Abstract
An increasing amount of evidence has demonstrated the anticancer activity of triterpenes extracted from traditional medicines. Echinocystic acid (EA), a natural triterpene isolated from Eclipta prostrata (L.) L., has previously been shown to exhibit anticancer activity in HepG2 and HL-60 cells. The aim of the present study was to investigate the anticancer activity of EA in non-small cell lung cancer (NSCLC) cells. For this purpose, the viability and proliferation of A549 cells were determined using a Cell Counting Kit-8 and 5-ethynyl-2'-deoxyuridine staining. The migratory and invasive ability of the A549 cells were measured using wound healing and Transwell assays. Hoechst staining was also performed to detect the apoptosis of A549 cells. The proliferation of A549 cells and the distributions of different growth phases were determined using a flow cytometer. Western blot analysis was used to detect the expression levels of cyclin D, partitioning defective 3 homolog (Par3), PI3K, Akt, mTOR, Bax, Bcl-2 and caspase-3. EA inhibited the proliferation, and the migratory and invasive abilities of cultured lung carcinoma cells (A549 cells), and induced cell cycle arrest in the G1 phase of the cell cycle. Treatment with EA upregulated Par3 expression and inhibited the PI3K/Akt/mTOR pathway in vitro. In addition, EA treatment inhibited tumor growth, suppressed proliferation and induced the apoptosis of tumor cells in NSCLC tumor xenografts in mice. On the whole, these results suggest that EA may represent a potential therapeutic agent for NSCLC.

Abstract
Drug discovery from natural sources is going through a renaissance, having spent many decades in the shadow of synthetic molecule drug discovery, despite the fact that natural product-derived compounds occupy a much greater chemical space than those created through synthetic chemistry methods. With this new era comes new possibilities, not least the novel targets that have emerged in recent times and the development of state-of-the-art technologies that can be applied to drug discovery from natural sources. Although progress has been made with some immunomodulating drugs, there remains a pressing need for new agents that can be used to treat the wide variety of conditions that arise from disruption, or over-activation, of the immune system; natural products may therefore be key in filling this gap. Recognising that, at present, there is no authoritative article that details the current state-of-the-art of the immunomodulatory activity of natural products, this in-depth review has arisen from a joint effort between the International Union of Basic and Clinical Pharmacology (IUPHAR) Natural Products and Immunopharmacology, with contributions from a Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation number of world-leading researchers in the field of natural product drug discovery, to provide a "position statement" on what natural products has to offer in the search for new immunomodulatory argents. To this end, we provide a historical look at previous discoveries of naturally occurring immunomodulators, present a picture of the current status of the field and provide insight into the future opportunities and challenges for the discovery of new drugs to treat immune-related diseases.
