Abstract
Nanocrystals refer to materials with at least one dimension smaller than 100 nm, composing of atoms arranged in single crystals or polycrystals. Nanocrystals have significant research value as they offer unique advantages over conventional pharmaceutical formulations, such as high bioavailability, enhanced targeting selectivity and controlled release ability and are therefore suitable for the delivery of a wide range of drugs such as insoluble drugs, antitumor drugs and genetic drugs with broad application prospects. In recent years, research on nanocrystals has been progressively refined and new products have been launched or entered the clinical phase of studies. However, issues such as safety and stability still stand that need to be addressed for further development of nanocrystal formulations, and significant gaps do exist in research in various fields in this pharmaceutical arena. This paper presents a systematic overview of the advanced development of nanocrystals, ranging from the preparation approaches of nanocrystals with which the bioavailability of poorly water-soluble drugs is improved, critical properties of nanocrystals and associated characterization techniques, the recent development of nanocrystals with different administration routes, the advantages and associated limitations of nanocrystal formulations, the mechanisms of physical instability, and the enhanced dissolution performance, to the future perspectives, with a final view to shed more light on the future development of nanocrystals as a means of optimizing the bioavailability of drug candidates. This article is categorized under: Therapeutic Approaches and Drug Discovery > Emerging Technologies Nanotechnology Approaches to Biology > Nanoscale Systems in Biology.

Abstract
Drug nanocrystals, which are comprised of active pharmaceutical ingredients and only a small amount of essential stabilizers, have the ability to improve the solubility, dissolution and bioavailability of poorly water-soluble drugs; in turn, drug nanocrystal technology can be utilized to develop novel formulations of chemotherapeutic drugs. Compared with passive targeting strategy, active tumor-targeted drug delivery, typically enabled by specific targeting ligands or molecules modified onto the surface of nanomedicines, circumvents the weak and heterogeneous enhanced permeability and retention (EPR) effect in human tumors and overcomes the disadvantages of nonspecific drug distribution, high administration dosage and undesired side effects, thereby contributing to improving the efficacy and safety of conventional nanomedicines for chemotherapy. Continuous efforts have been made in the development of active tumor-targeted drug nanocrystals delivery systems in recent years, most of which are encouraging and also enlightening for further investigation and clinical translation.

Int J Pharm 2021; 604:120729. [PMID: 34029666 DOI: 10.1016/j.ijpharm.2021.120729] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 05/05/2021] [Accepted: 05/19/2021] [Indexed: 10/21/2022]
Abstract
This study developed a nanocrystals-in-microparticles (NCs/MPs) technology for improving dissolution and oral absorption of poorly soluble drugs. Hydroxycamptothecin (HCPT) was selected as a model drug and prepared to be nanocrystals (HCPT-NCs) by acid-alkali based precipitation. The HCPT-NCs were rod like shape with the length of 250 nm and the width of 50 nm. Then, the chitosan and sodium alginate were selected as microparticles matrix to encapsulate the HCPT-NCs. The HCPT-NCs were entrapped in microparticles with a D50 value of 15 µm. The drug loading capacity of microparticles achieved more than 40% (w/w) by NCs/MPs technology. The powder X-ray diffraction showed the crystal structure of HCPT in microparticles was same as nanocrystals, indicating that the preparation of microparticles could not destroy the nanocrystals. The in vitro release demonstrated that microparticles could protect the NCs in gastric fluid and release NCs in intestinal fluid. Furthermore, the oral bioavailability of HCPT in NCs/MPs was improved by 18-fold compared to bulk HCPT and 2.1-fold compared to HCPT-NCs as tested by a rat model. Therefore, NCs/MPs technology is a promising and high effective approach to improve the oral bioavailability of poorly soluble drugs.

Abstract
Solubilization studies of tadalafil (TDF) have recently improved the dissolution (%) using weak acids and bases in our group. However, the weak acid formulations have a low dissolution (%) of TDF as limitation. Thus, the purpose of this study was to improve the dissolution (%) of TDF over 90% in distilled water (DW) by weak acid-chitosan based multi-system. The SD formulation (SD11: TDF, tartaric acid, chitosan, Aerosil®200, and PVP/VA S-630 in a 1:2:1:1:2 weight ratio) showed higher dissolution (%) of TDF by 5.0-, 6.0-, and 5.8-fold at 60 min than that of Cialis® in DW and pH 1.2 and pH 6.8 buffers, respectively. The physical properties of the SD11 formulation were changed. Moreover, the SD11 formulation maintained stability for 3 months. In conclusion, the solubilization of TDF using chitosan was successfully performed for the first time.

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
The aim of this study is to develop a novel RGD and TAT co-modified docetaxel (DTX)-loaded liposome (LP) by the emulsification-solvent evaporation method. The prepared LPs were found to be in the size of 100 nm–110 nm. The transmission electron microscope photomicrographs were smooth, sub-spherical in shape, and aggregated to form small clusters. The DTX cumulative release from TAT and RGD co-modified LPs was significantly higher than that from other LPs due to decreased diffusion distance. Results of cell uptake showed that surface modification could indicate when cell internalization was changed and more drugs entered the cells successfully. Surprisingly, TAT and RGD co-modified DTX-LPs demonstrated a superior antiproliferative effect on A549 cells with a possible mechanism that suppressed the multidrug resistance phenomenon and exhibited a clear synergistic effect. In antitumor study, our results indicated that the form of TAT and RGD co-modified LPs had a better antitumor effect in vivo than the other formulations.

Abstract
The aim of the present work was to tackle the solubility issue of a biopharmaceutics classification system (BCS)-II drug, aceclofenac. Although a number of attempts to increase the aqueous solubility have been made, none of the methods were taken up for scale-up. Hence size reduction technique by a top-down approach using wet milling process was utilized to improve the solubility and, consequently, the dissolution velocity of aceclofenac. The quality of the final product was ensured by Quality by Design approach wherein the effects of critical material attributes and critical process parameters were assessed on the critical quality attributes (CQAs) of nanocrystals. Box–Behnken design was applied to evaluate these effects on critical quality attributes. The optimized nanocrystals had a particle size of 484.7±54.12 nm with a polydispersity index (PDI) of 0.108±0.009. The solid state characterization of the formulation revealed that the crystalline nature of the drug was slightly reduced after the milling process. With the reduced particle size, the solubility of the nanocrystals was found to increase in both water and 0.1 N HCl when compared with that of unmilled pure aceclofenac. These results were further supported by in vitro release studies of nanocrystals where an appreciable dissolution velocity with 100.07%±2.38% release was observed for aceclofenac nanocrystals compared with 47.66%±4.53% release for pure unmilled aceclofenac at the end of 2 h. The in vivo pharmacokinetic data generated showed a statistically significant increase in the Cmax for aceclofenac nanocrystals of 3.75±0.28 µg/mL (for pure unmilled aceclofenac Cmax was 1.96±0.17 µg/mL). The results obtained indicated that the developed nanocrystals of aceclofenac were successful in improving the solubility, thus the absorption and bioavailability of the drug. Hence, it may be a viable and cost-effective alternative to the current therapy.

Abstract
The purpose of this study was to develop the surface modification of docetaxel nanocrystals (DTX-NCs) with apo-Transferrin human (Tf) for improving the cellular uptake and cytotoxicity of DTX. DTX-NCs were prepared by a nanoprecipitation method, and the surface modified with Tf by an adsorption method (Tf-DTX-NCs). The morphology and particle size of DTX-NCs and Tf-DTX-NCs were characterized using a field emission scanning electron microscope and zetasizer. An in vitro drug release study was performed in phosphate-buffered saline containing 0.5% (w/v) Tween 80 for 24 hours. Cellular uptake was studied at 0.5, 1, and 2 hours. A cytotoxicity study was performed using the A549 (human lung cancer) cell line after 24-, 48-, and 72-hour treatments. The mean sizes were 295±97 and 398±102 nm for DTX-NCs and Tf-DTX-NCs, respectively. Tf-DTX-NCs and DTX-NCs exhibited rapid drug release, whereas DTX (pure) was slowly released. Tf-DTX-NCs showed higher cellular uptake than DTX-NCs in confocal microscopic and quantitative studies. Moreover, at DTX concentration of 100 µg/mL, Tf-DTX-NCs (82.6%±0.8%) showed higher cytotoxicity than DTX-NCs (77.4%±4.1%) and DTX (pure; 20.1%±4.6%) for 72-hour treatment. In conclusion, Tf-DTX-NCs significantly improved the cellular uptake and cytotoxicity of DTX in the A549 cell line.

Abstract
To overcome the toxicity of excipient or blank nanoparticles for drug delivery nano-system, the surface modified paclitaxel nanocrystals (PTX-NC) have been developed. PTX-NCs were prepared by nano-precipitation method. The surface of PTX-NCs were modified by grafting with apo-transferrin (Tf) or hyaluronic acid (HA). The physical properties of PTX-NCs were evaluated by field emission scanning electron microscope (FE-SEM), zeta-sizer, zeta-potential, differential scanning calorimetry (DSC) and Fourier transform infrared (FT-IR) spectrometry. In vitro drug release study was performed in phosphate buffered saline (PBS) with or without 0.5% (w/v) Tween 80 for 24h. Cellular uptake was studied at time intervals of 0.5, 1, and 2h in MCF-7 cells, and cell growth inhibition study was performed for 24h using MCF-7 cells (cancer cells), and HaCaT cells (normal cells). Three different types of PTX-NCs with a mean size of 236.0±100.6nm (PTX-NC), 302.0±152.0nm (Tf-PTX-NC) and 339±180.6nm (HA-PTX-NC) were successfully prepared. The drug release profiles showed 29.1%/6.9% (PTX (pure)), 40.7%/23.9% (PTX-NC), 50.5%/25.1% (Tf-PTX-NC) and 46.8/24.8% (HA-PTX-NC) in PBS with/without 0.5% (w/v) Tween 80 for 24h, respectively. As per the results, the drug release of PTX-NCs showed the faster release as compared to that of PTX (pure). Surface modified PTX-NCs exhibited higher values for cell permeability than unmodified PTX-NC in the cellular uptake study. Surface modified PTX-NCs inhibited the cell growth approximately to 60% in MCF-7 cells, however effect of surface modified PTX-NCs on normal cell line was lower than the PTX-NC and PTX (pure). In conclusion, biological macromolecules (Tf or HA) surface modified PTX-NC enhanced the cellular uptake and the cell growth inhibition.

Abstract
The rationale of this study was to improve the stability, cellular uptake, and evaluate the cytotoxicity of surface modified curcumin nanoparticles (CUR NP). CUR NP were surface modified with proteins (transferrin [Tf] and gelatin [GT]) by adsorption to improve their stability and targeting property. CUR NP were evaluated for stability, in vitro drug release, cellular uptake and cell cytotoxicity. The particle sizes of CUR NP were 153.2±56.4nm (CUR NP), 145.0±26.8nm (Tf-CUR NP), and 167.7±42.7nm (GT-CUR NP). The stabilities of Tf-CUR NP and GT-CUR NP were higher than that of CUR NP. Tf-CUR NP and GT-CUR NP showed faster drug release than those shown by CUR NP and CUR (pure) in pH 7.4 PBS and cell media (RPMI) for 36h. The cellular uptake and cytotoxicity of Tf- and GT-modified CUR NP were higher than those of CUR NP in MCF-7 and A549 cells. In conclusion, Tf-CUR NP and GT-CUR NP exhibited improved stability, enhanced cellular uptake, and stronger cytotoxicity.
