  • Title: A minor dihydropyran apocarotenoid from mated cultures of Blakeslea trispora.
    Author: Barrero AF, Herrador MM, Artega P, González JA, Arteaga JF.
    Journal: Molecules; 2012 Oct 24; 17(11):12553-9. PubMed ID: 23095897.
    Abstract:
    The heterocyclic C15 apocarotenoid 1 was isolated from mated cultures of the strains F986 (+) and F921 (−) of Blakeslea trispora. This new compound formed during sexual interaction is a minor constituent of the culture media and its structure was elucidated by spectroscopic data, including 2D-NMR. A plausible biosynthetic pathway involving a double degradation of β-carotene, followed by several oxidations of the resulting monocyclofarnesane C15 fragment is proposed.
