Mass-spectrometric studies of new 6-nitroquipazines—serotonin transporter inhibitors
Six synthesized 6-nitroquipazine derivatives were examined by electron ionization (EI) and electrospray ionization (ESI) mass spectrometry in positive and negative ion mode. The compounds exhibit high affinity for the serotonin transporter (SERT) and belong to a new class of SERT inhibitors. The EI mass spectra registered in negative ion mode showed prominent molecular ions for all the compound...
متن کاملMass Spectrometric Immunoassays in Characterization of Clinically Significant Proteoforms
Proteins can exist as multiple proteoforms in vivo, as a result of alternative splicing and single-nucleotide polymorphisms (SNPs), as well as posttranslational processing. To address their clinical significance in a context of diagnostic information, proteoforms require a more in-depth analysis. Mass spectrometric immunoassays (MSIA) have been devised for studying structural diversity in human...
متن کاملCharacterization of hemoglobin lepore variants by advanced mass-spectrometric procedures.
We describe an analytical protocol for characterizing the molecular structure of hemoglobin (Hb) Lepore variants by using two different mass-spectrometric approaches. The first method consists of direct examination of the chromatographically separated hybrid globins by electro-spray mass spectrometry; the variant Lepore globin is identified through the accurate determination of its molecular ma...
متن کاملMass spectrometric characterization of oligomers in Pseudomonas aeruginosa azurin solutions.
We have employed laser-induced liquid bead ion desorption mass spectroscopy (LILBID MS) to study the solution behavior of Pseudomonas aeruginosa azurin as well as two mutants and corresponding Re-labeled derivatives containing a Re(CO)(3)(4,7-dimethyl-1,10-phenanthroline)(+) chromophore appended to a surface histidine. LILBID spectra show broad oligomer distributions whose particular patterns d...
متن کاملMass spectrometric investigation of high-mass species in the downstream region of Ar/CF4/O2 plasmas and their formation mechanisms
The mass analysis of positive ions and neutral species was conducted in the downstream region of Ar/CF4/O2 plasmas. The neutral species were ionized by the attachment of Li before mass-analyzing. This ionization method is fragment-free, quite useful for the identification of neutral species contained in the plasmas. CnF2n+1O (n = 2, 3) and CnF2n−1O (1 ≤ n ≤ 7) positive ions and CnF2nO (1 ≤ n ≤ ...
