Sesame seeds are rich in lignan content and have been well-known for their health benefits. Unlike the other sesame lignan compounds (i.e., sesamin and sesamol), the study of the pharmacological activity of sesamolin has not been explored widely. This review, therefore, summarizes the information related to sesamolin’s pharmacological activities, and the mechanism of action. Moreover, the influence of its physicochemical properties on pharmacological activity is also discussed. Sesamolin possessed neuroprotective activity against hypoxia-induced reactive oxygen species (ROS) and oxidative stress in neuron cells by reducing the ROS and inhibiting apoptosis. In skin cancer, sesamolin exhibited antimelanogenesis by affecting the expression of the melanogenic enzymes. The anticancer activity of sesamolin based on antiproliferation and inhibition of migration was demonstrated in human colon cancer cells. In addition, treatment with sesamolin could stimulate immune cells to enhance the cytolytic activity to kill Burkitt’s lymphoma cells. However, the toxicity and safety of sesamolin have not been reported. And there is also less information on the experimental study in vivo. The limited aqueous solubility of sesamolin becomes the main problem, which affects its pharmacological activity in the in vitro experiment and clinical efficacy. Therefore, solubility enhancement is needed for further investigation and determination of its pharmacological activity profiles. Since there are fewer reports studying this issue, it could become a future prospective research opportunity.

Valerenic Acid

Valeriana officinalis L. (Caprifoliaceae family) has been traditionally used to treat mild nervous tension and sleep problems. The basis of these activities are mainly attributed to valerenic acid through the modulation of the GABA receptor. Moreover, V. officinalis is claimed to have other biological activities such as cardiovascular benefits, anticancer, antimicrobial and spasmolytic.  The current review aims to update the biological and pharmacological studies (in vitro, in vivo and clinical trials) of V. officinalis and its major secondary metabolites in order to guide future research. Databases PubMed, Science Direct and Scopus were used for literature search including original papers written in English and published between 2014 and 2020. There have been identified 33 articles which met inclusion criteria. Most of these works were performed with V. officinalis extracts and only a few papers (in vitro and in vivo studies) evaluated the activity of isolated compounds (valerenic acid and volvalerenal acid K). In vitro studies focused on studying antioxidant and neuroprotective activity. In vivo studies and clinical trials mainly investigated activities on the nervous system (anticonvulsant activity, antidepressant, cognitive problems, anxiety and sleep disorders). Just few studies were focused on other different activities, highlight effects on symptoms of premenstrual and postmenopausal syndromes. Valeriana officinalis continues to be one of the medicinal plants most used by today's society for its therapeutic properties and whose biological and pharmacological activities continue to arouse great scientific interest as evidenced in recent publications. This review shows scientific evidence on traditional uses of V. officinalis on nervous system.

Background: Andrographis paniculata, commonly known as “Kalmegh”, is an annual herbaceous plant from family Acanthaceae. The whole plant of A. paniculata has explored for multiple pharmacological activities and is scientifically recognized by in-vivo and in-vitro studies. Various biotechnologically engineered techniques have been explored to enhance the bioavailability of this plant. Objective: In this review, we aim to present comprehensive recent advances in the ethnopharmacology, phytochemistry, specific pharmacology, safety and toxicology and bioavailability of A. paniculata and its pure compounds. Possible directions for future research are also outlined in brief, which will encourage advance investigations on this plant. Methods: Information on the recent updates of the present review is collected from different electronic scientific databases such as Science Direct, PubMed, Scopus, and Google Scholar. All the composed information is classified into different sections according to the objective of the paper. Results: More than hundred research and review papers have been studied and incorporated in the present manuscript. After vast literature search of A. paniculata, we present a noteworthy report of various phytoconstituents present in plant, which are accountable for potential therapeutic properties of the plant. Forty-five of studied articles give general information about introduction, ethnobotany and traditional uses of the plant. Twenty-two papers enclosed information about the phytoconstituents present in different parts of A. paniculata and seventy-two papers briefly outlined the pharmacological activities like antioxidant, anti-dengue, anti-ulcerogenic, antifungal, some miscellaneous activities like activity against SARS-CoV-2, antidiarrhoeal. Nineteen studies highlighted the research work conducted by various researchers to increased bioavailability of A. paniculata and two studies reported the safety and toxicology of the plant. Conclusion: This review incorporated the scientifically validated research work encompassing the ethnobotanical description of the subjected plant, phytochemical profile, various pharmacological activities, and recent approaches to enhance the bioavailability of active metabolites.

Abstract Background Colon cancer represents one of the leading causes of gastrointestinal tumors in industrialized countries, and its incidence appears to be increasing at an alarming rate. Accumulating evidence has unveiled the contributory roles of cancer stem cells (CSCs) in tumorigenicity, recurrence, and metastases. The functions of NF-kappa B (NF-κB) activation on cancer cell survival, including colon cancer cells have encouraged us to study the role of NF-κB in the maintenance of CSCs in colon cancer. Methods Tumor samples and matched normal samples were obtained from 35 colon cancer cases. CSCs were isolated from human colon cancer cell lines, where the stemness of the cells was evaluated by cell viability, colony-forming, spheroid-forming, invasion, migration, and apoptosis assays. NF-κB activation was then performed in subcutaneous tumor models of CSCs by injecting lipopolysaccharides (LPS) i.p. Results We found that NF-κB activation could reduce the expression of miR-195-5p and miR-497-5p, where these two miRNAs were determined to be downregulated in colon cancer tissues, cultured colon CSCs, and LPS-injected subcutaneous tumor models. Elevation of miR-195-5p and miR-497-5p levels by their specific mimic could ablate the effects of NF-κB on the stemness of colon cancer cells in vivo and in vitro, suggesting that NF-κB could maintain the stemness of colon cancer cells by downregulating miR-195-5p/497–5p. MCM2 was validated as the target gene of miR-195-5p and miR-497-5p in cultured colon CSCs. Overexpression of MCM2 was shown to restore the stemness of colon cancer cells in the presence of miR-195-5p and miR-497-5p, suggesting that miR-195-5p and miR-497-5p could impair the stemness of colon cancer cells by targeting MCM2 in vivo and in vitro. Conclusions Our work demonstrates that the restoration of miR-195-5p and miR-497-5p may be a therapeutic strategy for colon cancer treatment in relation to NF-κB activation.
