Abstract: Pain is an unpleasant sensation that has complex and varying causative etiology. Modern drug discovery focuses on identifying potential molecules that target multiple pathways with a safer profile compared to those with a single target. The current treatment of pain and inflammation with the available therapeutics has a number of major side effects. Pain is one of the major clinical problems that need functional therapeutics which act on multiple targets and with low toxicity. Curcumin, a naturally occurring polyphenolic compound from Curcuma longa, has been used for years in Ayurvedic, Chinese, and in many other systems of traditional medicine. Pre-clinical data published thus far demonstrated that curcumin possesses multi-target biological functions, suggesting its potential use to cure different diseases. However, there is no or very brief systematic review of its potential use in pain and inflammation with underlying mechanisms for such activities. Accordingly, the aim of the current review was to update the pre-clinical data of curcumin and its multiple targeting pathways for analgesic and anti-inflammatory effects, and to further propose a molecular mechanism(s). A literature study was conducted using different known databases, including Pubmed, SciFinder, Google Scholar, and Science Direct. Available pre-clinical data suggest the ameliorating effect of curcumin in pain and inflammation is rendered through the modulation of pain pathways, including inhibition of a number of pro-inflammatory mediators, inhibition of oxidative stress and cyclooxygenase-2 (COX-2), down-regulation of Ca2+/calmodulin-depend protein kinase II (CaMKIIα) and calcium channels like transient receptor potential (TRP), modulation of metabotropic glutamate receptor-2 (mGlu2), modulation of monoamine system, inhibition of JAK2/STAT3 signaling pathway, remodeling of extracellular matrix proteins, inhibition of apoptosis, inhibition of JNK/MAPK and ERK/CREB signaling pathway, and activation of the opioid system. Taken all together, it is evident that curcumin is one of the promising, safe, and natural polyphenolic molecules that target multiple molecular pathways in pain and can be beneficial in the treatment and management of pain and inflammation.

Abstract: Tobacco is grown in large quantities worldwide as a widely distributed commercial crop. From the harvest of the field to the process into the final product, a series of procedures generate enormous amount of waste materials that are rarely recycled. In recent years, numerous potential bioactive compounds have been isolated from tobacco, and the molecular regulatory mechanisms related to the performance of some functionalities have been identified. This review describes the source of tobacco waste and expounds a large amount of biomass during the tobacco processing, and the necessity of exploring the reuse of tobacco waste. In addition, the review summarizes the bioactive compounds from tobacco that have been discovered so far, and links them to various functions from tobacco extracts, including anti-inflammatory, antitumor, antibacterial, and antioxidant, thus proving the potential value from tobacco waste reuse. In this regard, nornicotine in tobacco is the culprit of many health issues, while the polyphenols and polysaccharides often contribute to the health benefits of tobacco extract. In addition, it is hard to ignore that realization of these functions of tobacco extracts require the involvement of intestinal flora metabolism, which should be considered in the development of new product dosage forms.

Abstract: Food components have long been recognized to play a fundamental role in the growth and development of the human body, conferring protective functionalities against foreign matter that can be severe public health problems. Micronutrients such as vitamins and minerals are essential to the human body, and in iduals must meet their daily requirements through dietary sources. Micronutrients act as immunomodulators and protect the host immune response, thus preventing immune evasion by pathogenic organisms. Several experimental investigations have been undertaken to appraise the immunomodulatory functions of vitamins and minerals. Based on these experimental findings, this review describes the immune-boosting functionalities of micronutrients and the mechanisms of action through which these functions are mediated. Deficiencies of vitamins and minerals in plasma concentrations can lead to a reduction in the performance of the immune system functioning, representing a key contributor to unfavorable immunological states. This review provides a descriptive overview of the characteristics of the immune system and the utilization of micronutrients (vitamins and minerals) in preventative strategies designed to reduce morbidity and mortality among patients suffering from immune invasions or autoimmune disorders.

Abstract: Mitochondria are the powerhouse of cells, which upon dysfunctions may lead to several diseases. Mycotoxins are the toxic secondary metabolites from fungi which are capable of causing diseases and death in humans and animals. They have a versatile mechanism of action in biological systems and can be used as lead compounds to treat some diseases including cancer. The present work encompasses analysis on the effects of mycotoxins on mitochondrial dysfunction. Electronic databases such as PubMed, ScienceDirect, Scopus, Web of Science, and Google Scholar were thoroughly searched for up-to-date published information associated with those mycotoxins and their effect on mitochondrial dysfunction. Findings suggest that mycotoxins such as citrinin, aflatoxin, and T-2 toxin exert multi-edged sword-like effects in test systems causing mitochondrial dysfunction. Mycotoxins can induce oxidative stress even at low concentration/dose that may be one of the major causes of mitochondrial dysfunction. On the other hand, activation of apoptotic caspases and other proteins by mycotoxins may lead to apoptotic cell death. Thus, mycotoxins-mediated mitochondrial dysfunction may be related to several chronic diseases which also makes these mycotoxins considerable as lead compounds for inducing toxic effects in cells. Their cytotoxic effects on cancer cells suggest their possible application as chemotherapeutic tools. © 2018 IUBMB Life, 70(11):1084-1092, 2018.

Abstract: Diterpenes and their derivatives have many biological activities, including anti-inflammatory and immunomodulatory effects. To date, several diterpenes, diterpenoids, and their laboratory-derived products have been demonstrated for antiarthritic activities. This study summarizes the literature about diterpenes and their derivatives acting against rheumatoid arthritis (RA) depending on the database reports until 31 August 2021. For this, we have conducted an extensive search in databases such as PubMed, Science Direct, Google Scholar, and Clinicaltrials.gov using specific relevant keywords. The search yielded 2708 published records, among which 48 have been included in this study. The findings offer several potential diterpenes and their derivatives as anti-RA in various test models. Among the diterpenes and their derivatives, andrographolide, triptolide, and tanshinone IIA have been found to exhibit anti-RA activity through erse pathways. In addition, some important derivatives of triptolide and tanshinone IIA have also been shown to have anti-RA effects. Overall, findings suggest that these substances could reduce arthritis score, downregulate oxidative, proinflammatory, and inflammatory biomarkers, modulate various arthritis pathways, and improve joint destruction and clinical arthritic conditions, signs, symptoms, and physical functions in humans and numerous experimental animals, mainly through cytokine and chemokine as well as several physiological protein interaction pathways. Taken all together, diterpenes, diterpenoids, and their derivatives may be promising tools for RA management.

Abstract: The diterpene lactone andrographolide, isolated from Andrographis paniculata, has been proven to possess several important protective biological activities, including antioxidant, anti-inflammatory, immunomodulatory, antiseptic, antimicrobial, cytotoxic, hypolipidemic, cardioprotective, hepatoprotective, and neuroprotective effects. In addition, it has been reported to play a therapeutic role in the treatment of major human diseases, such as Parkinson's disease, rheumatoid arthritis, and colitis. This systematic review aims to highlight andrographolide as a promising agent in cancer treatment. To this purpose, a number of databases were used to search for the cytotoxic/anticancer effects of andrographolide in pre-clinical and clinical studies. Among 1703 identified literature articles, 139 were included in this review 109 were investigated as non-clinical, whereas 24, 3, and 3 were pre-clinical, clinical, and non-pre-clinical trials, respectively. Among the model systems, cultured cell lines appeared as the most frequently (79.14%) used, followed by in vivo models using rodents, among others. Furthermore, andrographolide was found to exert cytotoxic/anticancer effects on almost all types of cell lines with the underlying mechanisms involving oxidative stress, cell cycle arrest, anti-inflammatory and immune system mediated effects, apoptosis, necrosis, autophagy, inhibition of cell adhesion, proliferation, migration, invasion, anti-angiogenic activity, and other miscellaneous actions. After careful consideration of the relevant evidence, we suggest that andrographolide can be one of the potential agents in the treatment of cancer in the near future.

Abstract: Nanotechnology is reshaping health care strategies and is expected to exert a tremendous impact in the coming years offering better healthcare facilities. It has led to not only therapeutic drug delivery feasibility but also to diagnostics. Materials in the size of nano range (1-100 nm) used in the design, fabrication, regulation, and application of therapeutic drugs or devices are classified as medical nanotechnology and nanopharmacology. Delivery of more complex molecules to the specific site of action as well as gene therapy has pushed forward the nanoparticle-based drug delivery to its maximum. Areas that benefit from nano-based drug delivery systems are cancer, diabetes, infectious diseases, neurodegenerative diseases, blood disorders and orthopedic-related ailments. Moreover, development of nanotherapeutics with multi-functionalities has a considerable potential to fill the gaps that exist in the present therapeutic domain. In cancer treatment, nanomedicines have superiority over current therapeutic practices as they can effectively deliver the drug to the affected tissues, thus reducing drug toxicities. Along this line, polymeric conjugates of asparaginase and polymeric micelles of paclitaxel have recently been recommended for the treatment of various types of cancers. Nanotechnology-based therapeutics and diagnostics provide greater effectiveness with less or no toxicity concerns. Similarly, diagnostic imaging holds promising future applications with newer nano-level imaging elements. Advancements in nanotechnology have emerged to a newer direction which use nanorobotics for various applications in healthcare. Accordingly, this review comprehensively highlights the potentialities of various nanocarriers and nanomedicines for multifaceted applications in diagnostics and drug delivery, especially the potentialities of polymeric nanoparticle, nanoemulsion, solid-lipid nanoparticle, nanostructured lipid carrier, self-micellizing anticancer lipids, dendrimer, nanocapsule and nanosponge-based therapeutic approaches in the field of cancer. Furthermore, this article summarizes the most recent literature pertaining to the use of nano-technology in the field of medicine, particularly in treating cancer patients.

Abstract: Omeprazole (OME) is a proton pump inhibitor used for the treatment of various gastric and intestinal disease however, studies on its effects on the genetic materials are still restricted. The present study aimed to evaluate possible toxicogenic effects of OME in Allium cepa meristems with the application of cytogenetic biomarkers for DNA damage, mutagenic, toxic and cytotoxic effects. Additionally, retinol palmitate (RP) and ascorbic acid (AA) were also co-treated with OME to evaluate possible modulatory effects of OME-induced cytogenetic damages. OME was tested at 10, 20 and 40 μg/mL, while RP and AA at 55 μg/mL and 352.2 μg/mL, respectively. Copper sulphate (0.6 μg/mL) and dechlorinated water were used as positive control and negative control, respectively. The results suggest that OME induced genotoxicity and mutagenicity in A. cepa at all tested concentrations. It was noted that cotreatment of OME with the antioxidant vitamins RP and/or AA significantly (p < 0.05) inhibited and/or modulated all toxicogenic damages induced by OME. These observations demonstrate their antigenotoxic, antimutagenic, antitoxic and anticitotoxic effects in A. cepa. This study indicates that application of antioxidants may be useful tools to overcome OME-induced toxic effects.

Abstract: Cancer is a dreadful disease causing thousands of deaths per year worldwide, which requires precision diagnostics and therapy. Although the selection of therapeutic regimens depends on the cancer type, chemotherapy remains a sustainable treatment strategy despite some of its known side-effects. To date, a number of natural products and their derivatives or analogues have been investigated as potent anticancer drugs. These drug discoveries have aimed for targeted therapy and reduced side-effects, including natural therapeutic regimens. This review introduces a prospective fungal-derived polyphenol, Hispolon (HIS), as an anticancer agent. Accordingly, this review focuses on exploring the anticancer effect of hispolon based on information extracted from databases such as PubMed, ScienceDirect, MedLine, Web of Science, and Google Scholar. A literature search in PubMed, ScienceDirect, MedLine, Web of Science, and Google Scholar was accomplished, using the keyword ‘Hispolon’, pairing with ‘cancer’, ‘cytotoxicity’, ‘cell cycle arrest’, ‘apoptosis’, ‘metastasis’, ‘migration’, ‘invasion’, ‘proliferation’, ‘genotoxicity’, ‘mutagenicity’, ‘drug-resistant cancer’, ‘autophagy’, and ‘estrogen receptor. Database-dependent findings from reported research works suggest that HIS can exert anticancer effects by modulating multiple molecular and biochemical pathways, including cell cycle arrest, apoptosis, autophagy, inhibition of proliferation, metastasis, migration, and invasion. Moreover, HIS inhibits the estrogenic activity and exhibits chemoprevention prospects, possibly due to its protective effects such as anticancer and anti-inflammatory mechanisms. To date, a number of HIS derivatives and analogues have been introduced for their anticancer effects in numerous cancer cell lines. Data obtained from this review suggest that hispolon and some of its derivatives can be promising anticancer agents, and may become plant-based cancer chemotherapeutic leads for the development of potent anticancer drugs, alone or in combination with other chemotherapeutic agents.

Abstract: Ponicidin, an ent-kaurane diterpenoid derived from Rabdosia rubescens, exhibits antitumor activities against several types of cancers. This review summarizes the botanical sources, biological activities, and biopharmaceutical profile of ponicidin. Additionally, a molecular docking study has been undertaken to correlate the interaction of this diterpenoid with biomacromolecules found in the literature. For this purpose, an up-to-date (till December 2018) literature survey was conducted using a number of databases such as PubMed, Science Direct, Web of Science, Scopus, the American Chemical Society, Clinicaltrials.gov, and Google Scholar. Findings suggest that ponicidin exerts antioxidant and anticancer activity in various test systems, including experimental animals and cultured cancer cells. Research findings revealed that anticancer mechanisms of ponicidin include antioxidant/oxidative stress induction, cytotoxic, apoptotic inductive, chemosensitizer, antiangiogenic, and antiproliferative effects. In silico study suggests that 5ITD (PI3K) was the best protein with which ponicidin interacts to exert its anticancer effect. In conclusion, ponicidin might be a promising plant-derived cancer chemotherapeutic agent.

Abstract: Natural dietary agents have attracted considerable attention due to their role in promoting health and reducing the risk of diseases including cancer. Ginger, one of the most ancient known spices, contains bioactive compounds with several health benefits. [6]-Gingerol constitutes the most pharmacologically active among such compounds. The aim of the present work was to review the literature pertaining to the use of ginger extract and [6]-gingerol against tumorigenic and oxidative and inflammatory processes associated with cancer, along with the underlying mechanisms of action involved in signaling pathways. This will shed some light on the protective or therapeutic role of ginger derivatives in oxidative and inflammatory regulations during metabolic disturbance and on the antiproliferative and anticancer properties. Data collected from experimental (in vitro or in vivo) and clinical studies discussed in this review indicate that ginger extract and [6]-gingerol exert their action through important mediators and pathways of cell signaling, including Bax/Bcl2, p38/MAPK, Nrf2, p65/NF-κB, TNF-α, ERK1/2, SAPK/JNK, ROS/NF-κB/COX-2, caspases-3, -9, and p53. This suggests that ginger derivatives, in the form of an extract or isolated compounds, exhibit relevant antiproliferative, antitumor, invasive, and anti-inflammatory activities.

Abstract: Beta (β)-caryophyllene (BCAR) is a major sesquiterpene of various plant essential oils reported for several important pharmacological activities, including antioxidant, anti-inflammatory, anticancer, cardioprotective, hepatoprotective, gastroprotective, nephroprotective, antimicrobial, and immune-modulatory activity. Recent studies suggest that it also possesses neuroprotective effect. This study reviews published reports pertaining to the neuropharmacological activities of BCAR. Databases such as PubMed, Scopus, MedLine Plus, and Google Scholar with keywords "beta (β)-caryophyllene" and other neurological keywords were searched. Data were extracted by referring to articles with information about the dose or concentration/route of administration, test system, results and discussion, and proposed mechanism of action. A total of 545 research articles were recorded, and 41 experimental studies were included in this review, after application of exclusion criterion. Search results suggest that BCAR exhibits a protective role in a number of nervous system-related disorders including pain, anxiety, spasm, convulsion, depression, alcoholism, and Alzheimer's disease. Additionally, BCAR has local anesthetic-like activity, which could protect the nervous system from oxidative stress and inflammation and can act as an immunomodulatory agent. Most neurological activities of this natural product have been linked with the cannabinoid receptors (CBRs), especially the CB2R. This review suggests a possible application of BCAR as a neuroprotective agent.

Abstract: Sedatives promote calmness or sleepiness during surgery or severely stressful events. In addition, depression is a mental health issue that negatively affects emotional well-being. A group of drugs called anti-depressants is used to treat major depressive illnesses. The aim of the present work was to evaluate the effects of quercetin (QUR) and linalool (LIN) on thiopental sodium (TS)-induced sleeping mice and to investigate the combined effects of these compounds using a conventional co-treatment strategy and in silico studies. For this, the TS-induced sleeping mice were monitored to compare the occurrence, latency, and duration of the sleep-in response to QUR (10, 25, 50 mg/kg), LIN (10, 25, 50 mg/kg), and diazepam (DZP, 3 mg/kg, i.p.). Moreover, an in silico investigation was undertaken to assess this study’s putative modulatory sedation mechanism. For this, we observed the ability of test and standard medications to interact with various gamma-aminobutyric acid A receptor (GABAA) subunits. Results revealed that QUR and LIN cause dose-dependent antidepressant-like and sedative-like effects in animals, respectively. In addition, QUR-50 mg/kg and LIN-50 mg/kg and/or DZP-3 mg/kg combined were associated with an increased latency period and reduced sleeping times in animals. Results of the in silico studies demonstrated that QUR has better binding interaction with GABAA α3, β1, and γ2 subunits when compared with DZP, whereas LIN showed moderate affinity with the GABAA receptor. Taken together, the sleep duration of LIN and DZP is opposed by QUR in TS-induced sleeping mice, suggesting that QUR may be responsible for providing sedation-antagonizing effects through the GABAergic interaction pathway.
