A series of new halophenols were synthesized, and their structures were established on the basis of 1H, 13C
NMR and mass spectral data. All of the prepared compounds were screened for their in vitro protein tyrosine kinase
(PTK) and vascular smooth muscle cell (VSMC) proliferation inhibitory activity. Twelve halophenols showed significant
PTK inhibitory activity, most of them exhibited stronger activities than that of genistein, a positive reference compound.
Several halophenols also displayed moderate VSMC proliferation inhibitory activity, compound 8c showed higher activity
than that of tetrandrine, a positive reference compound. The preliminary structure–activity relationships of these compounds
were investigated and discussed. The results provided a foundation for the action mechanism study and further
structure optimization of the halophenols.
