Abstract
![]()
In this paper, several
experimental techniques [X-ray diffraction,
differential scanning calorimetry (DSC), thermogravimetry, Fourier
transform infrared spectroscopy, and broad-band dielectric spectroscopy]
have been applied to characterize the structural and thermal properties,
H-bonding pattern, and molecular dynamics of amorphous bosentan (BOS)
obtained by vitrification and cryomilling of the monohydrate crystalline
form of this drug. Samples prepared by these two methods were found
to be similar with regard to their internal structure, H-bonding scheme,
and structural (α) dynamics in the supercooled liquid state.
However, based on the analysis of α-relaxation times (dielectric
measurements) predicted for temperatures below the glass-transition
temperature (Tg), as well as DSC thermograms,
it was concluded that the cryoground sample is more aged (and probably
more physically stable) compared to the vitrified one. Interestingly,
such differences in physical properties turned out to be reflected
in the lower intrinsic dissolution rate of BOS obtained by cryomilling
(in the first 15 min of dissolution test) in comparison to the vitrified
drug. Furthermore, we showed that cryogrinding of the crystalline
BOS monohydrate leads to the formation of a nearly anhydrous amorphous
sample. This finding, different from that reported by Megarry et al.
[Carbohydr. Res.2011, 346, 1061−106421492830] for trehalose (TRE), was revealed on the
basis of infrared and thermal measurements. Finally, two various hypotheses
explaining water removal upon cryomilling have been discussed in the
manuscript.

Tukra R, Gardner S, Topp EM. Effects of temperature and relative humidity in D 2O on solid-state hydrogen deuterium exchange mass spectrometry (ssHDX-MS). Int J Pharm 2021; 596:120263. [PMID: 33486024 DOI: 10.1016/j.ijpharm.2021.120263] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 01/07/2021] [Accepted: 01/10/2021] [Indexed: 11/15/2022]
Abstract
Lyophilized powders containing myoglobin and various excipients were subjected to ssHDX-MS at different temperatures and D2O vapor activity (RH). Deuterium incorporation was fitted to a bi-exponential association model for each formulation and the dependence of regression parameters on temperature and RH was evaluated. Data fitted best to a simplified model in which the slow exponential term was considered invariant with temperature and RH while the fast exponential term retained its temperature and RH dependence. This suggests that rapid rate processes such as water vapor sorption and initial deuterium labeling may be more dependent on temperature and RH than slower processes such as sequential exchange and transport in the solid matrix.

Evaluation of Predictors of Protein Relative Stability Obtained by Solid-State Hydrogen/Deuterium Exchange Monitored by FTIR. Pharm Res 2020; 37:168. [PMID: 32794130 DOI: 10.1007/s11095-020-02897-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Accepted: 07/28/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE Hydrogen/deuterium (H/D) exchange over a range of temperatures suggests a protein structural/mobility transition in the solid state below the system glass transition temperature (Tg). The purpose of this study was to determine whether solid-state protein stability correlates with the difference between storage temperature and apparent Td where an abrupt change in mobility occurs, or alternatively, the extent of H/D exchange at a single temperature correlates directly to protein stability in lyophilized solids. METHODS Solid-state H/D exchange was monitored by FTIR spectroscopy to study the extent of exchange and the apparent transition temperature in both pure recombinant human serum albumin (rHSA) and rHSA formulated with sucrose or trehalose. H/D exchange of freeze-dried formulations at 11% RH and temperatures from 30 to 80°C was monitored. Protein stability against aggregation at 40°C/11% RH for 6 months was assessed by size exclusion chromatography (SEC). RESULTS Both sucrose and trehalose showed equivalent protection of protein secondary structure by FTIR. The rHSA:sucrose formulation showed superior long-term stability at 40°C by SEC over the trehalose formulation, but the apparent Td determined from H/D exchange was much higher in the trehalose formulation. Instead, the extent of H/D exchange (X∞) was lower in the sucrose formulation at the temperature of the stability studies (40°C) than found for the trehalose formulation, which was consistent with better stability in the sucrose formulation. CONCLUSIONS While apparent Td did not correlate with protein stability for rHSA, the extent of H/D exchange, X∞, did.
