A study was conducted to synthesise and evaluate the anti-inflammatory and anti-microbial activities of mannich bases from 1, 2 - hydroxy pyrazolines. For this, vanillin was reacted with substituted acetophenones and different vanillinyl chalcones were obtained which when coupled with phenyl hydrazine, produced hudroxy 1, 2 - pyrazolines. The hydroxyl pyrazolines were reacted with sulpha drugs ...

Auxins are growth regulators involved in virtually all aspects of plant development. However, little is known about how plants synthesize these essential compounds. We propose that the level of indole-3-acetic acid is regulated by the flux of indole-3-acetaldoxime through a cytochrome P450, CYP83B1, to the glucosinolate pathway. A T-DNA insertion in the CYP83B1 gene leads to plants with a pheno...

Thirty-two heterocyclic compounds, including 24 nitroheterocycles, 7 aminoheterocycles and derivatives, and 1 thiophene lacking a nitro group, were tested for mutagenic activity in Salmonella typhimurium TA 98 and TA 100. All the nitroheterocycles (11 new), including nitrofurans, nitrothiophenes, nitropyrroles, and 1 nitroimidazole, were mutagenic in TA 100; 13 were also mutagenic in TA 98. 5-N...

Recent studies suggest that aliphatic b-nitro alcohols may represent a useful class of compounds for use as in vivo therapeutic corneoscleral cross-linking agents with higher order nitroalcohols (HONAs) showing enhanced efficacy over the mono-nitroalcohols. The current study was undertaken in order to evaluate the chemical stability of these compounds during storage conditions. Two mono-nitroal...

Schistosomiasis is a neglected tropical disease that affects millions of people worldwide. Thioredoxin glutathione reductase of Schistosoma mansoni (SmTGR) is a validated drug target that plays a crucial role in the redox homeostasis of the parasite. We report the discovery of new chemical scaffolds against S. mansoni using a combi-QSAR approach followed by virtual screening of a commercial dat...

A new series of N-{4-(6-Chloro-5-nitro-1-[2'--(1H-tetrazol-5-yl)-biphenyl-4-ylmethyl]-1Hbenzoimidazol-2yl-}-phenyl)-3-(substituted-phenyl)-acryl amide derivatives [1-8] has been synthesized and subjected to evaluate their antihypertensive activity. All the synthesized compounds of the series displayed, remarkable activity in comparison to standard drug(losratan ). Many Schiff bases were prepare...

We analyzed water samples from the confluence of three municipal sewage treatment effluent streams, surface water, and whole carp (Cyprinus carpio) for synthetic musks for a period of 7-12 months. The lipid content of each fish was determined and compared with the concentration of musks in the whole fish tissue. Enhanced methods were used for water sampling and musk extraction. The data present...

The metabolism of nitro compounds in plants has not been extensively investigated. Only two such compounds appear to have been reported as occurring naturally in plants. Chloromycetin contains an aromatic nitro group, and occurs in the culture medium of Streptomyces. Certain bacteria (1) and, more recently, a bacterial cell-free enzyme (2) have been shown to bring about the reduction of the nit...

Two salts of the mesoionic compounds 1,4-diphenyl-5-(5-nitro-2-furanyl)-1,3,4-thiadiazolium-2-thiol chloride (MC-1) and 4-phenyl-5-(5-nitro-2-furanyl)-1,3,4-thiadiazolium-2-phenylamine chloride (MC-2) were synthesized utilizing 1,4-diphenyl-thiosemicarbazide and 5-nitro-2-furoyl chloride as starting materials. Their structures were characterized by IR, ¹H-NMR, ¹³C-NMR and elemental analysis. Th...

A dye-sensitized metal-organic framework, TMU-5S, was synthesized based on introducing the laser dye Rhodamine B into the porous framework TMU-5. TMU-5S was investigated as a ratiometric fluorescent sensor for the detection of explosive nitro aromatic compounds and showed four times greater selectivity to picric acid than any state-of-the-art luminescent-based sensor. Moreover, it can selective...
