We previously showed by using mass spectrometry that endothelin A selective receptor antagonists BQ123 and JKC301 form novel coordination compounds with sodium ions. This property may underlie the ability of an ETA antagonist to induce net tubular so

Evidence from collisionally activated decomposition (CAD) of electrospray-produced ions in an ion trap shows that lithium ion binds to the backbone ester oxygen atoms of valinomycin to open the cyclodepsipeptide ring at the D-α-hydroxyvaleric acid a

A nomenclature system for labeling fragment ions of cyclic peptides is proposed. A fragment ion is labeled with a four-part descriptor of the general formula xnJZ, where x is the designation for the ion (e.g., lower case a or b, as are used for pepti

A strategy is presented for the determination of amino-acid sequences of cyclodepsipeptide antibiotics. A highly specific sodium-ion interaction with the backbone lactone opens the depsipeptide ring to form a linear acylium ion or isomeric equivalent

Background Oxidoreductases are enzymes that catalyze many redox reactions in normal and neoplastic cells. Their actions include catalysis of the transformation of free, neutral oxygen gas into oxygen free radicals, superoxide, hydroperoxide, singlet

The formation of multiple molecular ions, especially due to sodium adduct ion formation, is commonly observed in electrospray mass spectrometry and may make reproducible and sensitive quantitation difficult. The objective of this work was to investig

Collisionally activated decomposition (CAD) of a protonated cyclic peptide produces a superposition spectrum consisting of fragments produced following random ring opening of the cyclic peptide to give a set of acylium ions (or isomeric equivalents)

Electrospray ionization and fast atom bombardment mass spectrometric methods reveal novel interactions of endothelin A selective receptor antagonists, cyclo(D-Trp-D-Asp-Pro-D-Val-Leu), cyclo(D-Trp-D-Glu-Ala-D-allo-Ile-Leu) and cyclo(D-Trp-D-Asp-Pro-D
