Praziquantel Fifty Years on: A Comprehensive Overview of Its Solid State

open access: yesPharmaceutics, 2023
This review discusses the entire progress made on the anthelmintic drug praziquantel, focusing on the solid state and, therefore, on anhydrous crystalline polymorphs, amorphous forms, and multicomponent systems (i.e., hydrates, solvates, and cocrystals).

Combined Use of Structure Analysis, Studies of Molecular Association in Solution, and Molecular Modelling to Understand the Different Propensities of Dihydroxybenzoic Acids to Form Solid Phases

open access: yesPharmaceutics, 2021
The arrangement of hydroxyl groups in the benzene ring has a significant effect on the propensity of dihydroxybenzoic acids (diOHBAs) to form different solid phases when crystallized from solution. All six diOHBAs were categorized into distinctive groups

Study on Fundamental Properties of Solvate Electrolytes and Their Application in Batteries

open access: yesElectrochemistry, 2022
Li salts and polar solvents form solvates, and certain solvates have low melting temperatures and remain in a liquid state at room temperature. Liquid-state solvates exhibit ionic conductivity and can be used as electrolytes in lithium batteries.

Crystal Structure, Stability and Desolvation of the Solvates of Sorafenib Tosylate

open access: yesCrystals, 2019
In this study, three solvates of sorafenib tosylate were obtained from methanol, ethanol and n-methyl-2-pyrrolidone (NMP) after solvate screening and the effect of solvent on the formation of solvate was analyzed. The solvents with high value of polarity/

A Comparison Study of Roseolumiflavin Solvates: Structural and Energetic Perspective on Their Stability

open access: yesCrystals, 2023
Roseolumiflavin is a deep red microcrystalline derivative of isoalloxazine that exhibits a weak photophysical activity in the solid state. In aqueous as well as in acidic solution of formic or acetic acid, respectively, it tends to form solvates. Herein,

Solvate Formation of Bis(demethoxy)curcumin: Screening and Characterization

open access: yesCrystals, 2018
Solvate formation of bis(demethoxy)curcumin (BDMC) was screened. Six solvates were obtained out of the nineteen solvents investigated. In the present work, three solvates, i.e., BDMC-tetrahydrofuran (THF), BDMC-1,4-dioxane (DIO) and BDMC-dimethyl ...
