Notizen: The mass spectroscopic behaviour of the methyl ester of prostaglandins E1 and E2 has been studied with the aid of low eV spectra, measurements on metastable ion decompositions and high resolution mass measurements. Mechanisms are proposed for the formation of the majority of the abundant fragment ions of these biologically important compounds. The mass spectra of free acids are also discussed.

Notizen: The amino acid sequence of a polypeptide can be deduced by an identification of all the dipeptides obtained from a Dipeptidylaminopeptidase I hydrolysate of the original polypeptide and its des N-terminal amino acid derivative. The components of such dipeptide mixtures can be readily identified from the chemical ionization (helium) mass spectra of their N-ethoxycarbonylpropenyl methyl ester derivatives without prior separation. The pyrolytic conversion of N-protected peptide dimethyltrideuteromethyl anilinium salts to their methyl esters in the direct insertion probe of a mass spectrometer was found to be most suitable for the derivatization of such dipeptide mixtures.

Marine sterols. III - the sterol compositions of oceanic jellyfish. The use of gas chromatographic mass spectrometric techniques to identify unresolved componentsAbbreviations: Pelagia spp. = Pel; Atolla spp. = Ato; Periphylla spp. = Per. (1976)

Notizen: The sterol compositions of three oceanic jellyfish have been determined using gas chromatographic mass spectrometric techniques involving the use of two separate gas chromatographic column systems. The components in overlapping peaks have been identified by comparison of the mass spectra of peaks in the two column systems using subtractive techniques. A mid-water animal, Periphylla periphylla, was found to contain a very complex and unusual sterol profile including rare 5α-stanols, whereas two other oceanic jellyfish Pelagia noctiluca and Atolla wyvillei contained similar mixtures of Δ5 sterols to those previously isolated from coastal species.

Thema: Chemie und Pharmazie

Notizen: A general derivatization method has been developed for both primary and secondary aminoalkylphosphonic acids. Derivatization is effected by reaction with trifluoroacetic acid and trifluoroacetic acid anhydride followed by esterification using ethereal diazo-n-butane. This method can be used for microgram quantities and permits ready characterization by both gas chromatography and gas chromatography mass spectrometry. The structure of this derivative has been verified by mass spectrometry and proton magnetic resonance. Fragmentation patterns were confirmed by high resolution mass spectrometry, isotope labeling and the formation of derivative analogs.
