Abstract
Nanomedicine holds promise for potentiating drug combination therapies. Increasing (pre)clinical evidence is available exemplifying the value of co-formulating and co-delivering different drugs in modular nanocarriers. Taxanes like paclitaxel (PTX) are widely used anticancer agents, and commonly combined with corticosteroids like dexamethasone (DEX), which besides for suppressing inflammation and infusion reactions, are increasingly explored for modulating the tumor microenvironment towards enhanced nano-chemotherapy delivery and efficacy. We here set out to develop a size- and release rate-tunable polymeric micelle platform for co-delivery of taxanes and corticosteroids. We synthesized amphiphilic mPEG-b-p(HPMAm-Bz) block copolymers of various molecular weights and used them to prepare PTX and DEX single- and double-loaded micelles of different sizes. Both drugs could be efficiently co-encapsulated, and systematic comparison between single- and co-loaded formulations demonstrated comparable physicochemical properties, encapsulation efficiencies, and release profiles. Larger micelles showed slower drug release, and DEX release was always faster than PTX. The versatility of the platform was exemplified by co-encapsulating two additional taxane-corticosteroid combinations, demonstrating that drug hydrophobicity and molecular weight are key properties that strongly contribute to drug retention in micelles. Altogether, our work shows that mPEG-b-p(HPMAm-Bz) polymeric micelles serve as a tunable and versatile nanoparticle platform for controlled co-delivery of taxanes and corticosteroids, thereby paving the way for using these micelles as a modular carrier for multidrug nanomedicine.

Abstract
Antibacterial resistance requires an advanced strategy to increase the efficacy of current therapeutics in addition to the synthesis of new generations of antibiotics. In this study, copper oxide nanoparticles (CuO-NPs) were green synthesized using Moringa oleifera root extract. CuO-NPs fabricated into a form of aspartic acid-ciprofloxacin-polyethylene glycol coated copper oxide-nanotherapeutics (CIP-PEG-CuO) to improve the antibacterial activity of NPs and the efficacy of the drug with controlled cytotoxicity. These NPs were charachterized by Fourier transform infrared spectroscopy (FTIR), x-rays diffraction spectroscopy (XRD), scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). Antibacterial screening and bacterial chemotaxis investigations demonstrated that CIP-PEG-CuO NPs show enhanced antibacterial potential against Gram-positive and Gram-negative clinically isolated pathogenic bacterial strains as compared to CuO-NPs. In ex-vivo cytotoxicity CIP-PEG-CuO-nano-formulates revealed 88% viability of Baby Hamster Kidney 21 cell lines and 90% RBCs remained intact with nano-formulations during hemolysis assay. An in-vivo studies on animal models show that Staphylococcus aureus were eradicated by this newly developed formulate from the infected skin and showed wound-healing properties. By using specially designed nanoparticles that are engineered to precisely transport antimicrobial agents, these efficient nano-drug delivery systems can target localized infections, ensure targeted delivery, enhance efficacy through increased drug penetration through physical barriers, and reduce systemic side effects for more effective treatment.

Abstract
A response surface methodology based on the Box-Behnken design was employed to develop fucoxanthin (FX) delivery nanocarrier from alginate (ALG) and chitosan (CS). The FX-loaded ALG/CS nanoparticles (FX-ALG/CS-NPs) were fabricated using oil-in-water emulsification and ionic gelation. The optimal formulation consisted of an ALG:CS mass ratio of 0.015:1, 0.71 % w/v Tween™ 80, and 5 mg/mL FX concentrations. The resulting FX-ALG/CS-NPs had a size of 227 ± 23 nm, a zeta potential of 35.3 ± 1.7 mV, and an encapsulation efficiency of 81.2 ± 2.8 %. These nanoparticles exhibited enhanced stability under simulated environmental conditions and controlled FX release in simulated gastrointestinal fluids. Furthermore, FX-ALG/CS-NPs showed increased in vitro oral bioaccessibility, gastrointestinal stability, antioxidant activity, anti-inflammatory effect, and cytotoxicity against various cancer cells. The findings suggest that ALG/CS-NPs are effective nanocarriers for the delivery of FX in nutraceuticals, functional foods, and pharmaceuticals.

Abstract
The objective of this study was to develop folic acid (FA) grafted mixed polymeric micelles loaded with Tamoxifen citrate (TMXC) to enhance its antitumor activity in breast tissues. The conjugated folic acid Pluronic 123 (FA-P123) was prepared using carbonyl diimidazole cross-linker chemistry and confirmed using FTIR and 1HNMR. TMXC-loaded P123/P84 (unconjugated) and TMXC-loaded FA-P123/P84 (conjugated) micelles were examined for encapsulation efficiency, particle size, surface charge, in vitro drug release, cytotoxic effect, and cellular uptake by a breast cancer cell line. The conjugated TMXC-loaded micelle exhibited a nanoparticle size of 35.01 ± 1.20 nm, a surface charge of-20.50 ± 0.95 mV, entrapped 87.83 ± 5.10% and released 67.58 ± 2.47% of TMXC after 36 h. The conjugated micelles exhibited a significantly higher cellular uptake of TMXC by the MCF-7 cell line and improved in vitro cytotoxicity by 2.48 folds compared to the TMXC-loaded unconjugated micelles. The results of in vivo studies indicated that TMXC-loaded FA-P123/P84 has a potential antitumor activity, as revealed by a significant reduction of tumor volume in tumor-bearing mice compared to TMXC-loaded unconjugated micelles. In conclusion, the obtained results suggested that conjugated FA-P123/P84 micelles could be an encouraging carrier for the treatment of breast cancer with TMXC.

A comparative study of the predictive performance of different descriptor calculation tools: Molecular-based elution order modeling and interpretation of retention mechanism for isomeric compounds from METLIN database. J Chromatogr A 2024; 1719:464731. [PMID: 38377661 DOI: 10.1016/j.chroma.2024.464731] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 02/08/2024] [Accepted: 02/09/2024] [Indexed: 02/22/2024]
Abstract
In the pharmaceutical industry, the need for analytical standards is a bottleneck for comprehensive evaluation and quality control of intermediate and end products. These are complex mixtures containing structurally related molecules. In this regard, chromatographic peak annotation, especially for critical pairs of isomers and closest structural analogs, can be supported by using a Quantitative Structure Retention Relationship (QSRR) approach. In our study, we investigated the fundamental basis of the reversed-phase (RP) retention mechanism for 1141 isomeric compounds from the METLIN SMRT dataset. Nine different descriptor calculation tools combined with different feature selection methods (genetic algorithm (GA), stepwise, Boruta) and machine learning (ML) approaches (support vector machine (SVM), multiple linear regression (MLR), random forest (RF), XGBoost) were applied to provide a reliable molecular structure-based interpretation of RP retention behaviour of the isomeric compounds. Strict internal and external validation metrics were used to select models with the best predictive capabilities (rtest > 0.73, order of elution > 60 %). For the developed models, mean absolute errors were in the range of 60 to 110 s. Stepwise and GA showed the most suitable performance as descriptor selection methods, while SVM and XGBoost modeling gave satisfactory predictive characteristics in most cases. Validation performed on the published experimental data for structurally related pharmaceutical compounds confirmed the best accuracy of MLR modeling in combination with GA feature selection of general physico-chemical properties. The resulting models will be useful for the prediction of separation and identification of structurally related compounds in pharmaceutical analysis, providing a simultaneous understanding of the interaction mechanisms leading to their retention under RP conditions.

Abstract
The primary objective of this paper is to serve as a comprehensive study on the synthesis of stimulus-sensitive micelles based on polysaccharides. In pursuit of this goal, functionalization with polylactide (PLA) was used as the water-resistance part and poly[2(Dimethyl amino)ethyl methacrylate] (PDMAEMA) or poly(methacrylic acid) (PMA) were employed as the stimulus-sensitive part to create micelles with a simple structure. FTIR and 1HNMR measurements were utilized to characterize the functionalized polysaccharides. Fluorescence spectroscopy was used to determine the critical micelle concentration. The average micelles' diameter, as observed in SEM and TEM pictures, ranges from 50 to 200 nm. To gain a better understanding of the potential of theses micelles for delivering drugs in a stimulus-sensitive manner, drug release tests were conducted. The cytotoxicity of these nano-vehicles was examined using the MTT assay. Utilizing MCF7 cells stained with DAPI and Mito Tracker, cellular uptake studies were also investigated. The results indicate that the behavior of the micelles is nearly same even though they used polysaccharides with various charge densities or different stimulus sensitive polymers. This approach, therefore, demonstrates that a broad range of micelle production is possible by employing diverse polysaccharides functionalized with PLA and polymethacrylates.

Abstract
Despite various treatment modalities for breast cancer, it still persists as one of the most diagnosed types of cancer in females. The recent investigations in the epigenetics of breast cancer reveal several aberrations in the expression levels of various HDAC enzymes. Henceforth, the present work entails the formulation and characterization of a lipid polymer-based hybrid nanoparticulate (LPN) system for delivery of an epigenetic modulator drug, Belinostat, for its clinical application in breast cancer. The size of Belinostat nanoparticles prepared using a modified hot homogenization method was found to be 166.6 ± 19.95 nm with an encapsulation efficiency of 94.5 ± 5.1%. In vitro characterization for cytotoxicity, cellular uptake, and protein expression in two different breast cancer cells, 4T1 and MCF 7, revealed the superiority of the formulation in comparison with the free drug in MCF 7 cells. Subsequently, the behaviour of the formulation in in vivo settings of healthy and breast cancer xenograft bearing animals was analyzed using pharmacokinetic and biodistribution studies. The results revealed that the formulation demonstrated multi-fold improvement in the pharmacokinetic parameters in tumor bearing animals when compared with the free drug while no difference in pharmacokinetic behaviour was observed in healthy animals indicating the altered biodistribution and specificity of the formulation in breast tumor. This was confirmed by the biodistribution studies exhibiting 20-fold improved uptake and retention of the nanoparticulate formulation in tumor tissues of the animal model at the end of 4 h. Thus, the developed LPN system holds potential to act as a novel drug delivery system for Belinostat with several advantages over the free drug.

Abstract
Polymeric micelles are among the most extensively used drug delivery systems. Key properties of micelles, such as size, size distribution, drug loading, and drug release kinetics, are crucial for proper therapeutic performance. Whether polymers from more controlled polymerization methods produce micelles with more favorable properties remains elusive. To address this question, we synthesized methoxy poly(ethylene glycol)-b-(N-(2-benzoyloxypropyl)methacrylamide) (mPEG-b-p(HPMAm-Bz)) block copolymers of three different comparable molecular weights (∼9, 13, and 20 kDa), via both conventional free radical (FR) and reversible addition-fragmentation chain transfer (RAFT) polymerization. The polymers were subsequently employed to prepare empty and paclitaxel-loaded micelles. While FR polymers had relatively high dispersities (Đ ∼ 1.5-1.7) compared to their RAFT counterparts (Đ ∼ 1.1-1.3), they formed micelles with similar pharmaceutical properties (e.g., size, size distribution, critical micelle concentration, cytotoxicity, and drug loading and retention). Our findings suggest that pharmaceutical properties of mPEG-b-p(HPMAm-Bz) micelles do not depend on the synthesis route of their constituent polymers.

Abstract
Since tumor stroma poses as a barrier to achieve efficacy of nanomedicines, it is essential to evaluate nano-chemotherapeutics in stroma-mimicking 3D models that reliably predict their behavior regarding these hurdles limiting efficacy. In this study, we evaluated the effect of paclitaxel-loaded polymeric micelles (PTX-PMCs) and polymeric nanoparticles (PTX-PNPs) in a tumor stroma-mimicking 3D in vitro model. PTX-PMCs (77 nm) based on a amphiphilic block copolymer of mPEG-b-p(HPMAm-Bz) and PTX-PNPs (159 nm) based on poly(lactic-co-glycolic acid) were prepared, which had an encapsulation efficiency (EE%) of 81 ± 15% and 45 ± 8%, respectively. 3D homospheroids of mouse 4T1 breast cancer cells and heterospheroids of NIH3T3 fibroblasts and 4T1 (5:1 ratio) were prepared and characterized with high content two-photon microscopy and immunostaining. Data showed an induction of epithelial-mesenchymal transition (α-SMA) in both homo- and heterospheroids, while ECM (collagen) deposition only in heterospheroids. Two-photon imaging revealed that both fluorescently labeled PMCs and PNPs penetrated into the core of homospheroids and only PMCs penetrated into heterospheroids. Furthermore, PTX-PMCs, PTX-PNPs, and free PTX induced cytotoxicity in tumor cells and fibroblasts grown as monolayer, but these effects were substantially reduced in 3D models, in particular in heterospheroids. Gene expression analysis showed that heterospheroids had a significant increase of drug resistance markers (Bcl2, Abgc2) compared to 2D or 3D monocultures. Altogether, this study shows that the efficacy of nanotherapeutics is challenged by stroma-induced poor penetration and development of resistant phenotype. Therefore, this tumor stroma-mimicking 3D model can provide an excellent platform to study penetration and effects of nanotherapeutics before in vivo studies.

Abstract
Triptolide (as an effective antitumor drug) is limited in clinical application because of its poor solubility and absorption in-vivo. Herein, we prepared folic acid modified polymer micelles to encapsulate triptolide and enhance its biologicalavailability coupled with antitumor
effect. We prepared nano-micelles of triptolide through thin lipid film hydrational method. Physical properties and in vitro release characterization of Fol-Plla-cl-Peg-Plla-cl-Tmicelles were evaluated, while bioavailability of the formulation in rats was investigated. Tumor targeting
potential of micelles was determined by observing the uptake of A549 cells. In-Vitro antitumor activity of micelles and free triptolide (API) was investigated with MTT assay. The prepared polymer material exhibited no cytotoxicity. The particle size distribution of Fol-Plla-cl-Peg-Plla-cl-T
micelles was uniform and small, with good stability and high efficiency of entrapment. Triptolide In-Vitro release from micelles demonstrated slow and continuous released for 24 h. Compared with API, the half-life of micelles was prolonged, whilst its bioavailability in-vivo
was increased by about 6.35 times. More importantly, Fol-Plla-cl-Peg-Plla-cl-T micelles significantly improved the antitumor activity of triptolide and showed good tumor targeting potential. Fol-Plla-cl-Peg-Plla-cl-T micelles could improve the bioavailability and antitumor activity of triptolide,
amid demonstration of good tumor targeting and high safety.

J Control Release 2022; 349:954-962. [PMID: 35931210 DOI: 10.1016/j.jconrel.2022.07.044] [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: 06/10/2022] [Revised: 07/22/2022] [Accepted: 07/31/2022] [Indexed: 11/16/2022]
Abstract
To improve the reliability of in vitro release studies of drug delivery systems, we developed a novel in vitro method for the evaluation of drug release from polymeric micelles in complex biological media. Polymeric micelles based on poly(N-2-hydroxypropyl methacrylamide)-block-poly(N-2-benzoyloxypropyl methacrylamide) (p(HPMAm)-b-p(HPMAm-Bz)) of which 10% of the chains was functionalized with biotin at the p(HPMAm) terminus were prepared using a solvent extraction method. The size of the micelles when loaded with a hydrophobic agent, namely paclitaxel (a clinically used cytostatic drug) or curcumin (a compound with multiple pharmacological activities), was around 65 nm. The biotin decoration allowed the binding of the micelles to streptavidin-coated magnetic beads which occurred within 10 min and reached a binding efficiency of 90 ± 6%. Drug release in different media was studied after the magnetic separation of micelles bound to the streptavidin-coated beads, by determination of the released drug in the media as well as the retained drug in the micellar fraction bound to the beads. The in vitro release of paclitaxel and curcumin at 37 °C in PBS, PBS containing 2% v/v Tween 80, PBS containing 4.5% w/v bovine serum albumin, mouse plasma, and whole mouse blood was highly medium-dependent. In all media studied, paclitaxel showed superior micellar retention compared to curcumin. Importantly, the presence of serum proteins accelerated the release of both paclitaxel and curcumin. The results presented in this study show great potential for predicting drug release from nanomedicines in biological media which in turn is crucial for their further pharmaceutical development.
