α-Aminoxy acid conjugates and hybrid α-aminoxy dipeptide conjugates showing blue to green fluorescence (with quantum yields 0.23-0.71) were synthesized (75-92% yield) from N-acylbenzotriazoles. 7-Methoxycoumarin derivatives were obtained (quantum yields φ 0.35-0.71) that could be suitable for peptide assays. The wavelengths of the absorption maxima (λAbs) and the fluorescence emission maxima (λEm)

The invention is directed to a method for the production of taxanes by culturing suspension cells of
Taxus
sp. in a nutrient medium that comprises an indanoyl amino acid. The indanoyl amino acid may be added in batch mode or in a feed stream at any time of the culturing. In particular, synthetic compounds 6-Ethyl-indanoyl-isoleucine, 6-Bromoindanoyl isoleucine and 1-oxo-indane-carboxy-(L)-Isoleucine-methyl ester amide (1-OII) have been found to increase taxane production from
Taxus
cell cultures.

Transgenic host cells, vectors useful for making transgenic host cells, and kits useful for making transgenic host cells are described. Also described are transgenic plants. In some embodiments, transgenic host cells express a 4-hydroxyphenylacetaldehyde synthase (4HPAAS). In some embodiments, transgenic host cells express a tyrosol:UDP-glucose 8-O-glucosyltransferase (T8GT). The transgenic host cells are useful for biosynthesis of one or more of salidroside, icariside D2, tyrosol, and 4-hydroxypenylacetaldehyde.
