Magnolol (MG) is one of the primary active components of Magnoliae officinalis cortex, which has been widely used in traditional Chinese and Japanese herbal medicine and possesses a wide range of pharmacological activities. In recent years, attention has been drawn to this component due to its potential as an anti-inflammatory and antitumor drug. To summarize the new biological and pharmacological data on MG, we screened the literature from January 2011 to October 2020. In this review, we provide an actualization of already known anti-inflammatory, cardiovascular protection, antiangiogenesis, antidiabetes, hypoglycemic, antioxidation, neuroprotection, gastrointestinal protection, and antibacterial activities of MG. Besides, results from studies on antitumor activity are presented. We also summarized the molecular mechanisms, toxicity, bioavailability, and formulations of MG. Therefore, we provide a valid cognition of MG.

Sempervivum tectorum has a similar effect as aloe vera, which is known in the treatment of various skin diseases. This herb is considered one of the safest remedies for a wide range of skin diseases. Due to its anti-inflammatory and antiseptic properties, it also serves as an excellent first aid for burns, stings and bites, because it provides quick relief and calming. Freshly squeezed juice from the leaves of the houseplant is used in the treatment of nervous disorders, epilepsy and restless dreams. The leaves are edible and can be used as an addition to salads or stews. They are not particularly tasty, but as they are rich in water, they can be put in a juicer together with other fruits or vegetables and become a refreshing drink. It is used in folk herbal medicine and as a medicine. The aim of this study was to determine the moisture content, total extracted substances, extract density, vitamin C, organic acids and proteins in house extracts.

MicroRNAs, small non-coding RNA molecules, have gained a reputation of the most substantial regulators in gene network with the ability to down-regulate their targets. Accumulating evidence shifted insight toward microRNAs regulation as the key element of cancer initiation, development, and aggression. Recent studies have attached the importance of traditional Chinese medicine (TCM) to the treatment of various cancers, and the functional natural compounds have been considered as novel anticancer agents to directly inhibit tumor progression. In more recent decades, a wide range of biologically active components of TCM has gained increasing attention to their applications in the modulation of microRNAs. This review is on the purpose of demonstrating the significance of TCM bioactive ingredients in microRNAs regulation for cancer treatment according to the reports mainly in the recent six years, providing the evidence of efficient Chinese herbal medicine-based therapy and effective pro-diagnosis focusing on microRNAs expression of cancer patients.

Turmeric (Curcuma longa L.) is a popular natural drug, traditionally used for the treatment of a wide range of diseases. Its root, as its most popular part used for medicinal purposes, contains different types of phytochemicals and minerals. This review summarizes what is currently known on biochemistry, safety, pharmacological activities (mechanistically), and clinical applications of turmeric. In short, curcumin is considered as the fundamental constituent in ground turmeric rhizome. Turmeric possesses several biological activities including anti-inflammatory, antioxidant, anticancer, antimutagenic, antimicrobial, antiobesity, hypolipidemic, cardioprotective, and neuroprotective effects. These reported pharmacologic activities make turmeric an important option for further clinical research. Also, there is a discussion on its safety and toxicity.

Abstract N-stearoylethanolamide (NSE)– a cannabinoid-like compound with wide range of biological activity. Anti-inflammatory properties of NSE have been indicated on different animal models of pathological conditions. However, the molecular mechanisms of anti-inflammatory action of NSE remain unclear. In the current study, the involvement of PPARγ in the NF-kB -dependent anti-inflammatory action of NSE was evaluated using different methodological approach. First method - molecular modeling, evaluated the possibility of NSE to bind with PPAR. Then, in ex vivo experiment, using selective synthetic agonist of PPARα/γ LY-171883 and selective antagonist of PPARγ - GW9662, the role of PPARα /PPARγ in the NSE’s effect on nuclear NF-kB translocation was examined in LPS-activated rat peritoneal macrophages. Finally, the NSE action on the mRNA level of several PPARγ- dependent genes was studied in liver of insulin-resistant rats. The molecular docking results showed that NSE could bind to PPARγ and compete for the binding with antagonist GW9662 and agonist LY171883 in the active site of PPARγ. It also has been found that NSE prevented the LPS-induced NF-kB translocation into the nuclei of rat peritoneal macrophages during pre-treatment with NSE before LPS application. When NSE was added before GW9662 and LPS treatment, the level of NF-kB translocation and IL-1β content reduced to control cells’ levels. These data confirmed a competitive binding of NSE with GW9662 for the ligand-binding domen of PPARγ. In addition, NSE administration to insulin resistant rats changed the mRNA expression of several PPARγ target gens, including FATP1 and IL1-ra.

As one of the natural resin materials produced by bees, propolis has been used as a traditional medicine for various diseases because of its biological and pharmacological activities. The purpose of this study was to analyze the potential of propolis as a healing agent for pulp injuries. A total of 35 journals from PubMed, Ebsco, ResearchGate, Wiley Online Library, and other international journal databases were analyzed. Propolis is very rich in active components such as flavonoids that have biological functions such as anti-inflammatory, antibacterial, antifungal and antioxidant which can act as a potential healing agent

Biflavonoids, composed of two monoflavonoid residues, occur naturally in angiosperms, bryophytes, ferns, and gymnosperms. More than 592 biflavonoids have been structurally elucidated, and they can be classified into two groups of C-C and C-linear fragments-C, based on whether the linker between the two residues contains an atom. As the linker can be established on two arbitrary rings from different residues, the C-C type contains various subtypes, as does the C-linear fragment-C type. Biflavonoids have a wide range of pharmacological activities, including anti-inflammatory, antioxidant, antibacterial, antiviral, antidiabetic, antitumor, and cytotoxic properties, and they can be applied in Alzheimer’s disease and Parkinson’s disease. This review mainly summarizes the distribution and chemistry of biflavonoids; additionally, their bioactivities, pharmacokinetics, and synthesis are discussed.
