At equilibrium with the solid theophylline – oxalic acid co-crystal, the theophylline concentration is only 60 % of the corresponding value for the Given that stability, solubility and permeability are in general inversely correlated, the entacapone-theophylline hydrate cocrystal is a unique example of the thermodynamically stable cocrystal Mechanistically, theophylline acts as a phosphodiesterase inhibitor, adenosine receptor blocker, and histone deacetylase activator
Etofylline | C9H12N4O3 | CID 1892 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety A new co-crystal of theophylline and phthalic acid with 1:1 molar ratio has been prepared
Download scientific diagram | The Structure of Theophylline (TPH) from publication: Preparation method and characterization of inclusion complex of theophylline/beta cyclodextrin | beta This occurred due to the high solubility of salicylic acid in acetonitrile compared to theophylline form II in acetonitrile, which shifts the stable cocrystal region in the TPD to the more soluble Objective: Co-crystal is a crystal form which consists of two or more components in a specific stoichiometric ratio
