The synthesis and analytical applications of the new heterocyclic ligand are described. The complexation reaction of the ligand with some cations was studied in aqueous methanol at room temperature using the spectrophotometric method. Results revealed that only the absorption spectra of the Fe (III)–ligand complex show a high redshift of the absorption maximum in the aqueous methanol soluti...

The structure of fungal beauveriolide III, an inhibitor of lipid droplet formation in mouse macrophages, was elucidated to be cyclo-[(3S,4S)-3-hydroxy-4-methyloctanoyl-L-phenylalanyl-L-alanyl- D-allo-isoleucyl] by spectral analyses and chemical degradation.

We are sincerely grateful to have been invited by the Guest Editor of this special issue, Prof. Francesca Lisi, to write an article in honor of our mentor Gaetano Aurelio Lanzarone (for students, colleagues and friends simply ‘Elio’). We were the first (Stefania) and last (Federico) of Elio’s students, and we both entertained a particularly deep relation with him. What we want to do here is to ...

The equilibrium reactions of the metallochromic indicator dye Antipyrylazo III with calcium at physiological ionic strength have been investigated spectrophotometrically. Dye absorbance as a function of wavelength was measured at various total dye and calcium concentrations. Analysis of the absorbance spectra indicated that at pH 6.9 at least three calcium:dye complexes form, with 1:1, 1:2, and...
