Eur J Pharm Biopharm 2024; 201:114347. [PMID: 38825168 DOI: 10.1016/j.ejpb.2024.114347] [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: 02/29/2024] [Revised: 05/11/2024] [Accepted: 05/30/2024] [Indexed: 06/04/2024]
Abstract
PEGylated superoxide dismutase (PEG-SOD) is commonly used as a cytoprotective agent in radiotherapy. However, its effectiveness in preventing radiation dermatitis is limited owing to its poor skin permeability. To address this issue, a PEG-SOD-loaded dissolving microneedle (PSMN) patch was developed to effectively prevent radiation dermatitis. Initially, PSMN patches were fabricated using a template mold method with polyvinylpyrrolidone K90 as the matrix material. PSMNs exhibited a conical shape with adequate mechanical strength to penetrate the stratum corneum. More than 90 % of PEG-SOD was released from the PSMN patches within 30 min. Notably, the PSMN patches showed a significantly higher drug skin permeation than the PEG-SOD solutions, with a 500-fold increase. In silico simulations and experiments on skin pharmacokinetics confirmed that PSMN patches enhanced drug permeation and skin absorption, in contrast to PEG-SOD solutions. More importantly, PSMN patches efficiently mitigated ionizing radiation-induced skin damage, accelerated the healing process of radiation-affected skin tissues, and exhibited highly effective radioprotective activity for DNA in the skin tissue. Therefore, PSMN patches are promising topical remedy for the prevention of radiation dermatitis.

Abstract
Myocardial ischemic/reperfusion (IR) injury is a global cardiovascular disease with high mortality and morbidity. Therapeutic interventions for myocardial ischemia involve restoring the occluded coronary artery. However, reactive oxygen species (ROS) inevitably impair the cardiomyocytes during the ischemic and reperfusion phases. Antioxidant therapy holds great promise against myocardial IR injury. The current therapeutic methodologies for ROS scavenging depend predominantly on administering antioxidants. Nevertheless, the intrinsic drawbacks of antioxidants limit their further clinical transformation. The use of nanoplatforms with versatile characteristics greatly benefits drug delivery in myocardial ischemic therapy. Nanoplatform-mediated drug delivery significantly improves drug bioavailability, increases therapeutic index, and reduces systemic toxicity. Nanoplatforms can be specifically and reasonably designed to enhance molecule accumulation at the myocardial site. The present review initially summarizes the mechanism of ROS generation during the process of myocardial ischemia. The understanding of this phenomenon will facilitate the advancement of innovative therapeutic strategies against myocardial IR injury. The latest developments in nanomedicine for treating myocardial ischemic injury are then discussed. Finally, the current challenges and perspectives in antioxidant therapy for myocardial IR injury are addressed.

Abstract
Owing to their tunable blood circulation time and suitable plasma stability, polymer-based nanomaterials hold a great potential for designing and utilising multifunctional nanocarriers for efficient imaging and effective treatment of cancer. When tagged with appropriate radionuclides, they may allow for specific detection (diagnosis) as well as the destruction of tumours (therapy) or even customization of materials, aiming to both diagnosis and therapy (theranostic approach). This review provides an overview of recent developments of radiolabelled polymeric nanomaterials (natural and synthetic polymers) for molecular imaging of cancer, specifically, applying nuclear techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT). Different approaches to radiolabel polymers are evaluated from the methodical radiochemical point of view. This includes new bifunctional chelating agents (BFCAs) for radiometals as well as novel labelling methods. Special emphasis is given to eligible strategies employed to evade the mononuclear phagocytic system (MPS) in view of efficient targeting. The discussion encompasses promising strategies currently employed as well as emerging possibilities in radionuclide-based cancer therapy. Key issues involved in the clinical translation of radiolabelled polymers and future scopes of this intriguing research field are also discussed.

Abstract
Radioprotectors are agents required to protect biological system exposed to radiation, either naturally or through radiation leakage, and they protect normal cells from radiation injury in cancer patients undergoing radiotherapy. It is imperative to study radioprotectors and their mechanism of action comprehensively, looking at their potential therapeutic applications. This review intimately chronicles the rich intellectual, pharmacological story of natural and synthetic radioprotectors. A continuous effort is going on by researchers to develop clinically promising radioprotective agents. In this article, for the first time we have discussed the impact of radioprotectors on different signaling pathways in cells, which will create a basis for scientific community working in this area to develop novel molecules with better therapeutic efficacy. The bright future of exceptionally noncytotoxic derivatives of bisbenzimidazoles is also described as radiomodulators. Amifostine, an effective radioprotectant, has been approved by the FDA for limited clinical use. However, due to its adverse side effects, it is not routinely used clinically. Recently, CBLB502 and several analog of a peptide are under clinical trial and showed high success against radiotherapy in cancer. This article reviews the different types of radioprotective agents with emphasis on the strategies for the development of novel radioprotectors for drug development. In addition, direction for future strategies relevant to the development of radioprotectors is also addressed.

Abstract
CONTEXT Andrographis paniculata (Burm.f.) Nees (Acanthaceae) is widely used in tribal medicine in India and some other countries for multiple clinical applications. It contains andrographolide (AG) (diterpenoid lactone), a major phytomarker which probably accounts for its medicinal properties. OBJECTIVE This study investigates the site-specific distribution of AG in different tissues of rats and its pharmacokinetic parameter evaluation by using a validated liquid chromatography tandem mass spectrometry (LC-MS/MS) method. MATERIALS AND METHODS A simple and sensitive LC-MS/MS method has been developed and validated to quantify the presence of AG in plasma and various tissues of rat following oral administration of A. paniculata extract and AG in a dose of 133.33 and 100 mg/kg/day, respectively, for four weeks. RESULTS The present study showed that the highest concentration of AG was in kidney (156.12 ng/g) followed by liver, spleen and brain while almost same concentration was found in heart and lung. The apparent C(max), T(max), elimination half-life and total exposure (AUC(0-α)) were 115.81 ng/ml, 0.75, 2.45 and 278.44 ngh/ml, respectively. CONCLUSION This was an attempt to determine the presence of AG (a known biomarker) in tissues such as kidney, heart, lungs, brain and plasma of rats using a validated LC-MS/MS method. Furthermore, the observed reduced concentration in plasma and various tissues from 1 to 8 h might be attributed to relatively rapid elimination or distribution of AG from the central compartment.

Abstract
Human serum albumin (HSA) is used as an important plasma volume expander in clinical practice. However, the infused HSA may extravasate into the interstitial space and induce peripheral edema in treating the critical illness related to marked increase in capillary permeability. Such poor intravascular retention also demands a frequent administration of HSA. We hypothesize that increasing the molecular weight of HSA by PEGylation may be a potential approach to decrease capillary permeability of HSA. In the present study, HSA was PEGylated in a site-specific manner and the PEGylated HSA carrying one chain of polyethylene glycol (PEG) (20 kDa) per HSA molecule was obtained. The purity, PEGylated site and secondary structure of the modified protein were characterized by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), thiol group blockage method and circular dichroism (CD) measurement, respectively. In addition, the pharmacokinetics in normal mice was investigated, vascular permeability of the PEGylated HSA was evaluated in lipopolysaccharide (LPS)-induced lung injury mouse model and the pharmacodynamics was investigated in LPS-induced sepsis model with systemic capillary leakage. The results showed that the biological half-life of the modified HSA was approximately 2.3 times of that of the native HSA, PEG-HSA had a lower vascular permeability and better recovery in blood pressure and haemodilution was observed in rats treated with PEG-HSA. From the results it can be inferred that the chemically well-defined and molecularly homogeneous PEGylated HSA is superior to HSA in treating capillary permeability increase related illness because of its longer biological half-life and lower vascular permeability.

Abstract
A liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been developed and validated to determine the concentration of armillarisin succinate ester in mouse plasma and tissues, used for preclinical evaluation. Bavachin was employed as the internal standard. Separation was performed on a 3.5 µm Zorbax SB-C(18) column (30 × 2.1 mm), with a mobile phase consisting of methanol and aqueous 20 mm ammonium acetate. Both analyte and internal standard were determined using electrospray ionization and the MS data acquisition was via selected ion monitoring in negative scanning mode. Quantification was performed using the transitions m/z 333 → 233 and 323 → 221 for armillarisin succinate ester and internal standard, respectively. The method was validated with respect to linearity, accuracy, precision, recovery and stability. This assay has been successfully applied to a pharmacokinetic and tissue distribution study after intravenous injection of ASE in mouse in a dose of 10 mg/kg.
