A novel type of stimuli-responsive fluorescent polymers has been developed via the self-assembly of riboflavin-5′-phosphate (RiP) as ligand and europium (III) (Eu3+) as central metal ion coordinated with the ligand. The as-prepared RiP/Eu3+ coordination polymers (RiP/Eu3+ CPs) are smart and mul...
Experimental determination of mass densities and interfacial tensions (IFT) at liquid-liquid equilibrium (LLE) for methyl ester (FAME) demixed aqueous family (from methyl formate to methyl heptanoate) are reported as a function of temperature at atmospheric pressure (101.3 kPa). Mass density det...
Carbon capture, utilization and sequestration technology is effective for carbon emissions reduction. The development of new absorbent seems to be one of the core components of carbon capture technology. In this paper, three esters, methyl heptanoate, ethyl hexanoate and methyl benzoate, were se...
The experimental measurements for liquid viscosities of four fatty acid methyl esters, including methyl hexanoate, methyl heptanoate, methyl caprylate, and methyl nonanoate, were carried out with a falling-cylinder viscometer. For the present measurement, the temperature ranges were from 292 K t...
A series of novel, potent and selective human β2 adrenoceptor agonists incorporating a urea moiety on the terminal right-hand side phenyl ring of (R)-salmeterol is presented. Urea 9j had long duration of action in vitro on guinea pig trachea, and also in vivo similar to that of salmeterol. It h...
The treatment of tuberculosis is becoming more difficult due to the ever increasing prevalence of drug resistance. Thus, it is imperative that novel anti-tuberculosis agents, with unique mechanisms of action, be discovered and developed. The direct anti-tubercular testing of a small compound lib...
p38α mitogen activated protein kinase (MAPK) inhibitors provide a novel approach for the treatment of inflammatory disorders. A series of fifteen pyrazolyl urea derivatives (3ao) were synthesized and evaluated for their p38α MAPK inhibition and antioxidant potential. Compounds 3ae, 3g and 3h s...
A series of novel biphenyl urea derivates were synthesized and investigated for their potential to inhibit vascular endothelial growth factor receptor-2 (VEGFR-2). In particular, A7, B3 and B4 displayed significant enzymatic inhibitory activities, with IC50 values of 4.06, 4.55 and 5.26 nM. Comp...
Urease is an enzyme of amidohydrolase family and is responsible for the different pathological conditions in the human body including peptic ulcers, catheter encrustation, kidney stone formation, hepatic coma, encephalopathy, and many others. Therefore, the search for potent urease inhibitors ha...
The current study deals with the synthesis of urea and thiourea derivatives 1–37 which were characterized by various spectroscopic techniques including FAB-MS, 1H-, and 13C NMR. The synthetic compounds were subjected to urease inhibitory activity and compounds exhibited good to moderate urease ...
Twenty-six compounds derived from 3′-aminocombretastatin A-4 (AmCA-4) containing a urea fragment mimicking the structure of Sorafenib, have been synthesized and evaluated as antiangiogenic compounds. Antiproliferative activity of all the synthetic ureas has been measured on tumor cell lines HT-...
The crystal structure and spectroscopic properties of (3aR,6S,7aR)-7a-bromo-6-methyl-2-[(4-methylphenyl)sulfonyl]-1,2,3,6,7,7a-hexahydro-3a,6-epoxyisoindole were determined by X-ray diffraction, IR and 13CNMR and 1H NMR spectroscopy techniques. We investigate molecular and crystal structure of t...
Alkaline phytases from Bacillus species, which hydrolyze phytate to less phosphorylated myo-inositols and inorganic phosphate, have great potential as additives to animal feed. The thermostability and neutral optimum pH of Bacillus phytase are attributed largely to the presence of calcium ions. ...
Bacterial wilt, caused by Erwinia tracheiphila (Smith), can result in serious yield loss of cantaloupe in the Midwest United States. Although neonicotinoid insecticides are an effective means of managing the cucumber beetles that vector E. tracheiphila, this management regime may cause toxicity ...
Cellular energy is closely related to fruit ripening, senescence, physiological disorder and disease resistance after harvest. Nanguo pear fruit were immersed in 100 mg L−1 Acibenzolar-S-methyl (ASM) for 10 min, then air-dried at ambient conditions and stored for 12 d at 20 °C to investigate th...
Orchard experiments on integration of acibenzolar-S-methyl (ASM) with antibiotics for protection of pear and apple from fire blight were conducted in the west coast region of the United States over a period of 5 years. In 11 pathogen-inoculated trials, a single treatment of streptomycin or oxyte...
Apple fruit were treated with 100 mg L−1 acibenzolar-S-methyl (ASM) and 100 μM dehydroepiandrosterone (DHEA) to investigate its effect on the lesion development inoculated with Penicillium expansum. Effects of ASM on the glucose-6-phosphate dehydrogenase (G6PDH) activity, nicotinamide ademine d...
Blueberry fruits were immersed in 100 mg/L acibenzolar-S-methyl (ASM) for 10 min and then stored at 4 °C with 40–50% relative humidity (RH) to investigate the changes of anti-oxidative enzyme activity, antioxidants and secondary metabolites in reactive oxygen species metabolism and phenylpropa...
An irrefutable advancement has been noted for the infectious diseases caused due to ureolytic bacteria through the development of various drugs. Keeping in mind the extremely valuable synthetic utility and medicinal significance of thiourea derivatives, synthesis of new 3-trifluoromethyl benzoic...
Thermally unstable (3,3,3-trifluoroprop-1-en-2-yl)lithium was generated by lithiation of 2-bromo-3,3,3-trifluoroprop-1-ene and successively underwent borylation in a flow microreactor system. Direct use of the 1-(trifluoromethyl)vinylborate thus formed for the Suzuki–Miyaura coupling in a batch...
