Two biologically active Schiff bases, C13H10BrON (4), C13H9Br2O2N (5), were synthesized by the reaction of 2-aminophenol (1) with 3-bromobenzaldehyde (2) or 3,5-dibromo-4hydroxybenzaldehyde (3) in the presence of conc. H2SO4. The characterization of Schiff bases were carried out by using spectroscopic techniques including IR, H-NMR, FAB-MS along with elemental analyses. The Schiff bases were ch...
Schiff base denotes a reaction product of a primary amine and a carbonyl compound. Schiff bases possess a wide variety of biological activity specially antibacterial and antifungal properties. Metal complexes of Schiff base have been studied for their biological activities. This review articles provide a summary of medicinal chemistry features of Schiff base and various reports published on bio...
Addition of Potassium cyanide to a mixture of Schiff base and lithium perchlorate afforded a-aminonitriles in high yields. Addition of potassium cyanide to a methanolic solution of Schiff base and phosphoric acid afforded a-aminonitriles. When the reaction mixture was refluxed it gave a-amino acids in high yields.
A new class of rhodopsins covalently linked to an enzymatic domain was discovered recently. A member of this class of enzymerhodopsins, the rhodopsin-guanylyl cyclase (RhGC) was identified in the aquatic fungus Blastocladiella emersonii (BE). Characterization of RhGC showed that the second-messenger molecule cGMP (cyclic guanylyl monophosphate) is produced upon green light illumination. Here, t...
A Schiff base was prepared from the interaction of ethanolic solutions of 2-hydroxy-1– naphthaldehyde and butylenediamine. The complexes were synthesized by refluxing the mixture of ethanolic solutions of the Schiff base and respective metal (II) chloride. Their solubility, melting point/decomposition temperature, molar conductance, elemental analysis and IR were carried out. The melting point ...
