Identification of two lysergic acid diethylamide analogs, 1-(3-(trimethylsilyl) propionyl) lysergic acid diethylamide (1S-LSD) and 1-(2-thienoyl)-6-allyl-nor-d-lysergic acid diethylamide (1T-AL-LAD), in paper sheet products distributed on the internet.

Two new LSD analogs, 1S-LSD and 1T-AL-LAD, were identified in sheet products sold in Japan. Their structures were determined using gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry, and nuclear magnetic resonance. A trace amount of iso-1S-LSD, a C8-epimerization product, was also suggested in one product. This is the first report of these compounds in sheet products in Japan. The metabolic pathways and biological activities of 1S-LSD and 1T-AL-LAD remain unexplored, and further investigation into their possible in vivo deacylation and conversion into LSD or AL-LAD is needed.
