Parkinson’s disease (PD) is a common neurodegenerative disease in middle-aged and older adults. Abnormal proteins such as α-synuclein are essential factors in PD’s pathogenesis. Autophagy is the main participant in the clearance of abnormal proteins. The overactive or low function of autophagy leads to autophagy stress. Not only is it difficult to clear abnormal proteins but also it can cause damage to neurons. In this article, the effects of natural products ingredients, such as salidroside, paeoniflorin, curcumin, resveratrol, corynoxine, and baicalein, on regulating autophagy and protecting neurons were discussed in detail to provide a reference for the research and development of drugs for the treatment of PD.

In the past few years, the application of ionic liquids (ILs) had attracted more attention of the researchers. Many studies focused on extracting active components from traditional herbals using ILs as alternative solvents so as to address the issue caused by the traditional methods for extraction of natural products (NPs) with organic chemical reagents. Through the summary of reported research work, an overview was presented for the application of ILs or IL-based materials in the extraction of NPs, including flavonoids, alkaloids, terpenoids, phenylpropanoids and so on. Here, we mainly describe the application of ILs to rich the extraction of critical bioactive constituents that were reported possessing multiple therapeutic effects or pharmacological activities, from medicinal plants. This review could shed some light on the wide use of ILs in the field of natural products chemistry to further reduce the environmental damage caused by large quantity of organic chemical reagents.

The 1-tetralone scaffold and its derivatives are not only important as pharmacological agents but these also serve as precursors for natural products and compounds of medicinal importance. The easiest way to introduce a substituent on an aromatic as well as aliphatic system is nitration. Once introduced, the –NO2 group can be easily replaced by a wide range of functional groups. The review aims to highlight strategies for nitration of substituted and unsubstituted 1-tetralone which led to introduction of NO2 functionality at various positions.

Natural products have antitumor, anti-inflammatory, antioxidant, and other pharmacological activities and are an important source of drugs for prevention and treatment of various diseases. However, the inherent defects of natural products in physiological media such as poor solubility and stability and short biological half-life limit their clinical application. In recent years, more and more attention has been paid to the science of drug delivery by nanoscale materials. A large number of in vitro and in vivo studies have further confirmed the efficacy and safety of nanomedicine based on natural products in preclinical models of various diseases. In this review, we summarized the achievements of nanomaterials in improving the efficacy of natural products, introduced the research progress in several key fields of natural product-based nanomedicine in medical application, and discussed the challenges and prospects of clinical transformation of nanomedicine.

Hippocampus is an important traditional marine Chinese medicinal resource that has been used to warm and tonify kidney yang in the clinic for a long time in China. Modern pharmacological studies show that its active ingredients display a wide range of pharmacological activities associated with the kidney, such as anti-inflammation, antioxidation, antitumor, and neuroprotective effects. Herein, we systematically summarize and analyze the research progress on the resource distribution, active ingredients, pharmacological activities, and clinical application of Hippocampus. First, the species and worldwide distribution of Hippocampus were assessed to clarify the existing resources, and the results showed that 44 species of Hippocampus have been found in 159 countries and regions worldwide. Then, based on the analysis of 16 kinds of active ingredients and extraction methods, the relationship between the ingredient extraction and pharmacological activities of Hippocampus was revealed. This review may provide a foundation for further research on the potential active ingredients and mechanisms of Hippocampus. In addition, the research status of traditional prescriptions containing Hippocampus was evaluated. The results implied that research on Hippocampus is still in its infancy, and the mechanism and material basis of its efficacy have not been clarified. This paper should provide directions for further studies on Hippocampus.

Abstract Scutellaria baicalensis Georgi. (SB) is a common heat-clearing medicine in traditional Chinese medicine (TCM). It has been used for thousands of years in China and its neighboring countries. Clinically, it is mostly used to treat diseases such as cold and cough. SB has different harvesting periods and processed products for different clinical symptoms. Botanical researches proved that SB included in the Chinese Pharmacopoeia (1st, 2020) was consistent with the medicinal SB described in ancient books. Modern phytochemical analysis had found that SB contains hundreds of active ingredients, of which flavonoids are its major components. These chemical components are the material basis for SB to exert pharmacological effects. Pharmacological studies had shown that SB has a wide range of pharmacological activities such as antiinflammatory, antibacterial, antiviral, anticancer, liver protection, etc. The active ingredients of SB were mostly distributed in liver and kidney, and couldn't be absorbed into brain via oral absorption. SB’s toxicity was mostly manifested in liver fibrosis and allergic reactions, mainly caused by baicalin. The non-medicinal application prospects of SB were broad, such as antibacterial plastics, UV-resistant silk, animal feed, etc. In response to the Coronavirus Disease In 2019 (COVID-19), based on the network pharmacology research, SB’s active ingredients may have potential therapeutic effects, such as baicalin and baicalein. Therefore, the exact therapeutic effects are still need to be determined in clinical trials. SB has been reviewed in the past 2 years, but the content of these articles were not comprehensive and accurate. In view of the above, we made a comprehensive overview of the research progress of SB, and expect to provide ideas for the follow-up study of SB.
