Background: Benzoxazole-containing ligands find many applications both in medicinal chemistry, catalysis and fluorescence chemosensing. macrocycles could be therefore a good strategy to achieve stable selective fluorescent complexes with suitable metal ions. In this work, the synthesis, binding, photochemical properties of new ligand (L) are reported. L is cyclophane macrocycle containing 1,3-b...

Streptomyces chartreusis NRRL 3881 produces the divalent cation ionophore antibiotic A231871). This antibiotic is primarily active against Grampositive bacteria and fungi and has been used extensively to investigate the role of divalent cations in regulating cellular physiological processes2,3,4). The chemical structure of A231875.6) indicates that it is a member of a new class of ionophorous a...
