Chemistry of LSZ: An In-depth Analysis

Lysergic acid 2,4-dimethylazetidide (LSZ), also known as d-lysergic acid 2,4-dimethylazetidide, belongs to the semi-synthetic alkaloid family of lysergamides, characterized by a core structure of lysergic acid with an amine functional group bound to RN within its chemical composition.

Structural Composition

The fundamental structure of LSZ comprises a polycyclic arrangement, rooted in lysergic acid and featuring an indole derivative. This intricate composition incorporates tryptamine and phenethylamine groups. Specifically, a bicyclic hexahydroindole is fused to a bicyclic quinoline group (lysergic acid). At carbon 8 of the quinoline, an amide group is attached. Furthermore, the substitutions of the terminal nitrogen atom of the amide group create a 2,4-dimethylazetidide group. An additional methyl group is situated at carbon 6 of the structure.

Stereoisomers and Pharmacological Activity

Within the azetidine ring, LSZ presents three possible stereoisomers, with the (S,S)-(+) isomer exhibiting the highest activity. In drug discrimination tests utilizing trained rats, this isomer demonstrates slightly greater potency than LSD itself. Understanding the pharmacological nuances of LSZ's stereochemistry is crucial for comprehending its effects and potential applications in research.
