1. RES-1149-1 and -2, novel non-peptidic endothelin type B receptor antagonists produced by Aspergillus sp. I. Taxonomy of producing strain, fermentation, isolation, and physico-chemical and biological properties
T Ogawa, K Ando, T Tanaka, Y Uosaki, Y Matsuda J Antibiot (Tokyo). 1996 Jan;49(1):1-5. doi: 10.7164/antibiotics.49.1.
RES-1149-1 and -2, novel and non-peptidic endothelin antagonists, were isolated from the cultured broth of a fungus, Aspergillus sp. RE-1149. RES-1149-1 and -2 selectively inhibited the ET-1 binding to endothelin type B receptor (ETB receptor) with IC50 values of 1.5 microM and 20 microM, respectively. Taxonomy of producing strains, fermentation, isolation, and physico-chemical properties of RES-1149-1 and -2 are described.

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.
3. RES-1149-1 and -2, novel non-peptidic endothelin type B receptor antagonists produced by Aspergillus sp. III. Biochemical properties of RES-1149-1, -2 and structure-activity relationships
T Ogawa, Y Uosaki, T Tanaka, E Tsukuda, A Mihara, Y Matsuda J Antibiot (Tokyo). 1996 Feb;49(2):168-72. doi: 10.7164/antibiotics.49.168.
RES-1149-1 and -2, produced by Aspergillus sp. RE-1149, were found to be non-peptidic antagonists for endothelin type B receptor (ET(B) receptor). RES-1149-1 and -2 selectively inhibited the endothelin-1 (ET-1) binding to ET(B) receptor in a competitive manner with IC50 values of 1.5 microM and 20 microM, respectively. RES-1149-1 inhibited the increase in intracellular Ca2+ concentration elicited by 1 nM ET-1 in COS-7 cells expressing human ET(B) receptor, but not in the case of cells expressing ET(A) receptor. In addition, some structure-activity relationships are described.
