Abstract
We previously established a nanoparticle-based drug delivery system (DDS) for high-dose ascorbic acid therapy by self-assembly of a lipid-modified ascorbic acid derivative, L-ascorbyl 2,6-dipalmitate (ASC-DP). The particles' morphology should be modified for effective DDSs. Here, we modulated the morphology of self-assembled ASC-DP nanoparticles using two different PEGylated lipids, distearoylphosphatidylethanolamine-polyethylene glycol (DSPE-PEG) and cholesterol-polyethylene glycol (Chol-PEG), with various PEG molecular weights. At the preparation molar ratio of 10 : 1 (ASC-DP/PEGylated lipid), rod-like nanoparticles emerged in the ASC-DP/DSPE-PEG system, whereas the ASC-DP/Chol-PEG system yielded tube-like nanoparticles. The internal structures of both rod-like ASC-DP/DSPE-PEG and tube-like ASC-DP/Chol-PEG nanoparticles were similar to that of repeated ASC-DP bilayers. The particles' surfaces featured PEGylated lipids, which stabilized the structure and dispersion of the nanoparticles. For both systems, the particle size increased slightly with increasing the PEGylated lipid's PEG molecular weight. Increasing the PEG molecular weight decreased the inner tunnel size of tube-like ASC-DP/Chol-PEG nanoparticles. A mechanism has been proposed for the rod-to-tube transformation. Surface-layer free-energy changes owing to the mixing of multiple lipids and PEG chain repulsion are thought to underlie the inner tunnels' formation. The rod-to-tube morphology of self-assembled ASC-DP nanoparticles can be modulated by controlling the PEGylated lipids' structure, including the lipid species and the PEG chain length.

A Celastrol Drug Delivery System Based on PEG Derivatives: The Structural Effects of Nanocarriers. Molecules 2023; 28:molecules28031040. [PMID: 36770710 PMCID: PMC9921568 DOI: 10.3390/molecules28031040] [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: 11/29/2022] [Revised: 12/21/2022] [Accepted: 01/05/2023] [Indexed: 01/22/2023] Open
Abstract
The therapeutic efficacy of nanoscale drug delivery systems is related to particle size, zeta potential, morphology, and other physicochemical properties. The structure and composition of nanocarriers may affect their physicochemical properties. To systematically evaluate these characteristics, three analogues, namely polyethylene glycol (PEG), PEG-conjugated octadecylamine (PEG-C18), and tri(ethylene glycol) (TEG), were explored as nanocarriers to entrap celastrol (CSL) via the injection-combined dialysis method. CSL nanoparticles were successfully prepared as orange milky solutions, which revealed a similar particle size of approximately 120 nm, with narrow distribution and a negative zeta potential of -20 mV. All these CSL nanoparticles exhibited good storage stability and media stability but presented different drug-loading capacities (DLCs), release profiles, cytotoxicity, and hemolytic activity. For DLCs, PEG-C18/CSL exhibited better CSL entrapment capacity. Regarding the release profiles, TEG/CSL showed the lowest release rate, PEG-C18/CSL presented a moderate release rate, and PEG/CSL exhibited a relatively fast release rate. Based on the different release rates, PEG-C18/CSL and TEG/CSL showed higher degrees of cytotoxicity than PEG/CSL. Furthermore, TEG/CSL showed the lowest membrane toxicity, and its hemolytic rate was below 20%. These results suggest that the structural effects of nanocarriers can affect the interactions between nanocarriers and drugs, resulting in different release profiles and antitumor activity.

Abstract
Tumor-derived membrane vesicles (TDMVs) are non-invasive, chemotactic, easily obtained characteristics and contain various tumor-borne substances, such as nucleic acid and proteins. The unique properties of tumor cells and membranes make them widely used in drug loading, membrane fusion and vaccines. In particular, personalized vectors prepared using the editable properties of cells can help in the design of personalized vaccines. This review focuses on recent research on TDMV technology and its application in personalized immunotherapy. We elucidate the strengths and challenges of TDMVs to promote their application from theory to clinical practice.

Int J Pharm 2021; 602:120599.

Abstract
Previously, we reported the formation of 100-200 nm disk- and tube-like nanoparticles by hydration of L-ascorbyl 2,6-dipalmitate (ASC-DP) and distearoylphosphatidylethanolamine polyethylene glycol 2000 (DSPE-PEG) films prepared at an initial molar ratio of 2:1. This study investigated the feasibility of nanoparticle formation with higher ASC-DP loading. Although particle size distribution determined by dynamic light scattering showed a multimodal pattern including micro-sized particles at a molar ratio of 3:1, the mean particle size gradually decreased with a further increased molar ratio. Homogeneous ca. 240 nm nanoparticles with a unimodal size distribution were obtained at a molar ratio of 10:1. FE-TEM showed that the nanoparticles at a molar ratio of 10:1 were rod-shaped with a diameter of ca. 100 nm and a length of ca. 300 nm. After centrifugation, X-ray analysis of the nanoparticle precipitates showed that these rod-like nanoparticles were composed of a series of lamellar structures with 3.7 nm repeated units. The molar ratio of ASC-DP/DSPE-PEG in the nanoparticle precipitates determined by 1H NMR measurements was 68.8:1. The rod-like nanoparticles should be composed of a core-shell structure, where a small amount of DSPE-PEG covers the lamellar structure of ASC-DP. Further increase in the ASC-DP/DSPE-PEG molar ratio over 33:1 no longer provided nanoparticles. Hence, to prepare a stable ASC-DP nanoparticle suspension, it is necessary to prepare ASC-DP/DSPE-PEG films containing at least 3 mol% DSPE-PEG.

Ascorbyl-dipalmitate-stabilised nanoemulsions as a potential localised treatment of inflammatory bowel diseases. Int J Pharm 2020; 586:119533. [PMID: 32534160 DOI: 10.1016/j.ijpharm.2020.119533] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 06/05/2020] [Accepted: 06/06/2020] [Indexed: 12/19/2022]
Abstract
Current efforts on inflammatory bowel diseases (IBD) treatment are focused on strategies for localised drug delivery at the intestinal mucosa. Despite the potential of curcumin (CC) for IBD treatment, its low solubility and stability limit its application. Thus, the design of nanocarriers that focus CC delivery at the intestinal epithelium is an area of interest. This work proposes α-tocopherol nanoemulsions (NE) stabilised by ascorbyl-2,6-dipalmitate (ADP) as intestinal CC-carriers. The antioxidant capacity of α-tocopherol and ADP could have a synergistic effect on IBD-affected tissues, characterised by an oxidative environment. We obtained nanoemulsions (NE-ADP) with size below 200 nm, negative surface charge, stable in gastrointestinal media and no toxic in the Caco-2 cell model. Intracellular retention of NE-ADP in Caco-2 cells was observed by confocal microscopy. The extremely low Papp values obtained for CC and α-tocopherol indicated the lack of transport across the Caco-2 monolayer. Control nanoemulsion stabilised by lecithin (NE-L) was greatly transported across the Caco-2 cells monolayer, confirming the relevance of ADP on the cellular retention of NE-ADP. The therapeutic potential of NE-ADP was shown by the significant decrease of intracellular ROS levels. Altogether, these results indicate the potential of NE-ADP as a novel approach for the treatment of IBD.

Abstract
Vitamin C is an electron donor and is involved in a variety of biochemical reactions in stem cell and cancer stem cell, as well as collagen synthesis and the regulation of hypoxia-inducible factor synthesis, which two affect extracellular matrix remodelling and hence cancer metastasis. Specific doses of vitamin C can stop cancer cell glycolysis and block nitroso synthesis, indicating the potential of vitamin C in cancer treatment. Recent studies preliminary revealed Vitamin C enhance the cancer's immune response to anti PD-L1 therapy through multiple indirect approaches. Herein we reviewed the recent function of vitamin C for further research in sequential aspects of cancer stem cell, extracellular matrix remodeling, cancer metastasis and cancer immunotherapy.

Abstract
Present work investigates the possibility of a polyethyleneglycolylated (PEGylated) microemulsion (ME) to deliver drug to the posterior segment of eye. Triamcinolone acetonide (TA), a widely used drug in intraocular diseases, was selected as the model drug. Based on solubility and emulsification capacity, components of microemulsion were selected and optimum formulation was obtained using a pseudoternary phase diagram. The optimized ratio of Capmul MCM C8 (oil): AccononMC8-2 (surfactant): Transcutol (cosurfactant): deionized water was 5:35.5:4.5:55. This was further PEGylated using 1,2-distearoylphosphatylethanolamine-polyethyleneglycol 2000 (DSPE-PEG 2000). This PEGylated ME loaded with TA was characterized and evaluated in vitro, ex vivo, and in vivo for topical ocular use. The developed PEGylated ME loaded with TA was homogenous, stable, and nonirritable to eye and had the ability to reach the posterior segment of eye on topical instillation.

Abstract
Nanoemulsions are vesicular systems with great potential for the delivery of drugs, which significantly depends on the appropriate selection of the components that constitute them. In this sense, the use of materials with adequate toxicity profiles for the oral route provides additional advantages in terms of safety concerns avoidance. This work describes the formulation of novel two-component nanoemulsions constituted by α-tocopherol and ascorbyl-palmitate derivatives. Among them, ascorbyl-dipalmitate allowed the formation of nanoemulsions with size values around 170 nm and negative charge; additionally, they showed strong antioxidant capacity. These nanoemulsions are proposed to the oral route, so their behaviour in intestinal conditions was evaluated by incubating the nanoemulsion in simulated intestinal fluid. This process led to the formation of an intestinal-protein corona (I-PC) at the colloidal surface that determined the interaction with the mucus barrier. The I-PC displaced the immobile-hindered particles towards a subdiffusive-diffusive population. These studies report for the first time the effect of the I-PC on the mucodiffusion behaviour of vesicular systems, a finding that may help to comprehend the performance of nanocarriers under intestinal conditions.
