چکیده

great physiological and biological activities which is further exemplified by their roles as anticoagulants (dicoumarols/ warfarins), aflatoxins and psoaralens, the important drugs in use. Apart from the above, their role as caging agents in photoactivable “caged” analogues of biomolecules, cytidine diphosphate and glutamic acid, and as probes for reactive oxygen species (ROS) spurred further interest in these compounds. Earlier studies from our laboratory on biological activity of coumarins and their complexes, showed significant enhancement of antibacterial and antifungal activity of the coumarin derivative on complexation. Keeping this in mind, and in continuation of our previous studies, in the present contribution we report the synthesis and characterisation of Ln(III) complexes with a potentially quadridentate ligand, 3-acetylcoumarin-o-aminobenzoylhydrazone (ACAB) and effect of complexation on biological activity of this ligand.

tion, stable radicals have the advantage that their concentrations are readily and directly measurable. Among them a stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) was investigated as a reactive hydrogen acceptor and further found to be useful for the antioxidant determination. Since then DPPH has been mainly used to examine radical scavenging activity of antioxidative vitamins and po...

derivatives (Fig. 1) that showed in vitro and in vivo antitumor activity. These compounds were also found to inhibit tubulin polymerization as a mechanism of their action in cells. To investigate the possibilities for modification of this scaffold, we divided the moieties into five parts from A to E as shown in Fig. 1. So far, it has been reported that the length of the three carbon chain on mo...

The size distribution of new vesicles formed after addition of oleate in different forms to preformed egg yolk phosphatidylcholine (EggPC) vesicles was studied by gel exclusion chromatography. The addition of oleate to preformed vesicles resulted in the formation of new small vesicles. Fission of preformed vesicles incorporated by oleate and partial solubilization of the vesicles by addition of...
