“…Analysis of the HMBC correlations (Table 3, Figure 4) for the left portion of 4 revealed that two chelated hydroxy protons resonating at δ H 12.76 and 13.17 were attributed to 9-OH and 10-OH, respectively. The olefinic proton (δ H 6.20) was assigned as H-6 on the basis of its 3 from the methyl protons (H 3 -12′, δ H 2.24) to C-6′ (δ C 132.9) and C-8′ attached this methyl group at C-7′. A 2-oxopropyl unit was established and located at C-6′ on the basis of the HMBC correlations of H 2 -9′ (δ H 3.93) and H 3 -11′ (δ H 2.30), as demonstrated in Figure 4.…”

“…They have produced a broad range of secondary metabolites that show various biological activities. Some of them are the antifungal fungerin, the antibacterial and cytotoxic neomangicols, and the anti- Helicobacter pylori methylsulochrin . We have recently reported the investigation of sea fan-derived fungi that yielded the antibacterial nigrospoxydon A and nigrosporapyrone A .…”

“…Some of them are the antifungal fungerin, 1 the antibacterial and cytotoxic neomangicols, 2 and the anti-Helicobacter pylori methylsulochrin. 3 We have recently reported the investigation of sea fan-derived fungi that yielded the antibacterial nigrospoxydon A 4 and nigrosporapyrone A. 5 In this paper, we describe the isolation and structure determination of metabolites from two sea fan-derived fungi, Fusarium spp.…”
