Abstract
Natural products, a rich source of bioactive chemical compounds, have served humans as a safer drug of choice since times. Eriocalyxin B, an ent-Kaurene diterpenoid, has been extracted from a traditional Chinese herb Isodon eriocalyx. Experimental data support the anticancer and anti-inflammatory activities of EriB. This natural entity exhibits anticancer effects against breast, pancreatic, leukemia, ovarian, lung, bladder, and colorectal cancer. EriB has capability to inhibit the proliferation of cancer cells by prompting apoptosis, arresting cell cycle, and modulating cell signaling pathways. The regulation of signaling pathways in cancerous cells by EriB involves the modulation of various apoptosis-related factors (Bak, Bax, caspases, XIAP, survivin, and Beclin-1), transcriptional factors (nuclear factor kappa B [NF-κB], STAT3, Janus-activated kinase 2, Notch, AP-1, and lκBα), enzymes (cyclooxygenase 2, matrix metalloproteinase 2 [MMP-2], MMP-9, and poly (ADP-ribose) polymerase), cytokines, and protein kinases (mitogen-activated protein kinase and ERK1/2). This review proposes that EriB supplies a novel opportunity for the cure of cancer but supplementary investigations along with preclinical trials are obligatory to effectively figure out its biological and pharmacological applications.

BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 16:384. [PMID: 27716288 PMCID: PMC5045602 DOI: 10.1186/s12906-016-1358-8] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/19/2016] [Accepted: 09/08/2016] [Indexed: 02/07/2023]
Abstract
Background Natural products are valuable sources for anticancer agents. In the present study, methylferulate (MF) was identified for the first time from Tamarix aucheriana. Spectral data were used for identification of MF. The potential of MF to control cell growth, cell cycle, apoptosis, generation of reactive oxygen species (ROS), cancer cell invasion, nuclear factor kappa B (NFkB) DNA-binding activity and proteasomal activities, as well as the enhancement of chemosensitivity in human colorectal cancer cells, were evaluated. The possible molecular mechanism of MF’s therapeutic efficacy was also assessed. Methods Column chromatography and spectral data were used for isolation and identification of MF. MTT, immunofluorescence, flow cytometry, in vitro invasion, fluoremetry, EIA and Real time qPCR were used to measure antiproliferative, chemo-sensitizing effects and other biochemical parameters. Results MF showed a dose-dependent anti-proliferative effect on colorectal cancer cells (IC50 = 1.73 – 1.9 mM) with a nonsignificant cytotoxicity toward normal human fibroblast. Colony formation inhibition (P ≤ 0.001, 0.0001) confirmed the growth inhibition by MF. MF arrested cell cycle progression in the S and G2/M phases; induced apoptosis and ROS generation; and inhibited NF-kB DNA-binding activity, proteasomal activities and cell invasion in colorectal cancer cells. MF up-regulated cyclin-dependent kinase inhibitors (p19 INK4D, p21WAF1/CIP1, p27KIP1), pro-apoptotic gene expression (Bax, Bad, Apaf1, Bid, Bim, Smac) and caspases (caspase 2, 3, 6, 7, 8, 9). Moreover, MF down-regulated cyclin-dependent kinases (Cdk1, Cdk2) and anti-apoptotic gene expression (c-IAP-1, c-IAP-2, Bcl2,FLIP). In addition, MF differentially potentiated the sensitivity of colorectal cancer cells to standard chemotherapeutic drugs. Conclusion MF showed a multifaceted anti-proliferative and chemosensitizing effects. These results suggest the chemotherapeutic and co-adjuvant potential of MF.

Abstract
Cancer is a multi-faceted disease comprised of a combination of genetic, epigenetic, metabolic and signalling aberrations which severely disrupt the normal homoeostasis of cell growth and death. Rational developments of highly selective drugs which specifically block only one of the signalling pathways have been associated with limited therapeutic success. Multi-targeted prevention of cancer has emerged as a new paradigm for effective anti-cancer treatment. Platycodin D, a triterpenoid saponin, is one the major active components of the roots of Platycodon grandiflorum and possesses multiple biological and pharmacological properties including, anti-nociceptive, anti-atherosclerosis, antiviral, anti-inflammatory, anti-obesity, immunoregulatory, hepatoprotective and anti-tumour activities. Recently, the anti-cancer activity of platycodin D has been extensively studied. The purpose of this review was to give our perspectives on the current status of platycodin D and discuss its anti-cancer activity and molecular mechanisms which may help the further design and conduct of pre-clinical and clinical trials to develop it successfully into a potential lead drug for oncological therapy. Platycodin D has been shown to fight cancer by inducing apoptosis, cell cycle arrest, and autophagy and inhibiting angiogenesis, invasion and metastasis by targeting multiple signalling pathways which are frequently deregulated in cancers suggesting that this multi-target activity rather than a single effect may play an important role in developing platycodin D into potential anti-cancer drug.

Abstract
Extracellular polymeric substance (EPS) is a substance secreted during algal growth, which has been found to have numerous health-promoting effects. In the present study, A431 human epidermoid carcinoma cells were selected as target cells and cultivated in vitro as an experimental model to investigate the anti-cancer effect of extracellular polymeric substances from Aphanizomenon flos-aquae (EPS-A) and the possible underlying mechanism. Apoptosis- and cell cycle-associated molecules as well as the mitochondrial membrane potential of the cells were quantified using flow cytometry (FCM). FCM showed that EPS-A induced cell cycle arrest, which led to a loss of mitochondrial function of the A431 cells and an increase in necrotic and late apoptotic cells. In order to evaluate the apoptosis and cell viability, acridine orange/ethidium bromide staining was used, morphological changes were observed using fluorescence microscopy and typical apoptotic characteristics were observed. Following treatment with a high dose of EPS-A, transmission electron microscopy showed nuclear fragmentation, chromosome condensation, cell shrinkage and expansion of the endoplasmic reticulum; apoptotic bodies were also observed. In conclusion, EPS-A caused cell cycle arrest, stimulated cell apoptosis via the mitochondrial pathway and exhibited important anti-cancer activity.

Abstract
Cancer is the second leading cause of deaths worldwide. Despite concerted efforts to improve the current therapies, the prognosis of cancer remains dismal. Highly selective or specific blocking of only one of the signaling pathways has been associated with limited or sporadic responses. Using targeted agents to inhibit multiple signaling pathways has emerged as a new paradigm for anticancer treatment. Icariside II, a flavonol glycoside, is one of the major components of Traditional Chinese Medicine Herba epimedii and possesses multiple biological and pharmacological properties including anti-inflammatory, anti-osteoporosis, anti-oxidant, anti-aging, and anticancer activities. Recently, the anticancer activity of Icariside II has been extensively investigated. Here, in this review, our aim is to give our perspective on the current status of Icariside II, and discuss its natural sources, anticancer activity, molecular targets and the mechanisms of action with specific emphasis on apoptosis pathways which may help the further design and conduct of preclinical and clinical trials. Icariside II has been found to induce apoptosis in various human cancer cell lines of different origin by targeting multiple signaling pathways including STAT3, PI3K/AKT, MAPK/ERK, COX-2/PGE2 and β-Catenin which are frequently deregulated in cancers, suggesting that this collective activity rather than just a single effect may play an important role in developing Icariside II into a potential lead compound for anticancer therapy. This review suggests that Icariside II provides a novel opportunity for treatment of cancers, but additional investigations and clinical trials are still required to fully understand the mechanism of therapeutic effects to further validate it in anti-tumor therapy.

Abstract
Natural products have been associated with significant health benefits in preventing and treating various chronic human diseases such as cancer, cardiovascular diseases, diabetes, Alzheimer's disease, and pathogenic infections. However, the isolation, characterization and evaluation of natural products remain a challenge, mainly due to their limited bioavailability. Metabolic engineering and fermentation technology have emerged as alternative approaches for generating natural products under controlled conditions that can be optimized to maximize yields. Optimization of these processes includes the evaluation of factors such as host selection, product biosynthesis interaction with the cell's central metabolism, product degradation, and byproduct formation. This review summarizes the most recent biochemical strategies and advances in expanding and diversifying natural compounds as well as maximizing their production in microbial and plants cells.

Abstract
Over the years, natural products from plants and their non-natural derivatives have shown to be active against different types of chronic diseases. However, isolation of such natural products can be limited due to their low bioavailability, and environmental restrictions. To address these issues, in vivo and in vitro reconstruction of plant metabolic pathways and the metabolic engineering of microbes and plants have been used to generate libraries of compounds. Significant advances have been made through metabolic engineering of microbes and plant cells to generate a variety of compounds (e.g. isoprenoids, flavonoids, or stilbenes) using a diverse array of methods to optimize these processes (e.g. host selection, operational variables, precursor selection, gene modifications). These approaches have been used also to generate non-natural analogues with different bioactivities. In vitro biosynthesis allows the synthesis of intermediates as well as final products avoiding post-translational limitations. Moreover, this strategy allows the use of substrates and the production of metabolites that could be toxic for cells, or expand the biosynthesis into non-conventional media (e.g. organic solvents, supercritical fluids). A perspective is also provided on the challenges for generating novel chemical structures and the potential of combining metabolic engineering and in vitro biocatalysis to produce metabolites with more potent biological activities.

Abstract
INTRODUCTION The apparent productivity crisis in the pharmaceutical industry and the economic and political rise of China have contributed to renewed interest in the application of Chinese medicine for drug discovery. AREAS COVERED The author presents an overview of the historical development and basic principles of theory and practice of Chinese herbal medicine, its materia medica and prescription formulas, and discusses the motivation for and rationale of its application to drug discovery. Furthermore, the author distinguishes the five main approaches to drug discovery from Chinese herbal medicine, based on the decreasing amount and detail of historical and clinical Chinese medicine knowledge that informed the research effort. EXPERT OPINION Many compounds that have been isolated from the Chinese materia medica exhibit pharmacological activities comparable to pharmaceutical drugs. With the exception of the antimalarial drug artemisinin, however, this knowledge has not led to the successful development of new drugs outside of China. The chance of success in a Chinese medicine-based drug discovery effort will be increased by consideration of the empirical knowledge that has been documented over many centuries in the historical materia medica and prescription literature. Most Chinese medicine-derived compounds affect more than one target and do not correspond to the one compound/one-target drug discovery paradigm. A new frontier is opening up with the development of drugs consisting of combinations of multiple compounds acting on multiple targets under the paradigm of network pharmacology. The ancient practice of combining multiple drugs in prescription formulas can serve as inspirational analogy and a practical guide.
