Abstract
Quantitative structure-antiulcer activity relationships of 1-(aminocarbonylalkyl)-4-benzylpiperazine derivatives (I) were analyzed by using the adaptive least-squares (ALS) technique. Discriminant functions show that (1) a bulky amide moiety is disadvantageous, (2) a small number of methylene groups between carbonyl and piperazine is favorable, (3) a substituent which has a large B1 value (or B2 value when the substituent is forced to be in the in-plane conformation) with low lipophilicity at the 3 and/or 4 position of the benzyl moiety is favorable for antiulcer activity with low acute toxicity.
