Diphenylterazine elicits minimal cell toxicity at millimolar concentrations[1].
Diphenylterazine (DTZ) has high quantum yield, red-shifted emission, favorable in vivo pharmacokinetics and lacks cofactors required for light emission. Yeh AH (2023) used Diphenylterazine (DTZ) as the target substrate of luciferase, and the multinuclear transport factor NTF2-like superfamily as the target topology, to de novo design a small and stable protein scaffold to make the size and shape of the pocket suitable for Diphenylterazine. This method screens out designed luciferases with high selectivity and overcomes the limitations of natural proteins. The catalytic efficiency of the de novo designed luciferase for Diphenylterazine (kcat/Km = 106/M/s) is comparable to that of natural luciferase, but the substrate specificity is higher[2].
Notes: To make a stock solution for DTZ (Diphenylterazine), first, a premixture is prepared by dissolving 17.6 mg of L-ascorbic acid (HY-B0166) in 10 mL ethanol and 10 mL 1,2-propanediol; next, 1 mg of Diphenylterazine is dissolved in 88 μL of the premix, resulting in a 30 mM Diphenylterazine stock solution containing 5 mM L-ascorbic acid.
The stock solution should be stable for a few months in -80°C freezers. It may also be aliquoted to 10-20 μL each at -80°C for the convenience of use. We want to note that this new formulation greatly enhances substrate stability, compared to the conventional acidic alcohol solution[3].

1. Female nude mice were injected subcutaneously with HeLa cells[4].
2. Diphenylterazine (0.3 μmol (0.113 mg); 100 μL) was injected intravenously on days 1, 3, 5, 7, 14, and 28 after tumor implantation.
3. Approximately 5 minutes later, images were taken using a bioluminescence imaging system.

Luminescence emission spectra of DTZ in the presence (blue) and absence (green) of LuxSit.

Dimeric SEC peak was observed when LuxSit-i was concentrated to a high concentration (~50 μM) in Tris pH 8.0 buffer. Both dimeric and monomeric SEC fractions showed the expected size on SDS–PAGE and both peaks were catalytically active to emit luminescence in the presence of 25 μM DTZ.

Protokoll
BALB/c mice are used and transfected with cells expressing teLuc, Antares, Antares2 and FLuc by injecting cells into the tail vein of BALB/c mice. After the diminishing of the FLuc bioluminescence, 0.3 µmol Diphenylterazine or furimazine is intraperitoneally injected. Mice are imaged with a 1-min exposure per frame over a course of 20 min. The images are processed using the Fiji image analysis software and the frames with highest signals in individual experiments are used for comparison[1].
