Hydrofurimazine is a NanoLuc substrate whose enhanced aqueous solubility allows delivery of higher doses to mice. Hydrofurimazine enables sensitive bioluminescence imaging for either prolonged light production of high sensitivity[1].
Prolonged light production with Hydrofurimazine makes it the optimal substrate for dynamic reporters such as CaMBI, while the intensity of light production with fuorofurimazine makes it well suited for tasks where sensitivity is important such as visualizing tumor growth, viral spread or gene expression[1].

Novel NanoLuc substrates enable bright two-population bioluminescence imaging in animals
Nat Methods 2020 Aug;17(8):852-860.PMID:32661427DOI:10.1038/s41592-020-0889-6.
Sensitive detection of two biological events in vivo has long been a goal in bioluminescence imaging. Antares, a fusion of the luciferase NanoLuc to the orange fluorescent protein CyOFP, has emerged as a bright bioluminescent reporter with orthogonal substrate specificity to firefly luciferase (FLuc) and its derivatives such as AkaLuc. However, the brightness of Antares in mice is limited by the poor solubility and bioavailability of the NanoLuc substrate furimazine. Here, we report a new substrate, Hydrofurimazine, whose enhanced aqueous solubility allows delivery of higher doses to mice. In the liver, Antares with Hydrofurimazine exhibited similar brightness to AkaLuc with its substrate AkaLumine. Further chemical exploration generated a second substrate, fluorofurimazine, with even higher brightness in vivo. We used Antares with fluorofurimazine to track tumor size and AkaLuc with AkaLumine to visualize CAR-T cells within the same mice, demonstrating the ability to perform two-population imaging with these two luciferase systems.
NanoBiT System and Hydrofurimazine for Optimized Detection of Viral Infection in Mice-A Novel in Vivo Imaging Platform
Int J Mol Sci 2020 Aug 15;21(16):5863.PMID:32824188DOI:10.3390/ijms21165863.
Reporter genes are used to visualize intracellular biological phenomena, including viral infection. Here we demonstrate bioluminescent imaging of viral infection using the NanoBiT system in combination with intraperitoneal injection of a furimazine analogue, Hydrofurimazine. This recently developed substrate has enhanced aqueous solubility allowing delivery of higher doses for in vivo imaging. The small high-affinity peptide tag (HiBiT), which is only 11 amino-acids in length, was engineered into a clinically used oncolytic adenovirus, and the complementary large protein (LgBiT) was constitutively expressed in tumor cells. Infection of the LgBiT expressing cells with the HiBiT oncolytic virus will reconstitute NanoLuc in the cytosol of the cell, providing strong bioluminescence upon treatment with substrate. This new bioluminescent system served as an early stage quantitative viral transduction reporter in vitro and also in vivo in mice, for longitudinal monitoring of oncolytic viral persistence in infected tumor cells. This platform provides novel opportunities for studying the biology of viruses in animal models.
Evaluation of NanoLuc substrates for bioluminescence imaging of transferred cells in mice
J Photochem Photobiol B 2021 Mar;216:112128.PMID:33529963DOI:10.1016/j.jphotobiol.2021.112128.
NanoLuc luciferase recently gained popularity due to its small size and superior bioluminescence performance. For in vivo imaging applications, NanoLuc has been limited by its substrate furimazine, which has low solubility and bioavailability. Herein, we compared the performances of recently reported NanoLuc luciferase substrates for in vivo imaging in mice. Two substrates with improved aqueous solubility, Hydrofurimazine and fluorofurimazine, were evaluated along with three stabilized O-acetylated furimazine analogues, the hikarazines. All 5 analogues, when tested in vitro, displayed greater signal intensity and reaction duration, in comparison to the standard NanoLuc substrate, furimazine. The two best-performing analogues from the in vitro study were selected for further in vivo testing. The NanoLuc/fluorofurimazine pair demonstrated the highest bioluminescence intensity, post intravenous administration. It was found to be around 9-fold brighter compared to the NanoLuc/furimazine and 11-fold more intense than the NanoLuc/hikarazine-003 pair, with an average of 3-fold higher light emission when the substrate was injected intraperitoneally, in a subcutaneous model. Excitingly, despite the fact that NanoLuc/fluorofurimazine emits mostly blue light, we prove that cells trapped in mice lungs vasculature could be visualised via the NanoLuc/fluorofurimazine pair and compare the results to the AkaLuc/AkaLumine system. Therefore, among the tested analogues, fluorofurimazine enables higher substrate loading and improved optical imaging sensitivity in small animals, upgrading the use of NanoLuc derived bioluminescent systems for deep tissue imaging.
