So3h-functionalized zeolite-y as an efficient nanocatalyst for the synthesis of n-benzimidazole-2-aryl-4-thiazolidinones and tri-substituted imidazoles

Background: SO3H-functionalized zeolite-Y was prepared and used as a catalyst for the synthesis of 2-aryl-N-benzimidazole-4-thiazolidinones and tri-substituted imidazoles at ambient conditions. Objective: The goals of this catalytic method include excellent yields and high purity, inexpensive procedure and ease of product isolation, the use of nontoxic and heterogeneous acid catalyst, shorter reaction times and milder conditions. Materials and Methods: NMR spectra were recorded on Brucker spectrophotometer using Me4Si as internal standard. Mass spectra were recorded on an Agilent Technology 5975C VL MSD with tripe-axis detector. FT-IR spectra were obtained with KBr disc on a galaxy series FT-IR 5000 spectrometer. The surface morphology of nanostructures was analyzed by FE-SEM (EVO LS 10, Zeiss, Carl Zeiss, Germany). BET analysis were measured at 196 C by a Japan Belsorb II system after the samples were vacuum dried at 150C overnight. Results: The NSZ was characterized by FT-IR, FESEM, EDX, XRF, and BET. The catalytic activity of NSZ was investigated for synthesis of 1,3-tiazolidin-4-ones in H2O/Acetone at room temperature. Moreover, NSZ was used for synthesis of tri-substituted imidazoles at 60 C via solvent-free condensation. Different kinds of aromatic aldehydes were converted to the corresponding of products with good to excellent yields. Conclusion: Sulfonated zeolite-Y was as an efficient catalyst for the preparation of N-benzimidazole-2-aryl-1,3-thiazolidin-4-ones and 2,4,5-triaryl-1H-imidazoles. High reaction rates, elimination toxic solvent, simple experimental procedure and reusability of the catalyst are the important features of this protocol.

Synthesis, characterization and antimicrobial screening of some novel 5-(benzofuran-2-yl)-N?-(2-substituted-4-oxothiazolidin-3-YL)-1-phenyl-1hpyrazole- 3-carboxamide derivatives

A series of innovative 5-(benzofuran-2-yl)-N?-(2-substituted-4-oxothiazolidin-3-yl)-1-phenyl-1H-pyrazole-3- carboxamide (4a-i) derivatives were synthesized by cyclocondensation reaction of various carbohydrazones (3a-i) with thioglycolic acid in DMF. The intermediate N?-(benzylidene)-5-(benzofuran-2-yl)-1- phenyl-1H-pyrazole-3-carbohydrazides (3a-i) was obtained by condensation of 5-(benzofuran-2-yl)-1-phenyl-1Hpyrazole- 3-carbohydrazide (1) with various substituted aromatic aldehydes (2a-i) in ethanol. The structures of newly synthesized compounds (4a-i) were corroborated through elemental analysis and spectral studies like IR, 1H NMR, 13C NMR and Mass spectra. The compounds were screened for their in-vitro antibacterial activity against a panel of pathogenic microorganism including gram-negative strains E. coli, P. vulgaris and S. typhi and grampositive bacterial strain, S. aureus at diverse concentrations and the result of bioassay was compared with Chloramphenicol.

Achiral counterion control of enantioselectivity in a Bronsted acid-catalyzed lactonization

Highly enantioselective halolactonizations have been developed that employ a chiral proton catalyst-N-iodosuccinimide (NIS) reagent system in which the Bronsted acid is used at catalyst loadings as low as 1 mol %. An approach that modulates the achiral counterion (equimolar to the neutral chiral ligand-proton complex present at low catalyst loadings) to optimize the enantioselection is documented for the first time in this transformation. In this way, unsaturated carboxylic acids are converted to gamma-lactones in high yields (up to 98% ee) using commercially available NIS.

Discovery of Piperazinylquinoline Derivatives as Novel Respiratory Syncytial Virus Fusion Inhibitors

A novel series of piperazinylquinoline derivatives were discovered as respiratory syncytial virus (RSV) fusion inhibitors by the ligand-based screening approach. Among 3,000 hits, 1-amino-3-[[2-(4-phenyl-1-piperidyl)-4-quinolyl]amino]propan-2-ol (7) was proven to be active against the RSV long (A) strain. The anti-RSV activity was improved by converting piperidine to benzylcarbonyl substituted piperazine. The basic side chain was also found to be crucial for anti-RSV activity. The selected analogues, 45 and 50, demonstrated anti-RSV activities up to EC50 = 0.028 muM and 0.033 muM, respectively. A direct anti-RSV effect was confirmed by a plaque reduction assay and a fusion inhibition assay. Both 45 and 50 showed promising DMPK properties with good oral bioavailability, and could potentially lead to novel therapeutic agents targeting the RSV fusion process.

Synthesis, characterization, biological evaluation and molecular docking studies of 2-(1H-benzo[d]imidazol-2-ylthio)-N-(substituted 4-oxothiazolidin-3-yl) acetamides

Background: A series of 2-(1H-benzo[d]imidazol-2-ylthio)-N-(substituted 4-oxothiazolidin-3-yl) acetamides was synthesized and characterized by physicochemical and spectral means. The synthesized compounds were evaluated for their in vitro antimicrobial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Candida albicans and Aspergillus niger by tube dilution method. The in vitro cytotoxicity study of the compounds was carried out against human colorectal (HCT116) cell line. The most promising anticancer derivatives (5l, 5k, 5i and 5p) were further docked to study their binding efficacy to the active site of the cyclin-dependent kinase-8. Results: All the compounds possessed significant antimicrobial activity with MIC in the range of 0.007 and 0.061 muM/ml. The cytotoxicity study revealed that almost all the derivatives were potent in inhibiting the growth of HCT116 cell line in comparison to the standard drug 5-fluorouracil. Compounds 5l and 5k (IC50 = 0.00005 and 0.00012 muM/ml, respectively) were highly cytotoxic towards HCT116 cell line in comparison to 5-fluorouracil (IC50 = 0.00615 muM/ml) taken as standard drug. Conclusion: The molecular docking studies of potent anticancer compounds 5l, 5k, 5i and 5p showed their putative binding mode and significant interactions with cyclin-dependent kinase-8 as prospective agents for treating colon cancer.

An update on chemical classes targeting ERK1/2 for the management of cancer

Cancer, still in the limelight due to its dreadful nature, shows overexpression of multiple signaling macromolecules leading to failure of many chemotherapeutic agents and acquired resistance to chemotherapy. These factors highlight the significance of shifting toward targeted therapy in cancer research. Recently, ERKs (ERK1 and 2) have been established as a promising target for the management of various types of solid tumors, due to their aberrant involvement in cell growth and progression. Several ERKs inhibitors have reached clinical trials for the management of cancer and their derivatives are being continuously reported with noteworthy anticancer effect. This review highlights the recent reports on various chemical classes involved in the development of ERKs inhibitors along with their in vitro and in vivo activity and structure-activity relationship profile.

Organic selenium compounds as potential chemotherapeutic agents for improved cancer treatment

Selenium(Se)-containing compounds have attracted a growing interest as anticancer agents over recent decades, with mounting reports demonstrating their high efficacy and selectivity against cancer cells. Typically, Se compounds exert their cytotoxic effects by acting as pro-oxidants that alter cellular redox homeostasis. However, the precise intracellular targets, signalling pathways affected and mechanisms of cell death engaged following treatment vary with the chemical properties of the selenocompound and its metabolites, as well as the cancer model that is used. Naturally occurring organic Se compounds, besides encompassing a significant antitumor activity with an apparent ability to prevent metastasis, also seem to have fewer side effects and less systemic effects as reported for many inorganic Se compounds. On this basis, many novel organoselenium compounds have also been synthesized and examined as potential chemotherapeutic agents. This review aims to summarize the most well studied natural and synthetic organoselenium compounds and provide the most recent developments in our understanding of the molecular mechanisms that underlie their potential anticancer effects.
