文摘As one of the most common gynecological malignancies,peritoneal metastasis is a common feature and cause of high mortality in ovarian cancer(OC).Currently,the standard treatment for OC and its peritoneal metastasis is maximal cytoreductive surgery(CRS)combined with platinum-based chemotherapy.Compared with intravenous chemotherapy,traditional intraperitoneal(IP)chemotherapy exhibits obvious pharmacokinetic(PK)advantages and systemic safety and has shown significant survival benefits in several clinical studies of OC patients.However,there remain several challenges in traditional IP chemotherapy,such as insufficient drug retention,a lack of tumor targeting,inadequate drug penetration,gastrointestinal toxicity,and limited inhibition of tumor metastasis and chemoresistance.Nanomedicine-based IP targeting delivery systems,through specific drug carrier design with tumor cells and tumor environment(TME)targeting,make it possible to overcome these challenges and maximize local therapy efficacy while reducing side effects.In this review article,the rationale and challenges of nanomedicine-based IP chemotherapies,as well as their in vivo fate after IP administration,which are crucial for their rational design and clinical translation,are firstly discussed.Then,current strategies for nanomedicine-based targeting delivery systems and the relevant clinical trials in IP chemotherapy are summarized.Finally,the future directions of the nanomedicine-based IP targeting delivery system for OC and its peritoneal metastasis are proposed,expecting to improve the clinical development of IP chemotherapy.

文摘Background Present drug delivery systems such as oral administration and intravenous injection limit the drug efficacy of current anti-allergy drugs.Therefore,new drug delivery systems,including nanocarriers,transdermal patches,and microneedles,are being investigated for their potential to deliver anti-allergy drugs.Purpose of review The review reveals the likely improvements by applying new drug delivery systems,including nanocarriers,transdermal patches and microneedles.Recent findings These new drug delivery systems utilize local administration and do not undergo metabolism pathways in the liver.Thus,they demonstrate high drug targeting,rapid onset action,precise dosage control,and minimal side effects.Limitations on large-scale production and high costs hinder the application of advanced drug delivery systems.Fortunately,forthcoming innovation and maturation will likely overcome the barriers and enable general patients to access anti-allergy drugs delivered by these advanced drug delivery systems,resulting in optimal body functions for everyday life.Conclusion Despite their limitations,new drug delivery systems are still promising solutions for delivering anti-allergy drugs due to their enhanced drug concentration,shortened onset time,and reduced systemic side effects.

文摘Significant investment in nanocarrier drug delivery systems(Nano-DDSs)has yielded only a limited number of successfully marketed nanomedicines,highlighting a low rate of clinical translation.A primary contributing factor is the lack of foundational understanding of in vivo processes.Comprehensive knowledge of the pharmacokinetics of Nano-DDSs is essential for developing more efficacious nanomedicines and accurately evaluating their safety and associated risks.However,the complexity of Nano-DDSs has impeded thorough and systematic pharmacokinetic studies.Key components of pharmacokinetic investigations on Nano-DDSs include the analysis of the released drug,the encapsulated drug,and the nanomaterial,which present a higher level of complexity compared to traditional small-molecule drugs.Establishing an appropriate approach for monitoring the pharmacokinetics of Nano-DDSs is crucial for facilitating the clinical translation of nanomedicines.This review provides an overview of advanced bioanalytical methodologies employed in studying the pharmacokinetics of anticancer organic Nano-DDSs over the past five years.We hope that this review will enhance the understanding of the pharmacokinetics of Nano-DDSs and support the advancement of nanomedicines.
文摘The phenomenon of pyroptosis has gained increasing prominence in recent decades as a significant contributor to cellular mortality.The process of pyroptosis plays a crucial role in the regulation of various types of cancers.The induction of pyroptosis can be achieved through various mechanisms,including the activation of small molecule pyrogen inducers.The use of.small molecule pyrogen inducer alone,however,has limitations.On one hand,we benefit from the utilization of nano delivery systems(NDS).On the other hand,there is an enhanced comprehension of the underlying mechanism governing pyroptosis.A novel therapeutic strategy,resulting from a clever amalgamation of the two approaches,has demonstrated significant efficacy in experimental treatment of certain diseases.A variety of nanocarriers,including liposomes,hydrogels,polymer micelles,exosomes,metal-organic frameworks protein nanoparticles,cell membrane biomimetic nanocarriers,carbon nanotubes,dendrimers,polymer conjugates and polymer nanoparticles are utilized for the delivery of drugs that induce pyroptosis in cells.By integrating the aforementioned approaches,a diverse range of pyroptosis strategies have been developed utilizing NDS,encompassing stem cell targeting,disruption of ion homeostasis,augmentation of reactive oxygen species generation,induction of epigenetic modifications,and transportation of gaseous protein gasdermins family proteins.However,the clinical application of these strategies still encounters numerous challenges that need to be addressed,including limited comprehension of NDS,incomplete understanding of the interaction mechanisms between nanomaterials and biological systems,and insufficient knowledge regarding nanocarrier materials.In this study,we aim to advance the field of pyroptosis in cancer treatment.The induction of pyroptotic cell death is believed to hold great promise as an ideal therapeutic approach for the management,regulation,and treatment of numerous types of cancers.
文摘Complications of the liver are amongst the world’s worst diseases.Liver fibrosis is the first stage of liver problems,while cirrhosis is the last stage,which can lead to death.The creation of effective anti-fibrotic drug delivery methods appears critical due to the liver’s metabolic capacity for drugs and the presence of insurmountable physiological impediments in the way of targeting.Recent breakthroughs in anti-fibrotic agents have substantially assisted in fibrosis;nevertheless,the working mechanism of anti-fibrotic medications is not fully understood,and there is a need to design delivery systems that are well-understood and can aid in cirrhosis.Nanotechnology-based delivery systems are regarded to be effective but they have not been adequately researched for liver delivery.As a result,the capability of nanoparticles in hepatic delivery was explored.Another approach is targeted drug delivery,which can considerably improve efficacy if delivery systems are designed to target hepatic stellate cells(HSCs).We have addressed numerous delivery strategies that target HSCs,which can eventually aid in fibrosis.Recently genetics have proved to be useful,and methods for delivering genetic material to the target place have also been investigated where different techniques are depicted.To summarize,this review paper sheds light on themost recent breakthroughs in drug and gene-based nano and targeted delivery systems that have lately shown useful for the treatment of liver fibrosis and cirrhosis.
文摘Nanotechnology in cancer therapy has significantly advanced treatment precision,effectiveness,and safety,improving patient outcomes and personalized care.Engineered smart nanoparticles and cell-based therapies are designed to target tumor cells,precisely sensing the tumor microenvironment(TME)and sparing normal cells.These nanoparticles enhance drug accumulation in tumors by solubilizing insoluble compounds or preventing their degradation,and they can also overcome therapy resistance and deliver multiple drugs simultaneously.Despite these benefits,challenges remain in patient-specific responses and regulatory approvals for cell-based or nanoparticle therapies.Cell-based drug delivery systems(DDSs)that primarily utilize the immune-recognition principle between ligands and receptors have shown promise in selectively targeting and destroying cancer cells.This review aims to provide a comprehensive overview of various nanoparticle and cell-based drug delivery system types used in cancer research.It covers approved and experimental nanoparticle therapies,including liposomes,micelles,protein-based and polymeric nanoparticles,as well as cell-based DDSs like macrophages,T-lymphocytes,dendritic cells,viruses,bacterial ghosts,minicells,SimCells,and outer membrane vesicles(OMVs).The review also explains the role of TME and its impact on developing smart DDSs in combination therapies and integrating nanoparticles with cell-based systems for targeting cancer cells.By detailing DDSs at different stages of development,from laboratory research to clinical trials and approved treatments,this review provides the latest insights and a collection of valuable citations of the innovative strategies that can be improved for the precise treatment of cancer.
