Synthesis, Characterization and Docking Studies of N-Methyl-2, 3-Dihydro Quinazolin-4-Ones Linked 1,3-Thiazole Hybrids as Potent Anti-Tubercular Agents

Quinazolin-4-ones connected 1, 3-thiazole were found with antibacterial action after high throughput screening. N-Methyl Anthranilic acid when treated with thiophene-2-carboxylic acid gives 1-Methyl-2(thiophen-2-yl)-1,2-dihydro-4H-3,1-Benzoxazin-4-one which on further treatment with 4-substituted phenyl-1,3-thiazol-2-amines gives 1-Methyl-3-(4-Substituted phenyl-1,3-thiazol-2yl)-2-(thiophen-2-yl)-2,3-dihydro quinazoline-4(1H)-ones (5Fa1-5Fk11) were obtained. The structural identification was done through Infra-red, H-1- Nuclear magnetic resonance, C-13- Nuclear magnetic resonance, and Mass spectrometry. These derivatives were screened for anti-tubercular activity against Mycobacterium tuberculosis H37RV using the micro plate alamar blue assay method. Compounds 5Ff6, 5Fe5, 5Fb2, and 5Fd4 displayed better antibacterial activity at minimum inhibitory concentration 12.5 and 6.25 mu g/ml. Further, 5Ff6 displayed a favourable inhibition at minimum inhibitory concentration 6.25 mu g/ml, contrasted with the reference drug Isoniazide. The compounds were docked where they exhibited associations with both the vital site of penicillin-binding protein 2a and Mycobacterium tuberculosis H37Rv organism. All the derivatives showed good affinity towards the protein when compare with the standard drug. Here 5Ff6 was observed to interact with three amino acids, viz., Agn104, Lys273, and Tyr297, as signified by the great interaction energy (Delta G=-4.2 kcal/mol).

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 38894-11-0 is helpful to your research. Formula: C8H12ClN3OS.

Design, synthesis and biological assessment of new selective COX-2 inhibitors including methyl sulfonyl moiety

Nonsteroidal anti-inflammatory drugs (NSAIDs) cause peptic lesions in the gastrointestinal mucosa by inhibiting the cyclooxygenase-1 (COX-1) enzyme. Selective COX-2 inhibition causes decreased side effects over current NSAIDs. Therefore, the studies about selective inhibition of COX-2 enzyme are very important for new drug development. The design, synthesis and biological activity evaluation of novel derivatives bearing thiazolylhydrazine-methyl sulfonyl moiety as selective COX-2 inhibitors were aimed in this paper. The structures of synthesized compounds were assigned using different spectroscopic techniques such as H-1 NMR, C-13 NMR and HRMS. In addition, the estimation of ADME parameters for all compounds was carried out using in silico process. The evaluation of in vitro COX-1/COX-2 enzyme inhibition was applied according to the fluorometric method. According to the enzyme inhibition results, synthesized compounds showed the selectivity against COX-2 enzyme inhibition as expected. Compounds 3a, 3e, 3f, 3g, 3i and 3j demonstrated significant COX-2 inhibition potencies. Among them, compound 3a was found to be the most effective derivative with an IC50 value of 0.140 +/- 0.006 mM. Moreover, it was seen that compound 3a displayed a more potent inhibition profile at least 12-fold than nimesulide (IC50 = 1.684 +/- 0.079 mu M), while it showed inhibitory activity at a similar rate of celecoxib (IC50 = 0.132 +/- 0.005 mu M). Molecular modelling studies aided in the understanding of the interaction modes between this compound and COX-2 enzyme. It was found that compound 3a had a significant binding property. In addition, the selectivity of obtained derivatives on COX-2 enzyme could be explained and discussed by molecular docking studies. (C) 2020 Elsevier Masson SAS. All rights reserved.

An Efficient Precatalyst Approach for the Synthesis of Thiazole-Containing Conjugated Polymers via Cu-Catalyzed Direct Arylation Polymerization (Cu-DArP)

Over the past decade, direct arylation polymerization (DArP) has emerged as a facile and sustainable methodology for the synthesis of conjugated polymers. Recently, we developed Cu-catalyzed DArP (Cu-DArP) as a low-cost, Pd-free synthetic pathway, which enables conjugated polymers to be synthesized with high molecular weights and minimization of defects. However, the lack of study on the use of Cu-precatalysts in small-molecule direct arylation poses significant limitations for Cu-DArP to potentially overtake conventional Pd-catalyzed methodology, such as the low solubility and stability of the previously employed Cul. Therefore, in this report, we decide to explore the utility of a well-defined, easy-to-prepare, highly soluble, and stable precatalyst, Cu(phen)(PPh3)Br, as an alternative to the Cul, 1,10-phenanthroline catalytic system previously used for Cu-DArP. Herein, we report a drastic improvement of Cu-DArP methodology for the synthesis of 5,5′-bithiazole (5-BTz)-based conjugated polymers enabled by an efficient precatalyst approach, affording polymers with good M-n (up to 163 kDa) and excellent yields (up to 79%). H-1 NMR studies reveal the exclusion of homocoupling defects, which further verifies the excellent stability of Cu(phen)(PPh3)Br compared to CuI. Furthermore, we were able to decrease the catalyst loading from 15 mol % to only 5 mol % (M-n of 11.8 kDa, 64% yield), which is unprecedented when aryl bromides are employed for Cu-DArP. Significantly, 5-BTz was shown to be inactive under various of Pd-DArP conditions, which demonstrates the high compatibility of Cu-DArP as the only pathway for the C-H activation of the 5-BTz unit and a clear case demonstrating an advantage of Cu-DArP relative to Pd-DArP.

Synthesis of GluN2A-selective NMDA receptor antagonists with an electron-rich aromatic B-ring

Glutamatergic N-Methyl-D-aspartate (NMDA) receptors are heterotetrameric ion channels that can be comprised of different subunits. GluN2A subunit-containing NMDA receptors are associated with diseases like anxiety, depression, and schizophrenia. However, the exact contribution of these NMDA receptor subtypes is still unclear. To understand better the role of the GluN2A-containing receptors, novel ligands were designed. In co-crystallization with the isolated binding site, TCN-201 (1) and analogs adopt a U-shape conformation with parallel orientation of rings A and B. In order to increase the pi/pi-interactions between these rings, ring B of TCN-201 was replaced bioisosterically by different electron-rich thiazole, oxazole, and isoxazole heterocycles. The inhibitory activity was measured by two-electrode voltage clamp experiments with Xenopus laevis oocytes expressing GluN2A-containing NMDA receptors. It was found that 21c, 31a, 37a, and 37b were able to inhibit the ion channel. The isoxazole derivative 37b was the most potent negative allosteric modulator displaying 40% of the TCN-201 activity at a concentration of 10 mu M. (c) 2020 Elsevier Masson SAS.

Effect of cocoa roasting time on volatile composition of dark chocolates from different origins determined by HS-SPME/GC-MS

In this study the volatile composition of six samples of dark chocolates varying in the cocoa roasting time (30.5, 34.5 and 38.5 min) and geographical origin (Ecuador and Ghana) was characterized by headspace solid-phase microextraction (HS-SPME) followed by gas chromatography-mass spectrometry (GC-MS). One hundred and twenty-one different compounds were identified using a carboxen/polydimethylsiloxane (CAR-PDMS) fiber comprising acids, alcohols, aldehydes, alkanes, esters, furans, ketones, nitrogen compounds, pyran derivatives, pyrazines, pyrroles and thiazoles. The effect of roasting time on the volatile composition of chocolates depended on their geographical origin. Principal component analysis (PCA) was applied to volatile composition of the six dark chocolate samples. Eight different groups of compounds were established according to the position of the aroma compounds on the PC plot and accordingly to variation among samples. Therefore, volatile compounds that appeared or disappeared during roasting of cocoa from each origin or both origins were identified.

New Aspects of Monoamine Oxidase B Inhibitors: The Key Role of Halogens to Open the Golden Door

A large plethora of drugs and promising lead compounds contain halogens in their struc-tures. The introduction of such moieties strongly modulates their physical-chemical features as well as pharmacokinetic and pharmacodynamic profile. The most important outcome was shown to be the ability of these halogens to favourably influence the drug-target interaction and energetic stability within the active site by the establishment of halogen bonds. This review attempted to demonstrate the key role exerted by these versatile moieties when correctly located in an organic scaffold to display Monoamine Oxidase (MAO) inhibition and selectivity towards the B isoform of this important enzyme. Human MAOs are well-recognized as therapeutic targets for mood disorders and neurodegenerative diseases and medicinal chemists were prompted to discover the structural requirements crucial to discriminate the slight differences between the active sits of the two isoforms (MAO-A and MAO-B). The analysis of the structure-activity relationships of the most important scaffolds (hydrazothia- zoles, coumarins, chromones, chalcones, pyrazolines) and the impact of halogen (F, Cl, Br and I) insertion on this biological activity and isozyme selectivity have been reported being a source of inspiration for the medicinal chemists.

Synthesis, molecular docking and ADME studies of thiazole-thiazolidinedione hybrids as antimicrobial agents

New thiazole-thiazolidinedione hybrids (5a-k) were efficiently synthesized and evaluated for their in-vitro antimicrobial activity against four fungal and bacterial strains. The chemical structures of the compounds were elucidated by FTIR, H-1 NMR, and C-13 NMR spectral data. Most of the synthesized compounds were sensitive against gram positive, gram negative bacterial and fungal strains. Among the synthesized molecules, compounds 5h, and 5i exhibited promising inhibitory activity against all selected fungal strains and gram positive bacteria namely, Staphylococcus aureus, and Enterococcus faecalis. The molecular docking results predicted that the thiazole-thiazolidinedione derivatives bind to the active site protein ATP-binding pocket from E. coli, S. aureus and C. albicans with good interaction energy scores. Ct-DNA was used to evaluate the binding interactions of the selected compounds by means of absorption spectroscopy. To further characterize the drug-likeness and ADME properties were calculated using the Qikprop, the result of present study suggests that thiazole-thiazolidinedione hybrid could be an interesting approach for the design of new antimicrobial agents.

Breaking the axiality of pentagonal-bipyramidal dysprosium(iii) single-molecule magnets with pyrazolate ligands

A range of pyrazolate-based ligands have been used to balance the multidentate-chelating feature and the magnetic axiality in destroyed pentagonal-bipyramidal (DPB) dysprosium(iii) single-molecule magnets (SMMs). This family of complexes are air-stable and share the general formulae of [(DyXX2)-X-1(L-eq)(5)][BPh4], where X-1 and X-2 are the anionic axial ligands, including pyrazolate-based ligands and chloride; L-eq is the equatorial solvent molecule such as tetrahydrofuran (THF), pyridine (py) and thiazole (NS). Compared to the prototype PB SMMs, the bidentate-chelating features of the pyrazolate ligands show, albeit slow magnetic relaxation behavior, a much smaller energy barrier for magnetization reversal (U-eff). Static electronic calculation shows that the magnetic axiality above the ground m(J) = +/- 15/2 states has been much reduced, leading to the mixing of other states at higher levels. Nevertheless, this systematic study reveals that the variation of the substituents on the pyrazolate ligands and the replacement of planar solvents are effective at influencing the magnetic relaxation behavior. We found that the chloride coordinating mono-pyrazolate complexes, such as [(DyXCl)-Cl-1(THF)(5)][BPh4] (X-1 = 3-(trifluoromethyl)pyrazole (tfpz) 1, X-1 = 3-methylpyrazole (Mepz) 2, X-1 = 3-isopropyl-1H-pyrazole (Iprpz) 3, X-1 = 3,5-dimethylpyrazole (Me(2)pz) 4, X-1 = 3,5-diisopropylpyrazole (Ipr(2)pz) 5, and X-1 = pyrazole (pz) 6, generally show lower U-eff, while bi-pyrazolate complexes, such as [Dy(tfpz)(2)(THF)(5)][BPh4] 7, [Dy(pz)(2)(THF)(5)][BPh4] 8, [Dy(pz)(2)(py)(5)][BPh4]center dot 2py 9 and [Dy(pz)(2)(NS)(5)][BPh4] 10, show higher U-eff. Among them, 8 shows the largest U-eff of 521(8) K and a comparable open hysteresis temperature of similar to 5 K (at a field sweeping rate of 12 Oe s(-1)) with 9 and 10. The enhanced blocking temperature for 8 is different from that for the PB Dy(iii) SMMs in which the py ligand can cause a much higher hysteresis temperature than the one coordinated with THF due to the aromatic pi-pi interactions, indicating that the bis-bidentate-chelating Dy(iii) ion is rigid enough to reduce the influence from the equatorial ligands. Moreover, substitution with electron-withdrawing groups such as the -CF3 group reduces U-eff prominently. Such a clear magnetostructural correlation in Dy(iii) SMMs is fundamentally important, indicating that a subtle balance between magnetic axiality and molecular rigidity is critical to design high-performance Dy(iii) SMMs.
