Discovery of BMS-986202: A Clinical Tyk2 Inhibitor that Binds to Tyk2 JH2

A search for structurally diversified Tyk2 JH2 ligands from 6 (BMS-986165), a pyridazine carboxamide-derived Tyk2 JH2 ligand as a clinical Tyk2 inhibitor currently in late development for the treatment of psoriasis, began with a survey of six-|membered heteroaryl groups in place of the N-methyl triazolyl moiety in 6. The X-ray co-crystal structure of an early lead (12) revealed a potential new binding pocket. Exploration of the new pocket resulted in two frontrunners for a clinical candidate. The potential hydrogen bonding interaction with ThrS99 in the pocket was achieved with a tertiary amide moiety, confirmed by the X-ray co-crystal structure of 29. When the diversity search was extended to nicotinamides, a single fluorine atom addition was found to significantly enhance the permeability, which directly led to the discovery of 7 (BMS-986202) as a clinical Tyk2 inhibitor that binds to Tyk2 JH2. The preclinical studies of 7, including efficacy studies in mouse models of IL-23-driven acanthosis, anti-CD40-induced colitis, and spontaneous lupus, will also be presented.

cis-C=C Bond and Amide Regulated Oriented Supramolecular Assembly on Two-Dimensional Atomic Crystals

The precise control of the molecular position and orientation of its nanoscale assembly on atomic crystals is pivotal for fabricating hybrid organic/inorganic van der Waals heterostructures with targeted function- alities. Recently, we observed the assembly of oleamide into nanoribbons, orienting exclusively along a crystallographic direction on a variety of atomic crystals. Motivated by this observation, we designed a series of long-chain alkanes, alkenes, and their derivatives with -OH, -COOH, and -CONH2 terminal groups to unveil how chemical units regulate the orientation of suparamolecular assembly by density functional theory calculations. We found that the cis-C=C bond can increase the rigidity of long alkyl chains, tailoring angles and van der Waals interactions between them, while the -CONH2 group facilitates intermolecular hydrogen bonds. Either of these two moieties is required for the oriented assembly on both hexagonal and orthorhombic atomic lattices. We predicted that nanoribbons formed by long-chain cis-alkene and derivatives orient along the zigzag direction on graphene and 32 degrees deflected from the armchair direction on black phosphorene, which were supported by the experiment. The fundamental understandings toward the chemical group regulated intermolecular interactions, and their interplay in the oriented supramolecular assembly is expected to substantially expedite the design and controlled synthesis of organic/inorganic van der Waals heterostructures using the bottom-up method.

Effect of an Imposed Contact on Secondary Structure in the Denatured State of Yeast Iso-1-cytochrome c

There is considerable evidence that long-range interactions stabilize residual protein structure under denaturing conditions. However, evaluation of the effect of a specific contact on structure in the denatured state has been difficult. Iso-1-cytochrome c variants with a Lys54 -> His mutation form a particularly stable His-heme loop in the denatured state, suggestive of loop-induced residual structure. We have used multidimensional nuclear magnetic resonance methods to assign H-1 and N-15 backbone amide and C-13 backbone and side chain chemical shifts in the denatured state of iso-1-cytochrome c carrying the Lys54 -> His mutation in 3 and 6 M guanidine hydrochloride and at both pH 6.4, where the His54-heme loop is formed, and pH 3.6, where the His54-heme loop is broken. Using the secondary structure propensity score, with the 6 M guanidine hydrochloride chemical shift data as a random coil reference state for data collected in 3 M guanidine hydrochloride, we found residual helical structure in the denatured state for the 60s helix and the C-terminal helix, but not in the N-terminal helix in the presence or absence of the His54-heme loop. Non-native helical structure is observed in two regions that form Omega-loops in the native state. There is more residual helical structure in the C-terminal helix at pH 6.4 when the loop is formed. Loop formation also appears to stabilize helical structure near His54, consistent with induction of helical structure observed when His heme bonds form in heme-peptide model systems. The results are discussed in the context of the folding mechanism of cytochrome c.

R5 HIV-1 gp120 Activates p38 MAPK to Induce Rat Cardiomyocyte Injury by the CCR5 Coreceptor

Background: Effective antiretroviral therapy extends the survival of patients with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome, but these patients remain at higher risk for heart diseases compared with the general population. Previous studies have suggested that HIV-1 glycoprotein 120 (gp120) may be associated with heart disease. However, the underlying mechanisms by which HIV-1 gp120-mediated myocardial injury occurs remain unknown. Objective: The current study aimed to uncover the mechanism of C-C chemokine receptor 5 (CCR5) coreceptor (R5) HIV-1 gp120-induced myocardial injury. Methods: Morphology analysis, determination of the percentage of cell apoptosis, as well as lactate dehydrogenase (LDH) and creatine kinase (CK) assays were used to analyze whether R5 HIV-1 gp120 induced myocardial cell injury. We analyzed the phosphorylation of p38 mitogen-activated protein kinase (MAPK) with the CCR5 antagonist D-Ala-peptide T-amide (DAPTA) and NMDA receptor antagonist MK801, detected LDH and CK assays with p38 MAPK antagonist SB203580 (SB), and detected the percentage of cell apoptosis and death with DAPTA to investigate the mechanism of R5 HIV-1 gp120-induced myocardial cell injury. Results: R5 HIV-1 gp120 damaged myocardial cells and induced p38 MAPK phosphorylation. SB blocked R5 HIV-1 gp120-induced myocardial cell injury. DAPTA blocked R5 HIV-1 gp120-mediated p38 MAPK phosphorylation, while MK801 did not. DAPTA inhibited R5 HIV-1 gp120-induced myocardial cell injury. Conclusion: Our data indicate that R5 HIV-1 gp120 activated p38 MAPK to trigger myocardial cell injury by the CCR5 coreceptor.

Design, synthesis, anticancer and antioxidant activities of amide linked 1,4-disubstituted 1,2,3-triazoles

To explore anticancer and antioxidant agents with improved potency, we synthesized a series of amide linked 1,4-disubstituted 1,2,3-triazoles through click chemistry approach. The structure of synthesized triazoles were characterized by- FTIR, H-1 NMR, C-13 NMR spectroscopy and HRMS. All the synthesized compounds were screened for their anticancer activity against four different cell lines- PC3 (prostate cancer), A549 (lung cancer), MIAPACA (liver cancer), Fr2 (Breast epithelial), reflecting compounds 7e and 7f to possess good activity. The antioxidant activity was evaluated by using stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay and compound 7d showed promising activity having IC50 value 1.61 mu g/ml. Molecular docking studies of compounds 7e and 7f was carried out in active site of human epidermal growth factor receptor 2 revealed high binding affinities and within toxicity limits. The experimental results were in good agreement with docking studies. In-silico ADME studies of synthesized compounds also have good dispositional profile and are patient compliant, may be potential future candidates for anticancer treatment. (C) 2020 Elsevier B.V.

Amino acid side chain contribution to protein FTIR spectra: impact on secondary structure evaluation

Prediction of protein secondary structure from FTIR spectra usually relies on the absorbance in the amide I-amide II region of the spectrum. It assumes that the absorbance in this spectral region, i.e., roughly 1700-1500 cm(-1) is solely arising from amide contributions. Yet, it is accepted that, on the average, about 20% of the absorbance is due to amino acid side chains. The present paper evaluates the contribution of amino acid side chains in this spectral region and the potential to improve secondary structure prediction after correcting for their contribution. We show that the beta-sheet content prediction is improved upon subtraction of amino acid side chain contributions in the amide I-amide II spectral range. Improvement is relatively important, for instance, the error of prediction of beta-sheet content decreases from 5.42 to 4.97% when evaluated by ascending stepwise regression. Other methods tested such as partial least square regression and support vector machine have also improved accuracy for beta-sheet content evaluation. The other structures such as alpha-helix do not significantly benefit from side chain contribution subtraction, in some cases prediction is even degraded. We show that co-linearity between secondary structure content and amino acid composition is not a main limitation for improving secondary structure prediction. We also show that, even though based on different criteria, secondary structures defined by DSSP and XTLSSTR both arrive at the same conclusion: only the beta-sheet structure clearly benefits from side chain subtraction. It must be concluded that side chain contribution subtraction benefit for the evaluation of other secondary structure contents is limited by the very rough description of side chain absorbance which does not take into account the variations related to their environment. The study was performed on a large protein set. To deal with the large number of proteins present, we worked on protein microarrays deposited on BaF2 slides and FTIR spectra were acquired with an imaging system.

TBD-Catalyzed Ring-Opening Polymerization of Alkyl-Substituted Morpholine-2,5-Dione Derivatives

In a two-step synthesis, five different alkyl-substituted morpholine-2,5-dione monomers were synthesized from the natural amino acids glycine, alanine, valine, leucine, and isoleucine. The heterocyclic compounds crystallize in a boat-like conformation and are polymerized via 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD)-catalyzed ring-opening polymerization (ROP) in tetrahydrofuran. Well-defined polymers could be obtained from the monomers based on valine, leucine, and isoleucine at a feed ratio of M/I/TBD = 100/1/0.5. Kinetic studies of the ROP reveal that the molar masses and dispersities (D < 1.2) could be well controlled, as confirmed by size exclusion chromatography and H-1 NMR spectroscopy. At conversions above 50%, the polymerization rate decreases and the dispersity slightly increases, presumably due to transesterification. Matrix-assisted laser desorption time-of-flight mass spectrometry indicates the presence of polymer chains with alpha-end groups derived from the initiator. 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 142-25-6 is helpful to your research. Name: N1,N1,N2-Trimethylethane-1,2-diamine.

On the detection of carbon fibre storage contamination and its effect on the fibre-matrix interface

Contamination caused by inappropriate carbon fibre (CF) storage may have an impact on their end use in reinforced composite materials. Due to the chemical complexity of CFs it is not easy to detect potential contaminants, especially at the early stage during manufacturing and handling. In this paper, X-ray Photoelectron Spectroscopy (XPS), Fourier Transform Infrared (FTIR) spectroscopy and Surface Energy Analysis (IGC-SEA) were used to assess the surfaces of CFs stored in polyolefin zip-lock bags for possible contamination. Only after over 2 months in-bag storage, was XPS capable of detecting a minor increase in nitrogen on the CF surface while FTIR revealed the presence of fatty acid amides and fatty acids, both associated with the storage media. However neither of these techniques were sensitive enough to show significant evolution of the amount of contamination as a function of storage time. In contrast, IGC-SEA distinguished surface energy differences between CFs before and after storage. These differences were found to change as a function of storage time, which were attributed to increases in contamination amounts. Single fibre fragmentation tests indicated that the surface contamination had potential to disrupt the fibre-matrix interface. These findings provide a new method for assessing the surface contamination of CFs with potential application to other materials.
