    Exploring the molecular mechanism of karrikins and strigolactones
    摘要:
    Karrikins and strigolactones are novel plant growth regulators that contain similar molecular features, but very little is known about how they elicit responses in plants. A tentative molecular mechanism has previously been proposed involving a Michael-type addition for both compounds. Through structure-activity studies with karrikins, we now propose an alternative mechanism for karrikin and strigolactone mode of action that involves hydrolysis of the butenolide ring.

    The selective catalytic oxidation of monosaccharides was applied to butyl xylosides and butyl glucosides leading to the formation of bioactive karrikins, molecules that are important in the response to catastrophic fires. Butanosolv processing of biomass provides a co-product stream that contains these starting materials providing relevance to this work in the biorefinery context.

With an aim to indentify new lead structures for the bc1 complex, a series of novel inhibitors were discovered from the natural product karrikinolide for the first time. Extensive screening results suggested variable inhibitory activities of these compounds against succinate-cytochrome reductase [SCR, a mixture of respiratory complex II (SQR) and complex III (the bc1 complex)], implying
