Autor: Fabián Amaya García, Maria Leonisa Sanchez Nuñez, Freddy A. Ramos, Mónica Puyana, Izabel Christina Nunes de Palmer Paixão, Valeria Laneuville Teixeira, Leonardo Castellanos

Publikováno v: Revista Colombiana de Química, Vol 46, Iss 1, Pp 5-12 (2017)

Los dolabellanos son diterpenos con importante actividad antiviral, la mayor parte de los estudios se han realizado con compuestos aislados de algas pardas del género Dictyota. Los corales blandos son también una importante fuente de dolabellanos,

Synthesis of 2,3-Diarylquinoxaline Carboxylic Acids in High-Temperature Water

Autor: Miriam M. Unterlass, Fabián Amaya-García

Publikováno v: Synthesis. 54:3367-3382

Aromatic carboxylic acids are prone to decarboxylate in high-temperature water (HTW). While the decarboxylation kinetics of several aromatic carboxylic acids have been explored, studies on their compatibility with organic syntheses in HTW are scarce.

Brown algae and soft corals represent the main marine sources of dolabellane diterpenes. The antiviral activity of dolabellanes has been studied for those isolated from algae, whereas dolabellanes isolated from soft corals have been barely studied. I

Green Hydrothermal Synthesis of Fluorescent 2,3-Diarylquinoxalines and Large-Scale Computational Comparison to Existing Alternatives

Autor: Stefan Kubicek, Miriam M. Unterlass, Anna Koren, Jörg Menche, Fabián Amaya-García, Michael Caldera

Publikováno v: Chemsuschem

Here, the hydrothermal synthesis (HTS) of 2,3‐diarylquinoxalines from 1,2‐diketones and o‐phenylendiamines (o‐PDAs) was achieved. The synthesis is simple, fast, and generates high yields, without requiring any organic solvents, strong acids o

Screening of acetylcholinesterase inhibitors in marine organisms from the Caribbean Sea

Autor: Fabián Amaya-García, Edisson Tello, Leonardo Castellanos, Mónica Puyana, Fabio Castellanos, Adriana Umaña, Jackson A. L. C. Resende, Freddy A. Ramos

The acetylcholinesterase inhibitory activity of 89 organic extracts from marine organisms was evaluated through a TLC bioautography methodology. Extracts from soft corals (Eunicea and Plexaura) were the most active compared with extracts from sponges

Dolabellane diterpenes have considerable antiviral activity, but most studies have been focused towards compounds isolated from Dictyota brown algae. Although soft corals are also a significant source of these diterpenes, their antiviral potential ha
