Pharmaceutics 2023; 15:2503. [PMID: 37896262 PMCID: PMC10609791 DOI: 10.3390/pharmaceutics15102503] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Revised: 10/14/2023] [Accepted: 10/15/2023] [Indexed: 10/29/2023] Open
Abstract
GSK2606414 is a new, effective, highly selective PERK inhibitor with adenosine-triphosphate-competitive characteristics. It can inhibit endoplasmic reticulum stress and has the possibility of treating periodontitis. However, owing to its strong hydrophobicity and side effects, highly efficient pharmaceutical formulations are urgently needed to improve the bioavailability and therapeutic efficacy of GSK2606414 in the treatment of periodontitis. Herein, a novel local GSK2606414 delivery system was developed by synthesizing GSK2606414 nanoparticles (NanoGSK) and further loading NanoGSK into a collagenase-responsive hydrogel. The drug release results showed that the drug-loaded hydrogels had outstanding enzymatic responsive drug release profiles under the local microenvironment of periodontitis. Furthermore, in vitro studies showed that the drug-loaded hydrogel exhibited good cellular uptake and did not affect the growth and proliferation of normal cells, while the drug-loaded hydrogel significantly improved the osteogenic differentiation of inflammatory cells. In the evaluations of periodontal tissue repair, the drug-loaded hydrogels showed a great effect on inflammation inhibition, as well as alveolar bone regeneration. Therefore, this work introduces a promising strategy for the clinical treatment of periodontitis.

[PMID: 37336301 DOI: 10.1016/j.ijpharm.2023.123149] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 05/21/2023] [Accepted: 06/14/2023] [Indexed: 06/21/2023]
Abstract
Because of their poor water-soluble properties and non-specific distribution, most hydrophobic therapeutics had limited benefit for patients with ulcerative colitis. Herein, an in-situ oil-based gel has been developed as a rectal delivery vehicle for these therapeutics. In situ gel-forming oil (BBLG) was composed of soybean phosphatidyl choline (40%, w/w), glyceryl dioleate (50%, w/w), and ethanol (10%, w/w). The hydrophobic laquinimod (LAQ) as a model drug was easily dissolved in gel-forming oil and its solubility was reaching to 7 ± 0.1 mg/mL. Importantly, upon contact with the colonic fluids, the gel-forming oil was quickly transited to a semi-solid gel, adhering to the inflamed colon mucosa and forming a protective barrier. Transmission Electron Microscopy showed that the gel network was arranged by the connected lipid spheres and LAQ was non-crystally encapsulated into the lipid spheres. Moreover, the universal adhesive test showed that the adhesive force and the adhesive energy of BBLG toward fresh colon tissues were 711±12 mN and 25 ± 2 J/m2, which was 2.14-fold and 5-fold higher than that of the marketed Poloxamer 407 gel, respectively. Meanwhile, in vivo imaging confirmed that the retention time of BBLG in the colon lumen was more than 8 h after rectal administration. In vivo animal studies showed that BBLG also greatly enhanced the therapeutic impact of LAQ on TNBS-treated rats with ulcerative colitis, as evidenced by reduced disease activity index (DAI) scores and weight loss. Moreover, the colonic inflammation was significantly alleviated and the goblet cells were obliviously restored after treatment. Importantly, the gut mucosa barrier was largely repaired without any formation of fibrosis remodeling. Conclusively, in situ liquid gel may be a potential delivery system of hydrophobic medicines for ulcerative colitis.

Abstract
KPV (Lys-Pro-Val), which is a tripeptide derived from α-MSH (α-melanocyte-stimulating hormone), has an anti-inflammatory effect on colitis. However, KPV solution is very unstable when rectally administered, compromising its therapeutic efficacy. Herein, cysteamine-grafted γ-polyglutamic acid (SH-PGA) was synthesized by conjugating cysteamine with the carboxyl groups of γ-PGA. The synthesized SH-PGA has the thiol grafting amount of 4.5 ± 0.3 mmol/g. Without the use of the cross-linker, the SH-PGA hydrogel with 4% of the polymer was formed by self-cross-linking of thiol groups. Moreover, the formation of the SH-PGA hydrogel was not affected by KPV. The KPV/SH-PGA hydrogel presented higher elastic modulus (G') than the corresponding viscous modulus (G″) at 0.01-10 Hz, exhibiting good mechanical stability. The KPV/SH-PGA hydrogel presented a shear-thinning behavior, which was helpful for rectal administration. Only 30% of KPV was released from the KPV/SH-PGA hydrogel within 20 min, followed by a sustained-release behavior. Importantly, the stability of KPV in the SH-PGA hydrogel was obviously enhanced, which was presented by detecting its anti-inflammatory activity and promoting cell migration potential after 2 h of exposure to 37 °C. The enhanced therapeutic effect of the KPV/SH-PGA hydrogel on colitis was confirmed on 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced ulcerative colitis rats. The colitis symptoms including body weight loss and the disease activity index score were obviously attenuated by rectally administering the KPV/SH-PGA hydrogel. Besides, the KPV/SH-PGA hydrogel treatment prevented the colon shortening of TNBS-infused rats and decreased the colonic myeloperoxidase level. The morphology of the colon including the epithelial barrier, crypt, and intact goblet cells was recovered after KPV/SH-PGA hydrogel treatment. Besides, the KPV/SH-PGA hydrogel decreased the expression of proinflammatory cytokines such as tumor necrosis factor α and interleukin 6. Collectively, the KPV/SH-PGA hydrogel may provide a promising strategy for the treatment of ulcerative colitis.

Xue P, Wang L, Xu J, Liu J, Pan X, Zhao Y, Xu H. Temperature-sensitive hydrogel for rectal perfusion improved the therapeutic effect of Kangfuxin liquid on DSS-induced ulcerative colitis mice: The inflammation alleviation and the colonic mucosal barriers repair. Int J Pharm 2020; 589:119846. [PMID: 32891717 DOI: 10.1016/j.ijpharm.2020.119846] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 08/19/2020] [Accepted: 08/31/2020] [Indexed: 01/05/2023]
Abstract
Kangfuxin liquid (KFX) is a Chinese medicine extracted from Periplaneta americana dried worms, which presented the bioactive functions of anti-inflammation and promoting the gastrointestinal mucosal barriers repair. But the low availability of KFX exposed to the distal colon affects its therapeutic effect on ulcerative colitis. Herein, an in situ hydrogel containing KFX was designed by using temperature-sensitive poloxamer 407 (P-407) as material for rectal administration. Three KFX-P formulations with different P407 concentrations (17%, 20% and 25%) were designed and screened by detecting the gelation time, gelation temperature and mechanical strength of hydrogel. P407 in these formulations was able to be completely dissolved in KFX at 4 ℃ and then was in situ gelled at 37 ℃ to form a semisolid hydrogel. Moreover, the gelation time, the gelation temperature and the mechanical strength of KFX-P hydrogel are highly dependent on P407 concentration. With P407 concentration increasing, both the gelation time and gelation temperature of KFX-P accordingly decreased and the gelation temperature range becomes narrowed; while the mechanical strength increased. KFX-P-20% displayed the moderate gelation temperature (28-30 ℃), the short gelation time (26 s) and the moderate mechanical strength (G' = 4.2 × 103 Pa), which was chosen for animal study. Thereafter, ulcerative colitis mice model (UC) was established by dextran sulfate sodium (DSS) and the therapeutic effect of KFX-P on UC was evaluated by inflammation symptoms relief, colon length, colonic MPO level and colonography. After rectal administration of KFX or KFX-P, the symptoms including diarrhea and hematochezia (DAI scores), weight loss and spleen swelling were significantly hindered. Meanwhile, the colonic MPO level in these groups was significantly decreased in comparison with PBS treatment. But the therapeutic effect of KFX-P was better than KFX. Besides, the morphology and mucosal barrier of colon were evaluated by HE staining, ZO-1 and claudin-5 staining. The mucosa epithelium layer, crypt, muscle layer mucosa and submucosa were also well repaired after KFX-P treatment. The strong fluorescence of ZO-1 and claudin-5 were uniformly distributed along the whole epithelial mucosa after KFX-P treatment, indicating the effective repairing of the colonic mucosal barrier. Collectively, the temperature-sensitive KFX-P for rectal delivery could effectively promote the repair of the colon mucosal barrier and inhibit the colonic inflammation in DSS-induced mice, which may be a potential strategy for UC treatment.

Abstract
This study was aimed at formulating Lopinavir loaded Vitamin E-TPGS micelles to enhance its oral bioavailability. Lopinavir is an HIV-1 protease inhibitor with low aqueous solubility leading to poor oral bioavailability and thus frequent dosing. Drug loaded micelles were fabricated using thin film hydration technique and optimized by two-factor five-level central composite design. For this purpose independent variables selected were TPGS to drug ratio and rotational speed of rotary evaporator, whereas dependent variables chosen were particle size and % entrapment efficiency. The effect of an independent variable on the dependent variable was studied by generating a quadratic polynomial model. Results of in vitro characterization showed that prepared lopinavir micelles exhibited particle size 91.71 nm, polydispersity index 0.129, zeta potential -24.8 mV, entrapment efficiency 99.36 ± 1.06% and drug loading 20.83 ± 1.23%. Results of DSC and P-XRD evaluation revealed that drugs were successfully encapsulated inside the Vitamin E-TPGS micelles. In vitro release studies displayed enhancement in drug dissolution as a result of its loading into micelles. TEM images showed that micelles were spherical. On oral administration of lopinavir micelles; the relative bioavailability was boosted by 3.17 folds compared to lopinavir suspensions. Thus, we can conclude that TPGS based micelles possess the prodigious potential to overcome the challenges of current HAART therapy.
