Two high-molecular water-soluble preparations with high anticomplementary, antioxidant, antilipoperoxidant and antiinflammatory activities were isolated from the roots of Symphytum asperum and S. caucasicum. Their main chemical constituent was found to be poly[oxy-1-carboxy-2-(3,4-dihydroxyphenyl)ethylene], according to IR and NMR spectroscopy. The Symphytum high-molecular preparations can modulate in vitro B- chronic lymphocytic leukaemia (B-CLL) cells apoptosis and cell cycle progression. 相似文献

Three new phenylethanoid glycosides, named digicilisides A – C ( 1 – 3 , resp.), have been isolated from the roots of Digitalis ciliata, along with five known phenylethanoid glycosides. The structures of 1 – 3 were identified as 2‐(4‐hydroxy‐3‐methoxyphenyl)ethyl β‐d ‐glucopyranosyl‐(1→3)‐[α‐l ‐rhamnopyranosyl‐(1→6)]‐4‐O‐[(E)‐feruloyl]‐β‐d ‐glucopyranoside ( 1 ), 2‐(3,4‐dihydroxyphenyl)ethyl α‐l ‐arabinopyranosyl‐(1→2)‐[β‐d ‐glucopyranosyl‐(1→3)]‐[α‐l ‐rhamnopyranosyl‐(1→6)]‐4‐O‐[(E)‐feruloyl]‐β‐d ‐glucopyranoside ( 2 ), and 2‐(3,4‐dihydroxyphenyl)ethyl β‐d ‐glucopyranosyl‐(1→3)‐{6‐O‐[(E)‐feruloyl]‐β‐d ‐glucopyranosyl‐(1→6)}‐4‐O‐[(E)‐caffeoyl]‐β‐d ‐glucopyranoside ( 3 ). 相似文献

17α-Amino-5ga-androst-2-ene was synthesized from epiandrosterone via formation of the tosylate followed by nucleophilic substitution
by azide and reduction with LiAlH4. The structures of the products were proved by NMR and IR spectroscopy and mass spectrometry.

Some 5α-type steroidal derivatives of the steroidal sapogenin tigogenin were synthesized. The structures of the synthesized
derivatives were characterized by spectral methods and elemental analysis. The antituberculosis activity of the compounds
toward Mycobacterium tuberculosis strain H37Rv was studied in vitro (Microplate Alamar Blue Assay) in BACTEC 12B medium and
was compared with that of isoniazide. Some of the synthesized compounds exhibited high (92-98%) antimycobacterial activity.
