The first nano-cocrystal formulation of marine drug cytarabine with uracil based on cocrystal nanonization strategy for long-acting injection exhibiting enhanced antitumor activity. Int J Pharm 2023; 644:123300. [PMID: 37567370 DOI: 10.1016/j.ijpharm.2023.123300] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 08/05/2023] [Accepted: 08/08/2023] [Indexed: 08/13/2023]
Abstract
To emphasize the superiority of uracil (UR) in ameliorating biopharmaceutical characteristics of marine antitumor medicine cytarabine (ARA), thus gaining some innovative opinions for the exploitation of nanococrystal formulation, a cocrystal nanonization strategy is proposed by integrating cocrystallization and nanosize preparation techniques. For one thing, based on UR's unique structural features and natures together with advantages of preferential uptake by tumor cells, cocrystallizing ARA with UR is expected to improve the in vitro/vivo performances. For another, the nanonization procedure is oriented towards maintaining the long-term effective drug level. Along this route, a cocrystal of ARA with UR, viz., ARA-UR, is successfully synthesized and then transformed into nano-cocrystal. The cocrystal structure is precisely confirmed by various methods, demonstrating that a 1:1 ARA and UR in the crystal forms cytosine-UR hydrogen-bonding interactions, thus constructing supramolecular frameworks by strong π-π stacking interplays; while the nano-cocrystal is block-shaped particles of 562.70 nm with zeta potential -33.40 mV. The properties of cocrystal ARA-UR and its nano-cocrystal in vitro/vivo are comparatively explored by theoretical calculations and experimental analyses, revealing that permeability of both is significantly increased than ARA per se. Notably, the meliorative natures of both the cocrystal and nano-cocrystal in vitro bring excellent antitumor activity, but the latter has greater strengths over the former. More notably, the nano-cocrystal can sustain effective concentration for a relatively longer time, causing lengthened retention time and better absorption in vivo. The contribution offers a fire-new dosage form of ARA for long-lasting delivery, thus filling the vacancy in nanococrystal studies about marine drugs.

Abstract
Due to the subtle balance of intermolecular interactions that govern structure-property relations, predicting the stability of crystal structures formed from molecular building blocks is a highly non-trivial scientific problem. A particularly active and fruitful approach involves classifying the different combinations of interacting chemical moieties, as understanding the relative energetics of different interactions enables the design of molecular crystals and fine-tuning of their stabilities. While this is usually performed based on the empirical observation of the most commonly encountered motifs in known crystal structures, we propose to apply a combination of supervised and unsupervised machine-learning techniques to automate the construction of an extensive library of molecular building blocks. We introduce a structural descriptor tailored to the prediction of the binding (lattice) energy and apply it to a curated dataset of organic crystals, exploiting its atom-centered nature to obtain a data-driven assessment of the contribution of different chemical groups to the lattice energy of the crystal. We then interpret this library using a low-dimensional representation of the structure-energy landscape and discuss selected examples of the insights into crystal engineering that can be extracted from this analysis, providing a complete database to guide the design of molecular materials.

Pharmaceutical Cocrystals of Ethenzamide: Molecular Structure Analysis Based on Vibrational Spectra and DFT Calculations. Int J Mol Sci 2022; 23:ijms23158550.

Abstract
Pharmaceutical cocrystals can offer another advanced strategy for drug preparation and development and can facilitate improvements to the physicochemical properties of active pharmaceutical ingredients (APIs) without altering their chemical structures and corresponding pharmacological activities. Therefore, cocrystals show a great deal of potential in the development and research of drugs. In this work, pharmaceutical cocrystals of ethenzamide (ETZ) with 2,6-dihydroxybenzoic acid (26DHBA), 2,4-dihydroxybenzoic acid (24DHBA) and gallic acid (GA) were synthesized by the solvent evaporation method. In order to gain a deeper understanding of the structural changes after ETZ cocrystallization, terahertz time domain spectroscopy (THz-TDS) and Raman spectroscopy were used to characterize the single starting samples, corresponding physical mixtures and the cocrystals. In addition, the possible molecular structures of ETZ-GA, ETZ-26DHBA and ETZ-24DHBA cocrystals were optimized by density functional theory (DFT). The results of THz and Raman spectra with the DFT simulations for the three cocrystals revealed that the ETZ-GA cocrystal formed an O−H∙∙∙O hydrogen bond between the -OH of GA and oxygen of the amide group of the ETZ molecule, and it was also found that ETZ formed a dimer through a supramolecular amide–amide homosynthon; meanwhile, the ETZ-26DHBA cocrystal was formed by a powerful supramolecular acid–amide heterosynthon, and the ETZ-24DHBA cocrystal formed the O−H∙∙∙O hydrogen bond between the 4-hydroxy group of 24DHBA and oxygen of the amide group of the ETZ molecule. It could be seen that in the molecular structure analysis of the three cocrystals, the position and number of hydroxyl groups in the coformers play an essential role in guiding the formation of specific supramolecular synthons.

Abstract
Co-crystal innovation is an opportunity in drug development for both scientists and industry. In line with the “green pharmacy” concept for obtaining safer methods and advanced pharmaceutical products, co-crystallization is one of the most promising approaches to find novel patent drugs, including non-steroidal anti-inflammatory drugs (NSAID). This kind of multi-component system improves previously poor physicochemical and mechanical properties through non-covalent interactions. Practically, there are many challenges to find commercially viable co-crystal drugs. The difficulty in selecting co-formers becomes the primary problem, followed by unexpected results, such as decreased solubility and dissolution, spring and parachute effect, microenvironment pH effects, changes in instability, and polymorphisms, which can occur during the co-crystal development. However, over time, NSAID co-crystals have been continuously updated regarding co-formers selection and methods development.

Abstract
Primarily composed of organic molecules, pharmaceutical materials, including drugs and
excipients, frequently exhibit physicochemical properties that can affect the formulation, manufacturing
and packing processes as well as product performance and safety. In recent years, researchers
have intensively developed Crystal Engineering (CE) in an effort to reinvent bioactive molecules
with well-known, approved pharmacological effects. In general, CE aims to improve the physicochemical
properties without affecting their intrinsic characteristics or compromising their stability.
CE involves the molecular recognition of non-covalent interactions, in which organic materials are
responsible for the regular arrangement of molecules into crystal lattices. Modern CE, encompasses
all manipulations that result in the alteration of crystal packing as well as methods that disrupt crystal
lattices or reduce the size of crystals, or a combination of them. Nowadays, cocrystallisation has been
the most explored strategy to improve solubility, dissolution rate and bioavailability of Active Pharmaceutical
Ingredients (API). However, its combinatorial nature involving two or more small organic
molecules, and the use of diverse crystallisation processes increase the possible outcomes. As a result,
numerous organic materials can be obtained as well as several physicochemical and mechanical
properties can be improved. Therefore, this review will focus on novel organic solids obtained when
CE is applied including crystalline and amorphous, single and multicomponent as well as nanosized
ones, that have contributed to improving not only solubility, dissolution rate, bioavailability permeability
but also, chemical and physical stability and mechanical properties.

Abstract
Oxyresveratrol (ORV) is a naturally extracted compound with many pharmacological activities. However, information about the crystalline form is not known when considering the development of a form for oral dosage. Cocrystal engineering offers drug molecular understanding and drug solubility improvements. Thus, we attempted cocrystallization of ORV using 10 carboxylic acids as a coformer at a 1:1 M ratio. Each combination was processed with liquid-assisted grinding, solvent evaporation and a slurry method, then characterized by powder X-ray powder diffraction (PXRD), conventional and low-frequency Raman spectroscopy and thermal analysis. The solubility, dissolution and permeation studies across Caco-2 cell monolayers were conducted to evaluate the ORV samples. A screening study revealed that an ORV and citric acid (CTA) cocrystal formed by ethyl acetate-assisted grinding had characteristic PXRD peaks (14.0 and 16.5°) compared to those of ORV dihydrate used as a starting material. Low-frequency Raman measurements, with peaks at 100 cm-1, distinguished potential cocrystals among three processing methods while conventional Raman could not. An endothermic melt (142.2°C) confirmed the formation of the novel crystalline complex. The solubility of the cocrystal in the dissolution media of pH 1.2 and 6.8 was approximately 1000 µg/mL, a 1.3-fold increase compared to ORV alone. In vitro cytotoxicity studies showed that the cocrystal and physical blend were not toxic at concentrations of 25 and 12.5 µM ORV, respectively. The ORV-CTA cocrystal enhanced the cellular transport of ORV across Caco-2 monolayers. Therefore, cocrystallization could be used to improve aqueous solubility and permeability, leading to better oral bioavailability of ORV.

However, the crystallization of amorphous solid dispersions during storage, or from elevated supersaturation once dissolved, compromise the solubility advantage of delivery in the amorphous phase. To combat this phenomenon, polymer additives are often included in solid dispersions to inhibit crystallization; however, the optimal properties for polymer to stabilize against crystallization are not fully understood, and furthermore, it is not known how inhibition of precipitation from solution is related to the propensity of a polymer to inhibit crystallization from the amorphous phase. Here, polymers of varied hydrophobicity are employed as crystallization inhibitors in supersaturated solutions and amorphous solid dispersions of the BCS Class II pharmaceutical ethenzamide to investigate the chemical features of polymer that lead to long-term stability for a hydrophobic pharmaceutical. A postpolymerization functionalization strategy was employed to alter the hydrophobicity of poly( N-hydroxyethyl acrylamide) without changing physical properties such as number-average chain length. It was found that supersaturation maintenance for ethenzamide is improved by increasing the hydrophobicity of dissolved polymer in aqueous solution. Furthermore, amorphous solid dispersions of ethenzamide containing a more hydrophobic polymer showed superior stability compared to those containing a less hydrophobic polymer. This trend of increasing polymer hydrophobicity leading to improved amorphous stability is interpreted by parsing the effects of water absorption in amorphous solid dispersions using intermolecular interaction strengths derived from global structural analysis. By comparing the structure-function relationships, which dictate stability in solution and amorphous solid dispersions, the effect of hydrophobicity can be broadly understood for the design of polymers to impart stability throughout the application of amorphous solid dispersions.
