A fluorescent beta-carboline, 1-methyl-1,2,3,4-tetrahydro-beta-carboline-3- carboxylic acid (MTCA) was identified in human normal lenses and cataractous lenses. The mean total amounts of MTCA in normal lenses (n = 7), diabetic cataractous lenses (n = 15), and senile cataractous lenses (n =

While the pathogenesis of eosinophilia-myalgia syndrome (EMS) remains obscure, the ingestion of L-trypophan (LT) and possibly certain constituents in the LT product might be associated. We investigated the effect of chemically synthesized substances, 1,1'-ethylidene bis[tryptophan] (EBT) and its decomposition product

The excretion and distribution of 14C were studied in rats given by oral intubation 14C-labelled (-)-(1S,3S)-1-methyl-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid and its stereoisomer, (-)-(1R,3S)-1-methyl-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid (MTCAs), compounds that are known to become mutagenic on reaction with nitrite. For comparison, another group of rats

1-Methyl-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid (MTCA) is now thought to be a possible causative substance of eosinophilia-myalgia syndrome associated with ingestion of L-tryptophan. In the present study a factor affecting endogenous formation of MTCA in 32 healthy men is studied. Urinary excretions of
