Multidisciplinary strategies to enhance therapeutic effects of flavonoids from Epimedii Folium: Integration of herbal medicine, enzyme engineering, and nanotechnology.

Abstract Chemotherapy drugs have been used for a long time in the treatment of cancer, but serious side effects are caused by the inability of the drug to be solely delivered to the tumor when treating cancer with chemotherapy. Natural products have attracted more and more attention due to the antitumor effect in multiple ways, abundant resources and less side effects. Therefore, the combination of natural active ingredients and chemotherapy drugs may be an effective antitumor strategy, which can inhibit the growth of tumor and multidrug resistance, reduce side effects of chemotherapy drugs. Nano-drug co-delivery system (NDCDS) can play an important role in the combination of natural active ingredients and chemotherapy drugs. This review provides a comprehensive summary of the research status and application prospect of nano-delivery strategies for the combination of natural active ingredients and chemotherapy drugs, aiming to provide a basis for the development of anti-tumor drugs.

Nano-drug co-delivery system of natural active ingredients and chemotherapy drugs for cancer treatment: a review

Abstract This study presents an outline of the 12 principles of green relevance in nanomaterial synthesis. The goal of using green renewable resources is to protect the environment from negative effects, which can be achieved via several main directions, including the choice of innocuous solvents, such as supercritical (SC) fluids or water, and/or additives (i.e. stabilizers, capping, and reducing agents) such as polysaccharides, using alternative reaction circumstances, and the development of energy-efficient synthetic methods. This review shows how different green renewable resources routes are reducing the impact of chemical processes on the environment and how their benefit can be achieved in nanotechnology applications such as green energy.

Green synthesis of nanoparticles for varied applications: Green renewable resources and energy-efficient synthetic routes

In recent years, nanodrug delivery systems have attracted increasing attention due to their advantages, such as high drug loading, low toxicity and side effects, improved bioavailability, long circulation time, good targeting and controlled drug release efficiency. Self-assembly technology has developed rapidly in recent decades and plays an important role in the research and development of nanoscience. The combination of nanometer drug delivery and self-assembly technology can realize the self-delivery process of drugs. The facile synthesis process and strong biological affinity can both effectively enhance the therapeutic efficacy and reduce the toxicity of drugs. This combination of technologies has received wide attention in the field of nanobiomedicine. In this review, we summarize the research progress and applications of different types of self-assembled nanodrug delivery systems (amphiphilic block copolymer-based self-assembled drug delivery system, carrier-free nanodrugs, peptide-based self-assembled delivery system, metal-polyphenol self-assembly and natural small-molecule self-assembled nanodrug delivery systems), which are expected to have potential therapeutic value in the field of biomedicine in the future.

Research progress on self-assembled nanodrug delivery systems.

Abstract Parkinson’s disease (PD), a neurodegenerative disease that shows a high incidence in older individuals, is becoming increasingly prevalent. Unfortunately, there is no clinical cure for PD, and novel anti-PD drugs are therefore urgently required. However, the selective permeability of the blood–brain barrier (BBB) poses a huge challenge in the development of such drugs. Fortunately, through strategies based on the physiological characteristics of the BBB and other modifications, including enhancement of BBB permeability, nanotechnology can offer a solution to this problem and facilitate drug delivery across the BBB. Although nanomaterials are often used as carriers for PD treatment, their biological activity is ignored. Several studies in recent years have shown that nanomaterials can improve PD symptoms via their own nano-bio effects. In this review, we first summarize the physiological features of the BBB and then discuss the design of appropriate brain-targeted delivery nanoplatforms for PD treatment. Subsequently, we highlight the emerging strategies for crossing the BBB and the development of novel nanomaterials with anti-PD nano-biological effects. Finally, we discuss the current challenges in nanomaterial-based PD treatment and the future trends in this field. Our review emphasizes the clinical value of nanotechnology in PD treatment based on recent patents and could guide researchers working in this area in the future.
