Bivalent and polyvalent inhibitors can be used as antitumor agents. In this experiment, eight ligustrazine dimers and seven ligustrazine tetramers linked by alkane diamine with different lengths of carbon chain lengths were synthesized. After screening their antiproliferation activities against five cancer cell lines, most ligustrazine derivatives showed better cytotoxicity than the ligustrazine monomer

Noncyclic polyethers containing two cinnamoyl end groups have been prepared, they were cyclized by photosensitized intramolecular addition. The uptake of alkali metal (sodium and potassium) thiocyanates with these compounds and their ability to extract has been investigated before and after the cyclization.
