Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

open access: yesChirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Cocrystallization and Micronization as Strategies to Optimize the Bioavailability of Naringin and Naringenin Molecules: A Comprehensive Review of In Vivo and In Vitro Pharmaceutical Applications

open access: yesCrystal Research and Technology, Volume 61, Issue 7, July 2026.
Naringin and naringenin exhibit well‐recognized therapeutic potential; however, they face limitations related to solubility and bioavailability. Micronization increases surface area and enhances absorption. Notably, cocrystallization stands out as a primary strategy for particle optimization, as it refines physicochemical properties, improves ...

Crystal structures and hydrogen-bonding analysis of a series of benzamide complexes of zinc(II) chloride

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2021
Ionic co-crystals are co-crystals between organic molecules and inorganic salt coformers. Co-crystals of pharmaceuticals are of interest to help control polymorph formation and potentially improve stability and other physical properties.

Characterization of Structure, Properties, and Energetic Performance of a 1:1 Ammonium Dinitramide‐3,4‐Diaminofurazan Cocrystal

open access: yesPropellants, Explosives, Pyrotechnics, Volume 51, Issue 7, Page 1044-1057, July 2026.
Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...
