A novel series of proflavine ureas, derivatives 11a–11i, were synthesized on the basis of molecular modeling design studies. The structure of the novel ureas was obtained from the pharmacological model, the parameters of which were determined from

Iron oxides are common minerals that occur in the environment, either naturally or as a result of human activities.The most common Fe(III)-hydroxides and -oxides include ferrihydrite (Fe5HO8 .4H2O) that transforms to hematite (a-Fe2O3 ) and/or goethi

Polycyclic aromatic hydrocarbons (PAHs) are a group of serious contaminants of air, water soil and sediments. Persistence and accumulation of PAHs in the environment is due to their hydrophobicity and hence low solubility and bioavailability to micro

Acid mine drainages (AMDs) arise at the weathering of sulphidic minerals. The occurrence of acidic streams is commonly associated with the human mining activities. Due to the disruption and excavation of sulphide deposits, the oxidation processes hav

A flexible synthetic approach to biologically active sphingoid base-like compounds with a 3-amino-1,2-diol framework was achieved through a [3,3]-sigmatropic rearrangement and late stage olefin cross-metathesis as the key transformations. The stereoc
