Latest News on Deacetylase : Feb 2022
The Human Histone Deacetylase Family Since the identification of the first histone deacetylase (Taunton et al., Science 272, 408–411), several new members have been isolated. They can loosely be separated into entities on the basis of their similarity to various yeast histone deacetylases. The first class is represented by its closeness to the yeast Rpd3-like […]
Latest News on Borosilicate : Jan 2022
Borosilicate Glasses Various anomalous properties of borosilicate glasses are explained by the assumption that the atomic groups, each of which consists of one BO4 tetrahedron with four BO3 triangles bonded to it, are formed in these glasses. These atomic groups result from the reasonable postulate that BO4 tetrahedra cannot be bonded to each other, and […]
Latest News on dimethyl : Jan 2022
The Chemistry of Dimethyl Carbonate Dimethyl carbonate (DMC) is a versatile compound that represents an attractive eco-friendly alternative to both methyl halides (or dimethyl sulfate) and phosgene for methylation and carbonylation processes, respectively. In fact, the reactivity of DMC is tunable: at T = 90 °C, methoxycarbonylations take place, whereas at higher reaction temperatures, methylation […]
Latest News on chemical composition : Jan 2022
The Chemical Composition of the Sun The solar chemical composition is an important ingredient in our understanding of the formation, structure, and evolution of both the Sun and our Solar System. Furthermore, it is an essential reference standard against which the elemental contents of other astronomical objects are compared. In this review, we evaluate the […]
Latest News on Mild Steel: September 2021
The adsorption of thiourea on mild steel The adsorption behaviour of thiourea on mild steel was investigated in 1 N H2SO4 over the temperature range 20–50°C in the region of high coverage. The process was treated as a substitutional adsorption process. Particular attention was paid to the effect of the lateral interaction and the […]
Chemistry of Organic Compounds in the Beer Production: Second Edition
Beer can be thought of as a diluted ethanol solution containing a variety of organic compounds. These organic molecules are subjected to a range of chemical reactions that occur during fermentation, storage, and finally determine the beer’s unique ageing as well as its quality.

Latest News on Combretaceae: March – 2020
Biological activity of five antibacterial flavonoids from Combretum erythrophyllum (Combretaceae) Preliminary studies with Combretum erythrophyllum showed antimicrobial activity against Gram-positive and Gram-negative bacteria. Seven antibacterial flavonoids were subsequently isolated by bioassay-guided fractionation, i.e. apigenin; genkwanin; 5-hydroxy-7,4′-dimethoxyflavone, rhamnocitrin; kaempferol; quercetin-5,3′-dimethylether; rhamnazin. All compounds had good activity against Vibrio cholerae and Enterococcus faecalis, with MIC values in the range of 25–50 μg/ml. Rhamnocitrin and quercetin-5,3′-dimethylether […]
