The endogenous levels of 5-methoxyindole-3-acetic acid (5-MIAA) in quail pineal gland, retina and serum were determined by capillary column gas chromatography/mass spectrometry/selected ion monitoring using a deuterated internal standard and the N-pentafluoropropionyl-O-pentafluorobenzyl ester derivative. Diurnal rhythms of pineal and serum

Daily urinary excretion of 5-hydroxy-3-indoleacetic acid (5-HIAA) and 5-methoxyindole-3-acetic acid (5-MIAA) was studied by chromatography-mass-spectrometry in patients with cancer and healthy subjects. A considerable increase in urinary 5-MIAA-excretion was shown in patients with cancer of the stomach, rectum and lung.

A series of N-trifluoroacetyl/pentafluoropropionyl-O-trifluoroethyl/ pentafluoropropyl/heptafluorobutyl ester derivatives of 5-methoxyindole-3-acetic acid (5MIAA) were synthesized. Under electron-capture negative ionization conditions, the N-trifluoroacetyl derivatives were found to yield relatively abundant, analyte-specific M-. molecular ions and [M-HF]-., [M-HF-CF2CO]-. and [M-CF3CO]- fragment ions, while the
