In this work on the design and studies of luciferins related to the blue-hued coelenterazine, the synthesis of heterocyclic analogues susceptible to produce a photon, possibly at a different wavelength, is undertaken. Here, the synthesis of O-acetylated derivatives of imidazo[1,2-b]pyridazin-3(5 H)-one, imidazo[2,1-f][1,2,4]triazin-7(1 H)-one, imidazo[1,2-a]pyridin-3-ol, imidazo[1,2-a]quinoxalin-1(5 H)-one, benzo[f]imidazo[1,2-a]quinoxalin-3(11 H)-one, imidazo[1′,2′:1,6]pyrazino[2,3-c]quinolin-3(11 H)-one, and 5,11-dihydro-3 H-chromeno[4,3-e]imidazo[1,2-a]pyrazin-3-one is described thanks to extensive use of the Buchwald–Hartwig N-arylation reaction. The acidic hydrolysis of these derivatives then gave solutions of the corresponding luciferin analogues, which were studied. Not too unexpectedly, even if these were “dressed” with substituents found in actual substrates of the nanoKAZ/NanoLuc luciferase, no bioluminescence was observed with these compounds. However, in a phosphate buffer, all produced a light signal, by chemiluminescence, with extensive variations in their respective intensity and this could be increased by adding a quaternary ammonium salt in the buffer. This aspect was actually instrumental to determine the emission spectra of many of these luciferin analogues.

Treatment of oxazolone 1 with hydrazine hydrate at room temperature gave the (Z)-configurated isomer hydrazide (Z)-3 (high yield). However, refluxing 1 with hydrazine hydrate yielded the (E)-configurated isomer hydrazide (E)-2 (low yield).The hydrazide derivative (Z)-3 has been utilized as synthon for the synthesis of 1,2,4-triazinone, imidazolone, and oxadiazole derivatives through appropriate routes. The thiosemicarbazide and semicarbazide derivatives are synthesized by different routes. The structures of the new compounds were established on the basis of IR, 1H-NMR, mass spectral data, and elemental analysis.

New hydrazone incorporated triazines were designed and synthesized using an appropriate synthetic route with regard to essential pharmacophores, and evaluated for their anticonvulsant activity through maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole-induced seizure (scPTZ) screenings. Among the tested compounds, 4-[{2-(5-(3-chlorobenzyl)-3-phenyl-1,2,4-triazine-6-yl)hydrazono} methyl]-N,N-dimethylaniline 6k (MES ED50 54.31, scPTZ ED50 92.01) and 4-[{2-(5-(4-chlorobenzyl)-3-phenyl-1,2,4-triazine-6-yl)hydrazono}methyl]-N,N-dimethylaniline 6r (MES ED50 46.05, scPTZ ED50 83.90) emerged as the most active anticonvulsant agents having GABAergic effects. Compounds 6k and 6r also showed lesser CNS depressant effect than the standard drug carbamazepine. To obtain further insights into the binding interactions of these molecules, molecular docking studies were carried out.
Application to photoreactive materials of photochemical generation of superbases with high efficiency based on photodecarboxylation reactions

A thin film of polystyrene containing 4c was spin-coated on a CaF2 plate and irradiated with 365 nm light. The absorption band arising from the carboxylate of 4c at 1372 cm-1 in the FTIR spectrum decreased after UV irradiation. Radical UV curing materials that are well established in the marketplace have drawbacks because of high volume shrinkage and oxygen inhibition. The anionically cured film showed high transparency and no volume shrinkage, in contrast to a conventional radical UV curing system, which showed large volume shrinkage. This is probably due to relatively low quantum yields for photobase generation and weaker basicity of photo-generated bases, leading to low photosensitivity of photoreactive materials sensitized with photobase generators. Furthermore, many of the photobase generators reported are generally prepared via several synthetic steps.
