1. RES-1149-1 and -2, novel non-peptidic endothelin type B receptor antagonists produced by Aspergillus sp. II. Structure determination and derivatization
Y Uosaki, M Yoshida, T Ogawa, Y Saitoh J Antibiot (Tokyo). 1996 Jan;49(1):6-12. doi: 10.7164/antibiotics.49.6.
The structures of two novel non-peptidic endothelin type B receptor antagonists, RES-1149-1 and -2 were determined by spectroscopic methods. Several derivatives were synthesized from RES-1149-1 for biological assay.
2. Drimane sesquiterpenoids from the fungus Aspergillus ustus isolated from the marine sponge Suberites domuncula
Hongbing Liu, RuAngelie Edrada-Ebel, Rainer Ebel, Yao Wang, Barbara Schulz, Siegfried Draeger, Werner E G Müller, Victor Wray, Wenhan Lin, Peter Proksch J Nat Prod. 2009 Sep;72(9):1585-8. doi: 10.1021/np900220r.
Seven new drimane sesquiterpenoids (1-3, 6-9), along with the known compounds deoxyuvidin B (4), strobilactone B (5), and RES-1149-2 (10), were obtained from cultures of the fungus Aspergillus ustus, which was isolated from the marine sponge Suberites domuncula. Their structures were established by means of spectroscopic analyses including one- and two-dimensional NMR spectroscopy and high-resolution MS. Compounds 6, 7, and 10 showed cytotoxic activity against a panel of tumor cell lines, including L5178Y, HeLa, and PC12 cells, with 7 being the most active (EC(50) against L5178Y cell line: 0.6 microg/mL).
3. Synthesis and endothelin receptor binding activity of synthetic analogues of RES-1149-2

A direct synthesis of analogues 6 and 7 is described. The key transformations are the addition of dibromomethyl lithium to a ketone and the subsequent mild hydrolysis to a hemiacetal.
