An exploration we carried out for isolating nitric oxide (NO) inhibitors from the rhizomes of Curcuma phaeocaulis afforded one new salvialane-type sesquiterpene, phasalvione (1), two novel nor-sesquiterpenes, phaeocaudione (2) and phaeocauone (3), one aromatic acid 3-methyl-4-(3-oxo-butyl)-benzoic acid (4), two γ-elemene-type sesquiterpenes, 8β(H)-elema-1,3,7(11)-trien-8,12-lactam (5) and 8β-me...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
Zingiber species are members of the Zingiberaceae family, and are widely used for medicinal and food purposes. In this study aboveground and root parts of Zingiber mioga and Zingiber officinale were subjected to metabolite profiling by ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS) and gas chromatography time-of-flight mass spectrometry (GC-T...
Arene diazonium tetrafluoroborates can be synthesized from aromatic acetamides via a sequence of deacetylation, diazotation and precipitation, induced by anion exchange. The reaction is conducted as a convenient one-flask transformation with consecutive addition of the appropriate reagents. Exchange of solvents or removal of byproducts prior to isolation of the product is not required. The aren...
Alzheimer’s disease (AD) is a severe neurodegenerative disorder characterized by β-amyloid (Aβ) plaques, neurofibrillary tangles, neuronal death, progressive cognitive impairment and memory loss. β-amyloid peptides (Aβ) are major compositions of so-called senile plaques, which are hallmarks of AD and contribute to AD progression. Therefore, it is important to discover therapeutics against Aβ-in...
