(1984)
Lead residues analysis in cabbage. Cabbage and soil samples from the main cabbage growing areas of Costa Rica were analyzed for lead residues. Lead residues result from the use of lead arseniate as an insecticide and ...
Reproducible molecular networking of untargeted mass spectrometry data using GNPS
(2020-05-13)
Global Natural Product Social Molecular Networking (GNPS) is an interactive online small molecule–focused tandem mass spectrometry (MS2) data curation and analysis infrastructure. It is intended to provide as much chemical ...
Phenolic compounds as antiangiogenic CMG2 inhibitors from costa rican endophytic fungi
(2012)
Targeting and inhibiting CMG2 (Capillary Morphogenesis Gene protein 2) represents a new strategy for therapeutic agents for cancer and retinal diseases due to CMG2’s role in blood vessel growth (angiogenesis). A high ...
Bioprospecting
(2001)
Bioprospecting is the systematic search for genes, natural compounds designs and whole organisms in wild life with a potential for product development by biological observation and biophsical, biochemical, and genetic ...
Identification of Protein Kinase C Activation as a Novel Mechanism for RGS2 Protein Upregulation through Phenotypic Screening of Natural Product Extracts
(2014)
Biochemical high-throughput screening is widely used in drug discovery, using a variety of small molecule libraries. However, broader screening strategies may be more beneficial to identify novel biologic mechanisms. In ...
Organic Acids without a Carboxylic Acid Functional Group
(Journal of Chemical Education 77(7):910-915. July 2000, 2000-07)
This paper presents several organic molecules that have been labeled as acids but do not contain a carboxylic acid functional group. The rationale for the nomenclature and appropriate explanations for the apparent acidity ...
Flavonoid and other constituents of Bauhinia manca
(1988)
Phytochemical analysis of the stem of Bauhiniu munca yielded 63 compounds, among them six new natural products. Major constitutents were found to be 3-0-galloylepicatechin, gallic acid, cinnamic acid, /3-sitosterol and its ...
Gaschromatographische Analyse des Samenfettes der mittelamerikanischen Fevillea Cordifolia (Cucurbitaceae)
Gaschromatographic Analysis of the Seed Fat of the Middle American Fevillea cordifolia (Cucurbitaceae)
(1992)
The fat of the seeds of Fevillea cordifolia was extracted under exclusion of oxygen and light and then characterized by 13C-NMR in regard to the contained unsaturated acid moieties. The total fat was separated by HPLC to ...
Bis(μ2-benzoato-κ2O,O′)bis(benzoato-κO)bis(ethanol-κO)bis(μ3-hydroxido)hexakis(μ-pyrazolato-κ2N,N′)hexacopper(II) ethanol disolvate
(2019)
Trinuclear copper–pyrazolate entities are present in various Cu-based enzymes and nanojar supramolecular arrangements. The reaction of copper(II) chloride with pyrazole (pzH) and sodium benzoate (benzNa) assisted by ...
