A Photoactivatable Small-Molecule Probe for the In Vivo Capture of Polyketide Intermediates.


ABSTRACT: A photolabile carba(dethia) malonyl N-acetylcysteamine derivative was devised and prepared for the trapping of biosynthetic polyketide intermediates following light activation. From the lasalocid?A polyketide assembly in a mutant strain of the soil bacterium Streptomyces lasaliensis, a previously undetected cyclised intermediate was identified and characterised, providing a new outlook on the timing of substrate processing.
