RS, S (+) - and R (−)-ibuprofen cocrystal polymorphs: Vibrational spectra, XRD measurement and DFT calculation studies

open access: yesHeliyon
In this paper, cocrystal polymorphs of RS-ibuprofen (RS-IBU), S (+)-ibuprofen (S(+)-IBU), R (−)-ibuprofen (R(−)-IBU) with nicotinamide (NIC) were synthesized by different methods. RS-IBU is a chiral drug with only one chiral center in the molecule, which

Decreasing the hygroscopicity of ammonium dinitramide (ADN) through cocrystallization

open access: yesEnergetic Materials Frontiers, 2022
To decrease the hygroscopicity of ADN—a energetic oxidizer, this study developed a new cocrystal composed of ADN and 18C6 (18-crown-6) at a 1:1 ​M ratio through cocrystallization using the solvent evaporation method.

Cocrystal Transition Points: Role of Cocrystal Solubility, Drug Solubility, and Solubilizing Agents [PDF]

open access: yesMolecular Pharmaceutics, 2015
In this manuscript we bring together concepts that are relevant to the solubilization and thermodynamic stability of cocrystals in the presence of drug solubilizing agents. Simple equations are derived that allow calculation of cocrystal solubilization and transition point solubility.

Charge Transport in Ternary Charge‐Transfer Solid Solution Single Crystals

open access: yesAdvanced Functional Materials, EarlyView.
This study deconvolutes the roles of indirect (superexchange) and direct electronic coupling on charge transport in single crystals of an organic charge‐transfer molecular semiconductor (OSC). This model system elegantly demonstrates that structural defects introduced by chemical dopants play a significant role in the electronic performance ...

Kinetics and Inhibition Studies of the L205R Mutant of cAMP-Dependent Protein Kinase Involved in Cushing’s Syndrome [PDF]

open access: yes, 2018
Overproduction of cortisol by the hypothalamus–pituitary–adrenal hormone system results in the clinical disorder known as Cushing\u27s syndrome. Genomics studies have identified a key mutation (L205R) in the α‐isoform of the catalytic subunit of cAMP ...

Thermally Activated Delayed Fluorescence in Phase‐Separated Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
A supramolecular, phase‐separation driven strategy yields charge transfer (CT) complexes from alternating electron‐deficient pyromellitic diimide and electron‐rich 4,5‐dibromoveratrole. The resulting CT complexes self‐assemble into lamellar nanosheets with nanometer‐sized domains that exhibit thermally activated delayed fluorescence (TADF) at room ...
