Aromatic constituents of Uvaria grandiflora.
Grandiuvarone A (1) and grandiuvarins A-C (2-4) were isolated from the bark of Uvaria grandiflora. The structures of these new aromatic compounds were elucidated on the basis of spectroscopic analyses, especially 2D NMR techniques. Only compound 1 exhibited antileishmanial activity, with IC(50)/IC(90) values of 0.7/1.5 microg/mL. The positive controls pentamidine and amphotericin B had IC(50)/IC(90) values of 1.6/6.6 and 0.17/0.34 microg/mL, respectively.
