Synthesis of silyl peroxide of coelenterazine (oplophorus luciferin) analogue for precursor of luminescence
摘要:
Unstable tert-butyldimethylsilyl peroxide of coelenterazine (Oplophorus luciferin) analogue has been synthesized by radical reaction of tert-butyldimethylsilyl hydroperoxide. This compound may be a key intermediate model in the bioluminescence and chemiluminescence of coelenterazine.

Chemiluminescent characters of 2-hydroperoxide 2 and 1,2-dioxetanone 6 of coelenterate luciferin analog 1 prepared by low-temperature photooxygenation are described. Direct luminescence by thermal decomposition of 2 or 6 was independently observed, suggesting that the former emitted light as anionic amide 4, on the other hand, the latter as neutral one 7.
Unstable hydroperoxide of coelenterazine (Oplophorus luciferin) analog has been synthesized by the reaction of coelenterazine analog with polymer-bound Rose Bengal via photooxygenation. This compound may be a key intermediate model in the bioluminescence of aequorin and the chemiluminescence of coelenterazine.
postulated intermediates in chemiluminescentreactions of coelenterate luciferin, Cypridina luciferin, and its analogues. The 5-hydroperoxide analogue emitted weak light in chemiluminescentreactions in several solvent systems. However, it did not generale any amide. This research leads to the conclusion that 5-hydroperoxide is not an important intermediate in chemiluminescentreactions.

A coelenterazine analog was photo-oxygenated at -78 degrees C to give luminous intermediates. Irradiation in a mixed polar solvents as CF3CH2OH and MeOH with C-13-labeled analogs afforded the first evidence assignable to dioxetanone structure.
