“…Normally, this highly regulated and self-limiting phenomenon promotes the healing process. However, uncontrolled and pro-longed process, called as chronic inflammation, may cause sustained activation of immune cells resulted in high amount of cytokine release [344,345]. This persistent response potentially leads to pathological disorders such as autoimmune diseases, diabetes, heart diseases, cancer and various neurodegenerative disorders.…”

Piper species are aromatic plants used as spices in the kitchen, but their secondary metabolites have also shown biological effects on human health. These plants are rich in essential oils, which can be found in their fruits, seeds, leaves, branches, roots and stems. Some Piper species have simple chemical profiles, while others, such as Piper nigrum, Piper betle, and Piper auritum, contain very diverse suites of secondary metabolites. In traditional medicine, Piper species have been used worldwide to treat several diseases such as urological problems, skin, liver and stomach ailments, for wound healing, and as antipyretic and anti-inflammatory agents. In addition, Piper species could be used as natural antioxidants and antimicrobial agents in food preservation. The phytochemicals and essential oils of Piper species have shown strong antioxidant activity, in comparison with synthetic antioxidants, and demonstrated antibacterial and antifungal activities against human pathogens. Moreover, Piper species possess therapeutic and preventive potential against several chronic disorders. Among the functional properties of Piper plants/extracts/active components the antiproliferative, anti-inflammatory, and neuropharmacological activities of the extracts and extract-derived bioactive constituents are thought to be key effects for the protection against chronic conditions, based on preclinical in vitro and in vivo studies, besides clinical studies. Habitats and cultivation of Piper species are also covered in this review. In this current work, available literature of chemical constituents of the essential oils Piper plants, their use in traditional medicine, their applications as a food preservative, their antiparasitic activities and other important biological activities are reviewed.

“…In our study, GR24 enhanced the expression of the Nrf2-dependent antioxidant genes Nqo1 and heme oxygenase 1, which are known to block inflammatory pathways 24 . GR24 has recently been shown to alleviate inflammation and upregulate these two NRF2 target genes in hepatic and macrophage cells 19 .…”

“…We have demonstrated that GR24 ameliorates insulin sensitivity, stimulates mitochondrial biogenesis and ATP production and upregulates genes regulating mitochondrial function in L6 myotubes 10 . Very recently, the efficacy of GR24 in promoting cytoprotective responses via Nrf2 activation was reported in hepatic and macrophage cell lines 19 . This work reports a transcriptomic study revealing the potential beneficial effects of GR24 in upregulating Nrf2 and its target genes involved in detoxification, carbohydrate and lipid metabolism, heme metabolism, NADPH regeneration and oxidative stress in L6 myotubes, thus contributing to metabolic homeostasis.…”

GR24 is a synthetic strigolactone analog, demonstrated to regulate the development of plants and arbuscular mycorrhizal fungi. GR24 possesses anti-cancer and anti-apoptotic properties, enhances insulin sensitivity and mitochondrial biogenesis in skeletal myotubes, inhibits adipogenesis, decreases inflammation in adipocytes and macrophages and downregulates the expression of hepatic gluconeogenic enzymes. Transcription factor Nrf2 (Nuclear factor (erythroid-derived 2)-like 2) is a master regulator of antioxidant response, regulating a multitude of genes involved in cellular stress responses and anti-inflammatory pathways, thus maintaining cellular redox homeostasis. Nrf2 activation reduces the deleterious effects of mitochondrial toxins and has multiple roles in promoting mitochondrial function and dynamics. We studied the role of GR24 on gene expression in rat L6 skeletal muscle cells which were differentiated into myotubes. The myotubes were treated with GR24 and analyzed by microarray gene expression profiling. GR24 upregulated the cytoprotective transcription factor Nrf2 and its target genes, activating antioxidant defences, suggesting that GR24 may protect skeletal muscle from the toxic effects of oxidative stress.

“…Chronic inflammation refers to the uncontrolled immune response of living organisms to initiate a defense mechanism against several endogenous and exogenous stimuli [84,85,86]. However, a prolonged inflammatory response is associated with the production of an excess amount of reactive nitrogen/oxygen species, persistent cytokine release and sustained immune response [85,87]. This might lead to various inflammation-related pathological diseases including type II diabetes, coronary-neurologic disorders, as well as cancer [88,89].…”

Cancer is a heterogeneous disease and one of the major issues of health concern, especially for the public health system globally. Nature is a source of anticancer drugs with abundant pool of diverse chemicals and pharmacologically active compounds. In recent decade, some natural products and synthetic analogs have been investigated for the cancer treatment. This article presents the utilization of natural products as a source of antitumor drugs.
