The binding of [3H]5-hydroxytryptamine (5-HT) to rat enteric membranes was inhibited by the inclusion of 5-HT 2-methyl-5-HT, 5-hydroxytryptophan, N,N,N-triethyltryptamine and 2-Br-N,N-diethyltryptamine in the incubation buffer. In contrast, tryptamine, 5-methoxytryptamine and 2-methyl-N,N-diethyltryptamine enhanced binding. Ascorbate and dithiothreitol facilitated and reduced binding

A capillary column gas-liquid chromatography selected ion monitoring-based method was developed for the measurement of [13C,15N]N-methyltryptamine ( NMT ) in human urine. The method was employed to establish the extent of conversion of [13C,15N]tryptamine to the correspondingly labeled NMT in

The occurrence of N-methylated tryptamine derivatives in bergamot plant (Citrus bergamia Risso et Poit) is reported for the first time. Interestingly, the most abundant of these substances is N,N,N-trimethyltryptamine, which has not been previously identified in any citrus plant. The
Direct and indirect methods are described to combine steady-state and picosecond time-resolved fluorescence decay data to generate decay-associated excitation spectra. The heterogeneous fluorescence from a fluorophore mixture that models protein fluorescence was resolved into individual component excitation spectra. The two
