Temozolomide Cocrystals with Carboxamide Coformers
Crystal Growth & Design, 2013Temozolomide (TMZ) is an antitumor prodrug of broad spectrum antineoplastic activity. TMZ is stable in acidic medium (pH 7). In continuation of our efforts to design stable cocrystals of TMZ with partners such as organic acids (pKa 2–5) and a salt dihydrate with hydrochloric acid, we report herein TMZ cocrystals with amide coformers, e.g ...

Exploring potential coformers for oxyresveratrol using principal component analysis
International Journal of Pharmaceutics, 2020Oxyresveratrol (OXY) exhibits poor bioavailability due to its low solubility. Cocrystals are effective in improving solubility of OXY. In this study, principal component analysis (PCA) was employed for coformer selection using 5 variables (solubility parameter, logP, hydrogen bonding acceptor, hydrogen bonding donor and molecular volume).

CrystEngComm, 2013
Four original cocrystal structures incorporating a zwitterionic amino acid, prolinium, and a therapeutical agent from profen pharmaceutical family, naproxen, are highlighted and characterized in this study. Powder X-ray diffraction and differential scanning calorimetry permits the observation of the formation of the new structures, obtained by liquid ...

Dissolution Profiles of Carbamazepine Cocrystals with Cis–Trans Isomeric Coformers
Pharmaceutical Research, 2022The purpose of the present study was to investigate the dissolution profiles of cocrystals with cis-trans isomeric coformers. Previously, the carbamazepine (CBZ) cocrystals with even-carbon dicarboxylic acids showed higher supersaturation than those with odd-carbon ones, attributed to particle surface solution-mediated phase transformation (PS-SMPT) to

Multicomponent solids of diclofenac with pyridine based coformers
Journal of Molecular Structure, 2020Abstract The present study reports nine crystalline forms of diclofenac acid which include cocrystals, salts, salt-cocrystals and salt hydrates with pyridines and amines based coformers utilizing acid … pyridine synthon. All the solids were successfully prepared and structurally characterized through PXRD, ATR, DSC and single crystal XRD. The crystal

Mechanochemical Transformations of Pharmaceutical Cocrystals: Polymorphs and Coformer Exchange
Chemistry – A European JournalAbstractTransformations of solid samples under solvent‐free or minimal solvent conditions set the future trend and define a modern strategy for the production of new materials. Of the various technologies tested in recent years, the mechanochemical approach seems to be the most promising for economic and ecological reasons.

CRYSTAL DESIGN APPROACHES FOR SELECTION OF COFORMERS
INTERNATIONAL JOURNAL OF SCIENTIFIC RESEARCHEnhancing the solubility and dissolution of drugs is being an important step in research. To select coformers for crystallization which can increase solubility is an important step to be considered. In this review the different approaches for the selection of coformers is explained. The pKa based model can be considered as pre-tool.
