摘要

Since some patients with eosinophilia-myalgia syndrome ingested tryptophan along with benzodiazepines, we investigated whether demoxepam, the N-desalkylated compound of chlordiazepoxide, would influence the binding of tryptophan to hepatic nuclei. L-Tryptophan has been shown to bind (saturable, stereospecific, and of high affinity) to rat hepatic nuclei and nuclear envelopes. We report that demoxepam has an inhibitory effect on in vitro [3H]tryptophan binding to rat hepatic nuclei and has an apparent KD approximately 22 microM.
