Design, Synthesis, and Antimicrobial Activity of Novel Fluorine-Containing Imidazolones

Abstract: A simple synthetic protocol have been developed for the preparation of novelN-(4-benzylidene-5-oxo-2-phenyl-4,5-dihydro-1H-imidazol-1-yl)-N′-phenylthiourea derivatives by the reaction of4-benzylidene-2-phenyl-4,5-dihydro-1,3-oxazol-5-ones with N

Base Induced Condensation of Malononitrile with Erlenmeyer Azlactones: An Unexpected Synthesis of Multi-Substituted Δ2-Pyrrolines and Their Cytotoxicity

An efficient, metal free approach to synthesize multi-substituted Δ2-pyrroline derivatives by mild base catalyzed cyclocondensation of malononitrile with Erlenmeyer azlactones via 1,2 addition was developed. The modularity of this reaction was used to assemble a range of poly-substituted pyrrolines. Further, synthesized products were screened for cytotoxic properties on different cancer cell lines such as A549 (Human lung adenocarcinoma cells), HeLa (Human cervical adenocarcinoma cells), Jurkat (Human chronic myeloid leukemia cells) and K562 (Human leukemic T cell Lymphoblast cells). Among the synthesized library of compounds, 6f and 6q displayed potent cytotoxic activity.

Benzothiazol clubbed imidazol-4-ones as anti-fungal, anti-tubercular and anti-HIV-1 agents: Their synthesis and molecular docking study

Background: The present work describes antimicrobial, antimycobacterium and anti HIV-1 evaluation of newly synthesized 5-(4-Substituted-benzylidene)-3-[4-(5-methyl-benzothiazol2-yl)-phenyl]-2-phenyl-3,5-dihydro-imidazol-4-one (4a-o). The docking studies were performed in order to predict the potential binding affinities. Objective: The major aim of this study is to develop the new class of bezylidine candidate clubbed with benzothiazole with less toxicity and improved potency as antimicrobial, antitubercular and anti HIV-1. Methods: The titled compounds were characterized by spectral studies (IR, 1H NMR, 13C NMR and Mass). In vitro antimycobacterium activity was carried out using Lowenstein-Jensen medium method and antimicrobial activity using the broth microdilution method. The anti HIV-1 reverse transcriptase activity was determined by the colorimetric MTT method and inhibition of virusinduced cytopathogenicity in MT-4 cells. Results: Compound 4i (50 μM) showed better antifungal activity against A. clavatus. Compound 4g (50 μM) with 95% inhibition demonstrated good activity against M. tuberculosis H37Rv. Compound 4k showed CC50 (50 μM) against MT-4 (CD4+ Human T-cells containing an integrated HTLV-1 genome) cells by 50%, while 16 μM concentration value EC50 from the HIV-1 induced cytopathogenicity. Molecular docking study suggested that 4k interacted with the target with binding energy by Vina score (-10.3 Kcal/mol) Conclusion: The preliminary in vitro evaluation results revealed that some of the compounds have promising antimicrobial activities as well as antitubercular potency. Among the various substituents on benzylidene, the nitro group was the most beneficial for improving the anti-HIV-1 activity. Docking result suggested that 4k compound could be acting as a non-competitive or weak inhibitor of Reverse Transcriptase (RT).

Design, synthesis and evaluation of novel phenyl propionamide derivatives as non-nucleoside hepatitis B virus inhibitors

As an ongoing search for potent non-nucleoside anti-HBV agents with novel structures, we described a series of phenyl propionamide derivatives (3a-b, 4a-e, 7a-g, 8a-h and 9a-b) by pharmacophore fusion strategy in the present work. All the compounds exhibited an anti-HBV activity to some extent. Among them, compounds 8d and 9b displayed most potent anti-HBV activity with IC50 values on HBV DNA replication of 0.46 and 0.14 μM, respectively. And the selective index values of 8d and 9b were more than 217.39 and 153.14, suggesting that 8d and 9b exhibited favorable safety profiles. Interestingly, 8d and 9b possessed significantly antiviral activities against lamivudine and entecavir resistant HBV mutants with IC50 values of 0.77 and 0.32 μM. Notably, preliminary anti-HBV action mechanism studies showed that 8d could inhibit intracellular HBV pgRNA and RT activity of the HBV polymerase. Molecular docking studies suggested that compound 8d could fit into the dimer-dimer interface of HBV core protein by hydrophobic interaction. In addition, in silico prediction of physicochemical properties showed that 8d conformed well to the Lipinski's rule of five, suggesting its potential for use as a drug like molecule. Taken together, 8d possessed significantly anti-HBV activity, low toxicity, diverse anti-HBV mechanism and favorable physicochemical properties, and warranted further investigation as a promising non-nucleoside anti-HBV candidate.

We have developed simple, greener, safer multicomponent synthesis series of 4-arylidene-2-phenyl-5(4H) oxazolones 4(a-r) catalyzed by Bronsted acid ionic liquid as triethylammonium hydrogen sulfate [Et3NH][HSO4] and catalytic amount of acetic anhydride and sodium acetate with excellent yields (90–99%). The protocol offers economical, environmentally benign, solvent-free conditions, and recycle–reuse of the catalyst and easily available starting as benzoyl chloride 1, amino acid 2 and a variety of aldehydes 3. The cyclization followed by condensation of benzoyl chloride, amino acid, and a variety of aldehydes catalyzed by ILs [Et3NH][HSO4] and catalytic amount of acetic anhydride and sodium acetate. The final products were confirmed by their characterization data such as FTIR, 1H-NMR, 13C-NMR, Mass, high-resolution mass spectra and were compared with its reported method.

Microwave-Assisted Erlenmeyer Synthesis of Azlactones Catalyzed by MgO/Al2O3 under Solvent-Free Conditions

MgO/Al2O3 catalyzes the synthesis of azlactone derivatives from condensation reaction of aldehydes (or ketones) with hippuric acid and acetic anhydride as a dehydrating agent under microwave irradiation. The low toxicity, low cost, ease of handling, and high activity of MgO/Al2O3 make this procedure particularly attractive. Also, this catalyst can be easily recovered by decant and can be reused for this condensation five times in succession without considerable loss of its catalytic activity.

An expedient synthesis of oxazolones using a cellulose supported ionic liquid phase catalyst

A novel cellulose supported ionic liquid phase catalyst containing hydroxide ions ([CellFemImi]OH) has been synthesized by covalent anchoring of 1-N-ferrocenylmethyl imidazole in the functionalized cellulose matrix followed by an anion metathesis reaction. The [CellFemImi]OH was characterized by various techniques including FT-IR, FT-Raman, 13C solid state NMR, X-ray diffraction, energy dispersive X-ray (EDX) analysis, field emission scanning electron microscopy (FESEM) and thermogravimetric analysis. The [CellFemImi]OH was effectively employed as a heterogeneous catalyst in the synthesis of oxazolones by cyclocondensation of aryl aldehydes with hippuric acid in the presence of acetic anhydride.
