Notes:
Indole-3-ethanol is a dietary indole present in cruciferous vegetables that has been shown to influence estradiol metabolism in humans and may provide a new chemopreventive approach to estrogen-dependent diseases. (PMID 2342128) 3-Indole ethanol has been identified as the hypnotic agent in trypanosomal sleeping sickness, and because it is formed in vivo after ethanol or disulfiram treatment, is also associated with the study of alcoholism. (PMID 7241135) [HMDB]
