Two new lissoclinamides, lissoclinamides 9 and 10 were isolated from an Indonesian collection of the ascidian Lissoclinum patella along with the known patellamide C. The structures of the lissoclinamides were determined by a combination of 2D NMR, selective 1D TOCSY, MS and MSn techniques. The assignment of absolute stereochemistry was achieved by the hydrolysis of lissoclinamides 9 and 10 followed by chiral TLC. In the case of lissoclinamide 9, NOE restrained molecular dynamics studies were also performed confirming the proposed stereochemistry. (C) 2000 Elsevier Science Ltd. All rights reserved.
