RESUMO
The root and stem bark extracts of a Nigerian sample of Leptonychia pubescens Keay (Sterculiaceae) were found to inhibit the serine protease tryptase, a potential therapeutic target for the treatment of asthma and chronic obstructive pulmonary disease (COPD). Bioassay-guided isolation led to the identification of 1-beta-ribofuranosylbrunfelsamidine as the active component with a tryptase IC (50) of 3 microM. Brunfelsamidine was also isolated, but was only weakly active.
