The purpose of this paper is to create a resource for the future scientific study of the medical ethnobotany and bioactivity of pteridophytes on Moorea, French Polynesia. Pteridophytes comprise a small fraction of the Moorean pharmacopoeia; however they are a highly abundant resource on this tropical island. Compiled here are all the relevant data available on phytochemistry, bioactivity and me...

As an ent-kaurene diterpenoid isolated from Isodon eriocalyx var. Laxiflora, Eriocalyxin B (EriB) possesses potent bioactivity of antitumor and anti-autoimmune inflammation, which has been suggested to work through inhibition of NF-kappaB (NF-κB) signaling. However, the direct target of EriB remains elusive. In this study, we showed that EriB induced apoptosis is associated with the inhibition ...

Cancer and infectious diseases continue to be a major public health problem, and new drugs are necessary. As marine organisms are well known to provide a wide range of original compounds, the aim of this study was to investigate the bioactivity of the main constituents of the cosmopolitan red alga, Sphaerococcus coronopifolius. The structure of several bromoditerpenes was determined by extensiv...

Cancer stem cells (CSCs) are a major cause of cancer treatment failure, relapse, and drug resistance and are known to be responsible for cancer cell invasion and metastasis. The Sonic hedgehog (Shh) signaling pathway is crucial to embryonic development. Intriguingly, the aberrant activation of the Shh pathway plays critical roles in developing CSCs and leads to angiogenesis, migration, invasion...

Bioactivity-directed fractionation of extracts of two Diospyros maritima bark samples from Indonesia,one collected at sea level in a beach forest in Java and the other collected at a slight elevation away from the sea shore on the island of Lombok, yielded a diverse set of secondary metabolites. The naphthoquinone plumbagin (1), although found in extracts of both specimens, constituted a much l...

Taxodium Rich. is a genus of the family Cupressaceae. The trees are especially prized for their rot and termite resistant wood. Taxodium leaves and cones, which are particularly rich in essential oils were used as folk medicine to treat skin, gastro-intestinal, respiratory, inflammation, and infections. Preliminary bioactivity assays reported antimicrobial, antitumor, antitermitic, antispasmodi...

Gambogic acid (GA) is a natural compound derived from brownish gamboge resin that shows a range of bioactivity, such as antitumor and antimicrobial properties. Although, GA is already known to induce cell death in a variety of cancer cells, the molecular basis for GA-induced cell death in renal cancer cells is unclear. In this study, a treatment with GA induced cell death in human renal carcino...

This study aimed to construct a novel recombinant expression vector, pcDNA3.1(-)hTERT-shRNA/yCDglyTK. Its bioactivity and antitumor effects were investigated in the SGC7901 human gastric cancer cell line. Interfering RNA (RNAi) targeting human telomerase reverse transcriptase (hTERT) was applied to construct the pYr1.1-hTERT-shRNA vector. The shRNA expression cassette (including U6 promoter) wa...

The PhD work focused on the automatic extraction of small molecule bioactivity information from scientific literature, a topic that ultimately aims to contribute to the small molecule ontology ChEBI. The ChEBI ontology plays an important role in assisting biomedical research, but requires further expansion in order to improve the ability to interrelate and link ChEBI to other primary biological...
