[A new fatty acid methyl ester from Fissistigma oldhamii inhibiting proliferation of synoviocytes].

ABSTRACT

A new fatty acid methyl ester (1) was isolated from an EtOH extract of Fissistigma oldhamii. It structures was elucidated by a combination of HR-ESI-MS, 1D NMR, 2D NMR, UV, and IR spectroscopic data. The inhibitory effect of compound 1 on the proliferation of primary synovial cells was evaluated. As a result, it showed inhibitory effect on the proliferation of synoviocytes, with IC50 value of 38.6 µmol·L⁻¹.
