N-sec-butyl Lysergamide / Lysergic acid 2-butyl amide (LSB) is an analogue of Lysergic acid diethyl amide (LSD) originally developed by Richard Pioch at Eli Lilly in the 1950s and more recently known by the research conducted David E. Nichols at Purdue University and his team. It is a structural isomer of LSD, and is* scheduled in USA. *
The sec-butyl group has the same molecular formula as the diethylamine with the molecule as a whole.
It is one of the few lysergamide derivatives to exceed the potency of LSD in animal drug discrimination assays, with the (R) isomer having an ED50 of 33nmol/kg for producing drug-appropriate responding, vs 48nmol/kg for LSD itself.
