Pardon, Els; Betti, Cecilia; Laeremans, Toon; Chevillard, Florent; Guillemyn, Karel; Kolb, Peter; Ballet, Steven; Steyaert, Jan published the artcile< Nanobody-Enabled Reverse Pharmacology on G-Protein-Coupled Receptors>, Recommanded Product: 4-(Thiazol-2-yl)benzaldehyde, the main research area is nanobody beta2 adrenoreceptor fusion G protein coupled receptor agonist; GPCRs; drug discovery; fragment screening; inhibitors; nanobodies.

The conformational complexity of transmembrane signaling of G-protein-coupled receptors (GPCRs) is a central hurdle for the design of screens for receptor agonists. In their basal states, GPCRs have lower affinities for agonists compared to their G-protein-bound active state conformations. Moreover, different agonists can stabilize distinct active receptor conformations and do not uniformly activate all cellular signaling pathways linked to a given receptor (agonist bias). Comparative fragment screens were performed on a β2-adrenoreceptor-nanobody fusion locked in its active-state conformation by a G-protein-mimicking nanobody, and the same receptor in its basal-state conformation. This simple biophys. assay allowed the identification and ranking of multiple novel agonists and permitted classification of the efficacy of each hit in agonist, antagonist, or inverse agonist categories, thereby opening doors to nanobody-enabled reverse pharmacol.

Vilaboa, Nuria’s team published research in Nucleic Acids Research in 2017-05-15 | 324579-90-0

Vilaboa, Nuria; Bore, Alba; Martin-Saavedra, Francisco; Bayford, Melanie; Winfield, Natalie; Firth-Clark, Stuart; Kirton, Stewart B.; Voellmy, Richard published the artcile< New inhibitor targeting human transcription factor HSF1: effects on the heat shock response and tumor cell survival>, Category: thiazole, the main research area is human transcription factor HSF1 inhibitor preparation heat shock antitumor.

Comparative modeling of the DNA-binding domain of human HSF1 facilitated the prediction of possible binding pockets for small mols. and definition of corresponding pharmacophores. In silico screening of a large library of lead-like compounds identified a set of compounds that satisfied the pharmacophoric criteria, a selection of which compounds was purchased to populate a biased sublibrary. A discriminating cell-based screening assay identified compound 001, which was subjected to systematic anal. of structure-activity relationships, resulting in the development of compound 115 (IHSF115). IHSF115 bound to an isolated HSF1 DNA binding domain fragment. The compound did not affect heat-induced oligomerization, nuclear localization and specific DNA binding but inhibited the transcriptional activity of human HSF1, interfering with the assembly of ATF1-containing transcription complexes. IHSF115 was employed to probe the human heat shock response at the transcriptome level. In contrast to earlier studies of differential regulation in HSF1-naive and -depleted cells, the authors’ results suggest that a large majority of heat-induced genes is pos. regulated by HSF1. That IHSF115 effectively countermanded repression in a significant fraction of heat-repressed genes suggests that repression of these genes is mediated by transcriptionally active HSF1. IHSF115 is cytotoxic for a variety of human cancer cell lines, multiple myeloma lines consistently exhibiting high sensitivity.

A review. In vivo bioluminescence imaging (BLI), which is based on luminescence emitted by the luciferase-luciferin reaction, has enabled continuous monitoring of various biochem. processes in living animals. Bright luminescence with a high signal-to-background ratio, ideally red or near-IR light as the emission maximum, is necessary for in vivo animal experiments Various attempts have been undertaken to achieve this goal, including genetic engineering of luciferase, chem. modulation of luciferin, and utilization of bioluminescence resonance energy transfer (BRET). In this review, we overview a recent advance in the development of a bioluminescence system for in vivo BLI. We also specifically examine the improvement in bioluminescence intensity by mutagenic or chem. modulation on several beetle and marine luciferase bioluminescence systems. We further describe that intramol. BRET enhances luminescence emission, with recent attempts for the development of red-shifted bioluminescence system, showing great potency in in vivo BLI. Perspectives for future improvement of bioluminescence systems are discussed.

Journal of Medicinal Chemistrypublished new progress about Antiviral agent resistance. 1003-32-3 belongs to class thiazole, and the molecular formula is C4H3NOS, Electric Literature of 1003-32-3.

Zhao, Xin; Li, Runfeng; Zhou, Yang; Xiao, Mengjie; Ma, Chunlong; Yang, Zhongjin; Zeng, Shaogao; Du, Qiuling; Yang, Chunguang; Jiang, Haiming; Hu, Yanmei; Wang, Kefeng; Mok, Chris Ka Pun; Sun, Ping; Dong, Jianghong; Cui, Wei; Wang, Jun; Tu, Yaoquan; Yang, Zifeng; Hu, Wenhui published the artcile< Discovery of Highly Potent Pinanamine-Based Inhibitors against Amantadine- and Oseltamivir-Resistant Influenza A Viruses>, Electric Literature of 1003-32-3, the main research area is preparation antiviral pinanamine derivative resistant influenza A virus.

Influenza pandemic is a constant major threat to public health caused by influenza A viruses (IAVs). IAVs are subcategorized by the surface proteins hemagglutinin (HA) and neuraminidase (NA), in which they are both essential targets for drug discovery. While it is of great concern that NA inhibitor oseltamivir resistant strains are frequently identified from human or avian influenza virus, structural and functional characterization of influenza HA has raised hopes for new antiviral therapies. In this study, we explored a structure-activity relationship (SAR) of pinanamine-based antivirals and discovered a potent inhibitor M090 against amantadine-resistant viruses, including the 2009 H1N1 pandemic strains, and oseltamivir-resistant viruses. Mechanism of action studies, particularly hemolysis inhibition, indicated that M090 targets influenza HA and it occupied a highly conserved pocket of the HA2 domain and inhibited virus-mediated membrane fusion by “”locking”” the bending state of HA2 during the conformational rearrangement process. This work provides new binding sites within the HA protein and indicates that this pocket may be a promising target for broad-spectrum anti-influenza A drug design and development.

Modulators of sirtuins are considered promising therapeutic targets for the treatment of cancer, cardiovascular, metabolic, inflammatory, and neurodegenerative diseases. Here we prepared new 1,4-dihydropyridines (DHPs) bearing changes at the C2/C6, C3/C5, C4, or N1 position. Tested with the SIRTainty procedure, some of them displayed increased SIRT1 activation with respect to the prototype 3a, high NO release in HaCat cells, and ameliorated skin repair in a mouse model of wound healing. In C2C12 myoblasts, two of them improved mitochondrial d. and functions. All the effects were reverted by coadministration of compound C (9), an AMPK inhibitor, or of EX-527 (10), a SIRT1 inhibitor, highlighting the involvement of the SIRT1/AMPK pathway in the action of DHPs. Finally, tested in a panel of cancer cells, the water-soluble form of 3a, compound 8, displayed antiproliferative effects in the range of 8-35 μM and increased H4K16 deacetylation, suggesting a possible role for SIRT1 activators in cancer therapy.

Liu, Gui-Chun; Dong, Zhi-Wei; Hou, Qing-Bai; He, Jin-Wu; Zhao, Ruo-Ping; Wang, Wen; Li, Xue-Yan published the artcile< Second Rhagophthalmid Luciferase Cloned from Chinese Glow-worm Menghuoius giganteus (Rhagophthalmidae: Elateroidea)>, Quality Control of 2591-17-5, the main research area is sequence luciferase mol cloning Rhagophthalmus Menghuoius.

The pH-insensitive beetle luciferases cloned from Rhagophthalmidae, Phengodidae, and Elateridae exhibit great potential application as reporter assays for monitoring gene expression. At present, however, only one luciferase has been reported from the enigmatic and predominantly Asian distributed luminous family Rhagophthalmidae. Here, we cloned the second rhagophthalmid luciferase from the Chinese glow-worm Menghuoius giganteus (Rhagophthalmidae: Elateroidea) by combining reverse transcription polymerase chain reaction (RT-PCR) with rapid amplification of complementary DNA ends (RACE). The luciferase consisted of 546 amino acids and showed high identity to that of Rhagophthalmus ohbai (90.4%). The recombinant M. giganteus luciferase was produced in vitro and exhibited significant bioluminescent activity under neutral conditions (pH 7.8), with low KM for D-luciferin (2.2μM) and ATP (53μM). Activity was highest at 10°C and inactivation occurred at 45°C. This luciferase showed pH-insensitivity and maximum emission spectrum at 560 nm. Phylogenetic analyses based on the deduced amino acids indicated a close relationship between the M. giganteus luciferase and that of R. ohbai. These results increase our understanding of rhagophthalmid luciferases and provide a new resource for the application of luciferases.
