- Sclerofish A and B: Two Pairs of Enantiomeric Diterpenoids Featuring a 4/7/6-Fused Tricyclic Scaffold from the Soft Coral . Luu, Phuong Vu Phan, Thuy-Tien Thi Huynh, Quoc-Dung Tran Pham, Ngoc-Thac Le, Huong-Giang Chen, Lo-Yun Ton-Nu, Huong Lien Nguyen, Cuong-Quoc Shen, Yao-An Fan, Yu-Jui Su, Jui-Hsin Peng, Bo-Rong Lai, Kuei-Hung Two pairs of enantiomeric diterpenoids, (±)-sclerofish A () and (±)-sclerofish B (), featuring a rare 4/7/6-fused tricyclic framework, were isolated from the soft coral by molecular networking-guided isolation. Their structures were elucidated by comprehensive spectroscopic analyses, including NMR, HRESIMS, TDDFT-ECD, and DP4+ analysis. A plausible biogenetic pathway, originating from geranylgeranyl pyrophosphate (GGPP) was proposed to rationalize the formation of the unusual bicyclo[4.3.1]decane subunit and the resulting 4/7/6-fused skeleton. Compound exhibited inhibition of Huh-7 cells with IC values of 5.1 ± 0.9 and 4.9 ± 0.3 μM, respectively, and showed selective cytotoxicity toward cancer cells (SI > 9.7), whereas compound displayed comparatively weaker activity. These findings expand the structural diversity of xeniaphyllane-type diterpenoids and highlight the soft coral as a valuable source of structurally unique and biologically relevant marine natural products.
