Methods: According to the mechanism of cough reflex, the c-fibres's role in the respiratory system, and the principle of isosterism. Here, a peripheral antitussive LD was regarded as a lead compound. Amino functional groups, as substituents at the 1-hydroxy group of the racemate of LD, were introduced into the structure of the molecule. These novel compounds were confirmed by 1H-NMR, MS spectrum. Their antitussive activities were studied on mice in sequential method. The EDT50, the stimulating time that caused cough by NH3 on half of mice, were measured. Then could caculated the ratio R between the EDT50 of the treated groups and control group.
