Some thiocarbamoyl based novel anticathepsin agents

Cathepsins have emerged as important targets in various tissues degenerative disorders due to their involvement in degradation of extracellular matrices and endogenous protein turnover. Elevated cathepsins levels vis-a-vis decreased concentration of endogenous inhibitors has been reported at different diseased sites. The design and synthesis of specific potential anti-cathepsin agents is therefore of great significance. Most of potential anticathepsin agents developed have peptide based structures with an active warhead. Due to oral instability and immunogenic problems related to peptidyl inhibitors drift the synthesis and evaluation of non-peptide cathepsin inhibitors in last two decades. The present work provides a detailed structure activity relationship for developing potential non-peptide anticathepsin agents based on in-vitro inhibition studies of a library of synthesized thio carbamoylnon-peptide inhibitors.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 35344-95-7. Safety of 1H-Pyrazole-4-carbaldehyde.

C-2-Symmetric Cinchona Alkaloid Derivatives: Versatile Catalysts for the Enantioselective C-C Bond Forming Conjugate Addition of Nucleophiles to Simple alpha,beta-Unsaturated Acyl Pyrazoles

A single C-2-symmetric squaramide catalyst system allows the facile addition of either malononitrile or benzyl nitroacetate to simple pyrazole-based Michael acceptors with excellent enantiocontrol and at lower catalyst loadings than previously possible. The latter reactions are not diastereoselective, however facile hydrogenolysis leads to decarboxylation and formation of the formal adduct from the addition of nitromethane (a very recalcitrant nucleophile in this chemistry) with excellent yield and enantiocontrol.

Design and synthesis of boron complexes as new Raman reporter molecules for sensitive SERS nanotags

A new series of boron complexes consisting of pyridine-pyrazole ligands has been designed, synthesized and evaluated for its Raman activity using solid-state Raman spectroscopy. The detailed surface-enhanced Raman scattering (SERS) study of selected dye 2-(3-(pyridin-4-yl)-1H-pyrazol-5-yl) pyridine (P-4) on gold nanoparticles (AuNPs) of size 40 nm revealed that it can detect as small as the nanomole level with signal quality that is superior to structurally similar commercially available reporter molecules (RMs), rendering it a suitable RM for sensitive SERS nanotags.

The structure of compound 1 was characterized by FT-IR, TGA, PXRD and UV-Vis analysis. The magnetic and photoluminescence properties of 1 were also studied. X-ray diffraction analysis showed that the building blocks of 1 form a one-dimensional supramolecule due to the existence of intermolecular interactions such as hydrogen bonds and electrostatic interactions. Antibacterial activity of compound 1 was evaluated against gram-negative and gram-positive bacteria using the agar well diffusion method, OD600 assay and colony formation method. Compound 1 showed very good antibacterial activity in the liquid medium. (C) 2020 Elsevier B.V. All rights reserved.

Experimental and DFT studies on Hexacoordinated acyl(alkyl)and Pentacooordinated Hydroxyalkyl(phosphinite)erhodium(III). Catalytic Hydrolysis of Ammonia Borane

[Rh(nbd)Cl](2) (nbd=norbornadiene) reacts with quinoline-8-carbaldehyde (C9H6NCHO) and pyrazole (Hpz) affording, depending on Rh/Hpz ratio, acyl-alkyl [Rh(mu-Cl)(C9H6NCO)(Hpz)(sigma-C7H9)](2) (1) or [RhCl(C9H6NCO)(Hpz)(2)(sigma-norbornenyl)] (2), stereoselectively as confirmed by DFT calculations. Hydrogen bond between NH-pyrazole and O-acyl occurs. 1 and 2 react with diphenylphosphine oxide (SPO) giving 16e [RhCl(C9H6NC(nbyl))(Ph2PO)(Hpz)] (3) through SPO kappa(1)-P-coordination, C-C bond coupling between acyl and norbornenyl and outer-sphere O(P)-to-O(C) hydrogen transfer. 3 shows distorted trigonal bipyramidal structure with weak intramolecular (C)-OH…O(=P) and NH…Cl hydrogen bonds. DFT calculations indicate this 16e structure being favoured by sigma- and pi-type orbital multi-overlapping between pyrazole and both the OH…O and chlorine and by intermolecular forces in the crystal. Solutions of 3 contain an equilibrium between trigonal bipyramid and a square-planar pyramid with OH interacting with phosphoryl and NH, confirmed by DFT C-13 NMR calculations. 1 is very efficient homogeneous catalyst for H3N-BH3 hydrolysis to release hydrogen under air.

Enhanced Optoelectronic and Biological Potential of Virescent-Glowing Terbium(III) Complexes with Pyrazole Acid

A series of five virescent color emitting terbium(III) complexes is fabricated by a cost-effective and eco-friendly solution precipitation technique with the utilization of 1-(4-methoxyphenyl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic acid (L) as a primary ligand and highly conjugated nitrogen donor secondary ligands such as bathophenanthroline (batho), 5,6-dimethyl-1,10-phenanthroline (dmph), 1,10-phenanthroline (phen) and 2,2-bipyridyl (bipy). The elemental compositions of complexes are examined through energy dispersive x-ray and elemental analyses, whilst the binding nature of ligand with terbium(III) ion is confirmed using proton nuclear magnetic resonance and infrared spectroscopy. The band gap energy (E-g) of complexes is found in the range of 3.85-3.34 eV as evaluated from diffuse reflectance spectral data. The significant thermal stability of these luminescent materials (157 degrees C) demonstrates their key role as virescent component in white organic light emitting diodes. The intense emission and decay time of complexes are explored through photoluminescent study. The good color purity and Commission International De I’Eclairage color coordinates promise the enhanced performance of these materials in lighting appliances. The sensitization phenomenon highlights the role of ligands in increasing the luminescence intensity of complexes. The biological assessment indicates that the complexes are potent antimicrobial and antioxidant agents. The aforementioned features extend the field of applications of complexes in laser technology and optoelectronic devices.

Synthesis and evaluation of antimicrobial and anticancer activities of 3-phenyl-1-phenylsulfonyl pyrazoles containing an aminoguanidine moiety

A series of 3-phenyl-1-phenylsulfonyl pyrazoles containing an aminoguanidine moiety was designed, synthesized, and evaluated for their antimicrobial and anticancer activities. The majority of the target compounds showed broad-spectrum antimicrobial activity against the tested strains, with minimum inhibitory concentration (MIC) values ranging from 2 to 64 mu g/ml. Compound5k, showing the most potent antimicrobial activity againstBacillus subtilisCMCC 63501 and multidrug-resistantStaphylococcus aureusATCC 43300 with an MIC value of 2 mu g/ml, was the most promising one in this series. It was also effective forS. aureusATCC 33591 and multidrug-resistantEscherichia coliATCC BAA-196 at higher concentrations. The bactericidal time-kill kinetics test illustrated that compound5khad rapid bactericidal potential. Docking results exhibited that compound5kshowed various kinds of binding to the FabH receptor, reflecting that5kcould bind with the active site well. All compounds showed excellent activity against the investigated cancer cells, with IC(50)values ranging from 1.90 to 54.53 mu M. Among them, compound5fshowed prominent cytotoxicity with IC50 = 1.90 mu M against A549 cells, while exhibiting lower inhibitory activity against 293T cells (IC50 = 41.72 mu M), indicating that it has the potential for a good therapeutic index as an anticancer drug.
