title: QSAR studies on psychotomimetic phenylalkylamines.
abstract: Attempts have been made to correlate hyperthermic potencies in rabbits and LSD-like effect in rat of a series of phenylisopropylamines (amphetamines) with physico-chemical parameters. In case of 2,4,5-trisubstituted analogs, hyperthermic potencies are found to be well correlated parabolically with the hydrophobic parameter pi. However, for the same series, the LSD-like effect is found to be related with pi in combination of steric parameter of 4-substituent. It is therefore inferred that hyperthermia in rabbit may be the function only of the hydrophobic character of molecule, but the LSD-like effect is influenced by the steric hindrance of 4-substituent also.
