discovery and development of approved cancer drugs. The importance of target validation is discussed, and common assay approaches for screening are reviewed. A rigorous examination of the PubChem database demonstrates that public screening centers are contributing to early-stage drug discovery in oncology by focusing on new targets and developing chemical probes. Several case studies highlight the value of different screening strategies and the potential for drug repurposing.

How to Translate the [LCu2(H)](+)-Catalysed Selective Decomposition of Formic Acid into H-2 and CO2 from the Gas Phase into a Zeolite.

Translating a homogenous catalyst into a heterogeneous catalyst requires a fundamental understanding of how the catalyst fits into the zeolite and how the reaction is influenced. Previous studies of bimetallic catalyst design identified a potent copper homobinuclear catalyst, [(L)Cu-2(H)](+) for the selective decomposition of formic acid. Here, a close interplay between theory and experiment shows how to preserve this selective reactivity within zeolites. Gas-phase experiments and DFT calculations showed that switching from 1,1-bis(diphenylphosphino)-methane ligand to the 1,8-naphthyridine ligand produced an equally potent catalyst. DFT calculations show that this new catalyst neatly fits into a zeolite which does not perturb reactivity, thus providing a unique example on how heterogenization of a homogenous catalyst for the selective catalysed extrusion of carbon dioxide from formic acid can be achieved, with important application in hydrogen storage and insitu generation of H-2.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 136-95-8 is helpful to your research. COA of Formula: C7H6N2S.

Novel Supramolecular Block Copolymer of Isotactic Polypropylene and Ethylene-co-propylene Connected by Complementary Quadruple Hydrogen Bonding System

Supramolecular block copolymers comprising isotactic polypropylene (iPP) and ethylene-propylene random copolymers (EP) with complementary quadruple hydrogen bonding junctions have been prepared by melt-mixing of iPP having a 2-ureido-4[1H]-pyrimidinone (UPy) group (iPP-UPy) and elastic EP bearing a 2,7-diamido-1,8-naphthyridine (Napy) group (EP-Napy). Transmission electron Microscope (TEM) analysis of the iPP-UPy/EP-Napy composite showed that the elastic EP domains were well dispersed in the iPP matrix compared, with the traditional iPP/EP impact polypropylene copolymer (IPC). The iPP-UPy/EP-Napy hydrogen-bonded pseudo block copolymer effectively acts as a compatibilizer in the IPC and contribtftes to improved mechanical properties of the resulting iPP/EP composite. There is good correlation between impact strength of the IPC and EP domain size observed by the TEM analysis. The use of the complementary quadruple hydrogen bonding system for blending two immiscible polymers has been shown to result in smaller domain sizes of the EP-phase in the iPP and consequently improved mechanical properties of the supramolecular iPP/EP blends.

Fluorescence Properties and Exciplex Formation of Emissive Naphthyridine Derivatives: Application as Sensors for Amines

Water-soluble donor-acceptor-type fluorophore 15Nap-Cl having two trifluoromethyl groups and a Cl group on a 1,5-aminonaphthyridine framework was prepared. Fluorophore 15Nap-Cl showed strong solvatochromic fluorescence, and, as the solvent polarity increased, a bathochromic shift was observed accompanied by an increase in the fluorescence quantum yield. In addition, in the presence of amines such as ethylamine, diethylamine, and aniline, further considerable bathochromic shifts in the fluorescence were observed. Density functional calculations identified the source of the fluorescence behavior as exciplex formation between 15-Nap-Cl and the corresponding amine. The fluorescence behavior was exploited to fabricate a sensor that can identify various primary, secondary, and tertiary amines.

Luminescence-based colorimetric discrimination of single-nucleotide transversions by the combined use of the derivatives of DOTA-conjugated naphthyridine and its terbium complex

We newly synthesized a nucleobase-binding ligand, ND-DOTA, in which 2-amino-5,7-dimethyl-1,8-naphthyridine (ND) was conjugated with 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid (DOTA) via an amide linker, and found that its terbium(III) complex (ND-DOTA-Tb) showed green emission based on an energy transfer from the naphthyridine moiety to Tb3+. The blue emission of ND-DOTA was selectively quenched by adding abasic site-containing DNA duplexes that have pyrimidine bases opposite to the abasic site. In contrast, at the same excitation wavelength, ND-DOTA-Tb showed green emission independently of the bases opposite to the abasic site. Thus, a mixed solution of ND-DOTA and ND-DOTA-Tb enabled the luminescence-based colorimetric discrimination of single-nucleotide transversions with the naked eye at a single excitation wavelength.
