Two Rubiaceae-type cyclopeptides, 6-O-methylbouvardin (1) and the new cyclopeptide 5ß-hydroxy-RA-III (2), were isolated from the roots of Galianthe thalictroides. Employing the sulforhodamine B assay, compounds 1 and 2 were tested in vitro against three cancer cell lines--786-0 (kidney carcinoma), PC-3 (prostate carcinoma), and HT-29 (colon carcinoma)--and showed GI50 values ranging from 0.06 to 1.80 µg mL(-1). This is the first report on the isolation of Rubiaceae-type cyclopeptides from a genus other than Rubia or Bouvardia.
