N-substituted aliphatic heterocyclic compounds able to facilitate the passage of active substances through physiological barriers.

摘要

N-substituted aliphatic heterocyclic compounds having the following general formula: <CHEM> where Y is CH2, S, S>0 or 0; m and n are whole numbers between 0 and 10 and such that their sum is a whole number between 3 and 10; R is a C6-C20 linear or branched alkyl or an acyl of general formula - @-R1 in which R1 is a C5-C19 linear or branched alkyl; and a process for their production. Said compounds have low toxicity, and high capacity in facilitating the passage of active substances through physiological barriers. Said compounds also possess anti-inflammatory and antiallergic activity.
