Aromaticity and relative stabilities of azines.
The most refined nucleus-independent chemical shift index (NICS(0)(πzz)) and the extra cyclic resonance energies (ECREs), based on the block localized wave function (BLW) method, show that the aromaticity of all azines is like that of benzene. The same is true for aza-naphthalenes relative to naphthalene. The lower relative energies of isomers with vicinal N's are due to the weakness of NN bond...
متن کاملAzines as histamine H4 receptor antagonists.
Since 2000, when the histamine H4 receptor (H4R) was cloned, it has constituted an interesting target for drug development. Pharmacological studies suggest the potential utility of histamine H4R antagonists/inverse agonists in the treatment of inflammatory diseases, e.g. allergic rhinitis, asthma, atopic dermatitis, colitis, or pruritus. The first H4R ligands were non-selective compounds, but i...
متن کاملRemoval of Cysteine (an Aliphatic Amino Acid) by Natural Clinoptilolite
Amino acids have been extensively used in several processes of the pharmaceutical and food industries. Treatments for the recovery and reuse of the wastewaters generated from these processes are few and little known. This work aims at studying the influence of different variables on the sorption of L-cysteine, contained in aqueous solutions, on clinoptilolite mineral. L-Cysteine (Cys) was s...
متن کاملPyrolysis and catalytic pyrolysis of protein- and lipid-rich feedstock
In this study, pyrolysis of microalgal remnants was investigated for recovery of energy and nutrients. Chlorella vulgaris (C.vulgaris) biomass was first solvent-extracted for lipid recovery then the remnants were used as the feedstock for fast pyrolysis experiments using a fluidized bed reactor at 500 o C. Yields of bio-oil, biochar and gas were 53, 31, and 10wt.%, respectively. Bio-oil from C....
متن کاملMolecular products from the pyrolysis and oxidative pyrolysis of tyrosine.
The thermal degradation of tyrosine at a residence time of 0.2s was conducted in a tubular flow reactor in flowing N2 and 4% O2 in N2 for a total pyrolysis time of 3min. The fractional pyrolysis technique, in which the same sample was heated continuously at each pyrolysis temperature, was applied. Thermal decomposition of tyrosine between 350 and 550°C yielded predominantly phenolic compounds (...
