Yang C, Liu P. Regulating Drug Release Performance of Acid-Triggered Dimeric Prodrug-Based Drug Self-Delivery System by Altering Its Aggregation Structure. Molecules 2024; 29:3619. [PMID: 39125024 PMCID: PMC11313937 DOI: 10.3390/molecules29153619] [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: 06/17/2024] [Revised: 07/24/2024] [Accepted: 07/26/2024] [Indexed: 08/12/2024] Open
Abstract
Dimeric prodrugs have been investigated intensely as carrier-free drug self-delivery systems (DSDSs) in recent decades, and their stimuli-responsive drug release has usually been controlled by the conjugations between the drug molecules, including the stimuli (pH or redox) and responsive sensitivity. Here, an acid-triggered dimeric prodrug of doxorubicin (DOX) was synthesized by conjugating two DOX molecules with an acid-labile ketal linker. It possessed high drug content near the pure drug, while the premature drug leakage in blood circulation was efficiently suppressed. Furthermore, its aggregation structures were controlled by fabricating nanomedicines via different approaches, such as fast precipitation and slow self-assembly, to regulate the drug release performance. Such findings are expected to enable better anti-tumor efficacy with the desired drug release rate, beyond the molecular structure of the dimeric prodrug.

Abstract
Even though the reversal of multi-drug resistance (MDR) by numerous nanoparticles has been extensively studied, limited success has been achieved. To overcome this barrier, we report a rationally-designed pH-sensitive micelle, in which doxorubicin (Dox) and resveratrol (Res) were co-loaded. The micelle was based on methoxy poly (ethylene glycol)-poly(d,l-lactide)-poly(l-histidine) (mPEG-PLA-PHis), which integrated passive targeting, endo-lysosomal escape and pH-responsive payloads release. At a physiological pH of 7.4 (slightly alkali), Dox and Res were incorporated into the micelles core using the thin-film hydration method (pH-endoSM/Dox/Res). After cellular uptake, the micelles exhibited an enhanced dissociation in response to the acidic endosomes, triggering the release of Res and Dox. Furthermore, Res was observed to synergistically improve the cytotoxicity of Dox by down-regulating the P-glycoprotein (P-gp) expression, decreasing the membrane potential of the mitochondrial and ATP level, as well as inducing cell apoptosis mediated by mitochondria. The pH-endoSM/Dox/Res showed a prominent ability to decrease the IC50 of Dox by a factor of 17.38 in cell cytotoxicity against the MCF-7/ADR cell line. In vivo distribution demonstrated the excellent tumor-targeting ability of the pH-endoSM/Dox/Res. All results indicated that pH-endoSM/Dox/Res held great potential for the treatment of Dox-resistance breast cancer cells.

Abstract
A novel niosomal delivery system was designed and investigated for the targeted delivery of daunorubicin (DNR) against acute myeloid leukemia (AML). Anti-CD123 antibodies conjugated to Mal-PEG2000-DSPE were incorporated into normal niosomes (NS) via a post insertion method to afford antibody-modified niosomes (CD123-NS). Next, NS was modified with varying densities of antibody (0.5 or 2%, antibody/Span 80, molar ratio), thus providing L-CD123-NS and H-CD123-NS. We studied the effect of antibody density on the uptake efficiency of niosomes in NB4 and THP-1 cells, on which CD123 express differently. Our results demonstrate CD123-NS showed significantly higher uptake efficiency than NS in AML cells, and the uptake efficiency of CD123-NS has been ligand density-dependent. Also, AML cells preincubated with anti-CD123 antibody showed significantly reduced cellular uptake of CD123-NS compared to control. Further study on the uptake mechanism confirmed a receptor-mediated endocytic process. Daunorubicin (DNR)-loaded H-CD123-NS demonstrated a 2.45- and 3.22-fold higher cytotoxicity, compared to DNR-loaded NS in NB4 and THP-1 cells, respectively. Prolonged survival time were observed in leukemic mice treated with DNR-H-CD123-NS. Collectively, these findings support that the CD123-NS represent a promising delivery system for the treatment of AML.

Abstract
Nanomedicine has advanced to clinical trials for adult cancer therapy. However, the field is still in its infancy for treatment of childhood malignancies such as acute lymphoblastic leukemia (ALL). Nanotherapy offers multiple advantages over conventional therapy. It facilitates targeted delivery and enables controlled release of drugs to reduce treatment-related side effects. Here, we demonstrate that doxorubicin (DOX) encapsulated in polymeric nanoparticles (NPs) modified with targeting ligands against CD19 (CD19-DOX-NPs) can be delivered in a CD19-specific manner to leukemic cells. The CD19-DOX-NPs were internalized via receptor-mediated endocytosis and imparted cytotoxicity in a CD19-dependent manner in CD19-positive ALL cells. Leukemic mice treated with CD19-DOX-NPs survived significantly longer and manifested a higher degree of agility, indicating reduced apparent systemic toxicity during treatment compared to mice treated with free DOX. We suggest that targeted delivery of drugs used in childhood cancer treatment should improve therapeutic efficacy and reduce treatment-related side effects in children.

Abstract
Three-dimensional (3D) tissue-engineered tumor models have the potential to bridge the gap between monolayer cultures and patient-derived xenografts for the testing of nanoparticle (NP)-based cancer therapeutics. In this study, a hydrogel-derived prostate cancer (PCa) model was developed for the in vitro evaluation of doxorubicin (Dox)-loaded polymer NPs (Dox-NPs). The hydrogels were synthesized using chemically modified hyaluronic acid (HA) carrying acrylate groups (HA-AC) or reactive thiols (HA-SH). The crosslinked hydrogel networks exhibited an estimated pore size of 70-100 nm, similar to the spacing of the extracellular matrices (ECM) surrounding tumor tissues. LNCaP PCa cells entrapped in the HA matrices formed distinct tumor-like multicellular aggregates with an average diameter of 50 μm after 7 days of culture. Compared to cells grown on two-dimensional (2D) tissue culture plates, cells from the engineered tumoroids expressed significantly higher levels of multidrug resistance (MDR) proteins, including multidrug resistance protein 1 (MRP1) and lung resistance-related protein (LRP), both at the mRNA and the protein levels. Separately, Dox-NPs with an average diameter of 54 ± 1 nm were prepared from amphiphilic block copolymers based on poly(ethylene glycol) (PEG) and poly(ε-caprolactone) (PCL) bearing pendant cyclic ketals. Dox-NPs were able to diffuse through the hydrogel matrices, penetrate into the tumoroid and be internalized by LNCaP PCa cells through caveolae-mediated endocytosis and macropinocytosis pathways. Compared to 2D cultures, LNCaP PCa cells cultured as multicellular aggregates in HA hydrogel were more resistant to Dox and Dox-NPs treatments. Moreover, the NP-based Dox formulation could bypass the drug efflux function of MRP1, thereby partially reversing the resistance to free Dox in 3D cultures. Overall, the engineered tumor model has the potential to provide predictable results on the efficacy of NP-based cancer therapeutics.

Abstract
Lipases can be efficiently entrapped in the pores of hydrophobic silicates by a simple and cheap sol-gel process in which a mixture of a hydrophobic alkylsilane RSi(OCH3)3 and Si(OCH3)4 is hydrolyzed under basic conditions in the presence of the enzyme. Additives such as isopropanol, polyvinyl alcohol, cyclodextrins, ionic liquids or surfactants enhance the efficiency of this type of lipase-immobilization. The main area of application of these heterogeneous biocatalysts concerns esterification or transesterification in organic solvents, ionic liquids, or supercritical carbon dioxide. Rate enhancements (relative to the traditional use of lipase powders) of several orders of magnitude have been observed, in addition to higher thermal stability. The lipase-immobilizates are particularly useful in the kinetic resolution of chiral esters, enantioselectivity often being higher than what is observed when using the commercial forms of these lipases (powder or classical immobilizates). Thus, due to the low price of sol-gel entrapment, the excellent performance of the lipase-immobilizates, and the ready recyclability, the method is industrially viable.

Abstract
Small molecule chemotherapeutics often have undesired physiochemical and pharmacological properties, such as low solubility, severe side effect and narrow therapeutic index. To address these challenges, polymeric nanomedicine drug delivery technology has been routinely employed, in particular with the use of biodegradable and biocompatible polyesters, such as poly(lactide) (PLA) and poly(lactide-co-glycolide) (PLGA). Here we review the development and use of PLA and PLGA for the delivery of chemotherapeutic agents in the forms of polymer-drug conjugates and nanoconjugates.

Abstract
A unique method that applied a multilayer-immobilization strategy was developed to prepare nanofibrous enzymes for biosynthesis. LiCl co-electrospun with polyurethane nanofibers enabled strong physical adsorption of bovine serum albumin (BSA), forming the first layer of protein on the nanofibers; lipase AK was subsequently crosslinked to BSA as an outer layer of enzyme. The content of LiCl in nanofibers was found to be a sensitive factor affecting the activity and stability of the immobilized lipase. For biodiesel synthesis from soybean oil and methanol in isooctane, the reaction rate catalyzed by nanofibrious lipase carrying 5 wt% LiCl was 6.6-fold higher than fibers without LiCl, with a conversion of 91% was achieved within 2 h. LiCl also induced much improved enzyme stability. The nanofibrous lipase with 5% LiCl could be repeatedly used for 42 cycles without apparent activity loss, while the immobilized lipase without LiCl lost over 90% activity within 13 reuse cycles.

Abstract
Introduction. Treatment of breast cancer includes surgery, drugs (hormone therapy and chemotherapy), and radiation. A discussion of eight drug constructs for the treatment of breast cancer, derived through application of in silico optimized molecular properties and substituent substitution, are analyzed using pattern recognition techniques. Methods and Materials. Determined properties of these eight compounds (inclusive of doxorubicin) showed a Log P varying from 0.567 to 4.137, rotatable bonds from 5 to 12, polar surface area from 195.1 A2 to 206.1 A2, and water solubility from 0.00873 mg/L to 390 mg/L. Analysis of similarity (ANOSIM), hierarchical cluster analysis, and neighbor-joining cluster analysis elucidated relationships among the drugs that are useful for pharmaceutical consideration. Results and Discussion. Although the new derivatives share the same parent scaffold (doxorubicin), elucidation by analysis of similarity (ANOSIM) indicates that these assorted compounds are substantially distinct. The number of oxygen and nitrogen atoms (hydrogen bond acceptors) remained constant at 12 for compounds. Although violations of the Rule of five remained constant at three for all compounds, the variation of Log P and water solubility offers potentially beneficial medicinal activity for this group of anticancer agents that may enhance the antitumor activity of these anthracycline antibiotics. Hierarchical cluster analysis results clearly differentiated the parent doxorubicin from all higher molecular weight analogs. This outcome is confirmed with the use of neighbor-joining cluster analysis. Conclusion. By utilizing in silico optimization with pattern recognition analysis, potentially advantageous analogs can be elucidated from known effective pharmaceuticals.

Abstract
We report here a unique method for formulating doxorubicin-polylactide (Doxo-PLA) conjugate nanoparticles, known as nanoconjugates (NCs), through Doxo/(BDI)ZnN(TMS)(2)-mediated [(BDI) = 2-((2,6-diisopropylphenyl)amido)-4-((2,6-diisopropylphenyl)-imino)-2-pentene], chemo- and regioselective polymerizations of lactide (LA) followed by nanoprecipitation. When Doxo/(BDI)ZnN(TMS)(2) was mixed with 1-pyrenemethanol (Pyr-OH) and 1-pyrenemethylamine (Pyr-NH(2)) and the mixture was utilized for the polymerization of LA, remarkable chemoselectivity was observed. Pyr-OH was completely consumed and covalently linked to the terminus of the PLA, whereas the Pyr-NH(2) remained intact in the polymerization solution. When Doxo was used as the initiator to polymerize LA in the presence of (BDI)ZnN(TMS)(2), the polymerization was complete within hours, with nearly 100% Doxo-loading efficiency and 100% LA conversion. Doxo loading as high as 27% could be achieved at a LA/Doxo ratio of 10. Both the steric bulk of the chelating ligand and the metal catalyst had dramatic effects on the regioselectivity during the initiation step. When Doxo/(BDI)ZnN(TMS)(2) was mixed with succinic anhydride (SA) to mimic the initiation of Doxo/(BDI)ZnN(TMS)(2)-mediated LA polymerization, Doxo-14-succinic ester (Doxo-SE) was the predominate product. When the steric bulk of BDI was reduced or when the BDI ligand was removed, significant amounts of Doxo-4',14-bis-succinic ester (Doxo-2SE) and Doxo-4',9,14-trisuccinic ester (Doxo-3SE) were formed. The use of (BDI)MgN(TMS)(2) in such a reaction also resulted in reduced regioselectivity and formation of both Doxo-SE and Doxo-2SE. Doxo/(BDI)ZnN(TMS)(2)-mediated LA polymerizations yielded Doxo-PLA conjugates with well-controlled molecular weights and polydispersities (as low as 1.02). The nanoprecipitation of Doxo-PLA formed NCs less than 150 nm in size with narrow particle size distributions. The sustained release of Doxo from Doxo-PLA NCs was achieved without a burst release. This method may have widespread utility for controlled conjugation of hydroxyl-containing agents to polyesters and formation of corresponding nanoparticles.

Abstract
A protein solubilization method has been developed to directly solubilize protein clusters into organic solvents containing small quantities of surfactant and trace amounts of water. Termed "direct solubilization," this technique was shown to solubilize three distinct proteins - subtilisin Carlsberg, lipase B from Candida antarctica, and soybean peroxidase - with much greater efficiencies than extraction of the protein from aqueous solution into surfactant-containing organic solvents (referred to as extraction). More significant, however, was the dramatic increase in directly solubilized enzyme activity relative to extracted enzyme activity, particularly for subtilisin and lipase in polar organic solvents. For example, in THF the initial rate towards bergenin transesterification was ca. 70 times higher for directly solubilized subtilisin than for the extracted enzyme. Furthermore, unlike their extracted counterparts, the directly solubilized enzymes yielded high product conversions across a spectrum of non-polar and polar solvents. Structural characterization of the solubilized enzymes via light scattering and atomic force microscopy revealed soluble proteins consisting of active enzyme aggregates containing approximately 60 and 100 protein molecules, respectively, for subtilisin and lipase. Formation of such clusters appears to provide a microenvironment conducive to catalysis and, in polar organic solvents at least, may protect the enzyme from solvent-induced inactivation.

Abstract
A combinatorial experimental technique was used to identify salts and salt mixtures capable of activating penicillin amidase in organic solvents for the transesterification of phenoxyacetate methyl ester with 1-propanol. Penicillin amidase was lyophilized in the presence of various chloride and acetate salts within 96-deep-well plates and catalytic rates measured to determine lead candidates for highly salt-activated preparations. The kinetics of the most active formulations were then further evaluated. These studies revealed that a formulation consisting of 98% (w/w) of a 1:1 KAc:CsCl salt mixture, 1% (w/w) enzyme, and 1% (w/w) potassium phosphate buffer was approximately 35,000-fold more active than the salt-free formulation in hexane, as reflected in values of V(max)/K(m). This extraordinary activation could be extended to more polar solvents, including tert-amyl alcohol, and to formulations with lower total salt contents. A correlation was found between the kosmotropic/chaotropic behavior of the salts (as measured by the Jones-Dole B coefficients) and the observed activation. Strongly chaotropic cations combined with strongly kosmotropic anions yielded the greatest activation, and this is likely due to the influence of the ions on protein-water and protein-salt interactions.

Abstract
Enzyme catalysis in low water containing organic solvents is finding an increasing number of applications in diverse areas. This review focuses on some aspects which have not been reviewed elsewhere. Different strategies for obtaining higher activity and stability in such media are described. In this context, the damaging role of lyophilization and the means of overcoming such effects are discussed. Ultrasonication and microwave assistance are two emerging approaches for enhancing reaction rates in low water media. Control of water activity and medium engineering are two crucial approaches in optimization of catalytic behaviour in nonaqueous enzymology. Organometallics and synthesis/modification of polymers are two areas where nonaqueous enzymology can play a greater role in the coming years. The greater understanding of enzyme behaviour in nonaqueous media is expected to lead to larger and even more diverse kinds of applications.

Abstract
Highly active enzyme formulations can be prepared for use in nonaqueous media. Considerable progress has been made in the past two years on gaining an improved mechanistic understanding of enzyme function and activation in dehydrated environments. This increased fundamental understanding has led to the development of a broad array of techniques for generating active, stable, and enantioselective and regioselective tailored enzymes for synthetically relevant transformations. This, in turn, is resulting in an exponential increase in the opportunities for enzymatic processes to be developed on a commercial scale.
