The possibility of interactions between natural products/supplements and conventional prescription medicines is one of the most important issues in pharmacotherapeutic safety. Recently, we reported that some terpenoids such as (R)-(+)-citronellal and glycyrrhetic acid, which are present in herbal
Neoadjuvant treatment options for human epidermal growth factor receptor-2 (HER-2)-enriched and luminal B molecular subtypes of clinical breast cancer include HER-2-targeted therapy with chemotherapy or anti-hormonal therapy. These treatment options result in systemic toxicity and acquired tumor
BACKGROUND
The approval of Taxol® in 1993 marked the great entrance of terpenoids in the anti-cancer area and this drug is still highly important in the treatment of refractory ovarian, breast and other cancers. Over decades, other prominent natural terpenoids have become indispensable for the
Klugine (1), isocephaeline (2), and emetine (4) inhibited hypoxia-inducible factor-1 (HIF-1) activation by hypoxia in T47D breast tumor cells (IC(50) values 0.2, 1.1, and 0.11 muM, respectively). Compounds 1, 2, and 4 inhibited both hypoxia- and iron chelator-induced HIF-1 activation by blocking
Breast cancer (BCA) represents the highest incidence of death in 35- to 60-year-old women. Above all, hormone unresponsive BCA is still associated with poorer prognosis than hormone receptor expressing malign, mammary tumors. There is a consistent need for effective compounds to treat especially the
From Chloranthus multistachys, three terpenoids - lupeol (1), henrilabdane B (2), and istanbulin A (3) were isolated. Structures of compounds were established by NMR and MS. We reported here that ISTA (3) suppressed cell invasion, but lupeol (1) and henrilabdane B (2) did not. Furthermore, ISTA
Cancer chemoprevention is defined as the use of natural or synthetic agents that reverse, suppress or arrest carcinogenic and/or malignant phenotype progression towards invasive cancer. Phytochemicals obtained from vegetables, fruits, spices, herbs and medicinal plants, such as terpenoids,
Metabolic engineering of heterologous pathways has allowed the production of therapeutically important compounds in microbial systems. Here, we report the engineering of a monoterpenoid biosynthetic pathway into Escherichia coli. Five genes encoding sequential enzymes for perillyl alcohol
Two new terpenoids including a cadinane sesquiterpene (1), and an ent-kaurane diterpene diglycoside (2), together with a known triterpene containing 32 carbons (3), have been isolated from the ethanolic extract of Cremastra appendiculata. Their structures were established by the spectroscopic
The novel marine terpenoid dehydrothyrsiferol (DHT) has been isolated from a Canarian red alga Laurencia viridis sp. nov (Ceramiales, Rhodomelaceae) (1). Its cytotoxicity against three human breast cancer cell lines, namely T47D, ZR-75-1, and Hs578T was examined and compared with the
Anticancer efficacy and the mechanism of action of α-santalol, a terpenoid isolated from sandalwood oil, were investigated in human breast cancer cells by using p53 wild-type MCF-7 cells as a model for estrogen receptor (ER)-positive and p53 mutated MDA-MB-231 cells as a model for ER-negative breast
Alpha-santalol, a terpenoid found in sandalwood oil has been shown to inhibit breast cancer cell growth in vitro by inducing apoptosis, but the mechanisms underlying the growth inhibitory effects of alpha-santalol are not fully understood. In this study, we demonstrate that α-santalol treatment
The genus Dendronephthya encompasses marine soft corals that produce a wide spectrum of biofunctional terpenoids. Anticancer properties of these metabolites are widely exploited as potential chemotherapeutic agents. The present study reports the purification and isolation of a potential
BACKGROUND
α-Santalol, a terpenoid found in sandalwood oil, has been shown to inhibit cancer cell growth in vitro by inducing apoptosis. This study was performed to investigate the anticancer properties of α-santalol associated with the induction of apoptosis in cultured MCF-7 [estrogen receptor
Euphorbia kansui is a commonly used traditional Chinese medicine for the treatment of edema, pleural effusion, and asthma, etc. According to the previous researches, terpenoids in E. kansui possess various biological activities, e.g., anti-virus, anti-allergy, antitumor effects. In this work, twenty
