摘要
In order to improve the aqueous solubility of clotrimazole (CLT), an effective antifungal agent, its new multicomponent crystals were developed according to crystal engineering. To efficiently synthesize the multicomponent solids, a protocol which combined a virtual cocrystal screening tool based on the conductor-like screening model for realistic solvents (COSMO-RS) and the experimental liquid-assisted grinding (LAG) method was applied. As a result, fourteen multicomponent crystals were obtained from 21 potential coformers, including 5 previously reported ones. Nine novel multicomponent crystals were identified and characterized by single crystal X-ray diffraction, powder X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis and Fourier-transform infrared spectroscopy. Intermolecular interactions were elucidated by Hirshfeld surface analysis, and the origin of the cocrystals/salts was explained using molecular electrostatic potential surfaces. Finally, powder dissolution experiments were carried out. Compared with CLT, some multicomponent crystals showed an improvement in solubility (3.13-1.53 times) and dissolution rate.
