Abstract
SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL STUDY OF NOVEL LNIII-15C5/B15C5 COMPLEXES

Rajeev Ranjan*, Poonam Bhardwaj and Seema Chitlangia

ABSTRACT

Crown ethers have many applications in catalysis, organic synthesis, biochemistry, microbiology, and material science. Their applications in biology include the ability to regulate enzyme activity, interaction with DNA, and as antimicrobial agents. Simple crown compounds have the ability to interact with enzymes. The crown ethers are excellent hosts for accommodating metal ions via ion-dipole interaction. Crown ethers have a lower coordination power towards lanthanides but they have selectivity to the best-fit metal ions. The present paper describes preparation, characterization and antimicrobial study of some novel lanthanide-crown ether complexes with 1,4,7,10,13-pentaoxacyclopentadecane(15C5) and benzo-1,4,7,10,13-1,4,7,10,13-pentaoxacyclopentadecane (b15C5) having general formula of [Ln.L.(Pic)3].3H2O, where Ln3+ = Pr3+/Nd3+, L = 15C5/b15C5 and Pic- = Picrate anion.

Keywords: Simple crown compounds have the ability to interact with enzymes.
