A combine approach of chemical synthesis, biological evaluation and structural dynamics studies revealed thiazole substituted arylamine derivatives as potent FabH enzyme inhibitors

Bacterial FabH enzyme is a broad-spectrum antimicrobial target and can be used in the design of novel antibiotics. This study reports chemical synthesis of thiazole based amine compounds as FabH inhibitors, followed by biological evaluation, and computational drug designing analysis with ultimate objective to guide further biological optimization of the identified hits. The compounds were synthesized through Pd-PEPPSI catalyzed cross coupling strategy for the Buchwald-Hartwig amination of thiazole-substituted aryl bromide. Pd-PEPPSI pre catalysts were utilized for the cross couple with the diverse range of functionalized electron-deficient and electron-rich anilines and aliphatic amines. The thiazole based heteroaryl bromide coupling was found to be challenging and only specialized Pd-PEPPSI-IPr and Pd-PEPPSI-IPent catalysts were found to be effective providing the coupling product yield in the range of 78% to 99%. Biological investigation depicted compound 3f to be effective against Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermis, and Escherichia coli with mean + standard deviation value of 9.6 +/- 0.4, 11.6 +/- 0.4, 15.6 +/- 0.4, and 11.6 +/- 0.4, respectively. This compound is also active against free radicals with EC90 value of 39.45 mu g/ml. Comparative docking predictions unravel the 3f binding mode at FabH active tunnel as such to block complete access for the natural substrate and involved balanced hydrogen and hydrophobic interactions. FabH-3f complex dynamics in solution found the docked conformation between the protein and compound of higher stability with mean carbon alpha deviation of 1.87 angstrom and mean residual deviation of 0.88 angstrom. Intermolecular interactions analysis depicted Asn274 from FabH active pocket to be significant in compound holding and strengthening of interaction as the simulation progresses. This was supported further by radial distribution function (RDF) and axial frequency distribution (AFD) that demonstrated the high distribution of compound atoms in close proximity of Asn274 residue and decrease in interaction distance. Further, the docking and simulation findings were validated through MMPB/GBSA methods that complements the compound affinity for the said target. In a nutshell, the identified hit could be subjected to structure, biological and pharmacokinetic optimization for development of effective FabH inhibitors.

Thiazole-tetheredbiaryls as fluorescent chemosensors for the selective detection of Fe(3+)ions

3-Amino-5-(thiazol-2-yl)-[1,1 ‘-biaryl]-2,4-dicarbonitriles have been synthesized employing a facile one-pot pseudo four-component domino strategy. All these thiazole-tethered biaryls exhibited blue fluorescence under UV lamp. Based on the high relative quantum yield, three compounds namely,4a,4d, and4i, were chosen to explore the metal interference studies. Against several metal ions, these three thiazole-tethered biphenyl probes were found to be effective fluorescent chemosensors for the selective and sensitive detection of Fe(3+)ions with a lower detection limit of 0.18, 0.12, and 0.16 mu M, respectively.

High temperature membranes based on PBI/sulfonated polyimide and doped-perovskite nanoparticles for PEM fuel cells

A new sulfonated aromatic diamine monomer containing nitrogen heterocycles was synthesized and employed to prepare a novel sulfonated polyimide (SPI). To develop proton exchange membranes, new nanocomposite blend membranes consist of the prepared SPI and polybenzimidazole (PBI) were fabricated with incorporation of SrCe0.9Yb0.1O3-delta (SCYb) doped-perovskite nanoparticles with a solution-casting method. The goal of this work is to study the effect of SPI and SCYb doped-perovskite nanoparticles on the important parameters of the PBI membrane specially proton conductivity and fuel cell performance. The proton conductivity and phosphoric acid doping level of the PBI-SPI-SCYb nanocomposite blend membranes improved due to an interaction of -SO3H group and thiazole rings of SPI and N-H groups of PBI in the oxygen vacancies of SCYb doped-perovskite nanoparticles. Substitution of Ce4+ by Yb3+ in the SCYb doped-perovskite nanoparticles produce oxygen vacancies and decrease the columbic repulsion between protons and positive ions. Furthermore at highest phosphoric acid doping level of 14 mol phosphoric acid per monomer unit, the nanocomposite blend membranes displayed proton conductivity of 131 mS/cm at 180 degrees C and 8% relative humidity. The increase in power density from 0.31 W/cm(2) in PBI-SPI blend membranes (SPI/PBI: 25 wt%) to 0.59 W/cm(2) in PBI-SPI-SCYb nanocomposite blend membranes (SPI/PBI: 25 wt% and 7 wt% of SCYb) was achieved at 0.5 V, 8% RH and 180 degrees C, which demonstrates that these developed nanocomposite blend membranes have a high potential to be regarded as the most promising candidates for high-temperature fuel cell with improved proton conductivity.

Assessing the nucleophilic character of 2-amino-4-arylthiazoles through coupling with 4,6-dinitrobenzofuroxan: Experimental and theoretical approaches based on structure-reactivity relationships

A kinetic study of the reactions of potentially bioactive 2-amino-4-arylthiazoles with highly reactive 4,6-dinitrobenzofuroxan (DNBF) is reported herein in acetonitrile solution. The complexation reaction was followed by recording the UV-vis spectra with time at lambda(max )= 482 nm. Electronic effects of substituents influencing the rate of reaction have been studied using structurereactivity relationships. It is shown that the Hammett plot relative to the reaction of DNBF with 2-amino-4-(4-chlorophenyl)thiazole exhibit positive deviation from the log k(1) versus c correlation, while it showed excellent linear correlation in terms of Yukawa-Tsuno equation. It has be noticed that the nonlinear Hammett plot observed for 2-amino-4-(4-chlorophenyl) thiazole is not attributed to a change in rate-determining step but is due to nature of electronic effect of substituent caused by the resonance of stabilization of substrates. The second-order rate constant (k(1)) relating to the bond C-C and C-N forming step of the complexation processes of DNBF with 4-substituted-aminothiazoles and 2-amino-5-methyl-4-phenylthiazole, respectively, is fit into the linear relationship log k = S-N (N + E), thereby permitting the assessment of the nucleophilicity parameter (N) of the 2-amino-4-arylthiazoles of the range (4.90 < N < 6.85). 2-amino-4-arylthiazoles is subsequently ranked by positioning its reactivity on the general nucleophilicity scale developed recently by Mayr and coworkers (2003) leading an interesting and a direct comparison over a large domain of pi-, sigma-, and n-nucleophiles. The global electrophilicity/nucleophilicity reactivity indexes of the 2amino-4-arylthiazoles have been investigated by means of a density functional theory (DFT) method. . (C) 2020 The Authors.

Azole as privileged heterocycle for targeting the inducible cyclooxygenase enzyme

An over-expression of COX-2 isoenzyme belonging to the Cyclooxygenase Enzyme Family triggers the overproduction of pro-inflammatory prostaglandins that instigate the development of chronic inflammation and related disorders. Hence, the rationally designed drugs for mitigating over-activity of COX-2 isoenzyme play a regulatory role toward the alleviation of the progression of these disorders. However, a selective COX-2 inhibition chemotherapy prompts several side effects that necessitate the identification of novel molecular scaffolds for deliberating state-of-the-art drug designing strategies. The heterocyclic azole scaffold, being polar and hydrophilic, possesses remarkable physicochemical advantages for designing physiologically active molecules capable of interacting with a wide range of biological components, including enzymes, peptides, and metabolites. The substituted derivatives of azole nuclei enable a comprehensive SAR analysis for the appraisal of bioactive profile of the deliberated molecules for obtaining the rationally designed compounds with prominent activities. The comprehensive SAR analysis readily prompted the identification of Y-shaped molecules and the eminence of bulkier group for COX-2 selective inhibition. This review presents an epigrammatic collation of the pharmacophore-profile of the chemotherapeutics based on azole motif for a selective targeting of the COX-2 isoenzyme.

Convergent synthesis of carbonic anhydrase inhibiting bi-heterocyclic benzamides: Structure-activity relationship and mechanistic explorations through enzyme inhibition, kinetics, and computational studies

By using a convergent methodology, a novel series of N-arylated 4-yl-benzamides containing a bi-heterocyclic thiazole-triazole core was synthesized, and the structures of these hybrid molecules, 9a-k, were corroborated through spectral analyses. The in vitro studies of these multifunctional molecules demonstrated their potent carbonic anhydrase inhibition relative to the standard used. The kinetics mechanism was exposed by Lineweaver-Burk plots, which revealed that 9j inhibited carbonic anhydrase non-competitively by forming an enzyme-inhibitor complex. The inhibition constants K-i calculated from Dixon plots for this compound was 1.2 mu M. The computational study was also persuasive with the experimental results, and these molecules disclosed good results of all scoring functions and interactions, which suggested a good binding to carbonic anhydrase. So, it was predicted from the inferred results that these molecules might be considered as promising medicinal scaffolds for various diseases related to the uncontrolled production of this enzyme.

Design, synthesis, and fungicidal evaluation of novel oxysterol binding protein inhibitors for combatting resistance associated with oxathiapiprolin

Oxathiapiprolin, the first successful oxysterol binding protein (OSBP) inhibitor for oomycete control, is regarded as an important milestone in the history of fungicide discovery. However, its interaction with OSBP remain unclear. Moreover, some plant pathogenic oomycetes have developed medium to high resistance to oxathiapiprolin. In this paper, the three-dimensional (3D) structure of OSBP from Phytophthora capsici (pcOSBP) was built, and its interaction with oxathiapiprolin was systematically investigated by integrating molecular docking, molecular dynamics simulations, and molecular mechanics Poisson-Boltzmann surface area (MM/PBSA) calculations. The computational results showed that oxathiapiprolin bound to pcOSBP forms H-bonds with Leu73, Lys74, Ser69, and water molecules. Then, based on its interaction with pcOSBP, oxathiapiprolin was structurally modified to discover new analogs with high fungicidal activity and a low risk of resistance. Fortunately, compound 1e was successfully designed and synthesized as the most potent candidate, and it showed a much lower resistance risk (RF < 1) against LP3-M and LP3-H in P. capsici. The present work indicated that the piperidinyl-thiazole-isoxazoline moiety is useful for further optimization. Furthermore, compound 1e could be used as a lead compound for the discovery of new OSBP inhibitors. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 76824-35-6 help many people in the next few years. COA of Formula: C8H15N7O2S3.

Here, we have established a new and simple synthetic approach to the pentacycloundecane containing cage oxazole unit in four steps. The synthesis begun with a cheap and readily available materials such as 2,5-dimethoxybenzaldehyde and endo-dicyclopentadiene. This approach relies on Van Leusen oxazole synthesis and [2+2] photocycloaddition as key steps. To the best of our knowledge, this is the first example of Cookson’s dione containing oxazole ring system. Some of these oxazole motifs are useful in bioorganic chemistry and our results are likely to draw the attention of medicinal chemists
