Lipid-Based Self-Microemulsion of Niclosamide Achieved Enhanced Oral Delivery and Anti-Tumor Efficacy in Orthotopic Patient-Derived Xenograft of Hepatocellular Carcinoma in Mice. Int J Nanomedicine 2024; 19:2639-2653. [PMID: 38500681 PMCID: PMC10946447 DOI: 10.2147/ijn.s442143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 02/20/2024] [Indexed: 03/20/2024] Open
Abstract
Introduction We previously identified niclosamide as a promising repurposed drug candidate for hepatocellular carcinoma (HCC) treatment. However, it is poorly water soluble, limiting its tissue bioavailability and clinical application. To overcome these challenges, we developed an orally bioavailable self-microemulsifying drug delivery system encapsulating niclosamide (Nic-SMEDDS). Methods Nic-SMEDDS was synthesized and characterized for its physicochemical properties, in vivo pharmacokinetics and absorption mechanisms, and in vivo therapeutic efficacy in an orthotopic patient-derived xenograft (PDX)-HCC mouse model. Niclosamide ethanolamine salt (NEN), with superior water solubility, was used as a positive control. Results Nic-SMEDDS (5.6% drug load) displayed favorable physicochemical properties and drug release profiles in vitro. In vivo, Nic-SMEDDS displayed prolonged retention time and plasma release profile compared to niclosamide or NEN. Oral administration of Nic-SMEDDS to non-tumor bearing mice improved niclosamide bioavailability and Cmax by 4.1- and 1.8-fold, respectively, compared to oral niclosamide. Cycloheximide pre-treatment blocked niclosamide absorption from orally administered Nic-SMEDDS, suggesting that its absorption was facilitated through the chylomicron pathway. Nic-SMEDDS (100 mg/kg, bid) showed greater anti-tumor efficacy compared to NEN (200 mg/kg, qd); this correlated with higher levels (p < 0.01) of niclosamide, increased caspase-3, and decreased Ki-67 in the harvested PDX tissues when Nic-SMEDDS was given. Biochemical analysis at the treatment end-point indicated that Nic-SMEDDS elevated lipid levels in treated mice. Conclusion We successfully developed an orally bioavailable formulation of niclosamide, which significantly enhanced oral bioavailability and anti-tumor efficacy in an HCC PDX mouse model. Our data support its clinical translation for the treatment of solid tumors.

Abstract
PURPOSE Numerous oral treatment options have been reported for neurological disorders, especially Alzheimer's disease (AD). Galantamine (GAL) is one of such drugs duly approved for management of AD. However, it exhibits poor brain penetration, low intestinal permeation and requires frequent dosing in AD treatment. The present studies, accordingly, were undertaken to develop DSPE-PEG 2000-based micelles loaded with GAL for efficient brain uptake, improved and extended pharmacokinetics, along with reduced dosing regimen. METHODS Mixed nanomicelles (MNMs) were systematically formulated using QbD approach, and characterized for morphology, entrapment efficiency andin vitrodrug release. RESULTS Studies on CaCo-2 and neuronal U-87 cell lines exhibited substantial enhancement in the cellular permeability and uptake of the developed MNMs. Pharmacokinetic studies performed on rats showed significantly improved values of plasma AUC (i.e., 2.28-fold, p < 0.001), ostensibly due to bypassing of hepatic first-pass metabolism and improved intestinal permeability, together with significant rise in MRT (2.08-fold, p < 0.001) and tmax (4.80-fold; p < 0.001) values, indicating immense potential for prolonged drug residence in body.Besides, substantial elevation in brain drug levels, distinctly improved levels of biochemical parameters in brain homogenates and cognitive improvement in β-amyloid-treated rats, testify the superiority in MNMs in therapeutic management of AD. CONCLUSIONS The preclinical findings of the developed nanocarrier systems successfully demonstrate the notable potential of enhanced drug efficacy, extended duration of action and improved patient compliance.

Abstract
BACKGROUND Clinically, significant herb-drug interactions have been previously documented and can be pharmacodynamic and/or pharmacokinetic in nature. Pharmacokinetic interactions have been attributed to induction or inhibition of either metabolic enzymes or efflux transporters. OBJECTIVE The effect of gel and whole leaf materials from 3 different aloe species namely Aloe ferox, Aloe marlothii, and Aloe vera as well as polysaccharides precipitated from the A. vera materials on the bi-directional transport of cimetidine across rat intestinal tissue was investigated. MATERIALS AND METHODS Cimetidine transport studies were performed across excised rat intestinal tissue mounted in Sweetana-Grass diffusion chambers in both the apical-to-basolateral and basolateral-to-apical directions. RESULTS While A. vera gel and whole leaf materials did not inhibit the efflux of cimetidine, the polysaccharides precipitated from them did show a reduction of cimetidine efflux. On the other hand, both A. ferox and A. marlothii gel and whole leaf materials exhibited an inhibition effect on cimetidine efflux. CONCLUSIONS This study identified a modulation effect of efflux transporters by certain aloe materials. This may cause herb-drug pharmacokinetic interactions when drugs that are substrates for these efflux transporters are taken simultaneously with aloe materials. On the other hand, these aloe materials may be used for drug absorption enhancement for drugs with low bioavailability due to extensive efflux.

Abstract
Drugs with low water solubility are predisposed to low and variable oral bioavailability and, therefore, to variability in clinical response. Despite significant efforts to "design in" acceptable developability properties (including aqueous solubility) during lead optimization, approximately 40% of currently marketed compounds and most current drug development candidates remain poorly water-soluble. The fact that so many drug candidates of this type are advanced into development and clinical assessment is testament to an increasingly sophisticated understanding of the approaches that can be taken to promote apparent solubility in the gastrointestinal tract and to support drug exposure after oral administration. Here we provide a detailed commentary on the major challenges to the progression of a poorly water-soluble lead or development candidate and review the approaches and strategies that can be taken to facilitate compound progression. In particular, we address the fundamental principles that underpin the use of strategies, including pH adjustment and salt-form selection, polymorphs, cocrystals, cosolvents, surfactants, cyclodextrins, particle size reduction, amorphous solid dispersions, and lipid-based formulations. In each case, the theoretical basis for utility is described along with a detailed review of recent advances in the field. The article provides an integrated and contemporary discussion of current approaches to solubility and dissolution enhancement but has been deliberately structured as a series of stand-alone sections to allow also directed access to a specific technology (e.g., solid dispersions, lipid-based formulations, or salt forms) where required.

Abstract
In this study we investigated the potential of mucoadhesive nanoparticles to enhance the intestinal permeability of docetaxel (Dtx). These nanoparticles were composed of methyl-β-cyclodextrin (Me-β-CD) combined with poly(isobutylcyanoacrylate) and coated with thiolated chitosan. In order to encapsulate the highest amount of Dtx into nanoparticles, the anionic emulsion polymerization of isobutylcyanoacrylate was carried out in a solution of Me-β-CD/Dtx inclusion complex. The resulting nanoparticles were spherical with diameters ranging from 200 to 400 nm, and positively charged. Depending on the formulation, the encapsulation efficiency of Dtx was 70-80%. In vitro experiments in simulated intestinal medium containing 1% w/v of pancreatin showed that Dtx was gradually released to reach 60% after 24h and 100% after 48 h. The capacity of these nanoparticles to enhance the flux of Dtx across the intestinal membrane was then investigated using the Ussing chamber technique. The intestinal permeation of Dtx loaded into nanoparticles was found to be higher than the ethanol control solution of Dtx. Interestingly, when mucoadhesive interactions between nanoparticles and the mucosa were avoided, the intestinal permeation of Dtx significantly decreased, confirming that the mucoadhesion of the nanoparticles was a mandatory condition to enhance the intestinal permeation of Dtx.

Abstract
This study provides evidence that quinidine can be used as a probe substrate for ABCB1 in multiple experimental systems both in vitro and in vivo relevant to the blood-brain barrier (BBB). The combination of quinidine and PSC-833 (valspodar) is an effective tool to assess investigational drugs for interactions on ABCB1. Effects of quinidine and substrate-inhibitor interactions were tested in a membrane assay and in monolayer assays. The authors compared quinidine and digoxin as ABCB1 probes in the in vitro assays and found that quinidine was more potent and at least as specific as digoxin in ATPase and monolayer efflux assays employing MDCKII-MDR1 and the rat brain microcapillary endothelial cell system. Brain exposure to quinidine was tested in dual-/triple-probe microdialysis experiments in rats by assessing levels of quinidine in blood and brain. Comparing quinidine levels in dialysate samples from valspodar-treated and control animals, it is evident that systemic/local administration of the inhibitor diminishes the pumping function of ABCB1 at the BBB, resulting in an increased brain penetration of quinidine. In sum, quinidine is a good probe to study ABCB1 function at the BBB. Moreover, quinidine/PSC-833 is an ABCB1-specific substrate/inhibitor combination applicable to many assay systems both in vitro and in vivo.

Abstract
Piperine, a major plant alkaloid found in black pepper (Piper nigrum) and long pepper (Piper longum), has shown potential for inhibiting the efflux pump (EP) of Staphylococcus aureus. In this study, a modulation assay showed that piperine could decrease the MIC of ethidium bromide (EtBr) twofold at 32 μg ml(-1) and fourfold at 64 μg ml(-1) against Mycobacterium smegmatis mc(2) 155 ATCC 700084. A real-time, 96-well plate fluorometric method was employed to evaluate the EP inhibition ability of piperine in M. smegmatis. Reserpine, chlorpromazine, verapamil and carbonyl cyanide m-chlorophenylhydrazone were used as positive controls. Piperine significantly enhanced accumulation and decreased the efflux of EtBr in M. smegmatis, which suggests that it has the ability to inhibit mycobacterial EPs.

Abstract
To improve the bioavailability of orally administered drugs, formulations based on polymers are of great interest for pharmaceutical technologists. Thiolated chitosans are multifunctional polymers that exhibit improved mucoadhesive, cohesive and permeation-enhancing as well as efflux-pump-inhibitory properties. They can be synthesized by derivatization of the primary amino groups of chitosan with coupling reagents bearing thiol functions. Various data gained in-vitro as well as in-vivo studies clearly demonstrate the potential of thiolated chitosans for oral drug delivery. Within the current review, the synthesis and characterization of thiolated chitosans so far developed is summarized. Features of thiolated chitosans important for oral drug delivery are discussed as well. Moreover, different formulation approaches, such as matrix tablets and micro-/nanoparticles, as well as the applicability of thiolated chitosans for the oral delivery of various substance classes including peptides and efflux pump substrates, are highlighted.
