Fungal Endophytes and Their Bioactive Compounds in Tropical Forests of Costa Rica
(2021-04-15)
We present a glimpse of the diversity of endophytic fungi in the tropical forests of Costa Rica and some examples of bioactive compounds obtained from them. We include the characterization of isolates carried out mainly ...
Virulencia de hongos nativos del orden Hypocreales sobre Bemisia tabaci, estudio de las condiciones óptimas para el desarrollo de los hongos y registros de moscas blancas silvestres para Costa Rica
(2020)
Los hongos Hypocreales son hongos entomopatógenos con potencial en control biológico de insectos plaga. El objetivo de este estudio fue identificar especies de hongos patógenos que parasitan insectos de la familia Aleyrodidae ...
Mastering analytical challenges for the characterization of pentacyclic triterpene mono- and diesters of Calendula officinalis flowers by non-aqueous C30 HPLC and hyphenation with APCI-QTOF-MS
(2016-01-25)
Pentacyclic triterpene mono- and diesters have been isolated from Calendula officinalis flowers. GC–MS, APCI-Exactive Orbitrap HR-MS and NMR allowed to identify the triterpene skeleton in various samples (different triterpene ...
Novel Lobophorins Inhibit Oral Cancer Cell Growth and Induce Atf4- and Chop-Dependent Cell Death in Murine Fibroblasts
(2015-07-06)
As part of the International Cooperative Biodiversity Groups (ICBG) Program, we were interested in identifying biologically active unfolded protein response (UPR) inducing compounds from marine microorganisms isolated from ...
