| Abstract: | The activity of the metabolic branch‐point enzyme PriA from Mycobacterium tuberculosis (mtPriA) can be controlled reversibly by light. Two‐pronged inhibitors based on the dithienylethene scaffold were designed utilizing mtPriA’s natural rotational symmetry. Switching from the flexible, ring‐open to the rigid, ring‐closed isomer reduces inhibition activity by one order of magnitude. |
