WebIn an amazing feat of in vivo chemistry that remains somewhat mysterious, the firefly synthesizes D-luciferin in a multi-step process from L-cysteine and benzoquinone . In the laboratory, D-luciferin and aminoluciferin analogs are typically synthesized by the condensation of an electron-deficient nitrile with D-cysteine (Figure 3). Web2. Synthesis of D-luciferin The chemical structure of D-luciferin (1), isolated from firefly tails, was proposed in 19618 and later confirmed by synthesis.9 In this procedure, p-anisidine (4) is the starting material that, through intermediates 5 and 6, is transformed into the thioacid 7, in turn cyclized to 6-methoxybenzothiazole-2-carboxylic ...
WebNov 1, 2024 · Bioluminescent is a standard noninvasive technique for in vivo imaging.
