Differences in binding kinetics, bond strength and adduct formation between Pt-based drugs and S- or N-donor groups: A comparative study using mass spectrometry techniques. Eur J Pharm Sci 2019; 132:96-105. [PMID: 30844436 DOI: 10.1016/j.ejps.2019.03.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2018] [Revised: 02/26/2019] [Accepted: 03/02/2019] [Indexed: 10/27/2022]
Abstract
Pt-S and Pt-N interactions resulting from the coordination of cisplatin, oxaliplatin and carboplatin to two synthetic peptides that differ from each other in one amino acid (Met or His) have been thoroughly studied in this work. The degree of Pt-binding was determined by inductively coupled plasma mass spectrometry after the separation of the Pt-complexes from the unreacted drugs by size exclusion chromatography. Cisplatin and oxaliplatin showed high affinity for the peptides from the first hours of incubation, although the peptides required longer incubation times to obtain the same platination degrees with cisplatin than with oxaliplatin. Once the reactions reached their maximum binding degrees, the complexes with oxaliplatin began to dissociate, revealing binding reversibility, while a pseudo steady-state was observed for cisplatin until the last day of incubation. Conversely, the equilibrium was not reached for carboplatin and the His-peptide after 30 days, showing a binding degree of 16%, versus 78% for the Met-peptide. The S-donor group also presented an important influence on the reactivity and the adduct formation. The reaction rate for the Met-peptide was faster than the hydrolysis of oxaliplatin and carboplatin, and all the drugs, except oxaliplatin, were able to coordinate up to 3 different donor groups, which were identified by nanospray mass spectrometry. Since structural characterization of metal-complexes often represents an analytical challenge during electrophoretic separations, the strength of Pt-Met and Pt-His bonds was also evaluated under these conditions. The nature of the electrophoretic agents and the incubation times used were the parameters that most affected the stability. Higher Pt losses were found for the Met-peptide (35-90%) than for the His-peptide (16-48%), indicating that Pt-Met bonds were kinetically preferred while Pt-His interactions were thermodynamically favored.

Abstract
The role of trace elements bound to proteins in the etiology and pathogenesis of rheumatoid arthritis (RA) remains unclear. In this sense, the identification and detection of metalloproteins has a strong and growing interest. Metalloprotein studies are currently carried out by polyacrylamide gel electrophoresis (PAGE) associated to inductively coupled plasma mass spectrometry (ICPMS), and despite that complete information can be obtained for metals such as Fe, Cu and Zn, difficulties due to poor sensitivity for other trace elements such as Sn, As, etc, are currently faced. In the present work, a simple and fast method for the determination of trace metals bound to synovial fluid (SF) proteins was optimized. Proteins from SF (long and short-term RA) were separated in ten fractions by native PAGE, then dissolved in nitric acid and peroxide hydrogen, and analyzed by ICPMS. Fifteen metals were determined in each separated protein fraction (band). Adequate calibration of proteins molecular weight allowed stablishing which protein type were bound to different metals.

Abstract
The analysis of the complexes between metal-based chemotherapeutic drugs and proteins in biological samples, such as cisplatin or oxaliplatin, can be a challenge due to metal strong reactivity towards S-donor molecules such as dithiothreitol (DTT) or β-mercaptoethanol (BME), usually employed as reducing agents in electrophoretic separations and proteolytic digestions for LC-MS/MS analysis.•This protocol describes the use of the thiol-free reducing trialkylphosphines, such as tributylphosphine (TBP) and tris(2-carboxyethyl)phosphine (TCEP) as suitable reagents for the preservation of the metal-protein complexes during OFFGEL-IEF and SDS-PAGE separations, respectively.•Moreover, the filter-aided sample preparation (FASP) method is presented as an advantageous option to perform tryptic in-solution digestions of metal-protein complexes in combination with OFFGEL-IEF separations.•The FASP procedure allows including previous reduction and alkylation steps in addition to proteolysis, ensuring the preservation of the metal-protein complexes. The limited time that proteins remain in contact with the reducing agent, either TBP or even DTT, during FASP could be a key factor for its extraordinary performance on the digestion of metal-protein complexes.
