A novel series of 1,3-benzoxazole and 1,3-dioxolane substituted benzimidazole-based N-heterocyclic carbene (NHC) precursors (6a-b and 11a-b) and their corresponding NHC-silver(I) acetate (12a-b and 14a-b) and bis-NHC-silver(I) hexafluorophosphate complexes (13a-b and 15a-b) were synthesized and characterized by H-1 NMR, C-13 NMR, ATR-IR spectroscopic methods and elemental analysis techniques. Also, the molecular structure of benzimidazolium salt (6a) and bis-NHC-silver(I) hexafluorophosphate complex (13b) were unambiguously established by single crystal X-ray diffraction analysis. Fascinatingly, bis-NHC-silver(I) hexafluorophosphate complex (13b) was revealed to be dinuclear in nature. All the azolium salts (6a-b and 11a-b) as well as the corresponding silver(I) complexes (12a-b, 13a-b, 14a-b and 15a-b) were evaluated for their antimicrobial potential against Gram positive (Staphylococcus aureus), and a set of Gram negative (Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) bacterial strains and two fungi, Candida albicans and Cryptococcus neoformans. Antimicrobial studies revealed the comparable activities of benzimidazolium salts (6a-b and 11a-b) and the silver(I) complexes (12a-b, 13a-b and 15a-b). Whereas, the 1,3-dioxolane substituted benzimidazole-based silver(I) acetate complexes (14a-b) demonstrated excellent potentials with both bacterial and fungal growth inhibition above 95%.

New discoveries in chemical research and development in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals.

Now introduce a scientific discovery about this category.

In the present study, we attempted to develop novel class of Mycobacterium tuberculosis (Mtb) inhibitors by exploring the pharmaceutically underexploited enzyme targets which are majorly involved in cell wall biosynthesis of mycobacteria. For this purpose glutamate racemase was selected which racemizes D-glutamate from L-glutamate, a key step in peptidoglycan synthesis. Furthermore, enzyme is neither expressed nor its product, n-glutamate is produced in mammals, and hence inhibiting this enzyme will have no vulnerable effect in host organism. A library of our in-house compounds were screened against glutamate racemase using a biophysical technique; thermal shift assay and further by enzyme inhibition assay to identify Lead 1 molecule. Lead 1 optimization and expansion resulted in twenty four compounds. Among the synthesized compounds twelve compounds shown good enzyme inhibition than Lead 1 (IC50 20.07 +/- 0.29 mu M). Among all the compounds; compound 22 (IC50 1.1 +/- 0.52 mu M) showed potent non-competitive mode of inhibition in enzyme assay. Further showed good susceptibility (in replicating bacteria) of MIC 8.72 mu M and bactericidal time dependant kill on dormant culture. It also exhibited significant activity in Mtb nutrient starvation model (2.5) and Mtb biofilm model (2.4) and in vivo M. marinum infected Zebra fish model studies (3.6) reduction at logarithmic scale.

2-Substituted 4H-chromeno[3,4-d]oxazol-4-ones are prepared from 4-hydroxy-3-nitrocoumarin and acids by one-pot reaction in the presence of PPh3 and P2O5 under microwave irradiation or by onepot two-step reactions in the presence of Pd/C and hydrogen and then P2O5 under microwave irradiation. The fused oxazolocoumarins were also synthesized from 3-amido-4-hydroxycoumarins and P2O5 under microwave irradiation. The 3-amido-4-hydroxycoumarins are obtained almost quantitatively from 4-hydroxy-3-nitrocoumarin, acids and PPh3 under microwave irradiation, or in the presence of Pd/C and H-2 on heating. Preliminary biological tests indicate significant inhibition of soybean lipoxygenase and antilipid peroxidation for both oxazolocoumarins and o-hydroxyamidocoumarins.

In this paper, new liquid crystal compounds with negative dielectric anisotropy were synthesised by regulating the substituents on the benzofuran ring. Their structures were confirmed by(1)H-nuclear magnetic resonance,(CNMR)-C-13 and mass spectra. The effects of substituent on the properties of liquid crystals were investigated. Compared with the reference compounds, the compounds with 5-ethoxy-6,7-difluorobenzofuran ring exhibit higher clearing points as well as the tendency of expansion of SmA phase range. The density functional theory calculation results reveal that the 6-ethoxy-7-fluorobenzofuran-based compound has smaller aspect ratio than that of the 5-ethoxy-6,7-difluorobenzofuran-based compound, which results in the diminish of the mesophase. Although the dielectric anisotropy of the 5-ethoxy-6,7-difluorobenzofuran-based compound is slightly lower than that of the reference compound, it has both the largest perpendicular and parallel dielectric constant.

Structure based designing of benzimidazole/benzoxazole derivatives as anti-leishmanial agents

Folates are essential biomolecules required to carry out many crucial processes in leishmania parasite. Dihydrofolate reductase-thymidylate synthase (DHFR-TS) and pteridine reductase 1 (PTR1) involved in folate biosynthesis in leishmania have been established as suitable targets for development of chemotherapy against leishmaniasis. In the present study, various computational tools such as homology modelling, pharmacophore modelling, docking, molecular dynamics and molecular mechanics have been employed to design dual DHFR-TS and PTR1 inhibitors. Two designed molecules, i.e. 2-(4-((4-nitrobenzyl)oxy)phenyl)-1H-benzo[d]imidazole and 2-(4-((2,4-dichlorobenzyl)oxy)phenyl)-1H-benzo[d]oxazolemolecules were synthesized. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay was performed to evaluate in vitro activity of molecules against promastigote form of Leishmania donovani using Miltefosine as standard. 2-(4-((4-nitrobenzyl)oxy)phenyl)-1H-benzo[d]imidazole and 2-(4-((2,4-dichlorobenzyl)oxy)phenyl)-1H-benzo[d]oxazolemolecules were found to be moderately active with showed IC50 = 68 +/- 2.8 mu M and 57 +/- 4.2 mu M, respectively.

Encapsulation of Risperidone by Methylated beta-Cyclodextrins: Physicochemical and Molecular Modeling Studies

Risperidone (RSP) is an atypical antipsychotic drug which acts as a potent antagonist of serotonin-2 (5TH2) and dopamine-2 (D2) receptors in the brain; it is used to treat schizophrenia, behavioral and psychological symptoms of dementia and irritability associated with autism. It is a poorly water soluble benzoxazole derivative with high lipophilicity. Supramolecular adducts between drug substance and two methylated beta-cyclodextrins, namely heptakis(2,6-di-O-methyl)-beta-cyclodextrin (DM-beta-CD) and heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin (TM-beta-CD) were obtained in order to enhance RSP solubility and improve its biopharmaceutical profile. The inclusion complexes were evaluated by means of thermoanalytical methods (TG-thermogravimetry/DTG-derivative thermogravimetry/HF-heat flow), powder X-ray diffractometry (PXRD), universal-attenuated total reflectance Fourier transform infrared (UATR-FTIR), UV spectroscopy and saturation solubility studies. Job’s method was employed for the determination of the stoichiometry of the inclusion complexes, which was found to be 2:1 for both guest-host systems. Molecular modeling studies were carried out for an in-depth characterization of the interaction between drug substance and cyclodextrins (CDs). The physicochemical properties of the supramolecular systems differ from those of RSP, demonstrating the inclusion complex formation between drug and CDs. The RSP solubility was enhanced as a result of drug encapsulation in the CDs cavity, the higher increase being obtained with DM-beta-CD as host; the guest-host system RSP/DM-beta-CD can thus be a starting point for further research in developing new formulations containing RSP, with enhanced bioavailability.

Novel benzoxazole derivatives featuring rhodanine and analogs as antihypergycemic agents: synthesis, molecular docking, and biological studies

A novel series of benzoxazolyl linked benzylidene based rhodanine and their cyclic analogs were synthesized, characterized and evaluated for their alpha-amyloglucosidase inhibitory activity. Out of eight target compounds, two compounds (4b and 5b) displayed potent inhibitory activity against alpha-amyloglucosidase with IC50 values in the range of 0.24 +/- 0.01-0.94 +/- 0.01 A mu M as compared to standard drug acarbose. Among all the tested compounds, compound 5b containing rhodanine at 3-position of phenyl was found to be the most active inhibitor of alpha-amyloglucosidase. Docking studies showed the existence of potential H-bonding interactions between synthesized compounds and alpha-glucosidase which might be responsible for good biological activity.
