Identification of interaction partners of novel polyacetylene


ABSTRACT: To elucidate molecular interaction partners of a novel plant-derived polyacetylene, we used a biotin-labelled polyacetylene in two cell lines (HEK293 and HepG2) and performed biotin-pulldown assays and proteomic analyses via LC-MSMS.

To ameliorate or even prevent signatures of aging in ultimately humans, we here report the identification of a previously undescribed polyacetylene contained in the root of carrots (Daucus carota), hereafter named isofalcarintriol, which we reveal as potent promoter of longevity in the nematode C. elegans. We assign the absolute configuration of the compound as (3 S,8 R,9 R,E)-heptadeca-10-en-4,6-diyne-3,8,9-triol, and develop a modular asymmetric synthesis route for all E-isofalcarintriol stere  ...[more]
