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 ...

Background & Aims: Angiogenesis plays an important role in tumor growth and metastasis of cancer; therefore, compounds that inhibit the angiogenesis process can prevent tumor growth. Recently, Schiff base complexes have become important due to properties such as anticancer, anti-oxidant, and the like. In this study, the angiogenesis effect of the copper Schiff base complex on the chorioallantoi...

AIM The cooper(II) complex combination of N, N'-disalicylidenemethylenediamine and the Schiff bis base were investigated for anti-inflammatory activity. MATERIAL AND METHODS In vivo, the anti-inflammatory activity of the metallic complex in comparison with the activity of the Schiff bis base was tested by the method of Winter and co-workers using the Levy technique. RESULTS AND DISCUSSIONS ...

The asymmetric unit of the title compound, C(22)H(28)N(2)O(3)·CH(4)O, consists of two independent Schiff base mol-ecules and two independent methanol solvent mol-ecules. In one Schiff base mol-ecule, the 2-hydr-oxy group forms an intra-molecular hydrogen bond with the amide O atom, whereas in the other Schiff base mol-ecule, the 2-hydr-oxy-substituted benzene ring is oriented so that the 2-hydr...
