    • Muriceanol, a 24(28)-epoxide sterol link in the carbon flux toward side-chain dealkylation of sterols 
      Lorenzo, Manuel; Cueto, Mercedes; D'Croz, Luis; Maté, Juan L.; San Martín Barrientos, Aurelio; Darías, José (WILEY-V C H VERLAG GMBH, 2006-01-30)
      Side-chain-oxidized C-28-sterol 1 and one new pregnane metabolite 2 were isolated from eastern Pacific Muricea spp. The C-24(28)-epoxide functionality is a key intermediate in the C-24-dealkylation mechanism of the conversion ...
    • Pyranosylmagellanicus a novel structural class of polyhalogenated acetogenins from Ptilonia magellanica 
      Lorenzo, Manuel; Cueto, Mercedes; San Martín Barrientos, Aurelio; Fajardo, Víctor; Darías, José (PERGAMON-ELSEVIER SCIENCE, 2005-10-03)
      Three naturally occurring pyranosyl-like polyhalogenated metabolites 1-3 as well as their likely biogenetic precursor, the linear compound 4, have been isolated from the red alga Ptilonia magellanica. They are the first ...
    • Secondary metabolites from marine penicillium brevicompactum 
      Rovirosa, Juana; Díaz Marrero, Ana; Darías, José; Painemal, Karin; San Martín Barrientos, Aurelio (SOCIEDAD CHILENA DE QUIMICA, 2006-03)
      In a screening of Basidiomycete cultures isolated from marine invertebrates collected along the Chilean coastline for the production of antibiotics we identified a Penicillium brevicompactum strain as a producer of metabolites ...
