Abstract:
Objective To study the lignans chemical constituents from Diaphragma Juglandis Fructus and their activity of inhibiting HIV. Methods The constituents were isolated from Diaphragma Juglandis Fructus and purified by column chromatography, and the structures were identified by spectra analysis and chemical methods.The activity of anti-HIV-1 were detected by LEDGF/p75-IN proteins complex ELISA kit. Results Sixteen compounds were isolated from Diaphragma Juglandis Fructus and the structures were identified as (-)-syringaresinol (1), (+)-pinoresinol (2), (+)-(7R,7’R,7″S,7’’’S,8S,8’S,8″S,8’’’S)-4″,4’’’-dihydroxy-3,3’,3″,3’’’,5,5’- hexamethoxy-7,9’;7’,9-diepoxy-4,8″;4’,8’’’-bisoxy-8,8’-dineolignan-7″,7’’’,9″,9’’’-tetraol (3), 2,3-dihydroxy-1-(4’-hydroxy-3’-methoxy- phenyl)-propan-1-one (4), 3-hydroxy-1-(4’-hydroxy-3’-methoxyphenyl)-propan-1-one (5), 3’,4’-dimethoxyphenylpropanediol (6), (2S)-3,3-di-(4-hydroxy-3-methoxyphenyl)-propane-1,2-diol (7), 3-hydroxy-1-(4’-hydroxy-3’,5’-dimethoxy phenyl)-propan-1-one (8), (1R,5R,6R)-6-{4’-O-[8″-(7″-(4″-hydroxy-3″-methoxyphenyl)) glyceol]-3’,5’-dimethoxyphenyl}-3,7-dioxabicyclo [3.3.0] octan-2-one (9), curcasinlignan B (10), evofolin-B (11), (7S,8R)-dihydrodehydrodiconiferyl alcohol (12), pinnatifidanin C I (13), (+)-(7S,8S)-4,1’-dihydroxy-3,3’,5’-trimethoxy-7,8,9-trinor-8,4’-oxyneolignan-7,9-diol (14), dysosmarol (15), and 1-(4’-hydroxy-3’-methoxyphenyl)-2- [4″-(3-hydroxypropyl)-2″,6″-dimethoxyphenoxy]-propane-1,3-diol (16). Conclusion All compounds are isolated from Diaphragma Juglandis Fructus for the first time. Compound 13 has the potential activity of inhibiting HIV-1.
