dluciferin 6′methyl ether

D-Luciferin 6′-methyl ether (also known as 6′-Methoxyluciferin or compound 19a) is a highly effective inhibitor of luciferase obtained from the North American firefly Photinus pyralis (referred to as PpyLuc). It exhibits an IC50 value of 0.1 μM. This compound, which is an analog of D-luciferin, interacts non-specifically with the ATP and luciferin binding sites within the active site of PpyLuc.
