Biochem Biophys Res Commun 2024; 738:150546. [PMID: 39154554 DOI: 10.1016/j.bbrc.2024.150546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2024] [Revised: 08/09/2024] [Accepted: 08/12/2024] [Indexed: 08/20/2024]
Abstract
A new cocrystalline form of metronidazole (MET) with propyl gallate (PRO), referred to as MET-PRO, has been successfully synthesized and characterized. Structural characterization reveals that MET and PRO are present in a 1:1 ratio within the cocrystal lattice, with one water molecule equivalent incorporated into the structure. This arrangement facilitates the formation of MET-PRO heterodimers and multiple stable units, collectively constructing a three-dimensional supramolecular network. The solubility and permeability of the current cocrystal, along with the parent drug MET, are evaluated under physiological pH conditions. Experimental findings reveal that MET within the cocrystal exhibits a 1.54-2.37 folds increase in solubility and approximately a threefold improvement in permeability compared to its standalone form. Intriguingly, these concurrent enhancements in the physicochemical properties of MET lead to augmented antibacterial activity in vitro, evidenced by a reduction in minimum inhibitory concentration. Even more intriguingly, the enhanced physicochemical properties observed in vitro for the current cocrystal translate into tangible pharmacokinetic benefits in vivo, characterized by prolonged half-life and enhanced bioavailability. Consequently, this research not only introduces a fresh crystal structure for antibacterial medication but also presents approach for optimizing drug properties across in vitro and in vivo settings, while concurrently bolstering the antibacterial effectiveness of MET through pharmaceutical cocrystallization techniques.

Abstract
PURPOSE The primary problem with climbazole (CLB), a broad-spectrum imidazole antifungal drug, is its low water solubility. In order to increase its water solubility and antifungal activity, three new multi-component crystals were synthesized in this work, and the intermolecular interactions were systematically studied. This work helps to optimize the CLB product formulation and extend its application prospects. METHODS In this work, three novel multi-component crystals, CLB-malonic acid (CLB-MA) salt, CLB-succinic acid (CLB-SA) cocrystal and CLB-adipic acid (CLB-AA) cocrystal, were successfully synthesized. And the crystal structure, thermodynamic properties, solubility, dissolution, hygroscopicity, and antifungal activity of the three multi-component crystals were fully characterized by single-crystal X-ray diffraction (SCXRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic water vapor adsorption (DVS) and powder dissolution tests, etc. The molecular interactions and molecular stacking in multi-component crystals were studied by Hirshfeld surface (HS), molecular surface electrostatic potential (MEP), interaction region indication (IRI) and atom and molecule (AIM) techniques. RESULTS The results show that the three multi-component crystals have good moisture resistance stability, and their water solubility is 6-22 times that of pure CLB. Meanwhile, the measurement of the minimum inhibitory concentration (MIC) proves that the cocrystal/salt has a stronger antifungal activity than climbazole. Quantum chemistry calculations of crystal structure visualized and quantified the interactions that exist in multi-component crystals, and explored the microscopic mechanisms underlying the different performance of multi-component crystals.

Abstract
We present two iridium complexes 1H+ and 2H+ that contain cationic ligands to extend the knowledge of charge-assisted hydrogen bonding (CAHB), which counts among the strongest non-covalent bonding interactions. Upon protonation, both complexes were converted into new hydrogen-bonding arrays with various selectivity for respective H-bonding partners. This study compares the association strengths of four hydrogen-bonding co-systems, emphasizing the roles of CAHB in supramolecular systems. We determined that the cationic charge in these systems contributed up to 2.7 kJ mol−1 in the H-bonding complexation processes.

Abstract
In this study, various structurally similar aliphatic dicarboxylic acids, namely, succinic acid, glutaric acid, adipic acid, and pimelic acid, were employed as coformers to obtain phase pure cocrystals with berberine chloride (BCl) by a slow solvent evaporation method. The structures of the four novel salt-cocrystals of BCl were determined by single crystal X-ray diffraction analysis and their solid-state properties were characterized. Compared with BCl·2H2O, all the cocrystals showed a higher melting point, improved powder dissolution and intrinsic dissolution rate (IDR), and lower hygroscopicity. It is noteworthy that the melting points and IDRs of these cocrystals exhibit an odd-even alternation with the carbon chain length of the acids.

Abstract
Base on improving the solubility and permeability of enoxacin (EX) to enhance the antibacterial activity in vitro, three new pharmaceutical salts/cocrystals of EX with oxalic acid (EX·0.5(C2H2O4)·2(H2O)), malonic acid ((HEX)·C3H3O4) and fumaric acid ((HEX)·C4H3O4) have been designed, synthesized and characterized. Comprehensive analysis structure and Hirshfeld surface reveal that the hydrogen bonds/CAHBs formed by the N atom in the piperazine ring from EX molecule with the carboxylic acid group in the coformer could form a stable crystal structure. It is universally acknowledged that improving the solubility of the EX (BCS class II) to make it a BCS class I drug would obtain a Bioequivalence of immunity to the drug trial. The solubilities of three pharmaceutical salts/cocrystals of EX with dicarboxylic acids are consistent with expectation that they are dramatically improved in pure water than pure enoxacin, and the solubility order of three pharmaceutical salts/cocrystals of EX is consistent with coformers solubility. The permeabilities of three pharmaceutical salts/cocrystals of EX are improved compared with the pure enoxacin, and the variation tendency is consistent with the solubilities of three pharmaceutical salts/cocrystals of EX. In addition, the antibacterial activities in vitro of three pharmaceutical salts/cocrystals of EX are improved compared with the corresponding parent compound (EX), which change the order is consistent with the solubility and permeability. Simultaneously, the hygroscopic stabilities of three pharmaceutical salts/cocrystals are surpassing pure EX, and the hygroscopic stability of molecular cocrystal EX-OXA is better than ionic cocrystal EX-MLO and EX-FUM. This implies that preparation of the pharmaceutical salts/cocrystals of EX with oxalic acid, malonic acid and fumaric acid could not only enhance the antibacterial activity of EX, which base on improving the solubility and permeability of EX, but also improve the hygroscopic stability of EX.

Abstract
Two azilsartan–piperazine salt solvates and a monohydrate feature crystal structural diversity and improve the azilsartan solubility over that of the free Az form. Az–Pz·EtOH and Az–Pz·H2O improve the plasma azilsartan concentration Cmax and AUC over the free Az form.

Investigations on the Solubility of Vortioxetine Based on X-ray Structural Data and Crystal Contacts. CRYSTALS 2019.

Abstract
Investigation on the solid-state pharmaceutical chemistry has been known as an intriguing strategy to not only modify the physicochemical properties of drugs but also expand the solid form landscape. Vortioxetine (VOT) is an effective but poorly soluble antidepressant. To improve the solubility of vortioxetine and expand possible solid forms, in this paper, four novel solid forms of vortioxetine with dihydroxybenzoic acids (VOT-23BA, VOT-24BA-TOL, VOT-25BA, and VOT-26BA, 23BA = 2,3-dihydroxybenzoic acid, 24BA = 2,4-dihydroxybenzoic acid, 25BA = 2,5-dihydroxybenzoic acid, 26BA = 2,6-dihydroxybenzoic acid, and TOL = toluene) were synthesized first by a solvent evaporation method and then characterized by single-crystal X-ray diffraction (SCXRD), thermal, and XRD techniques. VOT-24BA-TOL, VOT-25BA, and VOT-26BA, showed similar [2+2] tetrameric R 4 4 (12) hydrogen bonds by acid-piperazine heterosynthon. In the VOT-23BA-H2O salt, the VOT cation and 23BA anion interacted through protonated piperazine-hydroxyl N-H···O hydrogen bonds, not protonated piperazine-deprotonated carboxylic acid N-H···O hydrogen bonds. Solubility studies were carried out in purified water and it was found that the VOT-23BA-H2O, VOT-25BA, and VOT-26BA salts exhibited an increase in water compared to pure VOT. The solubility of the stabilized salt formations followed the order of VOT-25BA > VOT-26BA > VOT-23BA-H2O in purified water.
