New antitumor bicyclic hexapeptides, RA-XI, -XII, -XIII and -XIV from Rubia cordifolia.[Pubmed: 1394660]

METHODS AND RESULTS:
Four new bicyclic hexapeptides, named as RA-XI, -XII, XIII and -XIV were isolated from Rubia cordifolia and showed potent antitumor activities against P-388. The structures were elucidated from spectroscopic and chemical evidences.
CONCLUSIONS:
RA-XII, XIII and -XIV were proved to be unique bicyclic hexapeptidic glucosides.
