A robust, highly water stable, microporous MOF, [Zn 8 (O) 2 (CDDB) 6 (DMF) 4 (H 2 O)] {where CDDB = 4,4′-(9- H carbazole-3,6-diyl)dibenzoic acid}, was synthesized based on an open N–H site by a solvothermal process and exhibited an outstanding loading capacity and satisfactory release capability for 5-fluorouracil, with a negligible cytotoxicity effect.
Powder compaction data of three polymorphic Forms I (shearing), II (bending) and III (brittle) of 6-chloro-2,4-dinitroaniline demonstrates a direct relationship among mechanical properties, crystal structure and tableting behaviour, showing the essence of structure based assessment of mechanical properties of crystals, e.g., for identifying more efficient API formulation and manufacture processes.

Pharmaceutical co-crystals have gained significant attention in recent years as a promising green and sustainable method for poorly soluble drugs to improve their solubility, stability, and bioavailability. In the drug development research field, it is an extremely useful technique as it does not require a large number of synthetic steps as well a minimum amount of solvent is utilized or sometimes without solvent. This review presents a comprehensive investigation into the design, synthesis, characterization, and evaluation of pharmaceutical co-crystals. The study focuses on exploring different strategies for co-crystal formation, including co-grinding, solvent evaporation, and liquid-assisted grinding. Various characterization techniques such as SCXRD, PXRD, FTIR, and DSC were employed to confirm the formation and structural features of the co-crystals. The article also highlights the significance of understanding the intermolecular interactions within co-crystals and their influence on physicochemical properties. Furthermore, the article discusses the potential applications of pharmaceutical co-crystals in enhancing drug solubility, dissolution rate, and oral bioavailability, leading to improved therapeutic efficacy. Overall, this review provides valuable insights into the design and development of pharmaceutical co-crystals, offering a promising avenue for overcoming the difficulties brought on by poorly soluble drugs.
