New Phenylpropanoids and Disulphides Dimers from Ferula Kuhistanica.

Five undescribed compounds, including three phenylpropanoid derivatives, 4'-methoxycinnamyl isobutyrate (1), 4'-methoxycinnamyl-2"-methyl butyrate (2) and (2Z)-3',4'-dimethoxycinnamyl isovalerate (3) and two disulphides dimers, kuhistanicasulphide A (7) and kuhistanicasulphide B (8) together with five known ones, including three phenylpropanoids (4-6) and two disulphides (9-10), were isolated from the roots of Ferula kuhistanica Korovin. Their structures were elucidated on the basis of spectroscopic analysis, including IR, UV, HRESIMS, NMR and quantum 13C NMR DP4+ probability. Anti-inflammatory and cytotoxic (Hela, A549 and HT-29 cell lines) activities of the obtained compounds was tested, which compounds 4 and 5 demonstrated good anti-inflammatory with IC50 values of 25.41±2.30 μM and 31.70±3.82 μM, respectively.
