In the present work we synthesized a new series of phenoxyacetohydrazide functional compounds 4a-k and characterized by spectral data. Synthesized compounds were screened in vitro for their antibacterial activity. Compounds 4a, 4j and 4k exhibited inhibitory activity against S. aureus NCIM 5022 with MIC value of 64?μg/ml These compounds also exhibited activity against methicillin resistant S. aureus ATCC 43300 with MIC of 128?μg/ml. Among all the tested compounds 4c and 4j showed highest activity, respectively against B. subtilis NCIM 2545 and K. pneumoniae NCIM 2706. Only one compound i.e. 4d showed activity against another Gram-negative bacteria P. aeruginosa NCIM 2036 with MIC value of 64?μg/ml. Among three tested compounds, 4k exhibited highest inhibitory activity against S. aureus MurD enzyme with IC50 value of 35.80?μM. Further binding interactions of 4a-k with the modelled S. aureus MurD catalytic pocket residues is investigated with the extra-precision molecular docking and binding free energy calculation by MM-GBSA approach. The van der Waals energy term was observed to be the driving force for binding. Further, 50?ns molecular dynamics simulations were performed to validate the stabilities of 4j- and 4k-modelled S. aureus MurD. Graphic abstract: [Figure not available: see fulltext.]

Human African trypanosomiasis (HAT), caused by the parasitic protozoa Trypanosoma brucei, is one of the fatal diseases in tropical areas and current medicines are insufficient. Thus, development of new drugs for HAT is urgently needed. Leucyl-tRNA synthetase (LeuRS), a recently clinically validated antimicrobial target, is an attractive target for development of antitrypanosomal drugs. In this work, we report a series of α-phenoxy-N-sulfonylphenyl acetamides as T. brucei LeuRS inhibitors. The most potent compound 28g showed an IC50 of 0.70 μM which was 250-fold more potent than the starting hit compound 1. The structure-activity relationship was also discussed. These acetamides provided a new scaffold and lead compounds for the further development of clinically useful antitrypanosomal agents.

A family of carbonyl-substituted diphenylpyrimidine derivatives (Car-DPPYs) with strong activity against focal adhesion kinase (FAK), were described in this manuscript. Among them, compounds 7a (IC50 = 5.17 nM) and 7f (IC50 = 2.58 nM) displayed equal anti-FAK enzymatic activity to the lead compound TAE226 (6.79 nM). In particular, compound 7a also exhibited strong antiproliferative activity against several stubborn cancer cells, including AsPC-1 cells (IC50 = 0.105 μM), BxPC-3 cells (IC50 = 0.090 μM), and MCF-7/ADR cells (IC50 = 0.59 μM). Additionally, compound 7a also showed great antitumor efficacy in vivo via aAsPC-1 cancer Xenograft mouse model. The preliminary mechanism study by Western blot analysis revealed that 7a repressed FAK phosphorylation in AsPC cancer cells. Taken together, the results indicate that compound 7a may serve as a promising preclinical candidate for treatment of stubborn cancers.

Two series of ω-phenoxy contained acylhydroxamic acids as novel urease inhibitors were designed and synthesized. Biological activity evaluations revealed that ω-phenoxypropinoylhydroxamic acids were more active than phenoxyacetohydroxamic acids. Out of these compounds, 3-(3,4-dichlorophenoxy)propionylhydroxamic acid c24 showed significant potency against urease in both cell free extract (IC50 = 0.061 ± 0.003 μM) and intact cell (IC50 = 0.89 ± 0.05 μM), being over 450- and 120-fold more potent than the clinically prescribed urease inhibitor AHA, repectively. Non-linear fitting of experimental data (V-[S]) suggested a mixed-type inhibition mechanism and a dual site binding mode of these compounds.

Forty one novel 1,3,4-oxadiazole/thiadiazole thioether derivatives containing phenoxy moiety were designed and synthesized. Bioassay demonstrated that some of them showed remarkable activities against Tylenchulus semipenetrans in vitro and in vivo. Compounds 20, 21, 35 and 39 showed excellent lethal activities after treatment for 48?h in vitro, with LC50 values of 13.4?±?1.8, 11.7?±?2.5, 13.7?±?2.4 and 13.3?±?1.1?mg·L–1, respectively, which were obviously superior to fosthiazate (49.1?±?2.8?mg·L–1) and avermectin (26.6?±?2.3?mg·L–1). Compound 21 can effectively control the citrus nematode disease caused by T. semipenetrans at 200?mg·L–1 in vivo with (68?±?3)% inhibitory effect, which was even better than that of avermectin ((63?±?2)%). The CoMFA and CoMSIA models of three-dimensional quantitative structure-activity relationships (3D-QSARs) were established. The compound 33 was designed based on the 3D-QSAR models with more vigorous nematicidal activities in vitro (LC50?=?9.8?±?1.4?mg·L–1) and in vivo ((70?±?5)%). These results demonstrated that compound 33 can be considered as a potential nematicide.

Six novel 8-hydroxyquinoline derivatives were synthesized using 2-methyl-8-hydroxyquinoline and para-substituted phenol as the main starting materials, and were characterized by 1H nuclear magnetic resonance (NMR), mass spectrometry (MS), ultraviolet (UV) light analysis and infra-red (IR) light analysis. Their complexes with Eu(III) were also prepared and characterized by elemental analysis, molar conductivity, UV light analysis, IR light analysis, and thermogravimetric–differential thermal analysis (TG–DTA). The results showed that the ligand coordinated well with Eu(III) ions and had excellent thermal stability. The structure of the target complex was EuY1–6(NO3)3.2H2O. The luminescence properties of the target complexes were investigated, the results indicated that all target complexes had favorable luminescence properties and that the introduction of an electron-donating group could enhance the luminescence intensity of the corresponding complexes, but the addition of an electron-withdrawing group had the opposite effect. Among all the target complexes, the methoxy-substituted complex (–OCH3) had the highest fluorescence intensity and the nitro-substituted complex (–NO2) had the weakest fluorescence intensity. The results showed that 8-hydroxyquinoline derivatives had good energy transfer efficiency for the Eu(III) ion. All the target complexes had a relatively high fluorescence quantum yield. The fluorescence quantum yield of the complex EuY3(NO3)3.2H2O was highest among all target complexes and was up to 0.628. Because of excellent luminescence properties and thermal stabilities of the Eu(III) complexes, they could be used as promising candidate luminescent materials.
