Abstract
INTRODUCTION Biomacromolecules have proven to be an attractive choice for treating diseases due to their properties of strong specificity, high efficiency, and low toxicity. Besides greatly improving the patient's complaint, oral delivery of macromolecules also complies with hormone physiological secretion, which has become one of the most innovative fields of research in recent years. AREAS COVERED Oral delivery biological barriers for biomacromolecule, transport mechanisms, and various administration strategies were discussed in this review, including absorption enhancers, targeting nanoparticles, mucoadhesion nanoparticles, mucus penetration nanoparticles, and intelligent bionic drug delivery systems. EXPERT OPINION The oral delivery of biomacromolecules has important clinical implications; however, these are still facing the challenges of low bioavailability due to certain barriers. Various promising technologies have been developed to overcome the barriers and improve the therapeutic effect of oral biomacromolecules. By considering safety and efficacy comprehensively, the development of intelligent nanoparticles based on the GIT environment has demonstrated some promise in overcoming these barriers; however, a more comprehensive understanding of the oral fate of oral biomacromolecules is still required.

[PMID: 34487859 DOI: 10.1016/j.actbio.2021.08.046] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 08/18/2021] [Accepted: 08/27/2021] [Indexed: 12/29/2022]
Abstract
Mucoadhesive and mucopenetrating nanoparticles are commonly designed to improve mucosal drug delivery efficiency. Herein, in order to better understand the contribution of mucoadhesion and mucopenetration in oral delivery of biomacromolecules, insulin-loaded poly (n-butylcyanoacrylate) nanoparticles (Ins/PBCA NPs) with different coating layers, chitosan (CS) or alginate (Alg), were designed and their different absorption enhancing mechanisms were explored. It was demonstrated that both the mucoadhesive (Ins/PBCA/CS) and the mucopenetrating (Ins/PBCA/CS/Alg) nanoparticles showed good stability and similar release profiles in the gastrointestinal fluid, the mucoadhesive nanoparticles presented an enrichment in mucus (70%, 10 min) while most of the mucopenetrating nanoparticles penetrated through the mucus (80%, 10 min). Uptake mechanism studies revealed clathrin- and caveolae-mediated endocytosis were mainly involved in the intestinal transport of mucoadhesive nanoparticles while caveolae-mediated endocytosis and macropinocytosis contributed to the absorption of mucopenetrating nanoparticles, and especially, M cells favored the absorption of mucoadhesive nanoparticles. In vivo studies revealed that the mucopenetrating nanoparticles had a fast onset of action while the mucoadhesive nanoparticles presented a sustained hypoglycemic effect in diabetic rats, and overall no significant difference in pharmacological availability was found between the mucopenetrating (8.80%) and mucoadhesive nanoparticles (8.44%). To sum up, due to the varied absorption mechanism in intestine, the mucoadhesive nanoparticles designed herein had a comparable effect in enhancing oral insulin absorption compared with the mucopenetrating nanoparticles. STATEMENT OF SIGNIFICANCE: In order to improve oral delivery efficiency of insulin, insulin-loaded nanoparticles with opposite properties namely mucoadhesion and mucopenetration have been widely developed to either prolong their residence at the absorption site or improve their penetration across mucus. However, their individual contribution in oral insulin absorption is still unclear. In this paper, insulin-loaded poly (n-butylcyanoacrylate) nanoparticles with both properties were designed via different surface coating and their absorption enhancing mechanisms were explored. It was demonstrated that the mucoadhesive and mucopenetrating nanoparticles showed varied retention and mucus-penetration ability in mucus, with different absorption mechanism in intestine, but no statistical difference in pharmacological availability was found between them. Overall, the present work provides us a guidance for the design of oral nano-delivery system.

Abstract
Mucus penetration and intestinal cells targeting are two main strategies to improve insulin oral delivery efficiency. However, few studies are available regarding the effectiveness of combining these two strategies into one nano-delivery system. For this objective, the folic acid (FA) decorated virus-mimicking nanoparticles were designed and influence of FA graft ratio on the in vitro and in vivo properties of insulin loaded nanoparticles was studied systemically. Firstly, using folic acid as active ligand, different folic acid grafted chitosan copolymers (FA-CS) were synthesized and characterized. Thereafter, using insulin-loaded poly(n-butylcyanoacrylate) nanoparticles as the core, virus-mimicking nanoparticles were fabricated by coating of positively charged FA-CS copolymer and negatively charged hyaluronic acid. Irrespective of the FA graft ratio, all the nanoparticles showed good stability, similar insulin release in the gastrointestinal fluid, excellent and similar penetration in mucus. The nanoparticles permeability in intestine was FA graft ratio and segment dependent, with FA graft ratio at/over 12.51% presenting better effect in the order of duodenum > jejunum ≈ ileum. Both mechanism studies and confocal microscopy observation demonstrated FA-mediated process was involved in the transport of FA decorated nanoparticles. In vivo studies revealed hypoglycemic effect of the nanoparticles was FA graft ratio dependent, a saturation phenomenon was observed when FA graft ratio was at/over 12.51%. In conclusion, folic acid decorated virus-mimicking nanoparticles presented improved insulin absorption, implying combining mucus penetration and active transcellular transport is an effective way to promote oral insulin absorption, while the modification ratio of active ligand needs optimization.

Abstract
Heparins show great anticoagulant effect with few side effects, and are administered by subcutaneous or intravenous route in clinics. To improve patient compliance, oral administration is an alternative route. Nonetheless, oral administration of heparins still faces enormous challenges due to the multiple obstacles. This review briefly analyzes a series of barriers ranging from poorly physicochemical properties of heparins, to harsh biological barriers including gastrointestinal degradation and pre-systemic metabolism. Moreover, several approaches have been developed to overcome these obstacles, such as improving stability of heparins in the gastrointestinal tract, enhancing the intestinal epithelia permeability and facilitating lymphatic delivery of heparins. Overall, this review aims to provide insights concerning advanced delivery strategies facilitating oral absorption of heparins.

Abstract
Nasal administration of insulin showed the attractive potential to improve the compliance of diabetic patients and alleviate mild cognitive impairment of Alzheimer's patients. However, the nasal absorption of insulin was not ideal, limiting its therapeutic effect in clinic. This study was to explore the potential of glyceryl monocaprylate-modified chitosan (CS-GMC) on the intranasal absorption of insulin via in vivo pharmacodynamic experiment in conscious rats. It was demonstrated that the absorption-enhancing effect of CS-GMC depended on the existing state of insulin in the formulation, substitution degree of GMC on chitosan and concentration of CS-GMC. Better insulin absorption was achieved when insulin existed in molecular form compared with that in polyelectrolyte complexes. CS-GMC with substitution degree 12% (CS-GMC 12%) was a preferred absorption enhancer, and its absorption enhancing effect increased linearly with the increment of its concentration in the range investigated. Compared with chitosan of the same concentration, CS-GMC12% showed remarkably enhanced and prolonged therapeutic effect up to at least 5 h under the concentration of 0.6% (w/v). CS-GMC12% showed almost no ciliotoxicity to the nasal cilia up to concentration 1.0% (w/v). In conclusion, CS-GMC was a promising absorption enhancer to improve the intranasal absorption of insulin.

Abstract
Liver-targeted nanoparticles is highly desired for better therapy of liver cancer. In this study, enhanced delivery of doxorubicin (DOX) to the liver cells through self-assembled nanoparticles formed via conjugation of glycyrrhetinic acid (GA) to the hydroxyl group of hyaluronic acid (HA) was investigated. The DOX loaded hyaluronic acid-glycyrrhetinic acid succinate (HSG) conjugates based nanoparticles (HSG/DOX nanoparticles) were sub-spherical in shape with particle size in the range of 180-280 nm, the drug loading was drug-to-carrier ratio and GA graft ratio dependent. In vitro release study suggested that the release of DOX from HSG nanoparticles was sustained and the release rate was pH and GA graft ratio dependent. MTT assay indicated the HSG/DOX nanoparticles presented a GA-dependent cytotoxicity to HepG2 cells. Pharmacokinetics study demonstrated the HSG/DOX nanoparticles could prolong blood circulation time of DOX and had a higher AUC value than that of DOX solution. Furthermore, tissue distribution study revealed the HSG/DOX nanoparticles significantly increased the accumulation of DOX in the liver and meanwhile decreased the cardiotoxicity and nephrotoxicity of DOX. Moreover, the liver targeting enhancing capacity was HSG conjugate structure dependent. The accumulation of HSG-20/DOX, HSG-12/DOX, and HSG-6/DOX nanoparticles in the liver was 4.0-, 3.1-, and 2.6-fold higher than that of DOX solution. In vivo imaging analysis further demonstrated HSG nanoparticles not only had better liver targeting effect, but also presented superior tumor targeting efficiency, and the tumor targeting capacity was also GA-dependent. These results indicated that HSG conjugates prepared via modifying the hydroxyl groups of HA have promising potential as a liver-targeting nanocarrier for the delivery of hydrophobic anti-tumor drugs.

Abstract
Aim: The present study reports insulin (INS)- and quercetin (QT)-lyotropic liquid crystalline nanoparticles (LCNPs) with improved bioavailability, antidiabetic and antioxidant efficacy following oral administration. Materials & methods: The developed INS-QT-LCNPs were evaluated for simulated gastric fluid stability. In vitro Caco-2 uptake studies were also performed. Furthermore, in vivo pharmacokinetics and pharmacodynamics of INS-QT-LCNPs were evaluated. Results & conclusion: INS entrapped within LCNPs demonstrated excellent stability in simulated gastric fluid. Higher uptake of fluorescein isothiocyanate-INS-LCNPs were observed in Caco-2 cells. INS-LCNPs demonstrated approximately 20% relative bioavailability compared with subcutaneously administered INS. Significant decrease in oxidative stress was confirmed by reduction in malondialdehyde level. Overall, combination strategy not only overcomes poor oral bioavailability of INS and QT, but also prevents the generation of reactive oxygen species, responsible for diabetes-mediated complications.

Abstract
The objective of this study was to design intestinal mucus-penetrating core-shell nanocomplex by functionally mimicking the surface of virus, which can be used as the carrier for peroral delivery of macromolecules, and further understand the influence of nanocomplex surface properties on the mucosal permeation capacity. Taking insulin as a model drug, the core was formed by the self-assembly among positively charged chitosan, insulin and negatively charged sodium tripolyphosphate, different types of alginates were used as the shell forming material. The nanocomplex was characterized by dynamic light scattering (DLS), atomic force microscopy (AFM) and FTIR. Nanocomplex movement in mucus was recorded using multiple particle tracking (MPT) method. Permeation and uptake of different nanocomplex were studied in rat intestine. It was demonstrated that alginate coating layer was successfully formed on the core and the core-shell nanocomplex showed a good physical stability and improved enzymatic degradation protection. The mucus penetration and MPT study showed that the mucus penetration capacity of the nanocomplex was surface charge and coating polymer structure dependent, nanocomplex with negative alginate coating had 1.6-2.5 times higher mucus penetration ability than that of positively charged chitosan-insulin nanocomplex. Moreover, the mucus penetration ability of the core-shell nanocomplex was alginate structure dependent, whereas alginate with lower G content and lower molecular weight showed the best permeation enhancing ability. The improvement of intestine permeation and intestinal villi uptake of the core-shell nanocomplex were further confirmed in rat intestine and multiple uptake mechanisms were involved in the transport process. In conclusion, core-shell nanocomplex composed of oppositely charged materials could provide a strategy to overcome the mucus barrier and enhance the mucosal permeability.

Abstract
Herein, we develop a novel integrated strategy for the preparation of theranostic chitosan microcapsules by encapsulating ion liquids (ILs) and Fe3O4 nanoparticles. The as-prepared chitosan/Fe3O4@IL microcapsules exhibit not only significant heating efficacy in vitro under microwave (MW) irradiation but also obvious enhancement of T2-weighted magnetic resonance (MR) imaging, besides the excellent biocompatibility in physiological environments. The chitosan/Fe3O4@IL microcapsules show ideal temperature rise and therapeutic efficiency when applied to microwave thermal therapy in vivo. Complete tumor elimination is realizing after MW irradiation at an ultralow power density (1.8 W/cm(2)), while neither the MW group nor the chitosan microcapsule group has significant influence on the tumor development. The applicability of the chitosan/Fe3O4@IL microcapsules as an efficient contrast agent for MR imaging is proved in vivo. Moreover, the result of in vivo systematic toxicity shows that chitosan/Fe3O4@IL microcapsules have no acute fatal toxicity. Our study presents an interesting type of multifunctional platform developed by chitosan microcapsule promising for imaging-guided MW thermotherapy.

Suksiriworapong J, Phoca K, Ngamsom S, Sripha K, Moongkarndi P, Junyaprasert VB. Comparison of poly(ε-caprolactone) chain lengths of poly(ε-caprolactone)-co-d-α-tocopheryl-poly(ethylene glycol) 1000 succinate nanoparticles for enhancement of quercetin delivery to SKBR3 breast cancer cells. Eur J Pharm Biopharm 2016; 101:15-24. [PMID: 26802701 DOI: 10.1016/j.ejpb.2016.01.008] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2015] [Revised: 01/11/2016] [Accepted: 01/14/2016] [Indexed: 01/10/2023]
Abstract
This study aimed to investigate the effect of the different hydrophobic chain lengths of poly(ε-caprolactone)-co-d-α-tocopheryl polyethylene glycol 1000 succinate (P(CL)-TPGS) copolymers on the nanoparticle properties and delivery efficiency of quercetin to SKBR3 breast cancer cells. The 5:1, 10:1 and 20:1 P(CL)-TPGS copolymers were fabricated and found to be composed of 25.0%, 45.2% and 66.8% of hydrophobic P(CL) chains with respect to the polymer chain, respectively. The DSC measurement indicated the microphase separation of P(CL) and TPGS segments. The crystallization of P(CL) segment occurred when the P(CL) chain was higher than 25% due to the restricted mobility of P(CL) by TPGS. The longer P(CL) chain had the higher crystallinity while decreasing the crystallinity of TPGS segment. The increasing P(CL) chain length increased the particle size of P(CL)-TPGS nanoparticles from 20 to 205 nm and enhanced the loading capacity of quercetin due to the more hydrophobicity of the nanoparticle core. The release of quercetin was retarded by an increase in P(CL) chain length associated with the increasing hydrophobicity and crystallinity of P(CL)-TPGS copolymers. The P(CL)-TPGS nanoparticles potentiated the toxicity of quercetin to SKBR3 cells by at least 2.9 times compared to the quercetin solution. The cellular uptake of P(CL)-TPGS nanoparticles by SKBR3 cells occurred through cholesterol-dependent endocytosis. The 10:1 P(CL)-TPGS nanoparticles showed the highest toxicity and uptake efficiency and could be potentially used for the delivery of quercetin to breast cancer cells.

JOURNAL OF MATERIALS SCIENCE. MATERIALS IN MEDICINE 2015; 26:171. [PMID: 25804304 DOI: 10.1007/s10856-015-5499-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/16/2014] [Accepted: 02/15/2015] [Indexed: 06/04/2023]
Abstract
This study focuses on the synthesis of Pluronic-b-poly(ε-caprolactone) bearing benzyl-oxycarbonylmethyl and carboxylic groups and the comparative study to investigate the influence of the different pendant groups on the cellular behavior. The functionalized Pluronic-b-poly(ε-caprolactone) bearing two kinds of pendant groups are synthesized via ring-opening polymerization of ε-caprolactone and 6-(benzyl-oxycarbonyl methyl)-ε-caprolactone and followed by deprotection respectively. The structure of the copolymers is confirmed and the polymeric micelles are formed by an emulsion/solvent evaporation technique. The critical micelle concentrations are improved compared with Pluronic F127, the morphologies of the micelles are spherical with the diameter on nano scale and good colloidal stability. The copolymers have good cytocompatibility and the comparative study reveals that cellular internalization, digesting by lysosome and intracellular distribution are affected by the pendant groups, moreover, the endocytosis pathway is determined by the pendant groups. Therefore, the definite internalization mechanism is beneficial for the design of polymeric micellar carriers to achieve intra- or extracellular modes of drug delivery and provide better access to either cell membrane or intracellular organelles.
