The photophysical properties are calculated for the dibenzothiophene sulfone substituted with various electron donor moieties:3,7-bis[N,N-di(4-tert-butylphenyl)amino]dibenzothiophene-S,S-dioxide (1L), 2,8-bis[N,N-di(4-tert-butylphenyl)amino]dibenzothiophene-S,S-dioxide (1A), and 2,8-bis[N,N-di(4...

The reactivity of dibenzothiophene (DBT) or dibenzothiophene sulfone (DBTO2) with a variety of phenylboronic acids was mediated by the nickel precursor [Ni(dippe)Cl2] in the presence of a base. The reaction was performed under relatively mild conditions (70–100 °C), in aqueous media. The study...

We reported herein the design, synthesis and biological evaluation of a series of 5-hydroxypyrido[2,3-b]pyrazin-6(5H)-one derivatives as HIV-1 reverse transcriptase (RT) ribonuclease H (RNase H) inhibitors using a privileged structure-guided scaffold refining strategy. In view of the similaritie...

Lead Zirconate Titanate(Pb (Zrx Ti1-x)o3) is one of the perovskite can be used for generating electricity by applying mechanical pressure and also can be used of developing deflection by applying electrical field. Many researchers are employing this material for both the applications because of ...

Inhibition of BET family of bromodomain is an appealing intervention strategy for several cancers and inflammatory diseases. This article highlights our work toward the identification of potent, selective, and efficacious BET inhibitors using a structure-based approach focused on improving poten...

A series of new dithiocarbamates containing a 2(5H)-furanone-piperazine group was synthesized. These compounds show good in vitro cytoxic activity. Among them, compound 6c exhibits the best inhibitory activity against HeLa cell lines with an IC50 of 0.06 ± 0.01 μM for 72 h, and it has good inh...

Our previous work has identified the Pt-Ni/SiO2 bimetallic catalyst as a promising catalyst for the selective hydrogenation of biomass-derived 2(5H)-furanone to γ-butyrolactone (GBL). The competitive relationship between the selective hydrogenation of 2(5H)-furanone over Pt-Ni metal sites and t...

For validating the experimental results researchers use either computational methods or analytical methods. The three methods(experimental, computational and analytical) are based on direct perception, logical inference and past literature work, which are interrelated to each other. Results neve...

The FT-IR and FT-Raman spectra of 1-[(Cyclopropylmethoxy)methyl]-5-ethyl-6-(4-methylbenzyl)-1,2,3,4-tetrahydropyrimidine-2,4-dione were recorded. In this work, experimental and theoretical study on the molecular structure and vibrational wavenumbers of the title compound are presented. The vibra...

When Ph2P(S)NHOCOPh labelled with 18O in the CO group (43% isotopic enrichment) reacts with NaOMe in MeOH, the products are unlabelled Ph2P(O)NH2 and labelled PhCO2Me (43% isotopic enrichment). By implication, the intermediate Ph2P(O)NHSCOPh that results from rearrangement (transposition of O ...

N-(Diphenylphosphinothioyl)hydroxylamine has been prepared from Ph2P(S)Cl using H2NOSiMe3. The derivative Ph2P(S)NHOCOPh rearranges to Ph2P(O)NHSCOPh with base; this transposition of O and S seems to require a 3-membered ring comprising P, S and N atoms.

To address the insufficient ion conductivity of hydroxide exchange membranes (HEMs) used in alkali membrane fuel cells (AMFCs), we present a series of aligned layered double hydroxide (LDH)/polyphenyl ether (PPO) composite membranes based on the electrorheological effect. The hexagonal LDH was f...

Time- and concentration-course studies were conducted to determine the effect of chloro-, methoxy-, and methylthio- substitutions of bis(isopropylamino)-s-triazine on photosynthesis, respiration, RNA synthesis, protein synthesis, and lipid synthesis using isolated leaf cells of Phaseolus vulgari...

Four oxacalix[4]arene derivatives, in which 1,3-dinitrobenzene units and 1,3-di-tert-butylbenzene units are incorporated in alternating order, were synthesized by aromatic nucleophilic substitution. The introduction of the tert-butyl groups increased the stability of the macrocycles against nucl...

A number of benzoic acid analogues showed antifungal activity against strains of Aspergillus flavus, Aspergillus fumigatus and Aspergillus terreus, causative agents of human aspergillosis, in in vitro bioassays. Structure–activity analysis revealed that antifungal activities of benzoic and gall...

Thin film of poly(3-allyl-5-[(4-nitrophenyl)diazenyl]-2-thioxothiazolidine-4-one) (PNPDT) was prepared by thermal deposition technique. Both of the infrared spectra and the atomic force microscopy (AFM) confirmed the polymeric nature of PNPDT thin films. The layered crystalline structure of the ...
