The luminescence properties of harmine 7 methoxy 1 methyl 9 h pyrido 3 4 b indole


, : The luminescence properties of harmine 7 methoxy 1 methyl 9 h pyrido 3 4 b indole. Canadian Journal of Spectroscopy 29(4): 104-108

The absorption and emission study on harmine in different media has established the existence of the various molecular species of harmine. In addition to the neutral molecule, spectral data are shown for the cation, anion and tautomer species. Spectroscopic comparison with harmane and .beta.-carboline showed that all 3 compounds undergo an excited state proton transfer process.

A potent mutagen, 3-amino-1-methyl-5H-pyrido[4,3-b]indole (Trp-P-2), isolated from a tryptophan pyrolysate, was activated metabolically by rat liver microsomes and bound to DNA. An active metabolite formed by rat liver microsomes was identified as...

The formation of mutagenic derivatives from TrpP1 and TrpP2 by rat intestinal enzymes was observed in the intestinal S9 fraction in the Ames test. TrpP2 produced more mutagenic derivatives than TrpP1. The intestinal mutagenic activation of both Tr...
