Abstract:
New sesquiterpene glycoside, cyclodipeptide and piperidine derivative were isolated from Streptomyces sp. YIM 63342. On the basis of spectral data, their structures were determined as 3R, 5R, 6S, 7E, 9R-megastigman-7-en-3,5,6,9-tetrol-9-O-β-D-apiofuranosyl-(1→ 2)-β-D-glucopyranoside (1), cyclo (L-Pro-L-OMet) (2) and (R)-(E, E)-2-(l,3-pentadienyl) piperidine (3), together with three known compounds as N-acetyltyramine (4), lycoperodine-1 (5), cyclo(L-Pro-L-Tyr)(6).
