WebOct 20, 2005 · Thus, luteophanol D ( 1) was assigned as a luteophanol B congener lacking one methylene between C-52 and C-54 of luteophanol B. Luteophanol D ( 1) possesses two tetrahydropyran rings and twenty-three hydroxyl groups on a C 63 -1inear carbon chain with one exo-methylene and two methyl branches. WebFeb 1, 2024 · It binds to SH group in the specific cysteine residue of NF-κB components with its epoxide moiety to inhibit DNA binding. In the present research, we have designed and synthesized an epoxide-free analog called (S)-β-salicyloylamino-α-exo-methylene-ƴ-butyrolactone (SEMBL, 3). SEMBL inhibited DNA binding of NF-κB component p65 in vitro.
