Implementing losartan potassium-laden pegylated nanocubic vesicles as a novel nanoplatform to alleviate cisplatin-induced nephrotoxicity via blocking apoptosis and activating the wnt/β-catenin/TCF-4 pathway. Life Sci 2024; 354:122955. [PMID: 39122109 DOI: 10.1016/j.lfs.2024.122955] [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: 04/21/2024] [Revised: 07/16/2024] [Accepted: 08/05/2024] [Indexed: 08/12/2024]
Abstract
AIMS Losartan potassium-laden pegylated nanocubic vesicles (LP-NCVs-PEG) have an intriguing kidney-targeted nanoplatform for acute renal injury via blocking apoptosis and activating wnt/β-catenin pathway. MAIN METHODS Utilizing a thin-film hydration methodology established on 42 full factorial design to produce LP loaded nanocubic formulations (LP-NCVs) which composed mainly from L-α-phosphatidylcholine and poloxamer. The optimization process was designed to select the formulation with maximum entrapment efficiency (EE %), maximum in-vitro drug release (Q8h), and minimum vesicle size (VS). The optimum formulation was then pegylated to obtain LP-NCVs-PEG formulation that shields NCVs from the harsh ecosystem of the stomach, improves their oral drug delivery performance and targets the proximal renal tubules with no systemic toxicity. Male albino rats were injected with Cisplatin (6 mg/kg, i.p.) alone or with LP-formulations (5 mg/kg/day). Kidney injury markers, inflammatory markers, apoptotic markers. Besides renal tissue expression of Wnt, β-Catenin, GSK-3β, renal RNA gene expression of TCF-4, LEF-1 and histopathology were also analyzed to display pharmacological study. KEY FINDINGS The pharmacokinetics studies demonstrated that LP-NCVs-PEG boosted LP bioavailability approximately 3.61 times compared to LP oral solution. Besides LP-NCVs-PEG may have an intriguing kidney-targeted nanoplatform for acute renal injury via decreased renal toxicity markers, renal expression of LEF-1, GSK3-β, caspase, TNF-α, NF-κB and TUNEL expression. Alternatively, increased renal tissue level of Bcl-2, wnt, β-catenin and TCF-4. SIGNIFICANCE LP-NCVs-PEG improved LP pharmacokinetics targeting the kidney and improved injury by activating wnt/β-catenin/TCF-4 pathway, blocking apoptosis, inflammation and renal toxicity markers suggesting it might be successful nephroprotective adjuvant therapy.

[PMID: 39246659 PMCID: PMC11377347 DOI: 10.3389/fphar.2024.1433734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2024] [Accepted: 08/06/2024] [Indexed: 09/10/2024] Open
Abstract
Introduction The study aimed to systematically enhance the fabrication process of flurbiprofen-loaded bilosomes (FSB) using Quality by Design (QbD) principles and Design of Experiments (DOE). The objective was to develop an optimized formulation with improved entrapment efficiency and targeted drug delivery capabilities. Methods The optimization process involved applying QbD principles and DOE to achieve the desired formulation characteristics. Superparamagnetic iron oxide nanoparticles (SPIONs) were incorporated to impart magnetic responsiveness. The size, entrapment efficiency, morphology, and in vitro release patterns of the FSB formulation were evaluated. Additionally, an in situ forming hydrogel incorporating FSB was developed, with its gelation time and drug release kinetics assessed. In vivo studies were conducted on osteoarthritic rats to evaluate the efficacy of the FSB-loaded hydrogel. Results The optimized FSB formulation yielded particles with a size of 453.60 nm and an entrapment efficiency of 91.57%. The incorporation of SPIONs enhanced magnetic responsiveness. Morphological evaluations and in vitro release studies confirmed the structural integrity and sustained release characteristics of the FSB formulation. The in situ forming hydrogel exhibited a rapid gelation time of approximately 40 ± 1.8 s and controlled drug release kinetics. In vivo studies demonstrated a 27.83% reduction in joint inflammation and an 85% improvement in locomotor activity in osteoarthritic rats treated with FSB-loaded hydrogel. Discussion This comprehensive investigation highlights the potential of FSB as a promising targeted drug delivery system for the effective management of osteoarthritis. The use of QbD and DOE in the formulation process, along with the integration of SPIONs, resulted in an optimized FSB formulation with enhanced entrapment efficiency and targeted delivery capabilities. The in situ forming hydrogel further supported the formulation's applicability for injectable applications, providing rapid gelation and sustained drug release. The in vivo results corroborate the formulation's efficacy, underscoring its potential for improving the treatment of osteoarthritis.

A poly-δ-decalactone (PDL) based nanoemulgel for topical delivery of ketoconazole and eugenol against Candida albicans. NANOSCALE ADVANCES 2024:d4na00176a.

Abstract
This study aimed to investigate the potential of poly-δ-decalactone (PDL) and a block copolymer (methoxy-poly(ethylene glycol)-b-poly-δ-decalactone (mPEG-b-PDL)) in the topical delivery of ketoconazole (KTZ) and eugenol (EUG) against Candida albicans. The nanoemulsion (NE) was studied for its significant factors and was optimized using the design of experiments (DOE) methodologies. A simple robust nanoprecipitation method was employed to successfully produce a nanoemulsion (KTZ-EUG-NE). The spherical globules exhibited rough surfaces, explaining the adsorption of mPEG-b-PDL onto PDL. The sustained drug release effects were governed by the amorphous nature of PDL. KTZ-EUG-NE was further used to develop a 1% w/v Carbopol-940-based nanoemulgel (KTZ-EUG-NE gel). The optimal rheological and spreadability properties of the developed nanoemulgel explain the ease of topical applications. Ex vivo permeation and retention studies confirmed the accumulation of KTZ-EUG-NE at different layers of the skin when applied topically. The cytotoxicity of the developed NE in human keratinocyte (HaCaT) cells demonstrated the utility of this newly explored nanocarrier in reducing the cell toxicity of KTZ. The higher antifungal activities of KTZ-EUG-NE at 19.23-fold lower concentrations for planktonic growth and 4-fold lower concentrations for biofilm formation than coarse drugs explain the effectiveness of the developed NE.

Abstract
This study aimed to formulate diacerein loaded terpene-enriched invasomes (DCN-TINV) to fulfill a fruitful management of osteoarthritis. A 23 factorial design was adopted, including A: cholesterol concentration (%w/v), B: ethanol volume (mL) and C: phosphatidylcholine: drug ratio as the studied factors. Invasomes were constructed using the thin film hydration technique. Herein, percent entrapment efficiency (EE%), particle size (PS), poly-dispersity index (PDI) and zeta potential (ZP) were statistically analyzed using Design-Expert® software to select the optimum formula. The selected criteria for detecting the optimum formula were restricting PS (<350 nm), dismissing PDI, magnifying ZP (as absolute value) and EE%. The selected formula was further scrutinized through multiple in-vitro studies, including Fourier-transform infrared spectroscopy, differential scanning calorimetry, pH measurement, stability study, release profile and transmission electron microscopy. Furthermore, the ex-vivo performance was evaluated through ex-vivo skin permeation and deposition. Finally, it was subjected to an array of in-vivo tests, namely Draize test, histopathology, In-vivo skin penetration, edema size, and nociception inhibition measurements. The optimum formula with desirability (0.913) demonstrated EE% (89.21% ± 2.12%), PS (319.75 ± 10.11 nm), ZP (-55 ± 3.96 mV) and a prolonged release profile. Intriguingly, revamped skin permeation (1143 ± 32.11 µg/cm2), nociception inhibition (77%) and In-vivo skin penetration (144 µm) compared to DCN suspension (285 ± 21.25 µg/cm2, 26% and 48 µm, respectively) were displayed. The optimum DCN-TINV exhibited plausible safety and stability profiles consolidated with auspicious efficacy for better management of osteoarthritis.

Abstract
Topical drug delivery employing drug nanocarriers has shown prominent results in treating topical ailments, especially those confined to the skin and eyes. Conventional topical formulations persist with drug and disease-related challenges during treatment. Various nanotechnology-driven approaches have been adopted to mitigate the issues associated with conventional formulations. Among these, cubosomes have shown potential applications owing to their liquid crystalline structure, which aids in bioadhesion, retention, sustained release, and loading hydrophilic and hydrophobic moieties. The phase transition behavior of glyceryl monooleate, the concentration of stabilizers, and critical packing parameters are crucial parameters that affect the formation of cubosomes. Microfluidics-based approaches constitute a recent advance in technologies for generating stable cubosomes. This review covers the recent topical applications of cubosomes for treating skin (psoriasis, skin cancer, cutaneous candidiasis, acne, and alopecia) and eye (fungal keratitis, glaucoma, conjunctivitis, and uveitis) diseases. The article summarizes the manufacturing and biological challenges (skin and ocular barriers) that must be considered and encountered for successful clinical outcomes. The patented products are successful examples of technological advancements within cosmeceuticals that support various topical applications with cubosomes in the pharmaceutical field.

Abstract
Osteoarthritis is a bone and joint condition characterized pathologically by articular cartilage degenerative damage and can develop into a devastating and permanently disabling disorder. This investigation aimed to formulate the anti-inflammatory drug lornoxicam (LOR) into bile salt-enriched vesicles loaded in an in situ forming hydrogel as a potential local treatment of osteoarthritis. This was achieved by formulating LOR-loaded bilosomes that are also loaded with superparamagnetic iron oxide nanoparticles (SPIONs) for intra-muscular (IM) administration to improve joint targeting and localization by applying an external magnet to the joint. A 31.22 full factorial design was employed to develop the bilosomal dispersions and the optimized formula including SPION (LSB) was loaded into a thermosensitive hydrogel. Moreover, in vivo evaluation revealed that the IM administration of LSB combined with the application of an external magnet to the joint reversed carrageen-induced suppression in motor activity and osteoprotegerin by significantly reducing the elevations in mitogen-activated protein kinases, extracellular signal-regulated kinase, and receptor activator of nuclear factor kappa beta/osteoprotegerin expressions. In addition, the histopathological evaluation of knee joint tissues showed a remarkable improvement in the injured joint tissues. The results proved that the developed LSB could be a promising IM drug delivery system for osteoarthritis management.

Abstract
This study aimed to formulate diacerein (DCN)-loaded flexosomes for enhanced efficacy against osteoarthritis. A 23 D-optimal design was employed, investigating the impact of surfactant type (A), surfactant concentration (%w/v) (B), and oleylamine amount (mg) (C). Flexosomes were formulated using a rotary evaporator, and Design-Expert® software was utilized to statistically analyze entrapment efficiency (EE%), zeta potential (ZP), poly-dispersity index (PDI), and particle size (PS) to determine the optimum formula. The selection criteria prioritized increased ZP (as absolute value) and EE%, coupled with decreased PDI and PS. Rigorous physicochemical, in vivo, and ex vivo tests were conducted to validate the safety, stability, and activity of the optimal formula. Physicochemical assessments encompassed pH measurement, transmission electron microscopy, differential scanning calorimetry, release profiles, storage effects, and Fourier transform infrared spectroscopy. In vivo tests included permeation studies, histopathology, anti-inflammatory activity, and skin irritancy, while ex vivo tests focused on permeation parameters and skin deposition. The optimum formula demonstrated high desirability (0.931), along with favorable EE% (90.93%), ZP (- 40.4 mV), particle size (188.55 nm), and sustained behavior. Notably, improved in vivo permeation (132 µm), skin deposition (193.43 µg/cm2), and antinociceptive activity (66%) compared to DCN suspension (48 µm, 66.31 µg/cm2, and 26%, respectively) were observed. The optimal formula also exhibited excellent safety and storage characteristics. In conclusion, DCN-loaded flexosomes exhibit significant potential for effectively managing osteoarthritis.

Abstract
Targeted drug delivery is achieving great success in cancer therapy due to its potential to deliver drugs directly to the action site. Terbinafine hydrochloride (TER) is a broad-spectrum anti-fungal drug that has been found to have some potential anti-tumor effects in the treatment of colon cancer. We aimed here to design and develop pH-sensitive Eudragit (Eud)-coated mesoporous silica nanostructures (MSNs) to control drug release in response to changes in pH. The diffusion-supported loading (DiSupLo) technique was applied for loading TER into the MSNs. The formulation was optimized by a D-optimal design, which permits the concurrent assessment of the influence of drug/MSN%, coat concentration, and MSN type on the drug entrapment efficiency (EE) and its release performance. The optimal formula displayed a high EE of 96.49%, minimizing the release in pH 1.2 to 16.15% and maximizing the release in pH 7.4 to 78.09%. The cytotoxicity of the optimal formula on the colon cancer cells HT-29 was higher than it was with TER alone by 2.8-fold. Apoptosis in cancer cells exposed to the optimum formula was boosted as compared to what it was with the plain TER by 1.2-fold and it was more efficient in arresting cells during the G0/G1 and S stages of the cell cycle. Accordingly, the repurposing of TER utilizing Eud/MSNs is a promising technique for targeted colon cancer therapy.
